A fishing line can also be used successfully. Bait the hook with an insect, bread, or other edible matter, tie the line to a tree or stick where the birds frequent.

Birds are rather difficult to shoot or trap because of their flighty nature but you may be lucky enough to locate a nest, either on the ground or in the trees, containing eggs or young. Most birds try to confuse intruders by flying away from their nest at the approach of any danger. This has the effect of leading the intruder in the wrong direction, thus protecting the eggs or young.

Emus are very common in outback areas and can be enticed towards bright objects waved by a person hiding behind a bush. As the bird's inquisitive nature leads it within metres of the object, the person can then step out and kill the bird with a suitable weapon.

When shooting or trapping, frequent a water source if possible. Stealth, not speed, is of great importance when shooting and patience at a water hole at dawn or dusk is usually rewarded.

Reptiles
All reptiles are edible including venomous snakes [remove the head and portion of the neck to remove the venom glands]. Goannas being reptiles are fatty and oily so if you have to eat these, overcook them. Remember, care must be taken when catching venomous snakes and other reptiles, as their bite can be fatal or lead to infection.

Marine Life
Fish can be caught using the usual method of a baited hook whether in the sea or inland rock holes. They can also be trapped near the water's edge by using a fence of upright sticks pushed into the sand close together. This type of fish trap is used by fishermen in tropical areas with extreme tides where netting is used in place of the sticks. The fish are trapped by the mesh of sticks and easily removed when the tide goes out. Another method of gathering sea food is by digging in the sand or turning over rocks for shellfish after the tide has receded. This is how some fishermen collect bait for line fishing.

Insects
Insects and their larvae are often overlooked as a source of food even though they are widespread and easy to obtain. One hundred grams of fried termites have a calorie value that puts them amongst the richest foods. Most other insects have a high food value and are a particularly good source of nourishment. They also have a high food value as well as a having a high fluid content. In some overseas countries, maggots, grasshoppers and termites form part of the natural diet. Termites can be obtained by breaking open anthills or dead wood and picked up on the end of a wet fingertip. The taste is in no way offensive and the same can be said for ant eggs.

The insect larvae known as the bardie or witchetty grub is obtained by breaking open dead trees and blackboy stumps after examining for the characteristic borer holes. Other insect larvae may also be present and can be eaten if there is no offensive smell or taste.

Do not eat furry grubs or grubs with black showing through the skin. Snails and slugs can be eaten but are an unlikely source of food as they favour wetter areas and there would be alternate food available.

Honey ants can be collected near the base and on the branches of trees in tropical areas. The fluid from their abdomens is good nourishment as is honey from wild bees if you are lucky enough to locate any.



ANIMAL BUTCHERY
Most animals can be eaten although most of us have a preference for herbivorous animals such as cattle sheep, pigs, horses, rabbits and poultry. There is no reason however, that you cannot eat vermin in a survival situation.

Disease
Check all animals for disease, the body should look well fed and be clean smelling. If in doubt a small piece of meat can be boiled in a covered pot, when the water is boiling if the vapours have a bad smell you should not eat the meat. Do not eat birds when the flesh is flabby, purple, a green discoloration around the neck, stiff feet, collapsed eyes or a sour smell present. If you can pull out a rabbits' fur, if its eyes are enlarged and dull or its body cavity slimy it should not be touched.



PREPARATION OF GAME FOR COOKING
The size and type of animal will determine your method of preparation for cooking.

Large Animals
Should have the throat cut to 'bleed' the carcass, then hung up by the hind legs, the gut contents, head, and skin removed then cut into joints for cooking.

Snakes
Should have the head, skin and stomach removed and be cut into small pieces.

Lizards
Are prepared simply by removing the head and gut contents.

Birds
Should have the head removed along with all the feathers and the intestines.

Rabbits
Should be skinned, gutted and have the head and feet removed before cooking.

Note: Remember to wash all meat of blood before cooking, also make sure in the interests of hygiene that you wash all blood and meat from your hands after handling dead animals.



EDIBLE PLANTS
A vast number of plants that can provide food in an emergency occur naturally in Western Australia. However, many of them are hard to identify without expert help and many more have sharp or tangy juices that discourage people who cautiously taste them.

The seeds of many of the native pea and bean family are highly poisonous. It is best to avoid these native plants even though garden varieties are good to eat. After all, if you are already working hard at surviving, you do not want to add illness to your misfortunes.

You should also avoid the palm-like plants. Zamia palm fruits contain poisons and so do the young shoots. Unless you are absolutely certain of the identity of the palms that you are about to eat they are best left alone. Fungi are another group of plants best avoided. Although many of the fungi that are found in Australia can be eaten they provide little nourishment and there is no rule to eliminate the deadly species.



THE TASTE TEST FOR PLANT EDIBILITY
Should you find vegetation that you think is edible you must carry out the taste test to reduce the chance of eating something that will harm you.

LOOK
Does it look like something you can eat, look for poison indicators such as milky sap.

SMELL
Break open, crush it and smell it, be wary of things that smell like almonds or peaches.

TOUCH
Rub on to a tender part of your body and wait 20 minutes to see if a rash develops.

TASTE
Rub on the inside of the lip and tip of the tongue, testing for flavour and reaction.

EAT
Eat a very small portion [if all the above tests prove negative] and wait a few hours to see if there are any reactions. If there is no reaction then you may eat a larger portion, continue to do this until you are sure that even large quantities will not harm you.

Note: Should the part you have tested prove inedible then do not discard it as cooking may make it edible. If one part of a plant proves to be inedible then test the rest.



SOME COMMON TYPES OF EDIBLE VEGETATION
This list gives only a few of the well-known plants that grow in Western Australia and are fairly easy to identify.

Banksia and Grevillea
Many of the flowers of the Banksia and Grevillea family contain large amounts of sweet nectar that can be sucked directly from the flower or they can be stirred in water to make a refreshing sweet drink.

Blackboy [Xanthorrhoea sp]
Has an edible white substance at the base of the green leaves, this is quite sweet when eaten raw. The plant is killed when you remove this growing heart so treat this plant strictly as emergency food.

Bracken Fern [Pteridium sp]
This and some other large ferns are edible while the green shoot is in the "fiddle head" stage. Although they can be eaten raw, they are more palatable when cooked, the underground stems although stringy are rich in starch and roast up well in the campfire.

Bulrush [Typha sp]
Is recognised by its brown flower spikes rising above the erect grass like leaves. These plants generally grow along the edges of lakes, swamps and large dams. The horizontal stems are rich in starch but need pounding to separate this from the strong fibres running through the plant.

Emu Plums [Podocarpus drouynianus]
A low shrub found in the southern forests yields a dark purple, edible fruit of good flavour. The attached green "seed" should be discarded.

Figs [Ficus sp]
Fig trees of one kind or another are found across much of Australia's inland, their glossy, green leaves are very distinctive and the red, pulpy fruits are excellent eating.

Geebungs [Persoonia sp]
These shrubs or small trees are found mainly in the south of the state. Their small fruits are edible and are tastiest when collected from beneath the tree bearing the fruit. These sticky fruits are also given the unappealing name "snotty gobble".

Kurrajongs [Brachychiton sp]
The trees have dense crowns of bright green leaves and are easily identified by their boat shaped, woody seed pods filled with shiny, yellow seeds. Use a stick to remove the seeds from their pods as the small hairs surrounding the seeds are very irritating to the skin. The seeds, rubbed free of their individual shells in a dish [hub cap] can be pounded and roasted with a little water to make porridge. Roasted until black and then crushed, the seed can be used like ground coffee to provide a drink.

Native Banana [Leichardtia Australia]
Is a vine with greyish leaves, tiny flowers and white, milky sap. Even though milky saps usually indicate that poisons are present, these immature, large, greenish, pear shaped fruit can be eaten raw or cooked, once ripe only the yellow seeds are edible.

Pigweed [Portulaca sp] and Pigface [Carpobrotus sp]
Are succulent plants found in sandy areas of the state and often near the coast, the water in their fleshy leaves is a little salty but can be purified. The ripe, red fruit of Pigface contains a sweet, jam like substance that can be eaten raw.

Quandongs [Santalum accuminatum]
Are well known for their round, wrinkled seeds the roasted kernel of which is edible and quite nutritious. The bright red, outer flesh of the ripe fruits is also edible tasting somewhat like an unripe apple. A related species, the Native Plum [Santalum lanceolatum] bears a tasty, dark purple fruit.

Saltbush
Many of these have small, juicy, yellow or red berries that are edible. Boiling the young leaves in several changes of water produces a substitute for spinach.

Water Lilies [Nymphaea sp]
Are among the water plants that have edible tubers or potato like growths at the base of the stems, they taste best when roasted in the ashes of the camp fire. The stems of the leaf and flower of the giant water lily have the texture of celery and can be eaten raw.

Boab Nut [Adansonia gregorii]
The nuts should be collected when mature but before they harden, the seeds and pith can be eaten raw or soaked in water.

Bush Tomato [Solanum diversiflorum]
These grey coloured shrubs grow to about 70 cm and have prickles on the stem and leaves, the flowers are purple. The fruit when ripe are pale yellow with black seeds surrounded by pulp. The seeds and pulp are removed and the sweet juicy flesh eaten.

Sugar Bread
The activity of insects on plants leaves a crusty white substance on gum leaves. These sweet tasting crusty particles can be eaten or dissolved in water as a refreshing drink.

Mulga Apples
These are the result of an insect that burrows under the bark of Bloodwood and Mulga trees. Inside the galls are a small amount of fluid and an edible caterpillar.

Note: Always carry out the taste test on anything that you cannot positively identify.



DIRECTION FINDING
In almost every case it is best to stay with your vehicle or aircraft as searchers will locate this first. However you may have become isolated from a walking party and find yourself lost without a compass. For this reason you will have to know how to navigate without map or compass to proceed on the escape route to safety.

Watch Method [by day]
To find north using your watch simply -
1. Stand holding your wristwatch horizontal with the figure 12 pointing at the sun
2. Bisect the angle between the hour hand and the 12 O'clock position
3. The line will indicate north [approximately]

 

Note: This method will not apply to areas north of the Tropic of Capricorn during the period of the midsummer equinox for your area.

Sun movement [by day]
The sun crosses the imaginary north/ south line [meridian] every day at noon and there are 24 hours between crossings of the meridian. During this time the earth revolves through 360º. It can therefore be said the sun travels from east to west at a speed of 15º per hour. To find north simply note the time and plot the sun from its present position backward or forward as the case may be to its noon position.

 

Shadow Stick Method [by day]
To use the shadow stick method -
1. Push a stick vertically into the ground
2. Place a stone at the end of the shadow
3. After a wait of 20 minutes place another stone at the end of the shadow
4. A line drawn from the first stone through the second stone will be a west-east line
5. Stand facing the stick with your left foot between the stones and your right foot past the stones on the line drawn and you will be looking north (in Australia, or south if you are in the Northern Hemisphere).
 

Note: In midsummer in areas north of the Tropic of Capricorn the shadow stick will be behind you.

Bushman's method
A rough estimate of south can be obtained by remembering that kangaroos rest in areas of shade during the heat of the day. As we are in the southern hemisphere the shade areas will be on the southern side of bushes [look for disturbed areas of earth].

The Southern Cross method [at night]
The Southern Cross can be used to indicate south at night by -
1. Extending an imaginary line through the long axis
2. Locating the two pointers and bisecting them at right angles with another line.
3. Where these two imaginary lines meet drop a line straight down to the horizon
4. This will indicate south [approximately]

 

NAVIGATING AT NIGHT WITHOUT A COMPASS
You will find it very easy to navigate using the stars, particularly in the more arid regions of Western Australia. Firsts establish where north or south is then draw a line on the ground indicating north - south, bisect this line with another line at 90o, this will then show east and west. You now have your compass.

Once you decide in which direction to travel, you can stand on your makeshift compass and face the direction you intend moving. Look for a bright star or better still, a group of stars that are in the required direction and move towards them.

Note: Try to select stars that are not right on the horizon as you will lose sight of these when moving around trees. Remember that stars move from east to west in the same manner as the sun and you will have to allow for this at 15o per hour. Stop periodically and check your direction by drawing your compass on the ground again.



EMERGENCY PROCEDURES
In the interests of prior planning and preparation those who live, work or travel in the outback of Western Australia should be prepared for any foreseeable emergency whether they are on foot or in a vehicle. Actions on should be planned and the knowledge and skill to carry them out should be acquired through training.

A personal first aid kit and a personal survival kit should always be carried, notifications should always be posted and safe practices must be a priority.



PROCEDURE IF LOST
If you do become lost, try to remain calm as panic will put you at a psychological disadvantage, the situation is not as hopeless as you may think.

If by any chance you have taken the wrong track and do not know where it is going to lead you, it is pointless going on any further. It would be safer to return the way you came by retracing your tracks back to a point where you can establish your location.

Case histories reveal that most people, when lost push on blindly in a state of panic, hoping that they might end up somewhere. In these cases their efforts either take them further away from civilisation or around in circles. Do not under estimate the huge vastness and great distances of our Western Australian outback.

If in a vehicle stay with or near your vehicle as it is a source of shelter and water [provided there are no chemical additives in the radiator]. Also it is easier for search parties to locate a vehicle than to locate a solitary human wandering around somewhere in the bush.

If you have to leave your vehicle temporarily to search for food or water mark your trail on the ground with sticks or stones so you can find your way back. Otherwise you may find it hard to locate your vehicle once it is out of sight. Only walk in the cool part of the day to minimise fluid loss and exposure to the sun.

If on foot once you decide you are lost consult your map and use it in conjunction with your recollection of the country you have traversed to try to identify a feature. You can consider retracing your route to your last known position, or you can make for higher ground in an attempt to fix your position.

Note: If you are operating with a pre-set escape route then you should proceed on the bearing to safety.



ELECTRONIC SAFETY AIDS
There are many aids available to the outback traveller and it is worth considering these when planning for outback travel both on foot and by vehicle.

Radio communications
For communication between vehicles a UHF citizen band radio is recommended. If travelling in more remote outback regions a HF single side band transceiver will be required. These sets will allow you to communicate with the Royal Flying Doctor Service and although expensive to buy they can be rented through local agencies. Radio schedules can be organised with the Royal Flying Doctor Service.

Position indicator beacons
There are several rescue instruments available for the purpose of signalling for assistance, these include different types of rescue beacons. Travellers in isolated or outback areas should seriously consider their use.

Satellite Navigation Systems
Global positioning systems are available in Western Australia for purchase or hire. These are a hand held system that allows you to find your exact position. They also allow you to plan routes and navigate by giving you a read out of your exact speed and heading. Even though the cost may be a factor these units are of obvious value to off road travellers, particularly when travelling through unfamiliar territory.

Note: Due to the technical nature of global positioning systems, users are advised to ensure they understand their operation fully. Map suppliers should be consulted to ensure that maps used are compatible. Not all maps [particularly older ones] use the grid system of reference used by GPS.



EMERGENCY SIGNALS
The following methods can be used to indicate your position.

Fires
A smoking fire will aid searchers, both in daylight hours and at night. Extreme care should be taken when lighting signal fires as some have got out of hand to the extent of causing major bush fires further endangering survivors and searchers.

Whistle Signals
Distress signal by lost party three signals together, regularly spaced. Searchers looking for lost party one blast at regular intervals. Acknowledgement of distress signal two blasts repeated regularly. Recall signal for search parties four blasts. Gun Shots and Torch Flashes
The same as whistle signals, guns should be discharged into soft ground, not the air.

Mirror
Your survival kit will contain some foil that can be used if you do not have a mirror or heliograph for use in bright sunlight.

 

Ground to Air Code
This is a universal code used to communicate with rescue aircraft. The figures should be approximately eight to nine metres in length and contrasting material such as rocks, logs or brush should be used. Trenches in sand can also be used to throw a shadow. Ground to air visual code for use by survivors
I/ we are unable to proceed XProceeding in this direction ­ No or negative NYes or affirmative Y If in doubt use international symbol - 'SOS'

Actions by Aircraft
The aircraft will indicate that your signals have been seen and understood by rocking from side to side in day light hours and by making green flashes with a signal lamp at night.
If ground signals have been seen by the aircraft and not understood, it will fly in complete right hand circles in daylight hours or make red flashes with a signal lamp at night

Rescue Helicopter
Never approach a helicopter from the rear, position yourself in front, in view of the pilot and wait until approached by a crew person.



FOREST OR BUSH FIRE SURVIVAL
Every year in Australia there are serious bushfires in which people are caught and sometimes die. In some cases these deaths could have been prevented if the people involved had not panicked and had a basic knowledge of bushfire survival. Here are some basic rules.

Panic
Causes energy loss and poor judgement, act calmly and do not run.

Breathing
When the smoke is dense the air closest the ground will be cool and fresh.

Heat
Radiated heat is the real danger, use anything to avoid it such as culverts, running streams, ponds, rocks or depressions.

Flame Fronts
Do not attempt to run through large flame fronts. Always move downhill from a fire as fires travel faster uphill.

Critical Periods
When you have no possible escape you should lie on the ground [bare ground, in a rut or behind a log or rocks] or bury yourself and stay put.

Clothing
When you realise that you are in danger from a bush fire cover as much exposed skin as you can with any clothing available. Do not use nylon clothing. If your clothes catch fire do not run as this feeds air to the fire, roll on the ground or use items such as blankets to smother the fire.

In a vehicle
Many tragedies have occurred because people left the safety of their vehicles and tried to flee from a fire. Your vehicle will provide much protection from radiated heat.



RIVER CROSSINGS
The question of crossing creeks and rivers is a vexed one and one that usually results in people avoiding them because of the inherent danger. It is possible in a survival situation however that you may have no option but to cross a swollen creek or river to make your way to safety.

If you are required to cross a water hazard then there are accepted methods and safety procedures that can be applied.



APPRECIATIONS
Before proceeding conduct a mental appreciation including reviewing the situation and making sure there are no alternatives and the crossing is unavoidable. Have a clear understanding of what is required by listing the factors that will help or hinder you. Consider the courses open to you and select the best course.

Considerations
If you decide you have to cross then there are several points you should consider, these include -

1. The shape of the river
2. The composition of the river bed
3. Speed of flow of the river
4. Turbulence of the river
5. Depth of water
6. Temperature of the water
7. Proposed entry and exit points
8. Capabilities of members of your group

Acceptable places to cross
There are two places where you should be safe during a crossing including shallow water [approximately thigh deep] over a gravel bed with accessible banks or a deep, slow flowing river that is not too wide.

Unacceptable places to cross
High and discoloured water with excessive flow, volume and river width.

Note: Remember you will need to consider whether to cross or not, where to cross and which method to employ.



METHODS OF CROSSING CREEKS AND RIVERS
Without aid
Used when the water is below knee deep, the crossing should be in a diagonal downstream direction with the body parallel to the water flow.

Single pole crossing
Used when the water is between the knee and groin in depth and the bottom is smooth with no obvious obstacles. The line of crossing should again be diagonal and downstream. The pole [2 m long x 5 cm diameter] should be used as a prop and you should lean in to it and walk in an arc until you have to stop and re-position the pole.

Group pole crossing
Used when the water is above groin height. This method provides mutual support and is suited to groups of 3 to 6 people. The crossing should again be diagonal and downstream in direction. The group should be parallel to the flow of water with the strongest person on the upstream end and the next strongest on the downstream end. The pole should be grasped with the upstream arm over and the downstream arm under, it is not necessary to link arms with the others in the group but you should link your arms.

Note: If conditions prove too difficult then retreat, do not try to turn around.

Swimming method
Used where the crossing is deep, the river is clear of debris and the current is not a problem. Waterproof your pack and use it as an aid by holding it in front of you with one hand and using your other hand and legs to propel yourself forward.

Points to remember
The following points are listed to assist you in any water crossing -
 

Always move side on to the current
Always take small steps and keep your eyes on the far bank
Always move diagonally across the river to lessen the effect of the current
Never fight against the current
Never hold onto submerged logs or rocks
Keep your boots on and avoid loose baggy clothing
Wear thermal clothing next to the skin in cold conditions
Waterproof your pack and contents
Loosen the shoulder straps and unfasten the waist band on your pack

 

WILDERNESS FIRST AID
First Aid is what you can do to assist an injured person at the scene using only what is available under the prevailing circumstances. You may only have your two hands, remember that first aid does not rely on equipment.

In some circumstances if there is nothing, or nothing more to be done then first aid may mean going for assistance. Remember the patient is relying on you to go carefully to avoid accident or injury to yourself.

Possibly the most important aspect of practical first aid, particularly in the bush, is clear logical thinking and the ability to improvise.

Factors
First aid is based on two factors -
· Common sense
· Knowledge and technique

Order of urgency
1. Protection of the patient from further injury.

2. Ensuring the first aider has regard for his or her safety.

3. Restoration of breathing and heart beat.

Further responsibilities
Stop bleeding, minimise pain, reassure the patient, seek further aid and if necessary transport the patient to hospital.

Making a diagnosis
Having regard to the foregoing, before you can commence rational treatment, a diagnosis must be made consisting of-

History the story of how the injury occurred Symptoms what the patient feels Signs what you can observe or find out by examination of the patient



CONDITIONS
Unconsciousness, shock, bleeding, pain and hysteria

Unconsciousness
There are many causes and these include, heart attack, drowning, electrocution, head injury, fainting and smoke inhalation. General treatment is the same -
· Remove the patient from the cause or the cause from the patient

· Examine the patient quickly

· Commence cardio pulmonary resuscitation where necessary

· Stop bleeding if necessary

· Turn the patient in to the recovery position

Shock
Shock is a fall in blood pressure that, if unchecked results in irreversible changes in the body functions at cellular level resulting in death. There is a point of no return.

The onset of shock is often delayed, such as when a person first starts bleeding. They may not be shocked, but if they go on bleeding [externally or internally] they will eventually become shocked.

Prevention is extremely important because of the ease and sublety with which a state of irreversibility can develop.

One General Cause of Shock.
The actual or relative reduction of intravascular volume where not enough blood is available for the heart to pump to vital organs, or the pressure is too low to be of any use.

Specific Causes of Shock
Bleeding, burns through loss of fluid to damaged tissues, heart attack, painful injuries, fractures, fainting and blood loss at fracture site.

Shock is also caused by disease and infection, heat stroke, fluid loss, salt loss, fatigue and vomiting.

Recognition of Shock
Cold and clammy, rapid feeble pulse, rapid shallow breathing, thirst, weakness, anxiety, restlessness, inability to speak and nausea

Treatment of Shock
Minimise fluid loss, raise the legs, protect from elements, maintain temperature, reassure, moisten lips and do not give alcohol.



FRACTURES
The key to the treatment of fractures is immobilisation. A mobile fracture is painful, can cause internal bleeding, may become compound [break through the skin] and is a major cause of shock.

Treatment of Fractures
Assess the situation and see if you can immobilise the site, reduce or re-position [only reduce a fracture if you must] and then support [axial traction if necessary.]

Method of Immobilisation
Fingers strap the broken one to the adjacent finger Legs strap legs together or splint Pelvis strap legs together Upper arm collar and cuff sling and bandage upper arm to chest Ribs leave alone Note: If the patient faints with pain do not stop, reduce and splint the fracture



FRACTURES OF THE SPINE
Fractures of the spine are associated with large forces and may be complicated by damage to the spinal cord. Therefore to avoid permanent damage, careful protective handling aimed at minimising spinal cord damage is essential.

Signs and Symptoms
These may range from severe pain to loss of sensations and lack of control over limbs.

Treatment
The aim of treatment is to prevent farther damage by immobilising the spine. If the patient should be immobilised do so by strapping the legs together, maintaining body position with improvised padding and keeping the head straight and in extension to ensure an open airway.

SPRAINS
Sprains involve the abnormal stretching or the partial tearing of the supporting ligaments of any joint, ankles are the most common in outdoor activities.

Diagnosis
Pain, swelling, tenderness and bruising but still able to use the joint or limb.

Treatment
In bush walking situations it may be better not to remove the boot if it comes above the ankle. Otherwise contrast bathing if available [alternate bathing in warm and cold water, 5 minutes at a time] or immerse in cold water for 15 minutes then bandage.

HEAD INJURY
If a patient is unconscious and he/ she has not obviously been electrocuted or drowned then you should think of head injury, remember there may be no signs. Bleeding from the nose, mouth or ears may indicate a fracture of the skull. If a patient who has been unconscious recovers and then loses consciousness again you may assume head injury.



Treatment
Treatment is very simple and general first aid principles apply. Turn into the recovery position and transport to hospital.



BURNS AND SCALDS
1st degree Superficial burns such as sunburn
2nd degree Partial thickness burns where blisters are present
3rd degree Full thickness with charred skin or white skin with a red edge

Rule of 9's
The area of burn is important once the burn has been diagnosed as 2nd degree or worse. The burnt area can be assessed as a percentage of the body surface using the following table-

Arms 9% x 2 18% Lower leg 9% x 2 18% Upper leg 9% x 2 18% Stomach 9% x 1 9% Buttocks 9% x 1 9% Chest 9% x 1 9% Back 9% x 1 9% Head 9% x 1 9% Groin 1% x 1 1% 100% Note: Tremendous fluid loss to the damaged tissues occurs with burns and in the event of a person sustaining partial thickness burns then 5% will require hospitalisation and 9% will require intra venous fluid, with full thickness burns 2.5% requires hospitalisation and 5% will require intra venous fluid.

Treatment
Cold water should be used for any burn of any thickness. Do not use butter as this will introduce bacteria and leave any blisters intact.

The use of antibiotic cream or betadine is useful because infection will convert a partial thickness burn into a full thickness burn.



BLEEDING
Blood flows through the circulatory system using arteries and veins, if there is a break or a hole in an artery or vein then bleeding will occur.

Treatment
Simply plug the hole, do not worry about whether it is arterial or venous bleeding. Remember, bleeding is bleeding. First wipe away any blood or remove the clothing so you can see where the bleeding is coming from. Next hold, press or apply pressure with a pad and bandage the source of the bleeding. Then elevate the bleeding site if practical.

If there is much bleeding the patient will develop shock quickly.

Note: Tourniquets are generally a big 'no - no' and are only to be used if you cannot stop the bleeding in any other way. Tourniquets do cause more damage and the limb may be lost altogether but use common sense, if the limb is severed use a tourniquet first as you cannot do any further damage to a limb that is not there.



PAIN
There are many causes of pain. They may be uncomfortable, incapacitating or minor injuries. [Stings, bites, splinters, blisters] remove the cause and/ or treat the injury.



HYSTERIA
Defined as irrational behaviour caused by fear or anxiety such as claustrophobia when caving, freezing when climbing a rock face or crossing a stream by way of a log bridge.



Treatment
Reassure and secure the patient from danger. This may mean immobilising him/her or roping them to a rock face or whatever. Retrieve the patient by leading or removing him/her off the offending environment to a secure position.



ASPHYXIA
Asphyxia is a state of unconsciousness induced by lack of air due to drowning, smoke inhalation, choking [foreign body in throat], foul air or gas, suffocation by sand or paralysis of respiratory muscles as in blue ringed octopus bites or cone shell stings.

Treatment
Begin cardio pulmonary resuscitation [CPR] and keep going until help arrives, remember this may be 1 or 2 hours or more.

Note: Marine stings, cone shell and blue ringed octopus victims may start breathing by themselves some considerable time after lapsing into unconsciousness.



INSECT BITES
The only fatal bites are from ticks [spiders are not insects]. Redback spiders and scorpions cause pain, not death

The other major problem is allergy. An anaphylactic [severe allergic] reaction may occur in some cases such as bee stings, wasp stings, ant bites or ingestion of certain foods such as shellfish for some people.

Treatment
Insects inject their venom below the skin and the skin is there to keep in what's in and what's out, out and it mainly does that, but things like ammonia and methylated spirits may be useful as counter irritants. In the case of bee stings the poison sac is attached to the sting and the sting being barbed will often remain in the skin. It should be removed with the blade of a knife or the edge of a piece of paper, not between the fingers as the squeezing action of the fingers will squash the venom sac and inject more venom.



SNAKE BITE
Ninety per cent of snake bites in Australia are at the ankle or below, eight per cent occur on the hands and two per cent elsewhere on the body.

Treatment
Apply a pressure bandage by bandaging straight over the bite and winding the bandage up the limb towards the body, keeping a firm pressure.

Do not bleed the site of the bite as a cut will only allow poison into the body.

Do not wipe or wash the site of the bite because the residual venom on the skin may be identifiable in the laboratory when the patient arrives at the hospital. Venom is harmless on external contact.

The pressure bandage is used because the venom is conveyed from the site of the bite in small superficial lymph vessels located just under the skin. These are easily compressed by a pressure bandage.

Avoid excessive activity [by the patient]. Carry the patient or walk him/her slowly. Reassure the patient and seek medical attention urgently.

Prevention
The best guard against snake bite is protection. If you wear above ankle boots and/or thick socks and long trousers you are less likely to be bitten by anything. Use gloves when collecting firewood, never put your hand under anything without first rolling it over with your boot. Watch where you put your feet when walking and never step over logs, always step up on them and then step down.

CUTS AND ABRASIONS
Treatment
Clean with water and apply antiseptic cream or solution as this may prevent infection later. Cover with band-aid, dressing or bandage to avoid further contamination of the wound.



BLISTERS
Treatment
Leave them intact, if you make a hole for the fluid or blood to get out you have made a hole for germs to get in. Pad away from the area causing pressure using band-aids, felt strips, a felt pad with a hole cut in it or a specially designed blister dressing

Note: Do not put the dressing directly on the blister unless it is specifically designed for this purpose as this increases pressure.



SPLINTERS
Treatment
The skin is very elastic therefore a splinter stretches the skin as it goes in and the skin then closes over it or at least grips the splinter. A small [painless] superficial cut with a scalpel at the site of entry is helpful in removing the splinter.



CARE OF FEET
Your feet get you wherever you are going, especially on bush walks, it is therefore important to take care of them. Wear suitable footwear, preferably hiking boots or shoes with a heavy sole, hygiene is important so wash feet daily and apply foot powder



CASUALTY ACTION
If you are on foot in a group and a member sustains an injury preventing him/her being carried out then a team consisting of at least two people should remain with the casualty. A second team of no less than two people should continue to the next organised check point or aid station with a written casualty report containing -
1. Designation of the group
2. The names of all group members.
3. Name of casualty
4. The nature of the problem or injury.
5. Assistance required.
6. Map details and the location of the casualty.
7. The food and water state of the group.



HYPOTHERMIA
Hypothermia is the lowering of the body core temperature.

Mild Hypothermia
Skin feels cold, looks blue or livid [mottled], the patient shivers and feels cold.

Severe Hypothermia
Skin is cold and mottled, no shivering [shivering response has failed], irrational behaviour and speech, may be uncooperative, may be unconscious. If so is near death.

Treatment
Shelter in a warm dry environment and replace wet clothing with dry clothing, leave arms and legs cold but insulate limbs with blankets to minimise further heat loss.

Re-warm critical areas [chest, neck and head] by body to body contact with two or more persons or by placing heated objects such as hot rocks [wrapped in towels to prevent burning the skin] about the areas mentioned, particularly the sides of the chest.

Breathe warm air near the patient's mouth [several people if possible] to warm the air breathed into the lungs.

If conscious re-hydrate with warm drinks [non-alcoholic]. If unconscious, transport to hospital and leave the patient cold while transporting, insulate with blankets to prevent further heat loss.

Note: A victim if cold can be resuscitated after a much longer period of technical death [when no pulse or breathing can be detected] than a patient at normal temperature.



FROST BITE
Recognition
Pain in extremities with failure of skin sensation, skin does not move freely over toes and knuckles.

Treatment
Do not thaw if likely to re-freeze, do not rub frozen parts, thaw rapidly and completely in warm water in 40º to 42ºC. Protect thawed regions, do not break any blisters and keep the whole body warm to promote circulation.



HYPERTHERMIA
Hyperthermia is Heat Stroke and may be fatal.
Factors Influencing Development
These include high air temperature, conditions of high humidity and unsuitable clothing that reduces sweat evaporation.

· Level of exercise sustained exercise causes internal heat generation. · Body build big, well muscled or fat people are more susceptible. · Level of fitness fit people have better blood flow to muscles and skin · Dehydration reduces blood volume · Age Elderly at higher risk than young. · Climate Acclimatisation to hot conditions reduces risk.

Recognition [In hot conditions]
Skin feels hot
Face flushed
Rapid pulse at rest
Dizziness
Excessive fatigue
Lethargy - no will to go on
Irrational behaviour
Cessation of sweating

Treatment
Transfer to cool shaded location and immerse in cold water, apply ice packs, water or alcohol to skin, concentrate on cooling head, neck and chest.

Re-hydrate by giving cool fluids orally and keep the patient at rest.



SALT DEPLETION
Recognition
Muscle cramps after sweating in hot conditions.

Treatment
Give oral fluids, preferably one of the commercially marketed balanced electrolyte replacements dissolved in water.

DEALING WITH DEATH
While it is an accepted fact that only a qualified Medical Practitioner can certify that a person is dead, and that treatment once started should be continued, there are occasions where the casualty is dead and a decision must be made to start or stop treatment [as the case may be].

Signs of Death
· Fixed dilated pupils, not responding to resuscitation.
· Absence of spontaneous heart beat in spite of prolonged resuscitation.
· Rigor mortis [stiffening of the body] is a late but reliable sign of death.

Note: Resuscitation should never be stopped when medical aid is imminent.

Dealing with a Dead Body
Whilst this may be an unpleasant topic it is a possibility that should be dealt with properly to avoid further stress among witnesses and address the problem in a manner to satisfy the law and to facilitate the later recovery of the body.

If on foot the group should not attempt to carry the body out with them and for purposes of morale should not split themselves up and have some of the group remain while others go for help. They should leave the body and walk out in a group.

Before doing this you should -

· Get everybody in the group to take careful notes of the circumstances surrounding the death as statements will be required for the coroner.

· Wrap the body in a tent or ground sheet and firmly secure it with rocks etc., to protect it from animals and the elements.

· Mark the spot and the trail out to allow easier location later.

· On return to civilisation report the matter to the police.

· Note any valuables on the deceased and have somebody witness them. Give them to the Police when you are able.

Effects of Death on Others-
Watch for signs of shock [witness shock] in the party. At the very least there will be depression and distress that must be handled by the group before it leads to worse manifestations of stress and shock.



NAVIGATION
Good map reading is an essential requirement for bushwalkers and travellers in the outback. Maps enable users to find their way about the country; allow recognition of features and enables the user to understand the information given on the map and the ground. They also assist in the transmission of information.



MAP READING
Map reading is the extraction of information shown on the map; the relationship of the ground to the map and the map to the ground. To make full use of a map, it is necessary to give and read grid references; to take bearings and to measure distances. The ability to use or read a map, is called "map craft".

Reliability of maps
A map is a plan of the ground. Remember however it is a plan of the ground at a certain date. If it is a long time since the map was produced or revised much may have changed. Towns grow, roads and railways are built, forests grow and are cut down. No map can be taken as being reliable except concerning the main physical features of the land. Even these may change slowly, as coast lines erode and in some places rivers may even change their courses. It is therefore very important to note the date the map was produced or revised and to judge its reliability accordingly.

Care of maps
Maps are valuable documents and the supply is never unlimited and they should be treated with care to prevent damage. Most damage to maps occurs when the users open them outdoors or in moving vehicles. There is always a slight breeze to catch them and start small tears that quickly spread. To prevent tears, maps should be folded in such a way that any part can be referred to without having to be fully opened.

Once a map is folded, leave it folded, the detail at creases is sure to deteriorate but less than if the map was constantly unfolded and folded. Protect the folded map by placing it in a plastic map case when not in use.

Marginal information
Printed around the margin of the map is the information needed when the map is being used. This is referred to as Marginal Information. The type of information and the layout may differ from map to map. On Australian maps a standard layout is adopted which gives the following information.

 

Sheet Name
This is usually shown on the top centre of the map

Map Edition
Usually located at the top right of the map

Sheet Number
Maps are commonly referred to by sheet number, name and edition

Grid Reference Block
Located at the bottom of the map and explains how to calculate a six figure grid reference

Legend Panel
Located at the bottom of the map and gives a legend of the conventional signs used

Sheet History
Located at the bottom of the map and gives production details

Index to Adjoining Sheets
Located at the bottom the map

Magnetic Variation Information
Located at the bottom of the map and gives the annual magnetic variation

Reliability Diagram
This diagram, which does not appear on all maps, indicates the reliability of the information shown on a map

Representative Fraction
A method of indicating the scale of the map. Usually located at the top left of the map.

Linear Scale
Usually located at the bottom centre of the map

 

Conventional signs or legend
The map maker tries to show the objects on the ground in the clearest possible way. These objects are not shown as they appear because they would be too small to recognise. Instead, simply symbols, referred to as conventional signs are used to indicate the objects. It is important to note that the centre base of the particular sign indicates the position of the object on the map.

Scale
The scale of a map is the relationship of the distance between two points on the map and the distance between the same two points on the ground.

Other types of maps
The information contained in this manual refers mainly to topographical maps. These maps present a complete and accurate picture of the ground by showing as much detail as their scale allows. It may be that accurate topographical maps are not available for a particular area and in this case an alternate map such as a road map, orthophotomap or air photograph will have to be used.



NAVIGATION ROUTE PLAN
This can be a pre-prepared card or data written in a note book. It is important that everybody in the group has the same information including -

 

Who the group is and the names of all group members.

Whether any members of the group have any limiting medical conditions.

Map details and scale.

Route number.

From - Waypoint/Landmark description and six figure grid reference.

To - Waypoint/Landmark description and six figure grid reference.

Distance to be covered, expressed in metres and paces.

Magnetic bearing to be walked.

Description of going, including terrain and density of vegetation.

Estimated times.

Escape routes and safety procedures.

 

GRID REFERENCES
Superimposed over the entire map are vertical and horizontal lines. These lines are known as grid lines and are numbered at each end. To assist the user when giving grid references these grid lines are defined as eastings and northings.

Eastings
The vertical grid lines that run from bottom to top [or south to north] and divide the map from west to east, are commonly known as eastings. They are numbered from west to east.

Northings
The horizontal grid lines, which run from left to right [or west to east] and divide the map from south to north, are known as northings. They are numbered from south to north. The squares that are formed where eastings and northings cross are known as grid squares.

Obtaining a 6 Figure Grid Reference
To obtain a 6 Figure Grid Reference of a position on a map with a scale of 1:25,000 or 1:50,000 use the relevant roamer scale located on the compass base plate. Grid references should always begin with the letters GR to show that they are grid references and nothing else.

 

MEASURING DISTANCES ON A MAP
To measure the distance in a straight line between two points on a map, lay the straight edge of a piece of paper against the two points and mark the distance on the paper. Next lay the paper along the linear scale and with the right hand mark against one of the primary divisions and the left hand mark against the secondary divisions to the left of the zero point on the scale. The total distance is the distance to the right of zero, plus the distance to the left of zero.

 

Figure 24 - Measuring distance [3.7 km or 3700 m]

 

PACING
When it is important that you locate a particular feature and you need to know accurately how far you have travelled it will be necessary to pace the distance. This is done by counting the number of double paces, left foot to left foot, or right foot to right foot. You will need to work out exactly how many paces you walk over one hundred metres.

Note: Most people on flat ground average 130 paces per 100 metres.



THE POINTS OF A COMPASS
North, East, South and West are the four cardinal points of the compass. There are, in all, 32 points of the compass, but only sixteen are normally used in map reading. These are the four cardinal points and twelve intermediate points.

The degree system
The points of the compass give an approximate indication of direction only, for greater accuracy the circle is divided into 360 degrees [O or 360 being the north point]. The four quadrants of the circle are each 90 degrees and therefore the East, South and West points are at 90, 180 and 270 degrees respectively. Each degree is subdivided into 60 minutes and each minute into 60 seconds. Degrees are marked o minutes ' and seconds ". When the compass is being used, the subdivisions of a degree are too small for practical use and readings to one degree are generally sufficient.

 

Figure 25 - Points of a compass

 

Note: Some organisations measure angles in mils [6,400 mils = 360°].

Bearings
The purpose of a bearing is to give an accurate indication of the direction of one point from another. A bearing is the angle, measured clockwise, that a line makes with a fixed zero line. The zero line is always taken to be north.

 

Figure 26 - Measuring bearings in degrees [A - B = 045 degrees]

 

NORTH POINTS
In map reading, reference is made to three north points and each is detailed below:

True North
The earth spins on an axis that passes through the north and south poles. The north pole is geographical north, or true north. Lines drawn from the north pole to the south pole are true north - south lines. True north is therefore the direction from any point on the earth's surface to the north pole.

Magnetic North
To say that a compass points north is only relatively true because a compass needle does not point to the north pole. It points to a place in the far north of Canada known as the magnetic pole. The direction a compass needle points is known as magnetic north.

Grid North
The grid lines on a map do not lie true north and south, except along one standard meridian; elsewhere on the map they make an angle with the true north south line. Since the grid lines are parallel and are drawn on the map it is very convenient to use them for drawing or measuring bearings. The direction of the north/south grid lines [eastings] is therefore known as grid north.



THE SILVA COMPASS
The Silva orienteering compass was developed in the 1930's and the compasses are now used widely throughout the world by armed forces and many other organisations as a general purpose compass.

 

Figure 27 - The silva compass [Type 15T]

 

Use of the compass
Because of its unique design, the Silva orienteering compass is very simple to use.

To take a grid bearing from a map
The procedure for calculating a grid bearing from a map is as follows:

 

1.Place the long edge of the compass plate along the desired bearing making sure that the direction of travel line on the compass plate points in the direction you wish to travel [if your compass has a sighting mirror at the front remember this coincides with the direction of travel line].
2.Turn the compass housing so that the meridian lines are parallel with the grid lines [eastings] on the map.
3.Read the grid bearing on the housing where the index line intersects it.
 

MAGNETIC VARIATION
The angle between the magnetic north line and the grid north line plus the annual change is known as magnetic variation or the grid-magnetic angle.

The position of the magnetic pole is not fixed, it moves slightly from year to year. As a consequence, the direction of magnetic north, and therefore the magnetic variatio
