The NFPA 704 system provides information on:

• A. General hazard and degree of severity
• B. Exact chemical composition
• C. Expiration date
• D. Manufacturer contact information

Answer: (A)

NFPA 704 is a quick-reading hazard labeling system that conveys general hazards and how severe they are. It uses four color-coded diamonds—health, flammability, reactivity, and a white area for special hazards—each with 0 to 4 to show increasing severity. This setup helps responders quickly gauge what protective actions are needed, such as PPE and ventilation, and to prioritize actions in an emergency. It does not provide the exact chemical composition, expiration date, or manufacturer contact information, which is why those details aren’t part of what this system communicates.
