Section 1918.82 - Equipment Standards(a) General. Equipment utilized in gasoline vapor recovery shall be tested according to the requirements set forth in the following applicable standards. (1) Flame Arrestors. Flame Arrestors to be installed in either fuel, vapor, or vent lines shall be tested in accordance with the requirements of U.L. Standard 525, available from Underwriters Laboratories, Inc., 333 Pfingsten Road, Northbrook, IL 60062, and as approved by the State Fire Marshal.(2) Hose Nozzle Valves. Hose nozzle valves used in conjunction with gasoline vapor recovery systems shall be tested in accordance with the requirements of U.L. Standard 842, available from Underwriters Laboratories, Inc., 333 Pfingsten Road, Northbrook, IL 60062, and as approved by the State Fire Marshal.(3) Carbon/Charcoal Canisters. Carbon/charcoal canisters utilized in gasoline vapor recovery systems shall withstand, without failure, a test pressure of plus or minus 150% of the maximum operating pressure. The canister material shall also be able to withstand temperatures created by the materials contained therein.(4) Pressure Regulators. Gasoline vapor pressure regulators utilized in a vapor recovery system shall be approved for the intended use.(5) Ignition Controls. Ignition controls including, but not limited to, such devices as flame detectors, flame sensors, ignition transformers, electrical control units, alarms, flame indicators, utilized as a component of a gasoline vapor recovery system shall be approved by the State Fire Marshal for its intended use.(6) Refrigeration Units. Refrigeration units utilized in processing vapors in gasoline vapor recovery systems shall be approved for their intended use.(7) Pressure/Vacuum Valves. Pressure/vacuum valves utilized in gasoline vapor recovery systems shall be approved by the State Fire Marshal for their intended use.(8) Internal Explosion/Ignition Test. The processing unit shall be subjected to a series of internal explosion/ignition tests, during performance/operation safety testing, such that ignition of an explosion air/gasoline vapor mixture occurs within the confines of the processing unit piping. The explosion shall not propagate beyond the inlet Flame Arrestor(s). The processing unit and Flame Arrestors shall provide a degree of isolation between other installation components and the processing unit, and between the processing unit and the remainder of the installation, and between the processing unit and the storage tank. The operating function of the unit, shall not be impaired as a result of such tests. Adequate sensors shall be utilized to insure that: (1) an explosive gasoline/air vapor mixture was present;(2) that an ignition of the vapor mixture did occur; and(3) that the safeguards installed in the processing unit did function.(9) Other Equipment. Such other equipment which may be utilized in gasoline vapor control systems shall also be tested to applicable standards as may be determined necessary by the State Fire Marshal.Cal. Code Regs.
