What is the NFPA 704 rating?

What is the NFPA 704 rating?

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.

What 4 hazards are classified on the NFPA 704 Diamond?

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 are NFPA ratings?

NFPA Rating (optional) – The National Fire Protection Association (NFPA) has developed a system for indicating the health, flammability and reactivity hazards of chemicals.

Where is NFPA rating 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.

What does 4 represent in the NFPA 704 Diamond?

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. Acute hazards are more typical for emergency response applications.

What is NFPA 704 designed?

The NFPA 704 standard is widely used and recognized by fire and emergency responders and safety personnel for identifying the hazards of short term/acute exposure to materials under conditions of fire, spill, or similar emergencies.

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.

What does the number 4 in the Red Diamond represent?

A four in the red indicates an extremely high ability to ignite and combust. The Yellow concerns Reactivity, or the chemical’s ability to react with other chemicals in the environment. The white indicates special precautions, usually used for oxy, or oxidizing agent.

What does Level 4 flammability hazards indicate?

Risk level 4: Very flammable gases or very volatile flammable liquids. Shut off flow and keep cooling water streams on exposed tanks or containers. Risk level 3: Materials that can be ignited under almost all normal temperature conditions. Water may be ineffective because of the low flash point.

What does NFPA 704 apply to?

Who is the National Fire Protection Association NFPA 704?

“NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response” is a standard maintained by the U.S.-based National Fire Protection Association.

Where can I find the NFPA 704 diamond symbol?

Though it is not required, some SDSs include the NFPA 704 diamond symbol with ratings, and some SDS provide the NFPA 704 rating numbers within text of the SDS. (See Question 7) While the criteria are located in NFPA 704, the actual ratings for specific chemicals are not included in the document.

What are the catalog numbers for sodium pyrophosphate?

Section 1 – Chemical Product and Company Identification MSDS Name:Sodium pyrophosphate decahydrate Catalog Numbers:AC205970000, AC205970050, AC205970250, AC205975000, S390-10, S390-3, S390-500 Synonyms:TSPP.

The white “special notice” area can contain several symbols. The following symbols are defined by the NFPA 704 standard. Oxidizer, allows chemicals to burn without an air supply (e.g. potassium perchlorate, ammonium nitrate, hydrogen peroxide ).

How are health flammability and reactivity rated in NFPA 704?

Each of health, flammability and reactivity is rated on a scale from 0 (no hazard) to 4 (severe hazard). The latest version of NFPA 704 sections 5, 6, 7 and 8 for the specifications of each classification are listed below.

What’s the difference between Osha and NFPA 704?

The NFPA 704 standard and OSHA’s Hazard Communication standard were developed for different purposes. Now that OSHA has adopted GHS both systems involve numbers leading to many questions about how the two numbers systems relate.

What are the colors of the NFPA scale?

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. Each of health, flammability and reactivity is rated on a scale from 0 (minimal hazard) to 4 (severe hazard).
