What should welders with pacemakers or defibrillators do before welding?

Welders with pacemakers or defibrillators are advised to consult a physician prior to engaging in welding activities. This is crucial because welding can generate strong electromagnetic fields and electrical currents, which might interfere with the functioning of these medical devices. A physician can provide personalized advice based on the individual's specific health condition and the type of welding they will be performing. This step ensures that the welder understands any potential risks and can take appropriate precautions to maintain their safety while working.

The other options, while they may seem relevant, do not address the root of the concern. Using extra protective gear could help in certain situations, but without the guidance of a healthcare professional, it may not adequately mitigate the risks associated with electromagnetic interference. Limiting welding time may reduce exposure but does not eliminate the fundamental safety risks. Avoiding all welding activities entirely could be an extreme measure; however, it is not always necessary if the welder receives proper medical advice and recommendations tailored to their health status. Consulting a physician ensures that welders can perform their work safely without jeopardizing their health.
