Welding and cutting are two forms of hot work that require special safety considerations. Unless they are done in a designated shop area, welding and cutting are strictly prohibited without proper authorization, Hot Work Permit.

Before conducting welding or cutting operations, inspect your equipment for the following:

• Welding leads must be completely insulated and in good condition.
• Cutting tools 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.
