Tcfp HazMat Operations Complete
Study set with Questions and 100%
correct Answers
When responding to hazardous materials/WMD incidents Operations level responders shall be
able to preform the following task... - correct answer- ✅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... -
correct 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? - correct 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.. - correct answer- ✅The capabilities
and competencies of available personnel and personal protective equipment
The response objectives at a hazardous material/WMD incident include... - correct 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 - correct answer- ✅1. Full scale
evacuation
2. Shelter-in-place
3. Combination
Describe the response options available for Search and Rescue - correct 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 - correct
answer- ✅1.Establish initial isolation zone
2.Establish protective action distance
, 3. Establish control zones
Describe the response options available for Defensive Control Techniques - correct 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... - correct 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 ... - correct 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... - correct 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... - correct 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.
What is retention... - correct answer- ✅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... - correct answer- ✅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... - correct answer- ✅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
What is adsorption... - correct answer- ✅Adsorption is different from absorption in that the
molecules of the hazardous materials physically adhere to the adsorbent material Adsorbents
do not swell like absorbents
Produces heat and can cause spontaneous combustion must be disposed of properly.
Examples: activated charcoal, silica, aluminum gel, fuller's eath, POROUS clay and other clays
What is dilution.. - correct answer- ✅Dilution involves applying water to a water soluble material
in order to reduce the hazard. It is a useful way to preform decontamination but it is not a
