These familiar National Fire Protection Association (NFPA) colored diamonds are commonly used with flammable materials such as solvents. For more about the NFPA system see our NFPA Information Page.

The HMIS® system of colored bars is another workplace hazard information system, but it is proprietary. Therefore, we carry a colored bar marking system that is a hybrid of the 704 system. See our Right To Know products for examples.

On this page you will find NFPA-style labels, signs, tags, posters, wallet cards and more.
