TCFP GFD HAZMAT AWARENESS OPS
EXAM SCRIPT WITH VERIFIED QUESTIONS
AND ANSWERS
●● Analyzing a hazardous material incident to determine the scope of
the problem involves...
Answer: 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?
Answer: 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..
Answer: The capabilities and competencies of available personnel and
personal protective equipment
●● The response objectives at a hazardous material/WMD incident
include...
Answer: 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
Answer: 1. Full scale evacuation
2. Shelter-in-place
3. Combination
●● Describe the response options available for Search and Rescue
Answer: 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
Answer: 1.Establish initial isolation zone
2.Establish protective action distance
3. Establish control zones
●● Describe the response options available for Defensive Control
Techniques
Answer: 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...
Answer: 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 ...
Answer: 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...
Answer: 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...
Answer: 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.
