how to reduce your chance of drowning on your camping trip
Introduction
- drowning is perhaps the most common outdoor activity lethality in Australia
- ensure your children are kept safe at all times - keep an eye on them and ensure they wear flotation devices if they cannot swim
Don't drive through flood waters
- practically every major flood event in Australia results in at least one death from someone optimistically or desperately thinking they can drive through a flooded stream safely
- unless you know the area extremely well, are experienced with driving through such conditions and have all the necessary gear to escape safely if it fails - then DON'T DO IT!
Avoid getting stranded in cars or houses in a major flood event
- in a major flood event, waters can rise very fast and catch you by surprise, especially if you are sleeping overnight
- cars can float off a flooded road and then become submerged fully in a deep channel alongside the road
Don't be stupid and get injured in the water
- diving into water that is too shallow risks fracturing your spine and quadriplegia
- falling off cliffs is never a good idea
- slipping on wet rocks and hitting your head or breaking your leg as you fall into a river
- alcohol is a major factor in falls, injuries and drownings
- don't go swimming in crocodile infested waters or in waters prone to lethal stingers
- surfing in large waves increases the risk of being dumped headfirst onto the sand or rock bottom
Don't over-estimate your swimming abilities
- those over 50 yrs old are most at risk from drowning often as their fitness and swimming abilities have declined with age without them recognising it
- alcohol is a major contributor to being overly confident near water
Don't under-estimate water currents
- this is particular problem for 4WD drivers who are crossing rivers
- it does not take much water depth to cause a vehicle to float downstream
- strength of the current is related to both current speed and depth of the water
- unseen underwater dangers are an added issue:
- deep holes
- boulders on which your vehicle may become stuck
- mud that your vehicle tyres sink into
- many areas have strong currents even in seemingly calm lakes and these are often very cold adding to the risk - if there are warning signs - heed them!
Be on the look out for dangerous currents
- at beaches, one should be knowledgeable of the notorious rips, or swim between the flags
- on rivers, potentially lethal recirculating turbulent currents can exist at the bottom of waterfalls or weirs in the right conditions
- turbulent water full of air has very reduced buoyancy making it hard to stay afloat as you are not lighter than air!
- this is compounded in a vertically recirculating current which continuously pushes you down to the bottom of the river
- not even a kayak and wearing flotation devices will save you in these conditions
Don't turn your back on the waves when on rocks
- rock fishing and exploring large rocks where the waves pound has a special risk of unexpected very large, very infrequent rogue waves which are capable of washing you off the rocks into the turbulent sea
- these waves are not from tsunamis but rather just a mathematical summation of the many competing wavelets travelling in the ocean
- avoid such rocks where these waves may be a risk - especially with an incoming high tide
Know how to get out of a rip
- if it is a patrolled beach raising your hand should signal for help if you cannot swim sideways to get out of it
- swim across the current (sideways) and you will eventually get out of the rip
