This lamp casts light using an open flame and one must take precautions with this flame. It is recommended to switch to an electric light source when vertical caving. A plus to carbide lamps is its use as a heat source. Within about five minutes a mildly hypothermic person can get warm by placing a carbide lamp under a garbage bag which they are inside of with only there head outside the bag. Just remember to watch the flame when it comes close to the garbage bag.
Traction is important in caving boots for grip in deep mud or slippery cave passages.
Many cavers wear hiking boots that provide strong ankle support to prevent sprains and twists. If your feet still tend to get cold, try wearing polypropolyne liners under your wool socks. Scuba socks work well at keeping you feet dry and warm in wet caves. Wear polypropolyne and other synthetics. Coveralls are nice at keeping bottom layers dry as well as providing an extra layer of clothing.
