§ 193.50-1 - Application.
(a) The provisions of this subpart, with the exception of § 193.50-90, apply to all vessels, including non-self-propelled vessels of less than 300 gross tons, contracted for on or after March 1, 1968.
(b) All vessels other than unmanned barges contracted for prior to March 1, 1968, must meet the requirements of § 193.50-90.
(c) All unmanned barges are exempted from the requirements in this subpart. However, if such barges carry on board hand portable fire extinguishers and semi-portable fire extinguishing systems, then such equipment must be in accordance with this subpart for manned barges.
§ 193.50-10 - Location.
(a) Approved portable fire extinguishers and semi-portable fire extinguishing systems must be installed in accordance with Table 193.50-10(a) of this section. The location of the equipment must be to the satisfaction of the Officer in Charge, Marine Inspection (OCMI). Nothing in this paragraph must be construed as limiting the OCMI from requiring such additional equipment as he or she deems necessary for the proper protection of the vessel.
(b) Table 193.50-10(a) indicates the minimum required classification for each space listed. Extinguishers with larger numerical ratings or multiple letter designations may be used if the extinguishers meet the requirements of the table.
(c) Semi-portable fire extinguishing systems must be located in the open so as to be readily seen.
(d) If portable fire extinguishers are not located in the open or behind glass so that they may be readily seen, they may be placed in enclosures together with the firehose, provided such enclosures are marked as required by § 196.37-15 of this subchapter.
