Before taking response actions get a general picture of the nature
and severity of the incident including location; materials involved
and their associated hazards/risks; size, condition and possible
behavior of container, etc.
Develop a plan/course of action for preventing/reducing effects of
an incident based upon the information initially available or
subsequently obtained. To develop a plan identify problems and
establish priorities.
Factors to be considered in establishing priorities :
-
Materials and
their associated hazards/risks
-
Need for
immediate rescue
-
Protection of
affected persons
-
Responder's
safety
-
Protection of
property and environment
-
potential for
container failure
-
Availability of
resources including time
-
Weather
conditions
First priority is protecting people
Response Actions
-
Work-out
options for controlling the situation and their effectiveness
-
Decide the most
beneficial option (action or no action)
-
The actions can
be :
- Extinguishing fire
- Controlling burning or detonation
- Cooling containers
- Removing materials
- Containment to keep materials in their original container
- Using dykes to confine spilled material to the smallest
possible area
-
Removal of
persons from the affected area.
-
Isolating the
materials and hazards to the smallest possible physical area
-
Rescue affected
or endangered persons without taking any undue risks.
-
No first-aid is
given in the danger area. The rescued victim should be removed
from the danger area as quickly as possible so that both the
rescuers and victims are not subjected further to the hazards
associated with fire.
-
Cool
containers: Apply large quantity of water to the container, either
on fire (at the point of flame impingement and vapour space) or on
nearby container. (Use unmanned monitors where there is a risk to
response personnel)
-
Stress barriers
between the fire and adjoining containers might be used to prevent
container failure. They absorbs radiant heat or prevent the
container from coming into contact with the flame.
-
contain or
confine the Hazard : If leaking substance is a flammable liquid,
it can be contained by stopping the leak by closing the valve,
plugging with extreme precautions.
-
Remove all
potential ignition sources in the downwind direction first while
protecting the responders themselves. If required obtain
additional assistance from the public utility personnel from the
electric and gas companies.
-
Extinguish
Fires
- Use Proper Extinguishers perperly.
Water streams for liquids with high flash point - kerosene Foam or
DCP - for liquids with low flash point - petrol.
- Don't mix incompatible agents such as water and foam
- Don't spread water on water reactive material. Know them
beforehand
- Remove fuel supply by closing valves, plugging leakes, removing
fuel from danger area
- Remove :oxygen supply - foam/sand blanketing
- Allow the substances to burn, ensuring that it does not spread
or contaminate atmosphere.
Exposure protection
-
Protect
personnel, vehicles and other equipment during the incident.
-
Use personal
protective equipment
To be able effectively respond to fire incident
-
Follow chain of
command - receive orders for action from a single source
-
Follow
preplanned responding methods keeping the responder safety in
mind.
-
Know
functioning and use of personal protective equipment
-
Have updated
information of available support systems
-
Know different
fire fighting tasks and their safe accomplishments.
