Signs, tags, labels, and placards convey information that is intended to change behavior, give instructions, and/or convey important safety information and warnings. In this SafetyBytes® module, we’ll discuss 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.
