Hazards are divided into two categories. Those which score high on the scale (and therefore the greatest risk) are called Category 1 hazards. Those that fall lower down the scale and pose a lesser risk are called Category 2 hazards.

Is Category 1 or 4 Worse?

For gases and some reproductive toxins, the categories are listed by names rather than numbers or letters. This ranking system where 1 = the greatest hazard and 4 = the least is the exact opposite of the NFPA and HMIS® systems, and is a serious potential point of confusion for untrained workers.
