NFPA 704 Signs & Labels
- The NFPA 704 diamond system is intended to provide basic information to fire fighting, emergency and other personnel. This standard provides a readily recognized, easily understood system for identifying specific hazards and their severity using spatial, visual, and numerical methods to describe in simple terms the relative hazards of a material. These placards act as an immediate warning system for emergency service personnel, addressing health, flammability, instability, and special hazards that may be present, acute exposures that are most likely to occur as a result of fire, spill, or similar emergencies.
- NFPA 704 Hazardous Materials Identification System
Signs must be in locations approved by the authority having jurisdiction and as a minimum must be posted at the following locations:
- Two exterior walls or enclosures containing a means of access to a building or facility.
- Each access to a room or area.
- Each principal means of access to an exterior storage area.
- If there are numerous areas where the emergency personnel could enter, then, there should be numerous signs covering those areas.
- Position NFPA Diamond signs on stationary containers and above-ground tanks and at entrances to locations where hazardous materials are stored, dispensed, used or handled in quantities that require an operational permit. The purpose of these signs is to assist first responders in recognizing and identifying possible hazards, thus they should be placed as to be readily visible with respect to location and size.
The signs above represent our interpretation of material information in combination with NFPA 30 and NFPA’s Fire Protection Guide to Hazardous Materials. Without knowledge of your specific chemical, facility, or hazard, it’s impossible for us to guarantee these signs will match your situation. It is your responsibility to decide which signs are valid for your use and to comply with applicable laws and standards.
