1. INTRODUCTION
介绍
The following is a description of the safe work practices that are used on the SECCO Project for welding/cutting and other ignition sources such as arc or fuel-gas (acetylene or other gas) cutting and arc or fuel-gas welding.
下面的一项安全工作规定对在赛科项目所使用的焊接/切割及其它动火设备，例如电弧切割/气割（乙炔或其它气体）及电焊/气焊作了说明。
2. GENERAL REQUIREMENTS
总体要求
The following are general requirements for both welding and cutting activities are being performed and whether a fuel-gas or an electric arc is being used.
以下是焊接/切割工作及采用气源或电源的总体要求。
· Prior to using any welding/cutting or ignition source equipment on the project site it is necessary to carefully plan the work. (refer Site Safety Practice No. 23 – Safe Work Planning)
在现场使用任何焊接/切割设备或其它点火源设备之前，首先必须制定相应的工作计划。
· Only a certified welder may perform a welding job. (Approved by QA department)
焊接工作必须由合格的焊工来完成。（由质保部门认可）
· Welders are responsible for the maintenance of their equipment.
焊工负责焊接设备的维护。
· The designated Person-in-Charge of the welding work and the welder shall inspect all welding and burning equipment each day.
负责焊接工作的指定人员及焊工必须每日对所有焊接及切割设备进行检查。
· The welder shall wear the appropriately approved shaded lens and the combination face shield, in addition to their basic PPE.
除了一般的人身保护设备以外，焊工还必须戴经过认可的专用防护面罩及焊镜。
· The welder, welders’ helper and fire watch shall be required to use proper protective clothing such long sleeves, leathers or fire retardant shirts. Helpers and fire watch personal shall also wear approved eye protection.
焊工，焊工助手和监火人员都必须穿戴合适的保护服，例如长袖，皮衣或防火衣。另外，焊工助手和监火人员还必须佩戴被批准的防护眼镜。
· A fire watch mat be required during some critical welding/cutting operations.
在进行某些重要的焊接/切割作业时，通常需要安排一名监火人员。
· Welding/cutting operations shall not be performed in a confined space until the area has been tested for oxygen and flammable materials and the appropriate permits are issued.
在或狭窄区域进行焊接/切割作业之前，首先必须对该区域的氧含量及可燃物进行测试和检查，并出具有关的作业许可证。
· Adequate ventilation shall be provided for welding/cutting operations. If adequate ventilation cannot be provided, respiratory protection must be worn.
进行焊接/切割作业时必须保证足够的通风，否则，作业人员必须戴呼吸保护设备。
· Combustion engine generators must be fitted with approved spark arrestors.
内燃机必须装配经过认可的火星熄灭器。
· No cutting or welding is permitted on steel drums or metal containers under any circumstances.
无论在什么情况下，都不允许在钢罐或金属容器上进行切割或焊接。
3. OXYGEN AND ACETYLENE EQUIPMENT
氧气和乙炔设备
The following are procedures that are particular to the use of oxygen and acetylene equipment:
下列程序专门用于氧气和乙炔设备：
· Oxygen and acetylene hoses shall be protected from sparks and hot slag. The regulators, hoses and flash back arrestors shall be inspected for leaks, wear and loose connections before use (daily). Damaged components such as hoses shall not be used; they must be replaced or repaired.
防止氧气和乙炔软管接触火星及热渣等物质。使用之前（每日），必须对调节器，软管和防回火装置进行检查，确认是否有泄漏，磨损及接头松懈等现象。不得使用已经损坏的部件如软管；损坏的部件必须进行更换或修理。
· Oxygen and acetylene hoses shall be stored in their proper location when not in use. Cylinder valves shall be closed and the pressure bled from the regulator and hoses after each use.
氧气和乙炔软管不使用时应存放在适当的地方。每次使用完毕之后应关闭气瓶上的阀门，并释放调节器和软管的压力。
· Torches shall be inspected for leaky valves, nozzles and/or tips before use (daily).
使用之前（每日），必须对焊枪进行检查，确认阀门，喷嘴和/或枪头是否有泄漏现象。
· Only spark igniters (striker) shall be used to light welding touches. Matches and lighters shall not be used for this purpose.
给焊枪点火时只能使用点火枪，不能使用火柴和打火机。
· Flash back arrestors (check valves) shall be required on both oxygen and acetylene hose systems. Special clip shall be used to ensure reliable connect between hoses and bottles.
氧气和乙炔软管系统必须使用防回火装置（逆止阀）。使用固定夹子保证软管和气瓶的可靠连接。
· All personnel using this equipment must wear approved safety cutting and welding glasses.
使用该设备的所有人员必须戴专用的安全切割及焊接眼镜。
· Oxygen and acetylene bottles shall be deposited solely. Oxygen and acetylene bottles must be stored at least 6.0 meters apart as a minimum and 10 meters away from flame in the site.
氧气瓶和乙炔瓶应分开储存。在现场氧气和乙炔瓶至少应间隔6米存放且离开明火不小于10米。
4. ELECTRIC ARC WELDING
电焊
The following are procedures that are particular to the use of electric arc welding equipment:
下列程序专门用于电焊设备：
