NFPA 704 is used to convey information about a material's:

• A. Overall hazard level and the severity in each category
• B. Exact chemical identity and supplier
• C. Expiration date and batch number
• D. Storage location and handling procedures

Answer: (D)

NFPA 704 is a hazard-rating system that uses a four-diamond symbol to quickly communicate how dangerous a material is. Each colored section—health, flammability, and reactivity—gets a number from 0 to 4, with higher numbers showing greater hazard, and the white section notes any special hazards. This gives you an overall hazard profile and the severity in each category, which is exactly what the best answer describes.

The other ideas aren’t what NFPA 704 provides: it doesn’t reveal exact chemical identity or supplier information; it doesn’t include expiration dates or batch numbers; and it doesn’t specify storage location or handling procedures—those details come from other documents like labels, the Safety Data Sheet, or facility procedures.
