SafetyBytes® - The NFPA 704 Hazard Identification System

The National Fire Protection Agency, or NFPA, in section 704 of the National Fire Code, specifies a diamond shaped system for identifying the hazards associated with materials. Although the system was developed primarily with the needs of fire protection agencies in mind, it is of value to anyone, including someone enrolled in a chemistry laboratory course, who needs to handle potentially hazardous material.
