Which of the following best describes the initial action you should take when a chemical spill occurs?

• A. Evacuate or isolate the area, and call for assistance.
• B. Begin containment immediately to prevent spread.
• C. Alert others and assess the hazards; evacuate or isolate the area if needed; call for assistance or EH&S.
• D. Ignore and continue working

Answer: (C)

When a chemical spill happens, the immediate focus is on safety through awareness and risk assessment. Start by alerting others so people are warned and can avoid the area. Quickly assess the hazards of the spill—what chemical is involved, its toxicity, flammability, and whether it could react with other substances. This quick appraisal guides what to do next without putting you at unnecessary risk.

If the hazard is significant or you cannot control the spill safely, evacuate or isolate the area and call for assistance or EH&S. Containing a spill is not something to attempt blindly; without knowing the chemical’s properties and having the proper equipment and training, attempting containment can make things worse or expose you to harm. Ignoring the spill is never acceptable.
