What does the NFPA 704 diamond placard indicate?

What does the NFPA 704 diamond placard indicate?

A four section multicolor “square-on-point” (diamond/placard) is used to address the health, flammability, instability and special hazards presented by short-term, acute exposures that could occur during fires, spills or other similar emergencies.

What are NFPA ratings?

NFPA 704 rating system is a standard system developed by the U.S.-based National Fire Protection Association (NFPA) for indicating the health, flammability, reactivity and special hazards for many hazardous chemicals through the use of the NFPA 704 Diamond.

How do you read NFPA ratings?

The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704. The system uses a color-coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of health hazard (blue), flammability hazard (red), and reactivity hazard (yellow).

How do you read NFPA diamonds?

Each of the diamonds is color-coded and represents a different type of hazard. Within the diamond is a number (with the exception of the white diamond). The number corresponds to the level of danger a chemical poses. The lower the number, the lower the hazard.

What do the numbers mean on the HMIS and NFPA Labels?

Numbers in the three colored sections range from 0 (least severe hazard) to 4 (most severe hazard). The fourth (white) section is left blank and is used only to denote special fire fighting measures/hazards. For additional information on NFPA, see More Resources below.

How do I read HMIS labels?

The white square shows the level of fire hazard the material poses. A “0” signifies that the material is non-flammable. A “1” indicates the material has a flash point above 200ºF, which means it must be exposed to a heat source to ignite. A “2” means the material has a flash point between 100ºF and 200ºF.

What are the 5 GHS categories?

GHS Hazard Class and Hazard Category

• Explosives.
• Flammable Gases.
• Aerosols.
• Oxidizing Gases.
• Gases Under Pressure.
• Flammable Liquids.
• Flammable Solids.
• Self-Reactive Substances.

What are the new GHS symbols?

WHMIS/GHS PICTOGRAMS

• Exploding Bomb (Explosion or reactivity hazards)
• Flame (Fire hazard)
• Flame Over Circle (Oxidizing hazards)
• Gas Cylinder (Gases under pressure)
• Corrosion (Corrosive damage to metals, skin, eyes)
• Skull & Crossbones (Can cause death or toxicity with short exposure to small amounts)
