NFPA 704 Diamond with 3-2-1-OXY Hazard Level Indicators

The NFPA 704 standard of the National Fire Code provides a simple system for identifying hazards associated with various materials in case of a fire, spill or other emergency. This surface-mount diamond with 3-2-1-OXY rating will help alert emergency responders to potential danger.

Please NOTE: The symbol in the white Special Hazard area of this specific diamond is not considered an "authorized symbol" by the NFPA. Before using this symbol, consult your local emergency response team regarding the use, size and placement of non-authorized NFPA symbols with your NFPA diamond. Learn more about NFPA Diamonds with our NFPA 704 Compliance Resource Bulletin (pdf).
