Everyone in the rappelling areas must wear a helmet. Leather gloves are the best. Nylon gloves will melt and cloth gloves tend to wear out quickly. Brake hand must be gloved. Long Pants and long sleeved shirts provide protection.
Sturdy footwear is required.
Tie glasses with strap. Remove all jewelry and watches. Never wear loose fitting pants or shirt. Hair long enough to be put in a pony tail must be tied back. You can set a prusik knot with a foot loop, step up to relieve the tension on the system and clear the problem.
