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 each of the four colored sections in the NFPA label indicate?

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. The Health section conveys the health hazards of the material.

What does Flammability 1 mean on MSDS?

1. SLIGHT HAZARD This material must be preheated before ignition will occur. Flammable liquids in this category will have flash points (the lowest temperature at which ignition will occur) at or above 200º F (NFPA Class IIIB).

What does each section of the NFPA diamond represent?

In accordance with National Fire Code (NFC) section 704, the NFPA Diamond is designed as a color-coded array of four numbers or letters arranged in a diamond shape. … Each section color corresponds to a type of danger, and each number or letter denotes the scale of the danger.

Which number on an NFPA 704 label indicates the most severe hazard?

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.

What do the colors mean in the ERG?

What does a yellow colored dot label indicate?

All of the companies use the color red for flammability, blue for health, and yellow for reactivity as taken from the National Fire Protection Association (NFPA) color code system.

What does the color white within a diamond mean?

Fire diamonds located on tanks and buildings indicate the level of chemical hazard located there. The four colors are blue, red, yellow, and white. … The white indicates special precautions, usually used for oxy, or oxidizing agent.

What does white represent on the NFPA diamond?

The white diamond, appearing at the bottom of the label, conveys Special Hazard information. This information is conveyed by use of symbols that represent the special hazard.

What does the blue diamond represent on an NFPA container label?

The blue diamond, appearing on the left side of the label, conveys Health Hazard information for persons exposed to the material.

How do you read a diamond label?

1. Top diamond is red to tell you about flammability.
2. Left diamond – blue, to indicate health hazards.
3. Right diamond – yellow, on chemical reactivity.
4. Bottom diamond – white, telegraphs special information on radioactivity, acidity, poisons or other things.

Why does proper interpretation of the NFPA diamond important?

The blue NFPA hazard diamond is used to signify health. It will help you determine how hazardous the material is to people. There are five ratings that show you how dangerous the material can become. represent chemicals that are harmful to people when used incorrectly but are often not deadly.

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 flash point of a substance with an NFPA rating of 3?

Combustible liquids are classified as Class II and Class III, which are further sub-classified, based upon additional criteria that affect fire risk, as Class IIIA and Class IIIB – these liquids have flash points of 100 ºF (37.8 ºC) or more.

What does a flammability rating of 2 mean?

Level 2 – Materials that easily undergo a violent reaction, but do not explosively decompose. ◆ Level 1 – Materials that are normally stable, but become explosive at elevated temperatures and pressure. ◆ Level 0 – Materials that are stable even under exposure to fire.

When a red NFPA Square has a 4 on it means the flashpoint for flammability is?

Red: Flammability Hazard 4 – Materials with a flashpoint below 73°F and a boiling point above 100°F – Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily. Example: propane gas.

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.

What does the color green on a placard or label mean?

Green placards indicate the material is non-flammable; Yellow placards indicate the material is an oxidizer; Blue placards indicate the material is dangerous when wet; … Orange placards indicate the material is explosive; White placards with black stripes indicate miscellaneous hazardous materials.

What is a limited quantity label?

The limited quantity is the maximum quantity per inner packaging or article for transporting dangerous goods as limited quantities. … The excepted quantity is the maximum quantity per inner and outer packaging for transporting dangerous goods as excepted quantities.
