Page 6: Gas Equipment Safety Instructions And Warnings
SECTION 1: GAS EQUIPMENT SAFETY INSTRUCTIONS AND WARNINGS The information shown under this note must be followed carefully to avoid injuring the operator or anyone in the operating area. When an accident does occur with gas equipment, it’s usually due to the operator having become careless through over-familiarity. -
Page 7: Oxygen Cylinders
1.03 Oxygen Cylinders Oxygen cylinders are steel shells of ample strength for their purpose. Besides routine inspections, they periodically undergo a searching examination, which includes a hydraulic pressure test. Always call oxygen “Oxygen” not “Air”. Never use oxygen in pneumatic tools, in oil pre-heating burners, to start engines, to blow out pipelines or to freshen the atmosphere in confined spaces. -
Page 8: Lpg Cylinders
1.05 LPG Cylinders LPG cylinders are provided with relief valves or fusible plugs to discharge their contents and keep the cylinder pressure within safe limits should the cylinder be overheated by a fire. LPG cylinders should be used and stored upright in the open, away from combustible material. -
Page 9: Flashback Arrestors
Make sure the flashback arrestors you use now have this labelled on them. Testing AS 4289-1995 states flashback arrestors shall be tested annually, this can be done by one of CIGWELD’s extensive network of accredited service agents. Flashback arrestors should also be tested if they have been subjected to backfiring and flashbacks. - Page 10 Further, non-interchangeability of hose fittings is maintained by using a right hand (RH) thread for Oxygen and a left hand (LH) thread for fuel. CIGWELD’s COMET hose fittings fulfil all of these important requirements. Dimensions for hose fitting connector nuts and nipples are given in AS 4267.

Page 14: After Completion Of Use (Shut-Down)
IMPORTANT: This test should be done quickly, and it is important that there are no sources of ignition present during this process, as a certain amount gas will be released to the atmosphere. If no leaks are detected, the system is ready for use. In an Oxy/Fuel system, particular care needs to be taken to ensure that gasses are not mixed, as this may lead to flashback upon lighting up. -
