Note: The command post can be a predetermined
location, a conveniently located building, or a
radio-equipped vehicle located in a safe area
Operational Level

Establishing and Transferring
Command at a Haz Mat Incident
• The first person on the scene or the ranking
individual of the first company on the scene
assumes command.
• The IC of a hazardous materials incident must
have IMS training and be at the hazardous
materials Operational Level.
• Command is maintained by the arriving IC until
a higher ranking or more extensively trained
responder arrives on the scene and assumes
command.
(1 of 2)

Establishing and Transferring
Command at a Haz Mat Incident
• Command can only be transferred to someone
who is on scene.
• Command can be transferred over the radio if it
cannot tank place face to face.

provide the person assuming command as
clear a picture of the situation as possible.
• There is only ONE IC.

Roles and Guidelines of
Predetermined Procedures
• Provide a standard set of actions that are the
core of every hazardous material incident plan
• Must comply with any procedures set forth in
the local emergency response plan (LERP)
• Must incorporate specific regulatory
requirements, such as those required by OSHA
• Must be written down and required to be used
Operational Level
3–22
Requesting Additional
Resources at a Haz Mat Incident
• First responders must be able to communicate
the need for assistance through their
department’s communications equipment.
• Consult departmental SOPs.
Operational Level
3–23
Using Communications
Equipment Correctly
• Radio procedures
– Use simple English (clear text)
– Transmit only essential information when sending
information and orders
– Use appropriate channels to communicate with
both the IC and the telecommunicator
– Use appropriate number of channels for the size
and complexity of the incident
• Requesting additional help — Know what types
of additional help are available, according to
(1 of 3)
the LERP
Operational Level
3–24
Using Communications
Equipment Correctly
• Emergency radio traffic
– Make the urgency clear to the telecommunicator
– Wait while the telecommunicator gives an
attention tone, advises all other units to stand by,
and advises the caller to proceed with the
emergency message
– When the emergency communication is complete,
resume normal or routine radio traffic after the
telecommunicator notifies all units to do so
(2 of 3)
Operational Level
3–25
Using Communications
Equipment Correctly
• Evacuation signals
– Broadcast a radio message ordering evacuation
– Sound audible warning devices (sirens and air
horns) on the apparatus at the incident scene for
an extended period of time
– Broadcast the message several times
(3 of 3)
Operational Level
3–26
Haz Mat Level I Incident
• Is within the capabilities of the fire or
emergency services organization or other first
responders having jurisdiction
• Is the least serious incident and the easiest to
handle
• May pose a serious threat to life or property,
but not often
• May require limited evacuation needs
Example: Small amount of gasoline or diesel fuel
spilled from an automobile
Operational Level
3–27
Haz Mat Level II Incident
• Is beyond the capabilities of the first
responders on the scene and may be beyond
the capabilities of the first response
agency/organization having jurisdiction
• Requires the services of a formal haz mat
response team
Examples: Spill or leak requiring large-scale
evacuation, any major accident, spillage, or
overflow of flammable liquids
Operational Level
3–28
Haz Mat Level III Incident
• Requires resources from state/provincial
agencies, federal agencies, and/or private
industry
• Requires unified command
• Is the most serious of all incidents
• May require a large-scale evacuation
Example: Incidents that require an evacuation
extending across jurisdictional boundaries
Operational Level
3–29
Safety Procedures to be
used on Incident Scenes
• Accountability systems/tracking resources
• Buddy system
– Is a system of organizing personnel into work
groups in such a manner that each member has a
buddy or partner, so that nobody is working alone
– Provides rapid help in the event of an emergency
• Backup personnel
– Stand by with equipment ready to provide
assistance or rescue if needed
Operational Level
3–30
The Problem-Solving
Process for Haz Mat Incidents
• Analyzing the incident/Understanding the
problem
• Planning the response/Setting strategic goals:
Action Plans
• Implementing the plan: Tactics and tasks
• Evaluating progress/Looking back
Operational Level
3–31
Analyzing a Haz Mat Incident
• Survey the scene (size-up) to detect the
presence of hazardous materials, noting
surrounding conditions to take into effect.
–
–
–
–
Wind direction
Topography
Presence of victims
Available personnel
• Conduct hazard and risk assessment.
• Identify those clues that indicate the presence
of hazardous materials.
Operational Level
3–32
(1 of 2)
Analyzing a Haz Mat Incident
• Interpret and verify those clues with emergency
response agencies, shippers, and/or other
resources in order to determine which
hazardous material is involved
• Use resources such as the ERG to estimate the
size of the endangered area and the potential
harm posed by the material
• Use information gained from initial size-up to
determine the strategy and tactics to be applied
(2 of 2)
Operational Level
3–33
Common Elements
of Haz Mat Incidents

people, the environment, or property
• Container or containers that have failed or have
the potential to fail
• Exposure or potential exposure to people, the
environment, and/or property
Operational Level

of contents in the container and the container
itself
• Mechanical — Physical application of energy
resulting in container/attachment damage
Operational Level

Ways in Which a
Container can Breach
• Disintegration — Container suffers a general
loss of integrity, such as a glass bottle
shattering or a grenade exploding
• Runaway cracking — Crack developing in a
container as a result of some type of damage,
which continues to grow rapidly
• Attachments (closures) open or break —
Attachments (such as discharge valves) fail,
open, or break off when subjected to stress
(1 of 2)
Operational Level
3–38
Ways in Which a
Container can Breach
• Puncture — Occurs as a result of mechanical
stress coming into contact with a container
• Split or tear — Failure of a welded seam on a
tank or drum or a ripped seam on a bag of
fertilizer
• Metal reduction — Caused by the corrosive
action of an acid on steel
(2 of 2)
Operational Level
3–39
Ways in Which Containers
can Release Contents

release of stored chemical energy of a
hazardous material
• Violent rupture — Immediate release of
chemical or mechanical energy caused by
runaway cracks
(1 of 2)

Ways in Which Containers
can Release Contents

hazardous material through properly operating
safety devices, damaged valves or
attachments, or holes in the container

material under atmospheric or head pressure
through holes, rips, tears, or usual
openings/attachments

The Defensive Mode of Operation
• Provides confinement of the hazard to a given
area by performing diking, damming, or
diverting actions
• Is selected when one of the following
circumstances exists:
– The facility or LERP calls for it based on a preincident evaluation of the hazards present at the
site
– Responders have the training and equipment
necessary to confine the incident to the area of
origin
Operational Level

first responders
• Includes actions to control the incident such as
plugging a leak
Operational Level

The Nonintervention
Mode of Operation
• Allows the incident to run its course on its own
• Is selected when one or more of the following
circumstances exist:
– The facility or LERP calls for it based on a preincident evaluation of the hazards present at the
site
– The situation is clearly beyond the capabilities of
responders
– Explosions are imminent
– Serious container damage threatens a massive
release

•
•
•
•
members of a team?
Have all emergency responders been adequately
briefed on the IAP and the hazards of the situation?
Can reconnaissance be made visually?
Can approach be made from
upwind/uphill/upstream?
Can contact with the material be avoided?
Can the vapor cloud, mist, dust, or smoke spread?
Is the risk worth the benefit?
Operational Level
3–57
How to Determine
if an IAP is Effective
• The IC should receive favorable progress
reports from tactical and/or task supervisors.
• The incident should begin to stabilize.
