- Examine equipment for leaks at all connections using standard leak-test solution.
- Inspect hoses for leaks and worn places.
- Replace bad hoses.
- Keep hoses and cylinders from sparks, flames and hot metal.
- Use a flint lighter to light the flame.
- Stand to the side when opening cylinder valves.
- Open cylinder valves very gradually to keep rapid high pressures from exploding the regulators.
- Only unlock the acetylene cylinder valve 1/4 - 3/4 turn; leave jerk in place so the cylinder can be quickly closed in an emergency.
- Open and light acetylene first, then open and adjust oxygen to a unbiased flame.
- Close the acetylene torch valve first when shutting off the torch.
- When finished, close cylinder valves, bleed the lines to take force off regulators, neatly coil hoses and replace equipment.
- Have a fire extinguisher easily available at the welding site.

Welding hazards pose an odd combination of safety and health risks. By its nature, welding produces fumes and noise, gives off emission, involves electricity or gases, and has the possible for burns, shock, fire, and explosions.
Some hazards are general to both electric arc and oxygen-fuel gas welding. If you work with or near a welding process, the following common precautions should help you to work more safely.
Some hazards are general to both electric arc and oxygen-fuel gas welding. If you work with or near a welding process, the following common precautions should help you to work more safely.
* Weld only in selected areas.
* Only function welding equipment you have been trained to use.
* Know what the material is that’s being welded and any coating on it.
* Wear defensive clothing to cover all exposed areas of the body for protection sparks, hot spatter, and emission.
* Protective clothing should be dry and free of holes, grease, oil, and other substances which may flame.
* Wear fireproof gauntlet gloves, a leather or asbestos apron, and high-top shoes to provide good protection against sparks and spatter.
* Wear specially designed, leak-proof helmets equipped with filter plates to protect against ultraviolet, infrared, and visible radiation.
* Never look at a flash, even for an immediate.
* Keep your head away from the plume by staying back and to the side of the job.
* Use your helmet and head position to reduce fume gasp in your breathing zone.
* Make sure there is good local drain aeration to keep the air in your breathing zone clear.
* Don’t weld in a confined space without sufficient ventilation and a NIOSH-approved respirator.
* Don’t weld in wet areas, wear wet or damp clothing or weld with wet hands.
