Establishes guidelines for the preparation of precautionary information on hazardous chemicals, as defined in the standard, that is placed on container labels intended for industrial use. It also defines criteria necessary for assessing hazards that determine which, if any, precautionary information should be placed on the label and other forms of labeling. Labeling includes container labels and other documents that contain precautionary and hazard communication information, such as product literature, technical brochures, and material safety data sheets (MSDSs). The standard must be applied in a manner that is consistent with all statutory and regulatory requirements, such as OSHA's Hazard Communication Standard; it is not the intent of the standard to substitute for these requirements, or to list each and every unique requirement.
