This image outlines important Safety Precautions for using the welding, cutting, and heating plant. Here are the precautions listed:

1. Check "O" rings regularly and replace if worn or damaged.
2. Do not allow oil or grease to come into contact with the equipment. Oxygen can react explosively with oil or grease.
3. Do not remove regulators from cylinder valves and blowpipe from hoses without first closing cylinder valves and releasing the gas from the regulator, blowpipe and hoses.
4. Do not use regulator as a control valve. When plant is not in use for an extended period of time (overnight), close cylinder valves on the cylinders and release the pressure from the blowpipes, regulators and hoses.
5. Do not use the Comet 3 equipment with any gas other than that for which it was designed.
6. After making any repairs or service requirements to the equipment always test to ensure correct operation.
7. Open cylinder valve slowly.
8. Ensure all connections are leak-free. Never test for leaks with flame.
9. If a flashback occurs immediately turn off the blowpipe oxygen valve. Then the fuel gas valve. Allow the blowpipe and tip or nozzle to cool and purge gases before relighting. If flashback persists shut down equipment and consult your CIG service centre.
