CYLINDERS FOR COMPRESSED GASES

压缩气瓶

 

1          Cylinders for compressed gases are manufactured, filled, inspected and tested in accordance with specific regulations. Relevant regulations must be identified and made available for review. Relationships between regulations and work instructions must be explained to employees.

压缩气瓶的制造，充装，检查，测试都要按特定规章进行，这些规章可用于评审，向员工讲明规章与工作指引的关系。

 

2          High pressure gas cylinders are made of steel, aluminium alloys or composite materials. Cylinder valves need be permanently protected with a removable or permanent (open) cap.

高压气瓶是由钢制，铝合金，或复合材料制成的，瓶阀必须用活动的或不活动的防护帽保护。

 

3          Valve outlets are also made in conformity with standards and national specifications. In order to avoid confusion between flammable and non-flammable gases, the valves on flammable gas cylinders have a left hand outlet thread and those on non-flammable gas cylinders have a right hand outlet thread. (Hydrogen left hand ; oxygen, nitrogen and argon right hand).

阀的接口要按国家标准和规划制造，避免可燃和不可燃气体的混淆，可燃气阀接口螺纹左旋，不可燃气阀接口螺纹右旋，（氢左旋，氧，氮，氩右旋。）

 

4          The gaseous contents of cylinders are identified by adhesive labels, stencilling and permanent stamping (not in all countries) and a system of colour coding allows consistent identification in all of the European Union countries.

气瓶内气体的成分由所贴标签，印刷品，或永久铅印（不是所有国家）鉴别，欧共体国家采用一致颜色码系统鉴别。

5.2.      Never stamp mark a cylinder unless you are authorised to do so.

除非是受权人，你不要打钢印。

 

5.3.      Only fill cylinders which carry the correct identification.

只有能正确识别的气瓶才能充装；

 

6         Cylinders have to be subjected to inspection and hydraulic testing by the manufacturer before they can be put into service.

气瓶出厂前必须由厂家检验和水压试验。

 

7          Cylinders have to be inspected and/or hydraulically tested at set intervals throughout their working life.

使用寿命内气瓶必须在规定周期内检验和水压试验。

 

7.1.      Obtain from your supervisor the rules which apply to the cylinders which you will be handling and learn how to read testing dates on cylinders.

从主管获得有关气瓶的规定，以及识别检验日期的方法。

 

7.2.      Never fill a cylinder which has not been tested or examined within the appropriate period.

在适当时期没有检测的气瓶不予充装。

 

8          A cylinder which is in a satisfactory condition to be filled must conform to the following :

符合气瓶充装时应满足以下条件：

·         it must not be soiled,

没污染

·         pressure test date must be valid,

在有效试压期内；

·         it must not show any physical damage such as dents, burn marks,.

没物理损伤如：凹痕，烧伤痕迹。..

·         it must not be rusty,

绝对不可以生锈

·         it must be free from corrosion by chemicals,

必须避免化学品腐蚀

·         maximum allowed working pressure must be consistent with filling pressure and over pressure protections of filling rack,

最大许用压力与充装压力及充装排过压保护相一致；

·         the valve must be of the correct type, clean and in good condition,

阀门必须正确型号，清洁且状态完好；

·         the residual contents must be the same gas as indicated by label and colour, the valve protecting cap must be available.

残余气必须与瓶标签和颜色相一致；

 

8.1.      Examine all cylinders before filling to see that they are in a satisfactory condition.

充装前要检验所有的气瓶在良好状态。

 

8.2.      Report to your supervisor any cylinders which you consider to be unsatisfactory.

发现不满意气瓶报告主管；

 

9          Cylinders standing on uneven surfaces and cylinders with defective foot rings are unstable and may fall down.

气瓶放在不平地面或气瓶瓶脚损坏，会导致不稳，且会倒瓶。

 

Cylinders which are standing unattended and unsupported may be knocked over ; in falling, they may hit other cylinders and cause them to fall.

气瓶没固定会被碰倒，碰击其它气瓶，使它们倾倒；

 

9.1.      Always let cylinders stand on flat and level surfaces and secure them (chains, pallets,...).

不要让气瓶单独立放于容易碰倒的地方；

 

10        Never transfill cylinders without the appropriate qualification, procedures and equipment.

没有资格、程序和设备的情况下，不要瓶对瓶互充，

 

11        Adapters to convert cylinder valves from one type of gas to another can lead to contamination and serious accidents. Their use is forbidden.

Always close the bar or gate when not handling cylinders in a pallet and lock the bar open when handling cylinders.

将气瓶放进或取出瓶组架时，确保瓶组架状态良好，发现缺陷报告主管，松开瓶的固定带，保证瓶的稳定后，再打开瓶卡的门或拉杆。不要试图抓住要倒的瓶，保持清醒头脑，不操作瓶卡时关住门或拉杆，操作瓶时将拉杆松开。
