Welding and Cutting Prerequisites
Before conducting welding or cutting operations, inspect your equipment for the following:
- Welding leads must be completely insulated and in good condition.
- Cutting torches and hoses must be leak-free and equipped with proper fittings, gauges, regulators, and flashback devices.
- Oxygen and acetylene tanks must be secured in a safe place.
In addition, follow these guidelines for most welding and cutting procedures:
- Conduct welding and cutting operations in a designated area free from flammable materials. When welding or cutting is necessary in an undesignated or hazardous area, have someone nearby act as a fire attendant.
- periodically check welding and cutting areas for combustible atmospheres.
- Take care to prevent sparks from starting a fire.
- Remove unused gas cylinders from the welding and cutting area.
- Keep hoses out of doorways and away from other people. A flattened hose can cause a flashback.
- Mark hot metal with a sign or other warning when welding or cutting operations are complete.
The following table provides an overview of welding and cutting hazards:
|Potential Hazard||Hazard Source|

- Confined space
|Sparks, Fire, Explosion||
- Flammable materials
|UV radiation Burns||
- Gas arc
