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 practical practical spill control method as it typically requires so much water
that it creates a runoff problem
What is dissolution... - Correct Answer Dissolution is the process of dissolving a gas in
water. This tactic can only be used on water-soluble gases such as chlorine or
anhydrous ammonia.
What is Diversion... - Correct Answer Physical method of confinement by which barriers
are constructed on ground or placed in a waterway to intentionally control the
movement of a hazmat into an area where it will pose less harm to the community and
the environment
What is Vapor Dispersion... - Correct Answer Vapor dispersion is that action taken
todirect or influence the course of airborne hazardous material. Pressurized streams
(hoselines or unattended master streams) create turbulence which increase the rate of
mixing with air and reduces the concentration of the hazardous material
What is vapor suppression... - Correct Answer Vapor suppression is the action taken to
reduce the emission of vapors at a hazmat spill. Fire Fighting foams are effective on
spills of flammable and combustible liquids.
