Tcfp HazMat Operations
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... - 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... - 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.. - 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... - 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... - 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... - 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... - 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.
Water-miscible materials such as alcohols, esters and ketones destroy regular firefighting
foams and require alcohol-resistant foams
What is ventilation... - Ventilation is any natural or mechanical means of controlling air
movement. The same ventilation techniques used for smoke removal can be used for
hazmat incidents
What is a remote valve shutoff.. - In some situations it may be safe and acceptable for
Operations level responders to operate emergency remote shutoff valves. Activation of a
