A person who is repeatedly exposed to a chemical over a long period of time may develop:

• A. Acute health hazard
• B. Chronic health hazard
• C. Immediate health hazard
• D. Temporary health hazard

Answer: (B)

Repeated long-term exposure to a chemical can lead to chronic health hazards. These are illnesses that develop slowly over months or years and may persist even after exposure ends. This contrasts with acute health hazards, which show up quickly after a single or brief exposure. When exposure accumulates over time, the body may sustain damage or undergo changes that gradually become diseases, such as cancer, organ damage, or chronic respiratory problems. The focus here is on the duration and persistence of exposure, not an immediate reaction. To reduce risk, use proper PPE, implement engineering controls, conduct exposure monitoring, and minimize both the time and concentration of contact.
