Employers have the flexibility to choose the type of hazardous communication system they'd like to use in their workplace, per OSHA. Labeling systems such as the National Fire Protection Association (NFPA) 704 Hazard Rating and the Hazardous Material Systems (HMIS) are recognized and accepted, multi-color formats for identifying your hazardous chemicals and materials in the workplace. The information supplied on these labels must not be conflicting with the revised Hazard Communication Standards (HCS).

The Globally Harmonized System (GHS) of labeling is an internationally agreed-upon system, created as a way to bring consistent labeling of chemical regulations and standards of different countries, to a global level. All chemical manufacturers, importers, and distributors must ensure that each container of hazardous chemical leaving the workplace is labeled, tagged, or marked - per OSHA guidelines. Providing particular information about the hazard of your chemical is extremely important - people on the road depend on it!
