Use a buddy system to watch for heat injury and observe the following guidelines:
• Make sure you tell someone where you are going and when you will return.
• Watch for signs of heat injury. If someone complains of tiredness or wanders away from the group, he may be a heat casualty.
• Drink water at least once an hour.
• Get in the shade when resting; do not lie directly on the ground.
• Do not take off your shirt and work during the day.
• Check the colour of your urine. A light colour means you are drinking enough water; a dark colour means you need to drink more.
Desert Hazards
There are several hazards unique to desert survival. These include insects, snakes, thorned plants and cacti, contaminated water, sunburn, eye irritation and climatic stress. Insects of almost every type abound in the desert. Humans, as a source of water and food, attract lice, mites, wasps and flies. They are extremely unpleasant and may carry diseases. Old buildings, ruins and caves are favourite habitats of spiders, scorpions, centipedes, lice and mites. These areas provide protection from the elements and also attract other wildlife. Therefore, take extra care when staying in these areas. Wear gloves at all times in the desert. Do not place your hands anywhere without first looking to see what is there. Visually inspect an area before sitting or lying down. When you get up, shake out and inspect your boots and clothing. All desert areas have snakes. They inhabit ruins, native villages, garbage dumps, caves and natural rock outcroppings that offer shade. Never go barefoot or walk through these areas without carefully inspecting them for snakes. Pay attention to where you place your feet and hands. Most snakebites result from stepping on or handling snakes. Avoid them. Once you see a snake, give it a wide berth.
