HazCom - Short for "Hazard Communication," the name of the regulation first made final in 1983 and codified at 29 CFR 1910.1200.  Also referred to as the "Employee Right-To-Know Law," but not to be confused with the Community Right-To-Know Law, which is a whole different arena (and an EPA, rather than OSHA, regulation).

HMIS - Hazardous Materials Information System.   A method of labeling chemical containers with numbers and symbols which provides quick identification of hazards (once you know the meanings of the numbering and symbol system).  Very useful to firefighters and emergency responders in particular.   Another, similar uniform labeling system is NFPA.

Legend (for acronyms, abbreviations...) - In labs only, it is acceptable to use acronyms or abbreviations (or names, e.g. "Bouin's solution") if and only if a legend ("key," "guide...") is prominently placed and easily found (because it's clearly identified) by non-lab personnel such as fire-fighters or emergency responders. The idea is to make the chemical identity and hazards of all chemicals and items resembling chemicals available to ANYONE who needs them.
