CHEMICAL SPILL MANAGEMENT GUIDELINES

A major chemical spill will usually result in the immediate evacuation of the area, if not the entire building. For example :the uncontrolled release of ammonia from a gas cylinder in an unventilated enclosed area. The volume is large and may represent a high risk to persons in the area. A minor chemical spill is one that the individual can ...
