Which color diamond of the national fire protection association label represents reactivity

If there’s an emergency, will first responders immediately know that hazardous chemicals are used or stored in your facility? Will they know if they can work safely in the area using only specialized protective equipment? Will they know if a chemical reacts with water in a dangerous way? Make sure employees are always informed with Right to Know (RTK) Labels. Critical questions like these in situations that demand snap decisions need to be answered quickly. And they are, without a word spoken, by the National Fire Protection Association (NFPA®) 704 rating system (commonly referred to as the NFPA hazard diamond or fire diamond). The NFPA 704 diamond system alerts firefighters and other emergency response personnel to the health, flammability and reactivity hazards present and special considerations needed to effectively fight a fire, spill or other dangerous situation involving hazardous chemicals. Explore the background of the NFPA diamond, its colors, numbers and legends, as well as sizing and placement as recommended by the NFPA 704 Standard.[1] Designed to deliver critical information quicklyThe NFPA diamond alerts emergency responders to the presence of hazardous materials and their potential effects, and helps them plan an appropriate emergency response. It does not identify specific chemicals in the facility or chronic, long-term health hazards as a result of them. The NFPA 704 diamond system has applications in commercial, industrial and institutional facilities that manufacture, process, use or store hazardous materials. It can also assist engineers as well as plant and safety personnel in taking inventory and evaluating the relative hazards of materials in their facility.[2] You’ve seen the fire diamond, even if you’re not a safety professionalThe NFPA diamond has been a recognizable symbol for decades, ever since its creation in 1960.[3] Anyone who works with or near hazardous and potentially dangerous chemicals or materials will most likely have seen the NFPA hazard diamond on building entrances, exterior walls or storage areas. But even when it comes to the general public, the fire diamond is widespread on semi-trucks, propane tanks, train cars and other places where potentially hazardous materials are stored or transported. The NFPA 704 system is a standard, not a codeIf you’re asking yourself “Do I need to use the fire diamond?”, the answer is: “It depends.” Because it’s a standard, the NFPA 704 system tells you how to label, not when. A local Authority Having Jurisdiction (AHJ), e.g., a fire department, determines requirements by adopting the standard and making it law. So, you should always check with your local AHJ for requirements of where and when to apply NFPA 704 labels. However, due to its beneficial and simplistic design, many facilities voluntarily place appropriate NFPA fire diamonds on buildings and locations where hazardous materials are stored or used to assist local responders in the event of an emergency and help safeguard against injury—hence its prevalence in many environments. Elements of the NFPA diamondThe NFPA 704 system is referred to as the fire diamond due to its square-on-point orientation. It’s comprised of four smaller diamonds, each distinguished by color, placement and symbol (numerical or text). The hazard numbers range from 0 (no hazard) to 4 (severe hazard). An individual technically competent and experienced in the interpretation of the hazard criteria as set forth in Chapters 5 through 8 of the NFPA 704 standard should perform a hazard evaluation.[1] These qualified individuals determine the ratings for a material by comparing data from the manufacturer‐supplied MSDS to the criteria set forth in the NFPA 704 Standard. Here’s a snapshot of the hazard degree definition associated with each diamond as laid out by the NFPA 704 Standard[1] as well as potential examples of chemicals that may be associated with each rating. Always consult a chemical’s material safety data sheet (MSDS) when determining ratings.
Location of the NFPA diamond variesWhen display of the NFPA 704 diamond is a requirement, placement and quantity will be determined by an AHJ. Generally speaking, these guidelines may adhere to the following criteria:
See Chapter 4.3 of NFPA 704 for further guidance.[1] Sizing up the NFPA diamondNFPA 704 diamond size will relate to the minimum distance at which it should be visible, which will be part of an AHJ’s requirements. See Chapter 9 of the NFPA 704 Standard for specific size requirements at certain distances.[1] References
What color diamond is National Fire Protection Association?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 are the four colors of the National Fire Protection Association?These color codes help emergency responders know about potential health, fire, and chemical instability issues. The NFPA 704 diamond sign used to display this information has four colored sections: blue, red, yellow, and white.
What do the four colors in the NFPA diamond 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.
What goes in the white diamond on the NFPA label?The white section of an NFPA Fire Diamond is used to assess a material's specific and special hazards. This section differs from the other three as it uses symbols to display specific hazards.
