§ 154.820 Fire, explosion, and detonation protection.
(a) A vapor control system with a single facility vapor connection that receives vapor only from a vessel with inerted cargo tanks and processes vapor with a vapor recovery unit must:
(1) Be capable of inerting the vapor collection line in accordance with § 154.824(a) of this subpart prior to receiving vapors from the vessel;
(2) Have at least one oxygen analyzer that samples the vapor concentration continuously at a point not more than 6 meters (19.7 ft.) from the facility vapor connection; and
(3) Meet § 154.824 (f)(1), (f)(2), (g), (h)(2), and (h)(3) of this subpart.
(b) A vapor control system with a single facility vapor connection that receives vapor only from a vessel with inerted cargo tanks and processes vapor with a vapor destruction unit must:
(1) Have a detonation arrester located not more than 6 meters (19.7 ft.) from the facility vapor connection; or
(2) Have an inerting system that meets the requirements of § 154.824 of this subpart.
(c) A vapor control system with a single facility vapor connection that receives vapor from a vessel with cargo tanks that are not inerted and processes vapor with a vapor recovery unit must:
(1) Have a detonation arrester located not more than 6 meters (19.7 ft.) from the facility vapor connection; or
(2) Have an inerting, enriching, or diluting system that meets the requirements of § 154.824 of this subpart.
(d) A vapor control system with a single facility vapor connection that receives vapor from a vessel with cargo tanks that are not inerted and processes the vapor with a vapor destruction unit must:
(1) Have a detonation arrester located not more than 6 meters (19.7 ft.) from the facility vapor connection; and
(2) Have an inerting, enriching, or diluting system that meets the requirements of § 154.824 of this subpart.
(e) A vapor control system with multiple facility vapor connections that processes vapor with a vapor recovery unit must have a detonation arrester located not more than 6 meters (19.7 ft.) from each facility vapor connection.
(f) A vapor control system with multiple facility vapor connections that processes vapor with a vapor destruction unit must:
(1) Have a detonation arrester located not more than 6 meters (19.7 ft.) from each facility vapor connection; and
(2) Have an inerting, enriching, or diluting system that meets the requirements of § 154.824 of this subpart.
(g) A vapor control system that uses a vapor balancing system in which cargo vapor from a vessel is transferred through the facility vapor collection system to facility storage tanks must:
(1) Have a detonation arrester located not more than 6 meters (19.7 ft.) from each facility vapor connection;
(2) Have a detonation arrester located within the storage tank containment area as close as practical to the vapor return connection of each facility storage tank; and
(3) Have facility storage tank high level alarm systems and facility storage tank overfill control systems arranged to prevent cargo from entering the vapor return line.
(h) Except for a discharge vent from a vapor destruction unit, each outlet of a vapor control system that vents to atmosphere and is not isolated with a pressure-vacuum relief valve must have a flame arrester located at the outlet.
