be leak-free and equipped with proper fittings, gauges, regulators, and flashback
devices;
x
Oxygen and acetylene tanks

In addition, follow these guidelines for most welding and cutting procedures:
x
Always conduct welding and cutting operations in compliance with the requirements of the checklist
and Permit to Work;

Mark hot metal with a sign or other warning when welding or cutting operations are complete. Proper
selection of personal protective equipment is very important when welding; make sure your welding helmet
visor is dark enough to provide adequate protection. Wear fireproof apron and gloves. In addition, take care
to protect other people from the hazards of welding. For example, use a welding curtain to protect other
employees from UV radiation.
