(1) NFPA 70 Articles 500 through 504 (incorporated by reference, see § 110.10-1 of this subpart). Equipment identified for Class I locations must meet the provisions of Sections 500.7 and 500.8 of NFPA 70 and must be tested and listed by an independent laboratory to any of the following standards: (i) ANSI/UL 674, ANSI/UL 823, ANSI/UL 844, ANSI/UL 913, ANSI/UL 1203, ANSI/ISA 12.12.01, and/or ANSI/UL 2225 (incorporated by reference, see § 110.10-1). (ii) FM …

46 CFR §177.405

§ 177.405 General arrangement and outfitting. (a)The general construction of the vessel must be such as to minimize fire hazards insofar as it is reasonable and practicable. (b)Internal combustion engine exhausts, boiler and galley uptakes, and similar sources of ignition must be kept clear of and suitably insulated from combustible material. Dry exhaust systems for internal combustion engines on wooden or fiber reinforced plastic vessels must be installed in accordance with ABYC P-1 (incorporated by reference, see 46 CFR 175.600). (c)Machinery and fuel tank spaces must be separated from accommodation spaces by boundaries that prevent the passage of vapors. (d)Paint and flammable liquid lockers must be constructed of steel or equivalent material, or wholly lined with steel or equivalen…

46 CFR §182.430

§ 182.430 Engine exhaust pipe installation. (a) The design of all exhaust systems must ensure minimum risk of injury to personnel. Protection must be provided in compliance with § 177.970 of this chapter at such locations where persons or equipment might come in contact with an exhaust pipe. (b) Exhaust gas must not leak from the piping or any connections. The piping must be properly supported by noncombustible hangers or blocks. (c) The exhaust piping must be so arranged as to prevent backflow of water from reaching engine exhaust ports under normal conditions. (d) Pipes used for wet exhaust lines must be Schedule 80 or corrosion-resistant material and adequately protected from mechanical damage. (e) Where flexibility is necessary, a section of flexible metallic hose may be used. Non…

46 CFR §183.530

§ 183.530 Hazardous areas. (a) Electrical equipment in spaces containing machinery powered by, or fuel tanks for, gasoline or other fuels having a flashpoint of 43.3 °C (110 °F) or lower must be explosion-proof or ignition-protected, or be part of an intrinsically safe system. (b) Electrical equipment in lockers used to store paint, oil, turpentine, or other flammable liquids must be explosion-proof or be part of an intrinsically safe system. (c) Explosion-proof equipment and intrinsically safe systems must meet the requirements of § 111.105 in subchapter J of this chapter.

46 CFR §28.380

§ 28.380 § 28.380 General structural fire protection. (a)Each vessel must be constructed so as to minimize fire hazards insofar as is reasonable and practicable. (b)An internal combustion engine exhaust, galley uptake, electrical heating tape, or similar source of ignition must be kept clear of and suitably insulated from combustible material. A dry exhaust system for an internal combustion engine on a wooden or fiber reinforced plastic vessel must be installed in accordance with ABYC P-1. (c)(1) Each accommodation space must be separated from machinery and fuel tank spaces by a fire resistant boundary which will prevent the passage of vapors. (2) Each pipe and cable penetration between an accommodation space and a machinery or a fuel tank storage space must be sealed. (d)Each vessel …
