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).
What is the NFPA diamond called?
NFPA 704, also known as a fire diamond, is a diamond-shaped sign or picture that tells people about the hazards of a chemical compound. It was designed in 1960 by the National Fire Protection Association, as a way of quickly telling firefighters and other emergency workers what kind of dangers might be nearby.
What is the range for the NFPA diamond?
NATIONAL FIRE PROTECTION ASSOCIATION (NFPA) RATING SYSTEM
Chemical substances are rated for degree of HEALTH RISK (blue diamond), FLAMMABILITY (red diamond), REACTIVITY (yellow diamond), on a scale of 0 to 4.
What hazard is represented by the white diamond?
White Diamond = Special Hazard Info
The white diamond, appearing at the bottom of the label conveys Special Hazard information. This information is conveyed by use of symbols which represent the special hazard.
Is the NFPA diamond still used?
“Employers may continue to use rating systems such as National Fire Protection Association (NFPA) diamonds or HMIS requirements for workplace labels as long as they are consistent with the requirements of the Hazard Communication Standard and the employees have immediate access to the specific hazard information as
What does the color white indicate on an NFPA 704 marker?
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.
What does the R stand for in ERG?
Response. Emergency Response Guide. What does the R stand for in ERG? Safety of responders.
Are NFPA diamonds required?
Building facility placards must be 15 inches by 15 inches, with each category diamond 7.5 inches by 7.5 inches. Each category diamond on the placard must have the proper background color. The numbers must be 6.0 inches in height with a 0.75-inch stroke, and the number must be centered within its diamond.
How is NFPA 704 rating calculated?
The picture below shows NFPA rating criteria and a typical NFPA 704 label. Different colors represent different types of hazards. A number rating system of 0-4 is provided to rate each of the four hazards and is placed on a placard. 0 represents the least hazardous while 4 represent the most hazardous.
What is the most severe NFPA hazard rating?
Number System: NFPA Rating and OSHA’s Classification System 0-4 0-least hazardous 4-most hazardous 1-4 1-most severe hazard 4-least severe hazard • The Hazard category numbers are NOT required to be on labels but are required on SDSs in Section 2.
Does GHS use pictograms?
While the GHS uses a total of nine pictograms, OSHA will only enforce the use of eight. The environmental pictogram is not mandatory but may be used to provide additional information.
What do each of the NFPA 704 fire diamond flammability ratings 0-4 mean?
The blue, red, and yellow fields (health, flammability, and reactivity) all use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger.
Are HMIS and NFPA the same?
HMIS was developed by the National Paint and Coatings Association (NPCA). NFPA is a fire protection hazard warning system designed to provide rapid, clear information to emergency responders on materials under conditions of fire, chemical spill, or other emergency situations.
