Due
to the wide variety of situations Fire Department personnel may encounter in
dealing with hazardous materials, these considerations will not attempt to
provide specific guidelines on any one individual chemical or situation and are
not listed in any priority.
It
is imperative that the first arriving Fire Department unit determine what
hazardous materials is involved, and how much, prior to taking action to
stabilize the incident.
Entering
the scene to make positive identification may be a considerable risk. The danger of explosions, leaking gas and
poisoning may be great.
Action taken prior to determining the product involved may be totally wrong and may severely compound the problem.
Transportation
emergencies are often more difficult than those at fixed locations. The
materials involved may be unknown, warning signs may not be visible, or obscured
by smoke and debris, the driver may be killed or missing. D.O.T. hazardous materials marking
systems are inadequate because some hazardous materials in quantities up to
1000 lbs, do not require a placard and there may be combinations of products
involved with only a "dangerous" label showing. Sometimes only the most evident hazard is
identified, while additional hazards are not labeled.
The
following items may be significant to consider at any Hazardous Materials
incident. (Not all will be significant at any particular incident.)
Use adequate water supply.
Apply heavy streams to vapor space.
Use unmanned streams.
Use natural barriers to protect personnel.
Remove Uninvolved Materials.
Move individual containers.
Move
tank cars away from flame. Cool containers before moving.
Stop the Leak.
Close valves.
Place plug - in openings.
Place container in upright position.
Use water spray to approach leak.
Apply Diluting Spray
or Neutralizing Agent.
Dilute
water soluable liquids.
Flush
corrosives to reduce danger.
Use
spray streams to absorb vapor.
Use water with
caution on some materials.
Construct Dams, Dikes or Channels.
Direct running liquid away from exposures.
Control run off from corrosive materials.
Use sand or dirt.
Remove Ignition
Sources.
Start down wind.
Eliminate all sources of heat, spark, friction .
Call for Additional
Resources when their need is only anticipated.
The actions taken by the F.G.C. in the first few minutes of an incident
affects the outcome more than any other single factor.
