The passage provides important safety guidelines to minimize exposure to electromagnetic fields (EMF) generated during welding operations. Here’s a breakdown of the key points:

1. EMF Generation by Welding Current:
   • Electric current flowing through a conductor creates localized electric and magnetic fields (EMF).
   • Welding current, specifically, generates EMF fields around welding cables and machines.
2. Health Considerations:
   • Pacemaker Interference: EMF fields can interfere with some pacemakers. Welders with pacemakers should consult their physicians before welding.
   • Unknown Health Effects: There may be other health effects from EMF exposure during welding that are not yet known.
3. Procedures to Minimize EMF Exposure:
   • Cable Management:
     • Route the electrode and work cables together and secure them with tape when possible.
     • Never coil the electrode lead around your body.
   • Body Positioning:
     • Avoid placing your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side.
   • Work Cable Connection:
     • Connect the work cable to the workpiece as close as possible to the welding area.
   • Proximity to Power Source:
     • Avoid working next to the welding power source.

By following these guidelines, welders can reduce their exposure to potentially harmful EMF fields.
