Question

select the choice that best completes the following statement.
toxic vapors can be categorized as:
a) chemical hazards
b) atmospheric hazards
c) impact hazards
d) compression hazards

Explanation:

Toxic vapors are substances in gaseous form that can cause harm due to their chemical properties. Chemical hazards are risks associated with chemicals, including toxic vapors. Atmospheric hazards usually refer to issues like oxygen - deficient or oxygen - enriched atmospheres. Impact hazards are related to physical impacts (e.g., falling objects). Compression hazards are about being crushed. Since toxic vapors' harmful nature is due to their chemical composition, they fit under chemical hazards.
