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

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. [Show Less]
