responsible for securing facilities, services, and equipment when the safety officer notices a critical emergency condition at an incident, they should intervene in the unsafe action one the safety officer arrives on the scene, the IC should have the SO review the incident action plan when determining the location of the command post, it is vital that it is in a safe area level III incidents often require the technical expertise of to be brought in for appropriate handling of such an incident a specialist the person who advises the IC of existing or potentially unsafe conditions, monitoring conditions of personnel, and compliance with standard operating procedures is the safety officer a level II incident is beyond the normal capabilities of the first responder having jurisdiction and may require a response from a hazardous material response team at a hazardous materials emergency, the operations section serves the task of: controlling the tactical portion of the incident what would show that the correct actions were taken at a flammable gas leak? lower readings on the monitors when a fire involves the cargo of a truck transporting explosives, the responders should immediately evacuate the area if the SO notices an unsafe activity at an emergency, the SO should stop the activity immedately at a hazmat incident, the assistant safety officer directly reports to the safety officer at a hazmat incident, which function area is responsible for developing a special technical group to the basic ICS operations what is unique about hazmat IMS? there are typically 2 safety officers assigned the incident command post at a hazmat incident: should relay their location to the dispatcher and responding personnel which are safety guidelines for the use of vapor protective clothing? suits significantly impair mobility when considering personal protection, remember that the most vulnerable route of exposure for an emergency responder is the respiratory system work uniforms that provide minimal protection best defines EPA protection level D the highest level of respiratory protection is needed but lesser chemical protection is required for the skin best defines EPA protection Level B the type of breathing system that cannot be utilized in an oxygen deficient atmosphere is a(n) air-purification respirator SCBA and supplied air respirators, are two types of atmosphere supplied devices exposure to materials may cause freeze burns and frostbite cryogenic the most critical parameter when selecting the appropriate level of chemical protective equipment is chemical compatibility the highest level of protection, based on EPA guidelines, from hazardous chemicals provided by chemical protective clothing is level A the minimum level of respiratory protection for employees engaged in emergency response and exposed to an unknown hazardous substance is a(n)? positive pressure SCBA which is a physical limitation of personnel working in a positive pressure SCBA? physical condition this suit is used where splashed may occur, but where respiratory hazards are minimal level C statement 1: when decontamination and doffing of PPE occurs in a cold environment, the body can cool rapidly statement 2: wet clothing extracts heat from the body up to 240 times faster than dry clothing, which can lead to hypothermia cracking, charring, and discoloration are examples of to a chemical garment degradation the decon of crew memebers through the use of water and soap is known as 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 level A when dealing with a radiological incident involving a leak or spill, what exposure guidelines should be used to minimize radioactive contamination? 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? explosive/mechanical the best type of PPE for thermal hazards would be structural FF clothing the process by which a chemical enters a protective suit through openings in the garment best describes penetration the physical destruction or decomposition of chemical protective clothing by a chemical action is called degradation the maximum hose length allowed by NIOSH when using an airline hose respirator is feet 300 the highest level of respiratory protection is needed but lesser chemical protection is required for the skin best describes protection level b the best protective material against a specific chemical is one that has a low rate (if any) and a long time permeation, breakthrough the elapsed time between initial contact of a chemical with the outside surface of the chemical protective equipment and detection at the inside surface of the material is called breakthrough time the chemical action involving the movement of chemicals, on a molecular level, through intact materials best defines permeation in order to safely estimate the chemical resistance of a particular garment, manufacturers supply compatibility charts there is no assurance that once decon of chemical protective clothing is complete has ceased permeation chemical permeation rates are a result of temperature, thickness, previous exposures, and chemical combinations is the flow of a hazardous material through zippers, pinholes, or other material imperfections found in chemical protective clothing penetration the physical destruction or decomposition of chemical protective clothing material due to exposure to chemicals, general use or ambient conditions defines degredation standard structural FF ensemble including SCBA are adequate for which chemical, biological, radiological, nuclear, and high yield explosives (CBRNE) incidents?

heat stroke lowered body core temp is called hypothermia diking, damming, and diverting are options available for control defensive; spill as a first responder trained to the operations level, which spill control tactics can be conducted? 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 flaring another technique for reducing or controlling pressure and/or disposing of the contents is called flaring is the most commonly used method for decontaminating personnel dilution/washing the eight step process recommended for assessing a hazmat incident includes hazard risk evaluation which principal characteristic of adsorption is true? off gassing is reduced adsorption is the process of adhering the contaminant to a surface a process in which a material is added to soak up a hazardous material to prevent enlargement or spread of the contaminated area is known as adsorption when using water to extinguish a fire involving pesticides or a poison, the responder should consider the impact of run-off contamination at a spill, defensive actions should include diking or remote closing of a valve in some situations, it may be safe and acceptable for Operations-level responders to operate emergency remote shutoff valves on cargo tank trucks. this remote shut off on an Mc 306/DOT 406 will be located at the left front corner which is a true statement regarding the safety precautions of remote shutoffs they are usually well marked in red and in an easy-to-find location which statement is true regarding vapor dispersion? the runoff may need to be contained
