HAZMAT Tech I Exam Questions and Answers 100% Pass

HAZMAT Tech I Exam Questions and Answers 100% Pass Technician level personnel are responsible for what? - Correct Answer ️️ -person who responds to hazardous materials/WMD incidents using a risk-based response process to analyze a problem involving hazardous materials/WMD, plan a response to the problem, implement the planned response, evaluate progress of the planned response and accordingly, and assist in terminating the incident. What are the requirements for Technician level personnel - Correct Answer ️️ -Must be awareness and operations certified; trained from OSHA; additional tasks are determined by the AHJ What are the goals of HAZMAT technicians? - Correct Answer ️️ -APIET Analyze HAZMAT incident; plan a response; implement the planned response; evaluate effectiveness; terminate incident What are biological hazards? - Correct Answer ️️ -Etiological; microorganisms such as virus and bacteria (or their toxins) that cause severe, disabling disease or illness (many are transferred from blood or bodily fluids What are corrosivity hazards? - Correct Answer ️️ -Destroys living tissue and damage/destroy metal; divided into acids or bases What are energy hazards? three types - Correct Answer ️️ -explosivity; reactivity; radioactivity What are explosivity hazards? - Correct Answer ️️ -Any substance or article with a great deal of potential energy that may rapidly expand and release upon activation What are reactivity hazards? - Correct Answer ️️ -Describes its relative ability to undergo a chemical reaction with itself or other materials What are radioactivity hazards? - Correct Answer ️️ -Comes in different forms, some more energetic than others; least energetic form is nonionizing; more energetic/hazardous is ionizing What are flammability hazards? - Correct Answer ️️ -Fuels susceptibility to ignition; damage life and property when they ignite, burn or explode; flammability is used to help determine incident strategies and tactics What are oxygen concentration hazards? - Correct Answer ️️ -Oxygen meters detect the percentage of oxygen in the air; 19.5%-23.5% is normal; below 19.5% is considered oxygen deficient; above 23.5% is oxygen enriched What are Thermal Hazards? Two types - Correct Answer ️️ -heat and cold What are toxicity hazards? - Correct Answer ️️ -Chemicals or biological substances that cause sickness, illness, or injury by doing damage on the molecular scale when in contact with the body are considered toxic What are important factors for detection, monitoring, and sampling? - Correct Answer ️️ -State of matter determines how to check, air is the most dangerous; to properly determine concentrations of different gasses check at different heights in a room/area, check at different grades within a building; verify monitor and sampling results when possible by using more than one sampling method and more than one technology (multiply monitor with multiple forms of technology) How to identify unknowns? - Correct Answer ️️ -Take analytical approach in attempting to ID; THESE ARE STEPS IN ORDER: monitor for radiation, flammables, oxygen, corrosives, toxics, exothermic reactions, oxidizers (and explosives) Describe developing a plan: - Correct Answer ️️ -Before beginning detection and monitoring; what is the purpose of the monitoring?; what readings should detectors anticipate-unanticipated; consider instrument failure; do not ignore results; is there more than one hazard present; what are the current weather conditions? Describe detection and monitoring hazardous solids: - Correct Answer ️️ -will usually not travel far unless blowing by wind or dispersed by explosion; responders will typically be sufficiently protected when using PPE (Level C) Describe detecting and monitoring of hazardous liquids: - Correct Answer ️️ -vaporize and expand rapidly; potential for traveling great distances; fill low level and confined spaces; before engaging in detection and monitoring actives responders at liquid releases may need to don the most protective levels of respiratory and chemical protective equipment Describe detecting and monitoring of hazardous gasses - Correct Answer ️️ -expand rapidly and fill enclosed spaces; can travel great distances from source; corrosive gasses can damage and penetrate firefighter protective clothing and SCBA; toxic gasses can kill quickly; flammable gases present an extreme fire hazard; oxidizing gases can cause explosions; inert gases can displace oxygen levels in enclosed spaces causing an asphyxiation hazard Describe considerations for selecting detection equipment: - Correct Answer ️️ - mission: rescue or product control; suspected hazards: radiation, explosives, corrosives?; portability and user friendliness; instrument weight, some are bulk or difficult to use; training; available PPE, sensitive and selectivity Describe Calibration test/Bump test - Correct Answer ️️ -ensures that sensors function appropriately for alarms and other functions; does not test the accuracy of the sensor Describe Zeroing for calibration - Correct Answer ️️ -resets the memory of an instrument to read a normal/baseline level in fresh air; some instruments will doe this automatically on powerup What sensor is not zeroed? - Correct Answer ️️ -Oxygen What must operators/technicians use for calibrating and maintaining monitoring devices? - Correct Answer ️️ -Manufacturers directions, Authority Having Jurisdiction; How do you properly determine concentrations of different gases while operating monitoring and detection devices? - Correct Answer ️️ -Check at different heights within a room/area, at different grades within a building, verify monitoring and sampling results when possible by using more than one sampling method and more than one technology. When dealing with an unknown material take an analytical approach and monitoring should include? - Correct Answer ️️ -Radiation, flammables, oxygen, corrosives, toxics, exothermic reaction, oxidizers(explosives) Describe Radiation monitoring - Correct Answer ️️ -Roentgen Equivalent in Man (rem) smaller amounts are measured in millirem
