有没有人知道这是什么东西？

船舶原理老师让我们翻译的，只给了我们打印版的，没有给电子版的，我现在翻译起来还得一个单词一个单词地输入电脑，很麻烦，有没有人知道这到底是什么东西？在哪里可以有电子版的？

最近实在是很忙，老师还布置这种跟课程一点关系都没有的作业，郁闷死了。。。

全文我打出来了。。。求大神翻译~~~不胜感激~~~

14A.4.2 Ventilation ducts for Category 'A' machinery spaces,galleys,spaces containing vehicles or craft with fuel in their tanks,or lockers storing such fuels,are generally not to pass through accommodation spaces,service spaces or control stations. Where this is unavoidable, the trunking should be constructed of steel at least 3mm thick or equivalent to the satisfaction of the administration. The ducting within the accommodation should be fitted with:

1.fire insulation to A-30 (B-0 on Short Range Yachts) standard to a point at least 5 metres from the machinery space or galley;

and2.automatic fire dampers located in the deck or bulkhead within the accommodation where the trunking passes from the machinery space or galley into the accommodation.These automatic fire dampers are also to be manually closable from outside the galley or machinery space.

14A.4.3 Ventilation ducts for accommodation spaces，service spaces or control stations are not to pass through Category 'A' machinery spaces，spaces containing vehicles or craft with fuel in their tanks，or lockers storing such fuels，unless the ducts are constructed of steel and arranged to preserve the integrity of the division.

14A.4.4 Store-rooms containing highly flammable products are to be provided with ventilation arrangements that are separate from other ventilation systems. Ventilation is to be arranged to prevent the build up of flammable vapours at high and low levels。The inlets and outlets of ventilators are to be positioned so that they do not draw from or vent into an area which would cause undue hazard，and are to be fitted with spark arresters。

14A.4.5 Ventilation systems serving Category 'A' machinery spaces are to be independent of systems serving other spaces。

14A.4.6 All enclosed spaces containing free standing fuel tanks are to be ventilated independently of systems serving other spaces。

14A.4.7 Ventilation is to be provided to prevent the accumulation of dangerous concentrations of flammable gas which may be emitted from batteries。

14A.5   Arrangements for Gaseous Fuel for Domestic Purposes

14A.5.1 Where gaseous fuel is used for domestic purpose，the arrangements for the storage，distribution and utilisation of the fuel is to be such that，having regard to the hazards of fire and explosion which the use of such fuel may entail，the safety of the yacht and the persons onboard is preserved。The installation is to be in accordance with recognised National or International Standards。Hydrocarbon gas detectors and carbon monoxide detectors should be provided。

14A.5.2 Gas cylinders，regulators and safety devices should be stowed on the open deck （where leakage will not accumulate）or in a compartment that is vapour-tight to the vessels interior，and fitted with a vent and drain，so that any gas which may leak can disperse overboard。

14A.5.3 An open flame gas appliance provided for cooking，heating or any other purpose should comply with the requirements of EC Directive 90/396/EEC or equivalent。   
The installation of an open flame gas appliance should comply with the appropriate provisions of Annex 3。

14A.6   Space Heaters        
Space heaters，if used，are to be fixed in position and so constructed as to reduce fire risks to a minimum。The design and location of these units is to be such that clothing，curtains or other similar materials cannot be scorched or set on fire by heat from the unit。

14A.7   Fixed Fire Detection and Fire-Alarm Systems      
The purpose of this section is to detect a fire in the space of origin and to provide for an alarm for safe escape and fire-fighting activity。   
A fixed fire detection and fire-alarm system is to be fitted in all enclosed spaces except those containing no significant fire risk（toilets，bathrooms，void space，etc）。Manually operated call points shall be placed effectively to ensure a readily accessible means of notification。The fixed fire detection and fire-alarm system is to be installed in accordance with the requirements of SOLAS II-2/7 and the IMO Fire Safety Systems Code，Chapter 9。

14A.8   Fixed Fire Extinguishing Systems Not Required by this Section     
Where a fixed fire extinguishing system not required by this Chapter，is installed，the arrangement is to be the satisfaction of the Administration。
