This NFPA hazard rating system includes three color codes and five intensity levels. Each color code (blue, red, and yellow) of the hazard rating system corresponds to a hazard: health, fire, and instability (denotation or chemical change).
Codes. Standard System for the Identification of the Hazards of Materials for Emergency Response. The four divisions are typically color-coded with red on top indicating flammability, blue on the left indicating level of health hazard, yellow on the right for chemical reactivity, and white containing codes for special hazards.
Step 2: Obtain current edition copy of NFPA 704 or view on line at www.nfpa.org/704. Compare the criteria on the SDS sections as shown above with the criteria shown in Tables 5.2 (Health), 6.2 (Flammability), 7.2 (Instability) and 8.2 (Special Hazards).
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.
Knowing how and when to use an NFPA hazard diamond can prevent first responders from making deadly errors. For buildings that store hazardous materials, here are the best practices for displaying fire diamond placards: Follow local, state, or federal regulations for labeling hazardous materials.
In order to appropriately identify these hazards, each of the four labels in the NFPA Hazard classification contains listed materials from 0 to four. Zero being no hazard to four being a “severe risk.”
