Tcfp HazMat Operations Possible
2022 Questions and Answers
When responding to hazardous materials/WMD incidents Operations level
responders shall be able to preform the following task...
1. Analyze a HazMat incident to determine the scope of the problem
2. Plan an initial response
3. Implement a planned response
4. Evaluate the progress
Analyzing a hazardous material incident to determine the scope of the
problem involves...
1. Surveying the incident to identify containers and materials involved,
determine if wether hazardous material has been released and evaluate
the surrounding conditions
2. Collect hazard and response information from SDS,
CHEMTREC and shipping/manufacturer contracts
3. Predict the behavior of Hazardous materials and
its container 4.Estimate the potential harm through
TRACE-MP
What does TRACE-MP stand for?
Types of potential harm at Hazardous Material/WMD incidents.
Thermal
Radiation
Asphyxiati
on
Chemical
Etiological
Mechanical
Psychological/ Psychogenic
The initial response at a HazMat incident is determined by..
The capabilities and competencies of available personnel and personal
protective equipment
The response objectives at a hazardous material/WMD incident
include... 1.Evacuation
2. Search and Rescue
3. Exposure protection/ Isolating the Area
4. Defensive control techniques
5. Crime scene management and evidence preservation
6. Recovery and termination
Describe the response options available for Evacuation
1. Full scale evacuation
2. Shelter-in-place
3. Combination
Describe the response options available for Search and Rescue
1. Based on training and equipment
2. Risk-benefit analysis (risk a lot to save a lot, risk a little to save a little)
,Describe the response options available for Exposure protection/Isolating the
Area 1.Establish initial isolation zone
2. Establish protective action distance
3. Establish control zones
Describe the response options available for Defensive Control Techniques
1. Damming (Overflow or Underflow)
2. Diking
3. Retention
4. Dispersion
5. Absorption
6. Adsorption
7. Dilution
8. Dissolution
9. Diversion
10.Vapor dispersion
11.Vapor suppression
12.Ventilation
13.Remote valve
shutoff What is
Damming...
Physical method of confinement by which barriers are constructed to
prevent or reduce the quantity of liquid flowing into the environment.
Consists of constructing a barrier across a waterway to stop/control the
product flow and pick up liquid or solid contaminants
What is Underflow Damming ...
Spill control tactic used to trap floating lighter than water materials behind
the dam. Dam is constructed in a manner that allows uncontaminated water
to flow unobstructed under the dam while keeping the contaminant behind
the dam.
What is Overflow Damming...
Spill control tactic used to trap sinking heavier than water materials
behind the dam. With the product trapped, uncontaminated water is
allowed to flow unobstructed over the top of the dam.
What is Diking...
Physical method of confinement by which barriers are constructed on
ground used to control the movement of liquids, sludges, solids, or other
materials. Prevents the passage of hazmat from entering an area where it
will produce more harm.
What is retention...
Physical method of confinement by which a liquid is temporarily contained in
an area where it can be absorbed, neutralized, or picked up for proper
disposal
What is dispersion...
Chemical method of confinement by which certain chemical and biological
agents are used to disperse or break up the material involved in liquid spills
on water
may result in spreading the hazardous material over a
large area. What is absorption...
Absorption occurs when one material enters the cell structure of another
and is retianed within. Absorbents retain the properties of the materials they
, absorb and must be treated and disposed of as hazardous material
