Which statement best describes the NFPA 704 system?

• A. It uses color-coded quadrants for health, flammability, reactivity, and special hazards.
• B. It provides only basic contact information for the manufacturer.
• C. It lists the exact chemical composition.
• D. It determines shipping routes and transport modes.

Answer: (A)

NFPA 704 identifies hazards at a glance using a diamond-shaped symbol with four color-coded sections. Each section represents a type of hazard: blue for health, red for flammability, yellow for reactivity, and white for special hazards. Numbers from 0 to 4 in the colored areas indicate how severe the hazard is, with higher numbers showing greater danger. The white section can include symbols for special hazards like oxidizers, acids, alkalis, or water reactivity. This system is not about providing contact information, exact chemical composition, or shipping routes, so the description that it uses color-coded quadrants for health, flammability, reactivity, and special hazards is the accurate one.
