商业楼宇的 气体安全 Gas Safety of Commercial Premises 除非该商业楼宇内没有煤气或中央石油气供应, 否则不可使用石油气瓶,以供气给固定气体用具 作燃气用途.

若必须使用石油气瓶供气给固定气 体用具,则用户须聘请注册气体工程承办商建造 一个石油气瓶储存室.有关石油气瓶储存室的技 术要求,请参阅《气体应用守则之六:商业楼宇 内作供应饮食用途之石油气装置规定》. 根灏踩趵,除非取得气体安全监督的批 准,否则不得储存总标称容水量超过130升(约50 公斤)的石油气瓶(包括空瓶).一般常用的石油气 瓶的标称石油气重量由2公斤到22公斤不等,下 表列出一些普通型号石油气 瓶的最多许可储存数目,以 供参考. LPG cylinders should not be used in commercial premises to supply gas to fixed gas appliances for combustion purposes unless town gas or a central LPG supply system is not available. If it is necessary to install LPG cylinders for use by fixed gas appliances, customers should employ registered gas contractors to construct LPG cylinder storage chambers. Please refer to GU 06: LPG Installations for Catering Purposes in Commercial Premises for technical requirements of the LPG cylinder storage chambers. According to the Gas Safety Ordinance, unless specifically approved by the Gas Authority, storing LPG cylinders (including empty cylinders) with a total nominal water capacity of over

130 litres (about

50 kg) is prohibited. The nominal LPG weight of commonly used LPG cylinders ranges from

2 kg to

22 kg. For general reference, the following table shows the 石油气瓶的储存 Storage of LPG Cylinders maximum number of cylinders permitted for some common sizes of LPG cylinders. 此外,石油气瓶须直立放置在通风良好和容易到 达的地方,并远离热源及火源.当更换气瓶时, 这点犹为重要.由於石油气比空气重,为避免气 体积累,不可在地平面以下的地方、排水沟附近 或地库内使用或存放石油气瓶.因此,设於地库 的厨房或地平面以下的座位区是不得使用石油 气. 并且,石油气瓶不可放置在公众地方,以免影响 公众安全.使用完毕后的石油气瓶,应尽快交回 石油气分销商,不可随意弃置. Besides, LPG cylinders should be stored upright in a well-ventilated and readily accessible location and kept away from heat and flames, especially when exchanging cylinders. As LPG is heavier than air, to avoid accumulation of gas, do not use or keep LPG cylinders below ground level, adjacent to drains or in basements. Therefore, LPG should not be used in basement kitchens or seating areas below ground level. Moreover, for public safety, do not put LPG cylinders in public places. Used cylinders should be returned to LPG distributor as soon as possible and should not be disposed. 1. 熄灭附近所有火种,不可吸烟. Extinguish all nearby flames, and do not smoke. 2. 关掉气体用具. Switch off gas appliances. 3. 关掉并拆除调压器,然后更换用罄的石油气瓶. Switch off and disconnect the pressure regulator, then replace the used LPG cylinder. 4. 小心地将调压器稳固接驳,然后检查气瓶接 驳位确保没有泄漏石油气的气味M声音. Re-connect the pressure regulator carefully and firmly and check that there is no smell/sound of gas leaking from the cylinder connection. 5. 开启调压器,然后检查气体炉具是否操作正常. Switch on the pressure regulator, and check your gas appliances for proper operation. 应向获批准的石油气分销商购买石油气瓶.所有 石油气分销商都受注册气体供应公司监察.获批 准的分销商会聘用注册气体装置技工向顾客提供 服务,令使用时更为安全.该等分销商的店m内 会展示出所属注册气体供应公司发出的证书,而 发票上亦会显示注册气体工程承办商号码,以供 市民识别.用户也可从机电工程署网页浏览获批 准的分销商名册. LPG cylinders should be purchased from approved LPG distributors. AII LPG distributors are subject to monitoring of registered gas supply companies. 更换石油气瓶的正确步骤 Steps to Exchange LPG Cylinders Approved LPG distributors would employ registered gas installers to provide services for customers to ensure the safety in using LPG cylinders. An approved LPG distributor would display a certificate issued by a respective registered gas supply company in the shop and would also show a registered gas contractor number on invoice for identification. Customers may browse a list of approved distributors on the EMSD website. 为确保气体安全,用户应每12个月安排为气体装 置及炉具进行一次安全检查及维修保养;

气体接 驳软喉亦应定期检查及在使用期限前更换.这类 工作必须由受雇於注册气体工程承办商及领有适 当类别的注册气体装置技工进行. 注册气体工程承办商完成检查后会填写报告,该 报告须列明检查细节及维修建议(如需要),住 户可以向承办商索取报告副本作参考.如有需要 进行任何维修,应适时作出跟进及安排.注册气 体工程承办商应保留过去的检查报告作记录,以 便安排下次的安全检查. To ensure gas safety, users should arrange regular inspection and maintenance of their gas installations and appliances once every

12 months. Flexible gas tubing should also be inspected regularly and replaced before expiry date of its service life. Such inspection and maintenance works must be carried out by registered gas installers registered to the appropriate class and employed by registered gas contractors. 定期的气体安全检查 Regular Gas Safety Inspections The registered gas contractor will complete an inspection report upon completion of the inspection. The report shall list out the inspection details and maintenance advice (if necessary). The occupant may obtain a copy of this report from the contractor for reference. If there is any maintenance needed to be conducted, arrangements for follow-up action should be made in a timely manner. The registered gas contractor should keep past inspection reports for record and arrangement for the next safety inspection. 如需要气体安全的进一步资料,请联络相关注册 气体工程承办商、致电政府热线1823或浏览机 电工程署网页: www.emsd.gov.hk.

2018 商业楼宇的气体燃料 Gaseous Fuels for Commercial Premises 一般商业楼宇使用的气体燃料是煤气或石油气. 煤气的主要成份是氢气和甲烷,比空气轻,并经 管道输送至各用户;

而石油气则主要是丁烷和丙 烷的混合物,比空气重,多是经压缩后以液态储 存於气瓶内以供使用,但亦有由中央管道式石油 气供气系统输送至各用户. 煤气与石油气是安全可靠的气体燃料.但若果使 用不当,可引致严重的气体事故. The common gaseous fuels for commercial premises are town gas and liquefied petroleum gas (LPG). The main constituents of town gas are hydrogen and meth........
