1 NERI TORCH TRAINING PART III SAFE PROPANE TORCH USAGE

2 Personal Protective Equipment Personal Protective Equipment is not optional: Work boots that cover the ankle – no frayed shoelaces Long cotton pants Long sleeve shirts - sleeves unrolled to wrist Leather or heavy cotton gloves ANSI Z-87.1 Safety goggles or glasses

3 Proper Torch Assembly Follow all Manufacturer’s Recommendations Use only approved connection equipment Hand tighten parts and do not force connection Use open end wrench to complete assembly Do not use any type of thread sealant as they may be flammable

4 Torch Assembly Liquid Propane Cylinder Regulator Hose Torch

5 Torch MUST have operable stand!

6 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.

7 Leak Test Kit

8 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!

9 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 Use striker to ignite gas and adjust flame NEVER USE CIGARETTE LIGHTERS OR MATCH

10 Flint Striker

11 Propane Storage

12 Always assume a torch at rest is lit Use leg stand to support torch Shut torch off when not in use Never leave torch unattended Never operate within 3 feet of other workers Never point torch towards flammable objects or areas you can not see clearly

13 Use caution when using torch around: – Roof openings, units & drains – Roofing materials and combustible deck

14 Never turn propane cylinder on its side This does not increase fuel supply and is dangerous Never apply open flame to defrost cylinders If frost is present: Reduce pressure on regulator Switch to a smaller (lower BTU) torch head Switch to a larger / manifolded tank

15 Always disconnect torches at end of work day Inspect all components for damage Replace damaged components Set torch on side and close cylinder valve Squeeze torch trigger to purge remaining gas Close all valves and disconnect torch Properly store equipment & secure cylinders
