When responding to hazardous materials/WMD incidents Operations level responders shall be able to
preform the following task... - :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... - :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.
What is retention... - :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... - :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.
