33 CFR 154.820 - Fire, explosion, and detonation protection.

§ 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.

      Final rule; information collection approval.
      The collection of information requirements contained in the July 16, 2013 final rule (78 FR 42596) and approved by the OMB as an amendment to existing collection of information, control number 1625-0060, will be enforced beginning September 10, 2015. The requirements include provisions for VCS certifications, recertifications, periodic operational reviews, approval requests, reviews of operating manuals, failure analyses, operational review letters, and relabeling. These requirements aid the Coast Guard and industry in ensuring industry's regulatory compliance and safe practices in connection with VCSs.
