What is the range form of the NFPA hazard rating scale?

Explanation:
The NFPA hazard rating scale uses numbers from 0 to 4 in each category, where 0 means no hazard and 4 means extreme hazard. So the valid range is 0 to 4, with 0 minimal and 4 extreme. Other ranges don’t fit the standard (starting at 1 omits the no-hazard level, ending at 3 misses the most severe hazard, and 5 isn’t used).
