2.5  Prevent fire, explosion, burns and injury caused by heated workpiece, spatters, slag, 

and arc sparks right after welding as described below. 

 

●Do not weld near flammable materials. 

●Watch for fire: keep a fire extinguisher nearby. 

●NEVER do welding on inflammables such as a piece of wood or 

cloth. 

 

WARNING 

●Do not weld on closed containers. 

●Heated workpiece, spatters, slag and arc sparks right after welding 

may cause fire. 

●Incomplete cable connections, incomplete contacts in the current 

circuit of the workpiece such as steel frames may cause a fire due to 
the heat generated when powered. 

●Arc generated on containers of inflammables such as gasoline may 

cause an explosion. 

●Welding of airtight tanks and pipes may cause a bursting. 

 

●Touching a heated workpiece, spatters, slag or arc sparks will 

cause a serious burn. 

 
1)  KEEP FLAMMBLE MATERIALES out of the robotic cell. 
2)  Welders  should  wear  appropriate  protection  such  as  flameproof  leather  gloves,  work  clothes 

with long sleeves, a leg cover, a flameproof leather apron in order to prevent burns caused by 
touching heated workpiece, spatters, slag and arc sparks right after welding..         

3)  WATCH for fire. 
4)  Have a fire extinguisher nearby. Operators should know how to use it. 
5)  DO NOT touch heated workpiece and peripheral jigs with inflammables such as a piece of wood 

or cloth.    Doing so might cause not only a fire but also burns. 

6)  DO NOT put heated workpiece close to inflammables right after welding. 
7)  Remove inflammables from the place where welding is carried out so that spatters and slag will 

not strike them. 

8)  Do not use inflammable gases near the welding sight. 
9)  Tighten and insulate the cable connections completely. 

10)  Connect the cables on the workpiece side as close to the welding area as possible to prevent 

the  welding  current  from  traveling  along  unknown  paths  and  causing  electric  shock  and  fire 
hazards. 

11)  A  gas  pipe  with  gas  sealed  in,  an  airtight  tank  and  a  pipe  must  not  be  welded  because  they 

might explode. 

12)  NEVER do welding on inflammables such as a piece of wood or cloth. 
13)  When welding a large-size structure such as a ceiling, floor, wall, etc., remove any inflammables 

hidden behind a workpiece.
