Explanation:

Toxic vapors are substances that can cause harm due to their chemical properties. Chemical hazards involve substances that can cause health issues through chemical reactions or toxicity. Atmospheric hazards typically 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 act through their chemical nature, they are chemical hazards.
