What are the 4 quadrants of the hazardous materials Diamond?

The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704.

What is considered a low flash point?

Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. Combustible liquids have a flashpoint at or above 100°F.

What does low flash point mean?

Flash point is the lowest temperature at which a chemical can vaporize to form an ignitable mixture in air. A lower flash point indicates higher flammability. … At the flash point, the vapor may cease to burn when the ignition source is removed. You can often find it in the section 9 of a safety data sheet (SDS).

Are NFPA diamonds required?

NFPA 704 labels are required when another Federal, state or local regulation or code requires their use. NFPA 704 does not specify when a container, tank or facility must label with the 704 diamond.

Is the NFPA diamond still used?

Their answer: Yes, OSHA will continue to allow NFPA and/or HMIS rating systems on labels and SDSs as supplemental information. However, the rules for labeling and placement on the SDSs still apply.

What organization has setup the NFPA diamond or fire diamond signs?

NFPA diamonds are an important tool for identifying chemicals and the issues they might cause. The National Fire Protection Association established their NFPA 704 Diamond Placards to inform rescue workers if particular equipment is required and whether they need to take special precautions.

Where is NFPA on SDS?

In a 2013 interpretation letter, OSHA confirmed that SDS authors may include HMIS and NFPA ratings in Section 2 of the SDS as long as they do not contradict or cast doubt on the HCS 2012 classification. We have emphasized the last part of that statement.
