The H designation on hazard classifications refers to which type of agent?

Explanation:
The H designation marks blister (vesicant) agents. These chemicals damage skin and mucous membranes, causing painful blisters and eye injuries. They are distinct from choking agents, which irritate the respiratory tract and can cause asphyxiation, and from nerve agents, which disrupt the nervous system. An example of a blister agent is sulfur mustard, which can persist on surfaces and clothing, making prompt decontamination and proper protective gear crucial.
