Know Your Hazardous Materials: The NFPA Diamond
Many of your businesses spend each and every day dealing with hazardous materials. Some of you may be familiar with the NFPA diamond, some of you may not. The National Fire Protection Association (NFPA) uses a standard called the NFPA 704 or “fire diamond” to indicate the flammability of a substance. It also communicates information essential to emergency response teams dealing with a spill, fire or other accident involving the material.
Help make your work a safer place by educating your employees on hazardous materials classification!
Diamonds are an employer’s best friend
The NFPA diamond is broken up into four colored sections each labeled with a number from 0-4 to indicate the level of hazard. The red section serves as an indicator of flammability; blue health risk; yellow for reactivity/explosivity; and white for describing special hazards.
0 – Does not pose a health hazard, no precautions are necessary
1 – Exposure may result in irritation or minor residual injury
2 – Avoid intense or continued non-chronic exposure as it may result in incapacitation
3 –Brief exposure may cause serious temporary or residual injury
4 – Even the briefest of exposure may cause death or major injury
0 – Will not burn
1 – Requires heat to ignite; flash point exceeds 200°F
2 – Moderate heat or relatively high ambient temperature is required for ignition; flash point between 100°F and 200°F
3 – Liquid or solid that ignites at ambient temperatures; flash point between 73°F and 100°F
4 – Vaporizes at normal temperatures and readily disperses or burns; flash point below 73°F
0 – Normally stable; not reactive with water
1 – Normally stable, but may become unstable at elevated temperatures or pressure
2 – Elevated temperatures result in violent changes; may form an explosive mixture with water
3 – May detonate under severe shock or react explosively with water
4 – May detonate at normal temperature or pressure
OX – Is an oxidizer
W – Reacts with water in a dangerous way
SA – Simple asphyxiant gas (displaces the normal oxygen concentration in breathing air)
