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
1.07 Flashback Arrestors A flashback occurs when mixed gases within a cutting and welding blowpipe system ignite and, due to several possible reasons burn back through the system against the flow of gas. The consequences of a flashback range from sooting of the hose, to serious equipment fires and possible explosion. -
Page 10: Electrical System
Pressure Drop Pressure drop simply means that for gas to flow through the hose, for a given pressure at the beginning of the hose (eg. at the regulator), the pressure at the other end of the hose (eg. at the blowpipe) will be less. For a given flow and length of hose, the pressure drop in a small bore hose, will be greater than in a larger bore hose. -

Page 13: Testing For Leaks Before Use
The machine case is made mainly from aluminium alloy for lightness, so can be damaged by shocks and impacts. Therefore, take care not to let heavy objects fall on the machine and do not drop the machine when moving it. ... -
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. -
