What is the appropriate exposure-assessment response to a chemical spill?

• A. Evacuate as needed
• B. Contain the spill
• C. Assess inhalation/skin exposure risk
• D. All of the above

Answer: (D)

When a chemical spill occurs, the goal is to protect workers by addressing how people could be exposed and by controlling the release itself. The appropriate response combines three key actions: evacuating or restricting access if there’s immediate danger or the atmosphere could become unsafe; containing the spill to prevent it from spreading, vaporizing, or contaminating surfaces; and assessing the inhalation and skin exposure risk to decide on necessary controls, decontamination, monitoring, and medical precautions. Evacuation removes people from danger, containment minimizes further exposure, and a timely exposure assessment informs what protective equipment and procedures are needed. Using all of these steps together provides a comprehensive, safety-focused approach to managing exposure during a spill.
