Pacemakers today are designed to interrupt lives as little as possible. Farmers returning to work with a pacemaker can raise some concerns. Minimal restrictions are required in the work place, but several modifications may be necessary to the way tasks are performed.

The decision to use certain tools requires the consultation of a heart doctor. The doctor can provide information about the degree of risk these tools pose as a medical threat. It is highly important to inform the doctor of any potentially dangerous situations that may be encountered with the pacemaker. Pacemakers do differ and one device may be more appropriate for the person's occupation than another device.

Recommended Safety Precautions for Tools and Equipment

It is recommended to use a soldering iron instead of a soldering gun. A soldering gun generates an electromagnetic spike when the button is released, which can be a problem for electromagnetically sensitive devices. If a soldering gun is used it needs to stay at least six inches away from the pacemaker.

Turn the engine off before working on any gas-powered tools or equipment. Caution needs to be taken when standing/leaning near the coil, distributor, or spark plugs of a equipment. Do not work on the distributor with the engine running.

Power tools can still be used, but they need to be kept away from the pacemaker. The tools should be inspected before each use to ensure they are not damaged and are not likely to cause electric shock. People with pacemakers should never work alone and should always properly ground all tools before use because pacemaker recipients are more susceptible to electric shock.

Recommended Safety Precautions When Welding

It is recommended that people with pacemakers avoid welding; however, some individuals may still need to use these tools. People with pacemakers using welding equipment should use extreme caution.

  • Do not use current settings higher than necessary. It is suggested to not use more than 130 ampere range.
  • Ensure the area is dry.
  • It is important to wear dry gloves and shoes.
  • Keep the weld cables as close together as possible by twisting or taping them.
  • Connect work clamp to workpiece as close to the weld as possible.
  • Arrange cables to one side and away from the operator.
  • Keep welding power source and cables as far away as practical.
  • Keep the welding arc 2 feet from the pacemaker.
  • Do not weld with rapidly repeated short spurts—wait about 10 seconds between each weld.
  • If you feel sick, such as light headed or dizzy, stop welding immediately and get medical attention.
  • Again, do not work alone.

Recommended Safety Precautions for Chain Saw

There are also certain precautions when using a chain saw. Caution needs to be used with chain saws because unlike most power tools, they have a tendency to temporarily affect the pacemaker. An electric chainsaw is safer than one that is gas powered. With gas-powered chainsaws the hands and body come into close contact with the electric spark generating components that could interact with the pacemaker.

The Precautions Are:

  • The motor of an electric chain saw should be held 6 inches from the pacemaker.
  • If using a gas-powered chain saw is absolutely necessary, the ignition system should never be within 12 inches of the pacemaker. Choose a machine where the spark plug is not near the handgrips.
  • If you feel sick, such as light headed or dizzy, immediately discontinue use and get medical attention.
