Lab coats : The lab coat should fit well and should be buttoned up correctly at all times. Cotton lab coats are more suitable than those made from nylon as the former could absorb more liquid and offer more protection against spilled chemicals. An added advantage is that the cotton coats do not generate sparks by static electricity that might ignite highly flammable organic solvents. Nylon also melts when heated and can stick to the flesh. It also dissolves in some organic solvents.
