What does NFPA mean?
The National Fire Protection Association

What is NFPA Classification?
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 do the NFPA colors mean?
The four bars are color coded, using the modern color bar symbols with blue indicating the level of health hazard, red for flammability, orange for a physical hazard, and white for Personal Protection. The number ratings range from 0-4.
What does NFPA stand for draw its symbol and explain significance of each part?
Definition. The National Fire Protection Association, NFPA, a private non-profit organization, is the leading authoritative source of technical background, data, and consumer advice on fire protection, problems and prevention.
When did Firecodes start?
One of the earliest sets of installation rules was issued by the New York Board of Fire Underwriters in 1881, this being subsequently adopted by the National Board in 1882. By the end of 1895, there were five distinctly recognized electrical codes in the United States.
What will the NFPA rating explanation guide tell you?
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?
The red-colored section of the NFPA Diamond is located at the top or twelve o’clock position of the symbol and denotes a material’s flammability and susceptibility to catching fire when exposed to heat. Flammability is graded on a 0 to 4 scale, and a lower rating is safer.
What does white represent on the NFPA?
The last section of the NFPA color code is white. This area is often blank, as it is intended for special hazards beyond health, flammability, or instability and does not apply to a majority of hazardous materials.
What is yellow in NFPA?
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 does W mean when displayed on the NFPA diamond?
This indicates a potential hazard using water to fight a fire involving this material. When a compound is both water-reactive and an oxidizer, the W/bar symbol should go in this quadrant and the OX warning is placed immediately below the NFPA diamond.
