The National Fire Protection Association (NFPA), under Section 704 of the National Fire Code, defines the system for identifying hazards associated with chemical materials.

The NFPA 704 Diamond - also known as the Fire Diamond —  is a color-coded symbol that provides quick, visual hazard information to emergency responders, safety officers, and anyone handling hazardous substances. It uses a four-color, diamond-shaped symbol to communicate chemical hazards during emergencies such as fires, spills, or explosions.

Each quadrant of the fire diamond provides critical safety information:

• • Blue – Health Hazard
• • Red – Flammability
• • Yellow – Instability (Reactivity)
• • White – Special Hazards

The blue, red, and yellow sections display a numerical rating from 0 to 4:

• • 4 = Severe hazard / extreme danger
• • 0 = Minimal hazard

The white section is for special hazard symbols such as:

• • OX (Oxidizer)
• • W (Water reactive)
• • SA (Simple asphyxiant gas)

This system provides a clear, visual warning to first responders and safety personnel to help them make fast, informed decisions.

The best source for NFPA hazard ratings is the Material Safety Data Sheet (MSDS/SDS) provided by your chemical supplier. NFPA 704 ratings are typically found in Section 16 of the MSDS. Additional references include:

• • NFPA Fire Protection Guide on Hazardous Materials
• • NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergency Response
• • Hazardous materials databases and safety reference manuals

Always verify ratings with up-to-date documentation before creating signage.

Do NOT use the GHS hazard category numbers shown in section 2 of HazCom-compliant SDSs as NFPA 704 Hazard Ratings. GHS numbers are not the same as NFPA hazard ratings.  (For GHS, 1 is most hazardous - the opposite of NFPA 704.)

NFPA Diamond Signs and Labels are typically placed on building exteriors, doors, and storage tanks, ensuring they are clearly visible during a fire, chemical spill, or other emergency. According to NFPA 704 guidance, signs must be placed in locations approved by the authority having jurisdiction (AHJ). Review Section 4.3 of NFPA 704 for location guidance. At a minimum, they should be posted:

• • On two exterior walls with access to a building or facility
• • At each access point to a hazardous room or area
• • At principal entrances to exterior storage areas
• • On stationary containers and above-ground tanks
• • At entrances where hazardous materials are stored, used, or dispensed in quantities requiring a permit

If emergency personnel could enter from multiple points, multiple signs should be installed. Proper placement ensures the sign is readily visible and appropriately sized for the viewing distance.
 

When are NFPA Diamonds Required?

NFPA 704 labels are required whenever another regulation or code (Federal, state or local) requires their use. OSHA and fire codes widely reference NFPA 704. The NFPA 704 does not specify WHEN labels must be used -- it tells HOW to label when another agency requires NFPA labeling.

NFPA codes that require 704 labels for specific occupancies, storage, and hazardous materials, include:

• • NFPA 1 - Fire Code
• • NFPA 30 - Flammable and Combustible Liquids Code
• • NFPA 45 - Standard on Fire Protection for Laboratories Using Chemicals
• • NFPA 55 - Compressed Gases and Cryogenic Fluids Codes
• • NFPA 400 - Hazardous Materials Code

Some facilities install NFPA 704 placards regardless of actual requirements to provide additional information about material hazards on their sites.

Can I Find Hazard Ratings in the NFPA Standard?

No. NFPA 704 does not include hazard ratings for specific chemicals. Hazard evaluations should be performed by persons who are technically competent and experienced in the interpretation of hazard criteria identified in the Standard. A qualified person can determine the ratings for a material by comparing a manufacturer-supplied material safety data sheet (MSDS) to the NFPA criteria. Some MSDSs include NFPA 704 Diamond information or rating numbers.

How Do I Determine NFPA Hazard Ratings?

Ratings must be determined by a qualified safety professional. Compare Material Safety Data Sheet (MSDS) information against NFPA 704 criteria. The NFPA says the following sections of a MSDS should be reviewed when determining hazard ratings:

• • Health – Sections 2, 4, 8, 9, 11
• • Flammability – Sections 2, 3, 9
• • Instability – Sections 5, 7, 10
• • Special Hazards – Sections 5, 9, 10, 11

NOTE: Do NOT use the GHS hazard category numbers shown in section 2 of HazCom-compliant MSDSs as NFPA 704 Hazard Ratings. GHS numbers are not the same as NFPA hazard ratings.  (For GHS, 1 is most hazardous - the opposite of NFPA 704.)

What Size NFPA 704 Label is Required?

Sign or placard size depends on the distance at which the hazard ratings must be legible. Chapter 9 of NFPA 704 gives guidance on the size of the hazard ratings relative to the size of the placard. It also gives the minimum size of ratings based on the distance at which the ratings are legible. Your local jurisdiction may have minimum size requirements.
