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 3. What does TRACE-MP stand for?: Types of potential harm at Hazardous Material/WMD incidents. Thermal Radiation Asphyxiation Chemical Etiological Mechanical Psychological/ Psychogenic 4. The initial response at a HazMat incident is determined by..: The capabilities and competencies of available personnel and personal protective equipment 2 / 19 Tcfp HazMat Operations 5.

Describe the response options available for Evacuation: 1. Full scale evacuation 2. Shelter-in-place 3. Combination 7. 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) 8. 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 9. 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 3 / 19 Tcfp HazMat Operations 10. Vapor dispersion 11. Vapor suppression 12. Ventilation 13. Remote valve shutoff 10. 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 11. 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. 12. 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. 13. 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. 14. 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 15. 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. 16. 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 17. 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 4 / 19 Tcfp HazMat Operations 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 18. 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 19. 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. 20. 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 21. 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 22. 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 23. 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 24. 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 remote shutoff valves varies by device but can be as simple as flipping a switch or handle or breaking a fusible device. 5 / 19 Tcfp HazMat Operations 25. Describe the response options available for Crime Scene management and evidence preservation: a) Maintain scene control b) Limit access c) Maintain chain of custody d) Coordinate with AHJ 26. What is an AHJ...: Authority Having Jurisdiction a) Describe the response options available for Recovery and Termination: 1. Short-term recovery b) Long-term recovery c) Termination activities d) a)Debriefing e) Critique f) Post incident analysis g) Demobilization 28. What is an EPA Level A suit and when is it used...: Vapor protective, provides the highest level of respiratory and skin protection Used when chemical hazards are unknown, identified hazards are highly hazardous, when there is high potential for splash, immersion or exposure to vapors or when operations are conducted in a confined or poorly ventilated area 29. What is an EPA Level B suit and when is it used...: Liquid Splash protection, provides the highest level respiratory but lesser skin protection. Used when Atmosphere contains less than 19.5 percent oxygen or more than 23.5 percent oxygen. When there is a presence of vapors or gases indicated by a direct reading organic vapor detection instrument but vapors are not known to be harmful to skin 30. What is an EPA Level C suit and when is it used..: Level B suit with an Air Purifying Respirator 6 / 19 Tcfp HazMat Operations When the concentration and types of airborne substances are known and the criteria for using an Air Purifying Respirator are met. 31. What is an EPA Level D suit: Work uniforms, street clothing Used when no hazard are present, not acceptable for HazMat response beyond Awareness level 32. What is Decontamination...: Decontamination is performed at Hazmat incidents to remove hazardous materials from victims, PPE, Tools equipment and anything else contaminated. 33. What are the three principles of Decon...: 1. Get it off 2. Keep it off 3. Contain it ( Prevent cross contamination ) 34. What is Emergency Decon..: Emergency decontamination is the process of removing threatening contaminants from the victim or rescuers as quickly as possible without regard for the environment or property. 35. What are some instances where emergency decon is needed..: 1.Failure of protective clothing 2.Accidental contamination of first responders 3.Heat illness or other injury suffered while emergency workers were in the Hot Zone 4. When immediate medical attention is required 36. What is Technical Decon...: Technical Decon is using chemical or physical methods to throughly remove or neutralize contaminants. Technical decon is usually conducted within a formal decon line or corridor 37. What is triage...: Triage is a system used for sorting and classifying accident casualties to determine the priority for medical treatment and transportation 38. What is Isolation and Scene control..: Isolation and Scene control is one of the primary strategic goals of a Hazmat incident and one of the most important means by which you can ensure the safety of yourself and others. 39. What is an Isolation perimeter..: Sometimes called the outer perimeter, it is the boundary established to prevent access by the public and unauthorized
