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
Asphyxiation
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...
