FDNY CoF G71 Exam Practice Exam Questions And Answers Verified 100% Correct BULK NITROUS OXIDE SYSTEM - ANSWER -An assembly of equipment as described in the definition of bulk oxygen system that has a storage capacity of more than 3200 lb [approximately 28,000 ft3 (at normal temperature and pressure)] of nitrous oxide. BULK OXYGEN SYSTEM - ANSWER -An assembly of equipment such as oxygen storage containers, pressure regulators, pressure relief devices, vaporizers, manifolds, and interconnecting piping that has a storage capacity of more than 20,000 ft3 of oxygen (at normal temperature and pressure) including unconnected reserves on hand at the site. COMPRESSED GAS - ANSWER -A material, or mixture of materials that is a gas at 68F or less at 14.7 psia of pressure; and has a boiling point of 68oF or less at 14.7 psia that is either liquefied, nonliquefied or in solution at that temperature and pressure, except that gases which have no other health- or physical-hazard properties are not considered to be compressed until the pressure in the packaging exceeds 41 psia at 68F. Nonliquefied compressed gases - ANSWER -Gases, other than those in solution, that are in a packaging under the charged pressure and are entirely gaseous at a temperature of 68F. Liquefied compressed gases - ANSWER -Gases that, in a packaging under the charged pressure, are partially liquid at a temperature of 68oF. Compressed gases in solution - ANSWER -Nonliquefied gases that are dissolved in a solvent. Compressed gas mixtures - ANSWER -A mixture of two or more compressed gases contained in a single packaging, the hazard properties of which are represented by the properties of the mixture as a whole. COMPRESSED GAS CONTAINER - ANSWER -A pressure container designed to hold compressed gases at pressures greater than one atmosphere at 68oF. COMPRESSED GAS SYSTEM - ANSWER -An assembly of components, such as containers, reactors, pumps, compressors and connecting piping and tubing, designed to contain, distribute or transport compressed gases. CONTAINER - ANSWER -For solid and liquid hazardous materials, a vessel of 60 gallons or less in capacity used for storage or transportation. For compressed gases, a cylinder, pressure vessel or tank designed for pressures greater than one atmosphere at 68°F. Pipes, piping systems, engines and engine fuel tanks associated with solid or liquid hazardous materials or compressed gases, shall not be deemed to be containers if in active use. CONTAINMENT SYSTEM - ANSWER -A gas-tight recovery system comprised of devices or equipment which, when placed over or around the portion of the compressed gas container that is leaking, stops or controls the escape of gas from the container. CONTAINMENT VESSEL - ANSWER -A gas-tight vessel which, when installed or placed over or around a leaking compressed gas container, confines the container and the gas leaking therefrom. CONTROL AREA - ANSWER -Spaces within a building that are enclosed and bounded by exterior walls, fire walls, fire barriers and roofs, or a combination thereof, where quantities of hazardous materials not exceeding the maximum allowable quantities per control area are stored, handled or used, including any dispensing. CRYOGENIC CONTAINER - ANSWER -A pressure container, low-pressure container or atmospheric container of any size designed or used for the transportation, handling or storage of a cryogenic fluid, and which utilizes venting, insulation, refrigeration or a combination thereof to maintain the pressure within design parameters for such container and to keep the contents in a liquid state. CRYOGENIC FLUID - ANSWER -A fluid having a boiling point lower than -130 °F at 14.7 pounds per square inch absolute (psia) (an absolute pressure of 101.3 kPa). DISPENSING - ANSWER -The pouring or transferring by other means of any material from a container, tank or similar vessel, which would release dusts, fumes, mists, vapors or gases to the atmosphere, unless such release is prevented by a device, equipment or system designed for that purpose. DOTn - ANSWER -United States Department of Transportation. EMERGENCY OXYGEN SUPPLY CONNECTION - ANSWER -An assembly of equipment which permits a gas supplier to make a temporary connection to supply oxygen to a building which has had its normal source of oxygen disconnected. EXCESS FLOW VALVE - ANSWER -A valve inserted into a compressed gas container that is designed to shut off the flow of gas in the event that its predetermined flow is exceeded. EXCESS FLOW CONTROL. - ANSWER -A fail-safe system or other approved device, equipment or system designed to shut off flow caused by a rupture in a pressurized piping system. EXHAUSTED ENCLOSURE - ANSWER -A device, typically consisting of a hood equipped with a fan that serves to capture and exhaust fumes, mist, vapors and gases generated at a workstation or other local environment. An exhausted enclosure does not include a room provided with general ventilation. FLAMMABLE GAS - ANSWER -A material which is a gas at 68°F or less at 14.7 pounds per square inch absolute (psia) of pressure which: 1. Is ignitable at 14.7 psia when in a mixture of 13 percent or less by volume with air, in accordance with testing procedures set forth in ASTM E 681;
