What should all personnel immediately do if exposed to hazardous material?

• A. Inform their supervisor.
• B. Call emergency services.
• C. Put on a new pair of gloves and continue.
• D. Return to work and report later.

Answer: (A)

Informing a supervisor right away starts the proper incident response: it triggers the site’s emergency plan, secures the area, initiates decontamination and medical assessment, and ensures the exposure is documented. The supervisor can summon trained responders and activate the right procedures, so others aren’t put at risk and the response aligns with policy. If someone shows life-threatening symptoms, emergency services may be needed, but alerting the supervisor first ensures the correct chain of action is activated quickly. Continuing work or delaying reporting can spread contamination and delay care, so immediate reporting is the safest, most effective first step.
