What to Do in Specific Security Situations

Hazardous Materials

Accidents or attacks involving toxic substances, industrial chemicals, or chemical, biological, or radiological (CBR) weapons can have catastrophic consequences and require large scale evacuations.  In the event of an accident involving the release of hazardous materials, understand and adhere to the following:  

Transit Facilities:

Transit Vehicles:

Trucks and trains transporting hazardous materials are commonplace on the roads and railways. Operators and drivers should be aware of the signs of a potential hazardous material release. These can include the presence of a spill or vapor cloud coming from a tank truck, rail tank car, or storage tank, or the observation of sick or injured people suffering similar symptoms from exposure.

Another way in which hazardous materials can be identified is the presence of warning labels and placards. The most common of these are ten-inch, diamond-shaped placards found on trucks and rail cars carrying hazardous materials. Regulated by the Department of Transportation, shipments of hazardous materials are divided into nine major classifications and must be placarded accordingly.

For most materials, in the event of a small leak or spill, it is recommended that the area be isolated by at least 150 feet in all directions, while trying to stay upwind. If the spill involves a trailer or rail car that is on fire, evacuation of at least a mile in all directions is usually recommended.

Most of these chemicals are perfectly safe and stable in the appropriate containers. When released and/or exposed to heat, direct flame, or incompatible materials, they can explode, catch fire, or release toxic or poisonous vapors and liquids. All of these events can lead to serious, perhaps
life-altering injuries or fatalities. Protect yourself by avoiding contact with or exposure to these substances and report the situation as soon as possible.
