What are these small openings called? - answer-Bungs Corrosives can be broken down into: - answer-Acids & bases Damage to a person's skin, resulting from exposure to sulfuric acid, is an example of what kind of health effect? - answer-Acute Dilution of material is an example of which mode of operation? - answer-Defensive Diversion of material is an example of which mode of operation? - answer-Defensive For air transportation, where would a fire fighter locate the air bill? - answer-Cockpit For hazardous materials responders, what is the most important element of personal protective equipment? - answer-Respiratory protection For which situation will structural firefighting protective clothing provide you with adequate protection? A. You will be exposed to splashes of the material. B. You will have to handle the material. C. There are high atmospheric concentrations of the material. D. None of the above. - answer-D. None of the Above How can a thermal imaging camera be useful at a hazardous materials spill? - answer-To indicate the level of material remaining in a container How can you check the compatibility of a particular chemical-protective suit with a specific material? - answer-Check the compatibility chart supplied by the manufacturer. How does a spill boom control a hazardous material? - answer-It forms a barrier to the movement of the material. How is the lid on an open-head drum fastened? - answer-By a ring and tightening hardware How large must the capacity of a liquid storage container be to qualify as a bulk storage container? - answer-More than 119 gallons How should contaminated tools and equipment be contained? - answer-In bags, barrels, or buckets If a firefighter locates Petri dishes, microscopes, and incubators during a hazardous materials response, they may be a sign that ________ are being used. - answer-biological agents If a victim is twitching, what agent would you suspect he or she has been exposed to? - answer-Nerve If fire fighters notice dead or dying animals as they approach the scene of a known or suspected terrorist incident, what should they suspect? - answer-Possible chemical release If it is necessary to isolate a hazardous materials incident, it will also be necessary to: - answer-deny entry If the load contains more than one hazard class, what type of placard might be used during transport? - answer-Dangerous In a hazardous materials situation that is dangerous and unstable and responders cannot be properly protected, what action is important and appropriate? - answer-Withdraw to a safe distance. In addition to extinguishing flammable liquid fires, what are Class B foams used for on hazardous materials incidents? - answer-To suppress vapor production of un-ignited fuels In general, a hazardous material in which state of matter will usually require the largest hot zone? - answer-Gas In hazardous materials pre-incident planning, once the agency has identified the threats in its jurisdiction, what should the agency do next? - answer-Determine how it will respond. In the ERG, the Initial Isolation and Protective Action Distances are found on pages that have __________ borders. - answer-Green
