Jewelry. Do not wear rings, watches, or other types of jewelry in the laboratory if at all possible. Such items can catch on protruding objects, serve as nice traps for spilled chemicals keeping them in contact with the body, function as nice "wires" to lead current into the body from electrical equipment resulting in shocks and/or electrocution. Generally the clean, dry skin of the body has a high resistance to electrical current; but the skin under a ring, for example, is often soft, damp, and has much lower resistance. This is especially true if you have gotten some electrolyte solution under a ring. Probably the best procedure is not to bring jewelry to the laboratory unless you have an available pocket, in order to avoid loss of the articles by misplacement or theft. In addition, jewelry can be seriously damaged by chemicals.
