What information does the NFPA 704 diamond convey and how is it used in the workplace?

• A. The container color only
• B. Health, flammability, reactivity, and special hazards with colored bars or numbers
• C. Price per unit
• D. Ingredient list

Answer: (B)

The NFPA 704 diamond is a quick-read hazard rating that communicates the level of danger a chemical presents in four areas: health, flammability, reactivity, and any special hazards. Each area uses a color and a number (0 to 4) to convey severity. Blue stands for health, red for flammability, yellow for reactivity, and white for special hazards (such as oxidizers or water reactivity). A higher number means greater danger, with 0 indicating no hazard and 4 indicating severe hazard. The white section may include symbols like OX for oxidizers or a W with a line through it for water-reactive substances. In the workplace, this diamond is placed on containers and in storage areas so workers and emergency responders can quickly assess risk, decide on appropriate PPE and handling precautions, determine proper storage separation, and guide spill or emergency response. It’s a concise hazard snapshot, not a label of price or ingredients or container color. For full details, workers still refer to the safety data sheet (SDS) or chemical label for comprehensive information.
