Hazards can exist during production, storage, transportation, use or disposal.
If you witness a hazardous materials incident, call 911. 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 as hazardous materials can quickly be transported by water and wind. If you are in a car, close windows and shut off ventilation. To reduce the possibility of toxic vapors entering your home, seal all entry routes as efficiently as possible.
