SAFETY INSTRUCTIONS 

WX210 - WX240

 

 

 

 

Preventing heat build-up close to pressure 
systems 

Preventing heat build-up in lines carrying 
combustible fluids 

 

 

 

Heat generation close to pressur-
ized fluid lines may result in a 
highly flammable spray, putting 
you and other persons in the im-
mediate vicinity at risk of serious 
scalding. 

Never carry out heat-generating 
welding or soldering work close to 
pressurized fluid lines or other 
highly flammable substances, and 
never use a flame cutter there. 

Pressure lines may be inadver-
tently cut if the heat goes beyond 
the immediate flame area. To pro-
vide temporary protection for 
hoses or other materials, mount 
fire-resistant shields when carrying 
out welding or soldering work. 

- 

Never carry out welding or flame-
cutting work on pipes or lines car-
rying combustible fluids. 

- 

Flush them out with a non-flam-
mable solution before welding or 
flame-cutting them.
