AVOID HEATING NEAR PRESSURIZED FLUID
LINES
•
Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severe burns to
yourself and bystanders.
•
Do not heat by welding, soldering, or using a torch
near pressurized fluid lines or other flammable
materials.
•
Pressurized lines can be accidentally cut when heat
goes beyond the immediate flame area. Install
temporary fire resistant guards to protect hoses or
other materials before engaging in welding, soldering,
etc.
AVOID APPLYING HEAT TO LINES
CONTAINING FLAMMABLE FLUIDS
•
Do not weld or flame cut pipes or tubes that contain
flammable fluids.

Remove flammable fluids thoroughly with
nonflammable solvent before welding or flame cutting
pipes or tubes that contained flammable fluids.
