Emergency Preparedness Tips for Hazardous Materials

Exposure to hazardous materials

• If you have been exposed to or have been affected by a hazardous material release, call 9-1-1 immediately. 
• Stay away from the incident site to minimize the risk of contamination.
• If you are caught outside during an incident, try to stay upstream, uphill, and upwind.
• If you are in a motor vehicle, stop and find shelter in a permanent building if possible.
• If asked to evacuate your home, do so immediately.
• Listen to a local radio or television stations, or access social media for emergency alerts from authorities. Follow instructions carefully.

Know how to shelter-in-place

Sheltering is appropriate when conditions require that you seek protection in your home, place of employment or other location when there is a threat to personal safety (i.e. hazardous spills, dangerous predators).

Local authorities will advise you to stay in your home or shelter-in-place until the emergency is over.

Emergencies that require shelter-in-place include:

• A hazardous substance in the air

• A tornado

• A severe winter storm

• An earthquake

• An event that could harm the public

If the emergency is related to an environmental hazard:

• Close all windows and doors

• Tape around windows, air ducts, and vents

• Turn off fans, heating and air conditioning systems

• Close the fireplace damper

• Move to an interior room above ground level

In all other cases:

• Listen to the radio for updates and do not go outside until authorities say it is safe to do so

The length of time you are required to shelter may be short, such as during a tornado warning, or long, such as during a winter storm. It is important that you stay in shelter until local authorities say it is safe to leave.
