  2. Describe the response options available for Evacuation:
  3. Full scale evacuation
  4. Shelter-in-place
  5. Combination
  6. Describe the response options available for Search and Rescue:
  7. Based on training and equipment

  12. Diking
  13. Retention
  14. Dispersion
  15. Absorption
  16. Adsorption
  17. Dilution
  1. 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
  2. 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
  3. 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.
  4. 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
  5. 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
  6. 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
  7. 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
  1. 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.
  2. 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
  3. 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
  4. 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
  5. 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. percent oxygen. When there is a presence of vapors or gases indicated by a direct
  1. What is an Isolation perimeter..: Sometimes called the outer perimeter, it is the boundary established to prevent access by the public and unauthorized persons.
  2. What are Hazard control zones..: Hazard control zones provide the scene control required at hazmat operations to protect responders from interference by unauthorized persons, help regulate movement across zones and minimize cross contamination
  3. What is the hot zone..: also called the exclusion zone, the Hot zone is potentially very dangerous. Responders need proper training and PPE to work in the hot zone.
  4. What is the warm zone..: The contamination reduction zone, decontamination stations are located here. PPE will normally be required here although in some circumstances the level of PPE may be a reduced level from the hot zone
  5. What is the cold zone...: Also called the support zone. All logistical support is carried out here. PPE is not required here because it is considered safe. The multiagency command post, staging area, donning/doffing area, backup teams, research teams, logistical support, triage and transportation areas are located here as well.

  4. What are the properties of Alpha Radiation...: Alpha particles lose energy rapidly when traveling through matter. They can be stopped by a sheet of paper or by the outer layer of human skin. Is not harmful to outside skin, but can be harmful if ingested.
  5. What are the properties of Beta Radiation..: These particles are more fast moving that alpha radiation, they can penetrate the outer layer of skin and

cause radiation damage to the body. Can travel up to 20 feet through they air, after traveling that distance they can be stopped by a single layer of clothing

  2. What are the properties of Neutron Radiation..: This is normally found in research labs and nuclear power plants. These ultra-high energy particles have mass but no electrical charge and they are even more penetrating then Gamma rays. Neutron Radiation is hazardous to health because it creates secondary radiation as it passes through human tissue.
