Under what circumstances must you inform an employee of exposure to a toxic substance?

• A. In All Cases
• B. Only If Symptoms Occur
• C. Only If Exposure Exceeds Threshold
• D. Never

Answer: (A)

The idea being tested is the right-to-know requirement: employers must inform employees about hazards from toxic substances in the workplace. This obligation exists whenever there is any potential or actual exposure to a hazardous chemical, not only when someone shows symptoms or when exposure exceeds a regulatory limit. Providing this information helps workers understand the risks, use the proper protective equipment, follow safe procedures, and seek help if exposure occurs. Labels, safety data sheets, and training are part of meeting this duty, so employees are informed before and during tasks that involve hazardous substances. Therefore, you inform in all cases where exposure could occur, making informing employees the standard practice regardless of symptoms or threshold levels.
