TOOLBOX TALK 53/60
TOPIC: CUTTING AND WELDING
OBJECTIVE: TO ENSURE SAFE CUTTING AND WELDING (FIRE PREVENTION)
Here are a few simple precautions to take to prevent cutting and welding accidents:
- Never weld or cut a drum, tank or pipe unless you are absolutely sure it is clear of any flammable materials.
- Use the minimum gas pressure needed for cutting in order to reduce slag and sparks.
- Use protective material to catch slag or sparks where they may fall onto materials that may catch fire.
- Have a fire extinguisher nearby.
- Never oil the control regulators. Oil will spontaneously ignite in the presence of oxygen.
- Follow all ‘permit’ requirements of the plant owner or your own company policies.
- Never leave a torch in a storage container overnight without turning the oxygen and acetylene off the bottle. A leaking torch creates a very serious explosion potential.
- If sparks can fall into combustible material, be sure to check closely for a smouldering fire before leaving the area.
- Check the area again after about half-an-hour to make sure there is not a smouldering fire.
- Use a checklist to make sure equipment is in good working order.
Try this for show and tell!
- Review the welding and cutting fire prevention steps (obtaining permit, fire extinguisher and blankets, fire watch, later check for smouldering materials).
Questions you can use to get your team talking:
- What work do we do where there is real danger or fire or explosions caused from cutting torches or welding?
- Do you have any suggestions for preventing these types of accidents?
- What fires have you heard of that were started by cutting and welding?
