When dealing with a hazmat leak, which of the following applies?

If you discover a cargo leak, identify the hazardous materials leaking by using shipping papers, labels or package location. Do not touch any leaking material; many people injure themselves by touching hazardous materials. Do not try to identify the material or find the source of a leak by smell. Many toxic gases destroy your sense of smell and can injure or kill you even if they do not smell. Never eat, drink or smoke around a leak or spill.
