NFPA 704 SIGNS & LABELS

This document was last updated on 04/11/2013 using NFPA 704 2012 Edition

  • 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:
    (1) Two exterior walls or enclosures containing a means of access to a building or facility
    (2) Each access to a room or area
    (3) Each principal means of access to an exterior storage area
    (4) 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.
  • Where can I find the NFPA 704 ratings for my chemicals?
    (health, flammability, instability, and special hazard information such as oxidizers, water reactivity, or simple asphyxiant gases.) The best source for the NFPA 704 ratings of a material is the Material Safety Data Sheet (MSDS), which can be obtained from the supplier of the material. The NFPA 704 ratings usually can be located in Section 16 of the MSDS. Other sources are reference material including the NFPA Fire Protection Guide on Hazardous Materials, and many other reference books and data bases on hazardous materials.

Why should the NFPA 704 Rating System be used?

  • The 704 rating system is applicable to industrial, commercial, and institutional facilities that manufacture, process, use, or store hazardous materials. Please note this standard is not applicable to transportation (DOT) or for use by the general public.
  • This standard objectives are, as stated by NFPA:
  • These signs provide an appropriate signal or alert for the protection of both public and private emergency response personnel.
  • To assist in planning for effective fire and emergency control operations, including clean-up.
  • To assist all designated personnel, engineers, plant, and safety personnel in evaluating hazards.

Understanding the NFPA 704 sign?

  • This is diamond-shaped sign with four smaller quadrants/diamonds inside. One diamond is blue, one is red, one is yellow and one is white, as shown on image. The diamond-shaped signs use the four color-coded categories to give at a glance a general idea of the hazards that personnel or observers are exposed to in any specific area.
  • The number in each inner quadrant represents the hazard rating for each of the 3 categories. Each material is assigned a rating in these three categories: health (blue), flammability (red), and instability (yellow). The white box is reserved for special hazards such as water reactivity, oxidizers or simple asphyxiant gases. The health, flammability, and instability ratings of a material vary according to its physical and chemical characteristics. The ratings are 4, 3, 2, 1, or 0, with 4, indicating severe hazard or extreme danger, to 0, indicating no required warning is necessary. Each rating is described on the image to the side.

Hazard Category: FLAMMABILITY (Red)

Because many materials will burn under one set of conditions but will not burn under others, the form or condition of the material shall be considered, along with its inherent properties

Degrees of Hazard: The degrees of flammability hazard shall be ranked according to the susceptibility of materials to burning.

  • Rating 4: Materials that rapidly or completely vaporize at atmospheric pressure and normal ambient temperature or that are readily dispersed in air and burn readily.
  • Flammable gases.
    Flammable cryogenic materials.
    Any liquid or gaseous material that is liquid while under pressure and has a flash point below 22.8°C (73°F) and a boiling point below 37.8°C (100°F) (i.e., Class IA liquids)
    Materials that ignite spontaneously when exposed to air
    Solids containing greater than 0.5 percent by weight of a flammable or combustible solvent are rated by the closed cup flash point of the solvent.

  • Rating 3: Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions. Materials in this degree produce hazardous atmospheres with air under almost all ambient temperatures or, though unaffected by ambient temperatures, are readily ignited under almost all conditions. See Annex D for more information on ranking of combustible dusts.
  • Liquids having a flash point below 22.8°C (73°F) and a boiling point at or above 37.8°C (100°F) and those liquids having a flash point at or above 22.8°C (73°F) and below 37.8°C (100°F) (i.e., Class IB and Class IC liquids)
    Finely divided solids, typically less than 75 micrometers (μm) (200 mesh), that present an elevated risk of forming an ignitible dust cloud, such as finely divided sulfur, National Electrical Code Group E dusts (e.g., aluminum, zirconium, and titanium), and bis-phenol A.
    Materials that burn with extreme rapidity, usually by reason of self-contained oxygen (e.g., dry nitrocellulose and many organic peroxides)
    Solids containing greater than 0.5 percent by weight of a flammable or combustible solvent are rated by the closed cup flash point of the solvent.

  • Rating 2: Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Under normal conditions, these materials would not form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating they could release vapor in sufficient quantities to produce hazardous atmospheres with air. Materials in this degree also include finely divided suspended solids that do not require heating before ignition can occur. See Annex D for more information on ranking of combustible dusts.
  • Liquids having a flash point at or above 37.8°C (100°F) and below 93.4°C (200°F) (i.e., Class II and Class IIIA liquids)

    Solids containing greater than 0.5 percent by weight of a flammable or combustible solvent are rated by the closed cup flash point of the solvent.

  • Rating 1: Materials that must be preheated before ignition can occur. Materials in this degree require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Materials in this degree also include finely divided suspended solids that do not require heating before ignition can occur. See Annex D for more information on ranking of combustible dusts.
  • Rating 0: Materials that will not burn under typical fire conditions, including intrinsically noncombustible materials such as concrete, stone, and sand.
  • Materials that will not burn in air when exposed to a temperature of 816°C (1500°F) for a period of 5 minutes in accordance with ASTM D 6668, Standard Test Method for the Discrimination Between Flammability Ratings of F = 0 and F = 1

Hazard Category: SPECIAL HAZARDS (White)

Only W with a line thru (water reactivity), OX (oxidizers) and <hr /> (simple asphyxiant gases) are officially part of the NFPA 704 2012 standard.

8.2 Symbols. Special hazards shall be represented by a spatial arrangement denoted by symbols always at the six o'clock position.

8.2.1* Materials that react violently or explosively with water (i.e., water reactivity rating 2 or 3) shall be identified by the letter "W" with a horizontal line through the center ( W ).

8.2.2* Materials that possess oxidizing properties shall be identified by the letters "OX"

8.2.3* For chemicals requiring both "special hazard" symbols (i.e., W and OX), the W shall be displayed inside the special hazards quadrant, and the OX shall be displayed directly below or adjacent to the special hazards quadrant.

8.2.4* Materials that are simple asphyxiant gases shall be permitted to be identified with the letters "SA" and shall be limited to the following gases: nitrogen, helium, neon, argon, krypton, and xenon.

Official Recognized NFPA 704 Symbols

  • W (with line accross): Materials that react violently or explosively with water.
  • OX: Materials that possess oxidizing properties.

Optional Symbol

  • SA: Materials that are simple asphyxiant gases (includes nitrogen, helium, neon, argon, krypton, and xenon).

Non-Standard Symbols

User-defined symbols or markings below must be placed outside the NFPA "diamond". Appropriate training and communication addressing these other markings are essential. Other special hazard symbols (beyond OX and W ) should not be considered to be part of the NFPA 704 hazard rating system. In many cases, the hazards represented by these symbols are already considered in the health, flammability, or instability rating categories. In addition, because these additional symbols are not defined by the standard, emergency responders might not recognize their significance.

  • COR: Materials that will not burn.
  • ACID and ALK (Alkali) to be more specific.
  • BIO: Biological Hazard.
  • POI: Poisonous Material (e.g. strychnime)
  • CYL or CRYO: Cryogenic Material (e.g. liquid nitrogen)
  • Radioactive trefoil: Radioactive materials. (e.g. plutonium, uranium)
  • The field may also be left blank if no special hazards are present.
