Wetting Agent Reharging - CORRECT ANSWER The agent in stored-pressure wetting agent fire extinguishers shall be replaced annually AFFF and FFFP Recharging - CORRECT ANSWER The premixed agent in liquid charge-type AFFF and FFFP fire extinguishers shall be replaced at least once every 3 years. Recharge Agents - CORRECT ANSWER Only those agents specified on the nameplate or agents proven to have equal chemical composition, physical characteristics, and fire-extinguishing capabilities shall be used Mixing of Dry Chemicals - CORRECT ANSWER Multipurpose dry chemicals shall not be mixed with alkaline-based dry chemicals Topping Off - CORRECT ANSWER The remaining dry chemical in a discharged fire extinguisher shall be permitted to be re-used, provided that it is thoroughly checked for the proper type, contamination, and condition. Dry Chemical Agent Re-Use - CORRECT ANSWER The dry chemical agent shall be permitted to be reused, provided a closed recovery system is used and the agent is stored in a sealed container to prevent contamination Dry Chemical Closed Recovery System - CORRECT ANSWER A system that is constructed in a manner that does not introduce foreign material into the agent being recovered and has a means of visually inspecting the recovered agent for contaminants Dry Powder - CORRECT ANSWER Pails or drums containing dry powder agents for scoop or shovel application for use on metal fires shall be kept full and sealed with the lid provided with the container. The dry powder shall be replaced if found damp Removal of Moisture - CORRECT ANSWER For all non-water types of fire extinguishers, any moisture shall be removed before recharging Halogenated Agent. - CORRECT ANSWER Halogenated agent fire extinguishers shall be charged with only the type and weight of agent specified on the nameplate Halogenated Agent Re-Use - CORRECT ANSWER The removal of Halon 1211 from fire extinguishers shall be done using only a listed halon closed recovery system. Carbon Dioxide - CORRECT ANSWER The vapor phase of carbon dioxide shall be not less than 99.5 percent carbon dioxide Water Types - CORRECT ANSWER The amount of liquid agent shall be determined by using one of the following: (1) Exact measurement by weight (2) Exact measurement by volume (3) Anti-overfill tube, if provided (4) Fill mark on fire extinguisher shell, if provided Wet Chemical and Water Mist Agent Re-Use - CORRECT ANSWER Wet chemical and water mist agents shall not be reused.If a wet chemical or water mist extinguisher is partially discharged, all remaining wet chemical or water mist shall be discarded. Wet chemical or water mist agent shall be discarded and replaced at the hydrostatic test interval. Only the agent specified on the extinguisher nameplate shall be used for recharge. Recharging Expellant Gas for Stored-Pressure Fire Extinguishers. - CORRECT ANSWER Only standard industrial-grade nitrogen with a maximum dew point of −60°F (−51°C), in accordance with CGA G-10.1, Commodity Specification for Nitrogen, shall be used to pressurize stored-pressure dry chemical and halogenated-type fire extinguishers that use nitrogen as a propellant A regulated source of pressure, set no higher than - CORRECT ANSWER 25 psi (172 kPa) above the operating (service) pressure, shall be used to pressurize fire extinguishers The gauge used to set the regulated source of pressure - CORRECT ANSWER shall be calibrated at least annually Recharge Record Keeping - CORRECT ANSWER Each fire extinguisher shall have a tag or label attached that indicates the month and year recharging was performed, identifies the person performing the service, and identifies the name of the agency performing the work Each extinguisher that has been recharged - CORRECT ANSWER shall have a verification-of-service collar located around the neck of the container, except as identified in 7.11.4. Fire extinguishers shall not be converted from one type to another, modified, or altered. - CORRECT ANSWER True Fire extinguishers shall not be converted for the use of a different type of extinguishing agent. - CORRECT ANSWER True Maintenance and Recharge Service Collar. Each extinguisher that has undergone maintenance that included internal examination or that has been recharged requiring the removal of the valve assembly shall have - CORRECT ANSWER a verification-of-service collar located around the neck of the container The verification of service collar shall, as a minimum, identify the following: - CORRECT ANSWER (1) Month and year the recharging or internal examination was performed (2) Name of the agency performing the work New extinguishers requiring an initial charge in the field (such as pressurized water, AFFF, FFFP, or wet chemical extinguishers) - CORRECT ANSWER shall not be required to have a verification-of service collar installed Liquefied gas, halogenated agent, and carbon dioxide extinguishers that have been recharged without valve removal - CORRECT ANSWER shall not be required to have a verification-of-service collar installed following recharge Cartridge- and cylinder-operated extinguishers - CORRECT ANSWER shall not be required to have a verification-of-service collar installed.
