Which statement best describes secondhand exposure and how it can be mitigated?

• A. Exposure transferred to other workers or areas; mitigated by containment, decontamination, proper workflows, and engineering controls
• B. It only affects the worker directly exposed
• C. It cannot be mitigated
• D. It is irrelevant in most workplaces

Answer: (A)

Secondhand exposure means contaminants can be carried from the source of a hazard to other people or to different areas, so exposure isn’t limited to the person performing the task. To reduce this risk, you focus on preventing spread and removing contamination: containment to keep materials from moving off the work area, decontamination to remove residues from surfaces and PPE, proper workflows that minimize cross‑contamination, and engineering controls like ventilation or enclosure that reduce airborne or spread risks. This combination addresses both the transfer mechanism and how to interrupt it, making it the best approach. The idea that exposure only affects the direct worker, or that it can’t be mitigated, or that it’s irrelevant, doesn’t fit how real-world hazards spread and how workplaces reduce risk.
