Torch Assembly
•
•
•
•
Liquid Propane Cylinder
Regulator
Hose
Torch
Torch MUST have operable stand!
After inspection of equipment & ensuring fire
extinguisher is present, assemble the torch in
the following sequence:
1. Connect regulator to hose;
2. Connect regulator to cylinder;
3. Release a small amount of gas to remove any
debris that may have been accumulating in the
hose while in storage;
4. Attach the hose to the torch head;
5. With torch head closed, crack valve on cylinder to
permit a small amount of pressure to build up in
hose;
6. Using soap/water solution, check all connections
for bubbles which would indicate a leak is present;
7. Close the valve on the cylinder before retightening
all of the connections.
Leak Test Kit
• Open cylinder slowly
during the leak test
• If leak is detected, close
cylinder valve and
disconnect all parts
• Attempt to reassemble
• If leaks still exist, discontinue
use and replace torch
• Never use open flame to
check for leaks!
• Wear required PPE
• Eye protection, gloves, long clothing to cover skin
• Prepare work area by clearing away debris
• Have extinguishers present and secure propane
tank
• Alert other workers and keep them away
• Open cylinder and keep torch away from body

Flint Striker
Propane Storage

• Never point torch towards
flammable objects or areas you
can not see clearly
