-correct answer SCBA dizziness, headache, nausea, vomiting, and blurred vision, are all signs of: -correct answer heat exhaustion heat stroke is associated with -correct answer hot, dry, red skin penetration can be described as -correct answer movement of material through closures heat ________ occurs when the circulatory system begins to fail, resulting in rapid, shallow breathing and cool, clammy skin -correct answer exhaustion symptoms of heat _________ include little or not sweating; hot, dry, red skin; deep, then shallow breathing; and rapid pulse -correct answer stroke when donning SCBA with a level A suit, the self-contained breathing apparatus is: -correct answer worn inside the PPE TCFP & GFD HAZMAT AWARENESS/OPS TEST 2024 QUESTIONS AND ANSWERS permeation can be described as -correct answer occurring on a molecular level statement 1: heat exhaustion occurs because the body is unable to dissipate excessive heat and becomes overheated statement 2: heat stroke results from the failure of the temperature- regulating capacity of the body statement 3: both heat exhaustion and heat stroke are immediate life threatening conditions -correct answer statements 1 and 2 are true, statement 3 is false cracking, charring, and discoloration are examples of ________ to a chemical garment -correct answer degradation the decon of crew memebers through the use of water and soap is known as -correct answer dilution what PPE would you use for a material that had a LC50 of 5 mg/kg, had a high vapor pressure and was dermally toxic -correct answer level A TCFP & GFD HAZMAT AWARENESS/OPS TEST 2024 QUESTIONS AND ANSWERS when dealing with a radiological incident involving a leak or spill, what exposure guidelines should be used to minimize radioactive contamination? -correct answer time, distance, shielding in which type of chemical, biological, radiological, nuclear, and high yield explosives (CBRNE) call is structural FF gear and chemical protective ensemble inadequate? -correct answer explosive/mechanical the best type of PPE for thermal hazards would be -correct answer structural FF clothing the process by which a chemical enters a protective suit through openings in the garment best describes -correct answer penetration the physical destruction or decomposition of chemical protective clothing by a chemical action is called -correct answer degradation the maximum hose length allowed by NIOSH when using an airline hose respirator is _______ feet -correct answer 300 the highest level of respiratory protection is needed but lesser chemical protection is required for the skin best describes _______ protection - correct answer level b TCFP & GFD HAZMAT AWARENESS/OPS TEST 2024 QUESTIONS AND ANSWERS to protect against radiological exposures a responder should -correct answer limit the time spent in a radiation hazard area physical stresses that can affect users of specialized protective clothing include -correct answer heat stress statement 1: a phase change vest consists of a method to maintain a consistent temp of 60 degrees statement 2: ice cooled vests may be recharged by freezing the vest statement 3: ice cooled vests typically recharge faster than phase- change style vests -correct answer statements 1 and 2 are true, statement 3 is false a vest where the cooling agent is circulated throughout the garment and operates on the principle of conductive heat transfer is known as a(n) ________ vest -correct answer water cooled an air cooling system consists of small airlines providing _________ cooling of the user by blowing cool air over the body inside a suit or vest -correct answer convective TCFP & GFD HAZMAT AWARENESS/OPS TEST 2024 QUESTIONS AND ANSWERS when using air purifying respirators, which is an operational component that should be considered prior to use? -correct answer the appropriate cartridge/filter is selected prior to use what is an operational consideration when using supplied air respirators? -correct answer the proper air filtering cartridge for the expected contaminants must be selected one advantage of using level A PPE with supplied air respirators (type 3) and a vapor-protective suit is -correct answer that it permits extended operations the following advantages are indicative of what type of chemical vapor suit? 1. it offers maximum level of protection to the user 2. positive internal pressure may help to minimize minor leaks 3. if the SCBA malfunctions, the user may have some time to reach a nonhostile environment -correct answer level A fully encapsulating (type 1) heat exhaustion is associated with -correct answer cool, moist skin which is a true life-threatening emergency that requires immediate attention? -correct answer heat stroke TCFP & GFD HAZMAT AWARENESS/OPS TEST 2024 QUESTIONS AND ANSWERS lowered body core temp is called -correct answer hypothermia diking, damming, and diverting are ________ options available for ________ control -correct answer defensive; spill as a first responder trained to the operations level, which spill control tactics can be conducted? -correct answer isolate and deny entry ________ is the controlled burning of a liquid or gas to reduce or control the pressure and/or to dispose of the product -correct answer flaring another technique for reducing or controlling pressure and/or disposing of the contents is called -correct answer flaring ________ is the most commonly used method for decontaminating personnel -correct answer dilution/washing the eight step process recommended for assessing a hazmat incident includes -correct answer hazard risk evaluation
