l built up in the cylinder and pressure variations due to temperature.
往可再装瓶子里重新充气时，只要充满到总容量的75%即可，以确保有足够的剩余空间容纳气瓶里的组装材料，适应温度改变所引起的变化的压强。
Gross weight – tare weight = net weight. 毛重 – 自重 = 净重
Net weight x 0.75 = recommended amount to fill a pressurised cylinder.
净重 X 0.75 = 填充恒定气压储气瓶的推荐气量
It is currently expected the law will permit the purchase of R134a only if you hold a DEFRA approved qualification.
现在法律规定只有你拥有一个DEFRA核准资格证书的时候，才允许购买R134a制冷剂。
If needing to dispose of refrigerant/contaminated refrigerant, the use of a certified gas handling/disposal company is essential. A waste transfer notice will need to be completed during the transaction. Liability is not transferrable when it comes to the disposal of hazardous waste, so even if a disposal company provides you with a waste transfer note, as part of your environmental audit the disposal process of the company should be monitored by your organisation.
如果需要处理制冷剂或已受到污染的制冷剂，让一家认证的气体加工、处理公司来做是很重要的。交易期间将需要填一个废物转移通知单。当这家公司要处理危险性废料的时候，责任不可转移，所以即便一个废物处理公司提供给你一个废物转移单，作为你对于环境的一部分责任，公司的废物处理过程必须在你的组织的监督下进行。
Safety 安全
Fluoroelastomer gloves are recommended to protect you from R134a refrigerant and its –26.3c boiling point.
推荐使用氟橡胶手套来保护你不受到R134a制冷剂和它零下26.3℃沸点的伤害。
Always wear gloves, full face goggles and some form of overalls when working on air conditioning systems as this will minimise the risk of frostbite.
在汽车空调系统作业时，要一直戴上手套，面部全包型护目镜和穿上其他防护服装。这样能够将冻伤的几率减小到最低。
Always work in a well- ventilated area as R134a is heavier than air and if inhaled will replace the oxygen in your lungs, potentially leading to suffocation.
工作环境必须一直都通风良好，因为R134a比空气重。一旦吸入R134a，它将取代你肺部的氧气，有可能让人窒息。

Always refer to material data sheets in an employer’s COSHH (Control of Substances Hazardous to Health) file. Employees of a company with more than five people should have seen these sheets and signed to say they have read them. The sheets contain useful information to first aiders and the emergency services.
要一直参照雇主的《危害健康物质控制》（英文简称COSHH）文件中的材料数据表。公司的雇员中应该有五个以上人员看过这些表，并签字表明他们已经看过。这些表包含一些关于急救和紧急服务的实用信息。
Refrigerant must never be used to investigate potential leaks. Leak detection processes involving pressure testing the systems are only allowed if oxygen free nitrogen testing kits (or equivalent) are used.
严禁使用制冷剂来检查可能性泄漏。只有在使用无氧氮气检验工具包（或等效工具）时才允许进行检漏程序，包括检查系统的压强。
Training 培训
As of 15th February 2008 minimum qualifications apply to anyone wishing to recover refrigerant from mobile air conditioning systems. During the period between the 15th February 2008 to 4th July 2010 all personnel must be qualified in one of the qualifications listed in the GB Fluorinated Greenhouse Gases Regulations 2008 (statutory Instrument 2008 No.41). Type it into a search engine and you’ll find it. “Automotive Technician Accreditation – Air Conditioning Refrigerant Handler” is included in the list of minimum requirements.
自2008年2月15日起，每位希望从汽车空调系统中回收制冷剂的人员都要符合本行业最低资格。在2008年2月15日到2010年7月4日之间，所有人员必须符合以下标准，即获得了2008年GB氟化温室气体
