Hazardous materials can harm you in what three ways? Which option is NOT one of them?

• A. Energy release
• B. Corrosivity
• C. Toxicity
• D. Odor

Answer: (D)

Hazardous materials can harm you mainly through energy release, corrosivity, and toxicity. Energy release covers dangers like fires and explosions that can cause immediate injury or death. Corrosivity involves chemicals that burn or wear away skin, eyes, or other materials on contact. Toxicity is about substances that can harm your health through exposure, even if the harm isn’t immediate. Odor isn’t a mechanism of harm; it’s just a sensory cue and isn’t a reliable indicator of danger because many hazardous substances are odorless, and odors can be misleading. In safety practice, you rely on labels, safety data sheets, and detection instruments rather than smell to assess risk.
