It is important to know how to use everything in your first-aid kit beforehand. You won't have time in the middle of an emergency to read an instruction manual. Before you go, learn about any possible hazards at your destination, such as poisonous plants, snakes and insects. Ask local officials or park rangers what special gear or clothing might be needed.
