Which symbols may be found in the white section of the NFPA 704?

Which symbols may be found in the white section of the NFPA 704?

• A. OX (oxidizer), W (reacts with water)
• B. F (flammable), H (health hazard)
• C. B (biological), C (corrosive)
• D. E (explosive), S (smoke)

Answer: (A)

The symbols found in the white section of the NFPA 704 system are specifically designed to indicate specific hazards associated with a material, particularly those that may need special consideration during an emergency response or in storage. The white section is devoted to indicating unusual hazards, which include: - OX, representing an oxidizer, which can intensify a fire or bring about a combustion reaction. - W, indicating that the material reacts with water, which may generate hazardous reactions, such as the release of flammable gases. These symbols provide important information to first responders, allowing them to take appropriate precautions when dealing with materials that pose specific hazards that are not covered under the traditional fire (red), health (blue), or reactivity (yellow) categories. Knowing these specific conditions can be critical for safety during an emergency.
