Oil fuel transfer pumps are not considered as oil fuel units. Regulation II-2/22.214.171.124.5 Protection from cargo area For the portions which face the cargo area, the A-60 class insulation should be provided up to the underside of the deck of the navigation bridge. Regulation II-2/9.3.1 Penetrations in fire-resistive divisions and prevention of heat transmission This regulation should be applied to all penetrations at the exterior boundaries of superstructures and deckhouses which, according to SOLAS regulation II-2/126.96.36.199.5, are required to be A-60 class insulated. Regulation II-2/10.7.1.4 Fixed gas fire-extinguishing systems for general cargo 1 Non-combustible cargoes, such as materials listed in paragraph 1 of Annex 2 to the FTP Code, need not be mentioned on exemption certificates issued under regulation II-2/10.7.1.4. 2 The document of compliance with regulation II-2/19 may not permit more cargoes than indicated in the list of cargoes attached to the exemption certificate issued under regulation II-2/10.7.1.4.

See IEC 60092-506 table B1, item B. 3 Enclosed spaces (e.g., pipe tunnels, bilge pump-rooms, etc.) containing such pipes with equipment such as flanges, valves, pumps, etc., should be regarded as an extended hazardous area, unless provided with overpressure in accordance with IEC 60092-506 clause 7. Resolution A.754(18) Fire resistant windows in tankers Windows to be fitted at the forward bulkhead of accommodation block on tankers should correspond to prototype subjected to the A class standard fire test with the fire against its external side (i.e., the side which, after the installation on board, will be exposed to the weather). The insulation of the bulkhead used along with the windows specimen should be fitted on the unexposed face of the structural core. __________
