Tools and Industrial Equipment
It is important that your power tools and/or equipment be in good working order and properly wired (three-prong plug, if applicable) and used as intended by the manufacturer of the product. It is recommended that corded electrical items be plugged into a safety outlet device called a ground fault circuit interrupter (GFCI or GFI).
No Known Risk
If the item is used as intended and in good working condition, there is no known risk:
- Calipers – battery powered
- Flashlight – battery powered
- Laser Level
- Soldering Iron
- Stud Finder
Minimal Risk
Maintain at least a 6-inch (15 cm) distance between the item and your heart device:
- Circular Saw – skill saw
- Drills – battery and electric powered
