Which hazard category causes irreversible damage to the eye?

• A. Eye Hazards
• B. Sensitizer
• C. Mutagens
• D. Acute Toxicants

Answer: (A)

Understanding this question comes down to what a hazard category implies about the kind of harm and its reversibility. The label “eye hazards” points to substances that can cause permanent, irreversible damage to the eye if exposure occurs. This includes chemical burns or tissue destruction of the cornea or other eye structures that can lead to permanent vision loss. That specific, lasting harm is what the category is signaling.

The other categories describe different kinds of risk. Sensitizers trigger immune reactions in some people after exposure, which may lead to allergic responses rather than immediate, irreversible eye injury. Mutagens affect genetic material and raise concerns like mutations and cancer risk, not necessarily direct, permanent eye damage from a single exposure. Acute toxicants cover substances that produce rapid toxic effects, which can be severe but aren’t defined by causing irreversible eye damage in particular.

So, when the question asks which hazard category causes irreversible damage to the eye, the category that fits this description is the eye hazards category.
