Hazardous chemical spills can occur during transportation accidents, industrial activities or incidents involving fuel and chemical storage. Spills may release dangerous fumes, contaminate water or soil, and create fire or explosion hazards. Knowing how to protect yourself and your family can help reduce the risks during a chemical emergency.

1. MITIGATION – Reduce Your Risk

Take steps to reduce the chance of a hazardous chemical incident.

  • Store household fuels, chemicals and pesticides safely in their original containers.

  • Keep chemicals away from heat sources, drains and waterways.

  • Never mix chemicals or dispose of them improperly.

  • Be aware of nearby facilities or transportation routes where hazardous materials may be present.

2. PREPAREDNESS – Have a Plan

Knowing what to do before a chemical emergency can help protect your household.

  • Understand the difference between sheltering in place and evacuating.
