One of the most convenient types tools for craftsmen are power tools. Electric drills and saws, to name a few, are powered with electricity, something that cannot be seen. It easy to become complacent when using these tools, that's why you must always be aware of the electrical hazards involved with their use.
A woman was helping her husband clear some small trees from their property when she tripped on some brush. When she fell, her neck touched the chainsaw her husband was operating, cutting an artery. She died from massive blood loss. The victims of chainsaw-related injuries are usually the operators, but obviously can also be a coworker, friends or family members.
Chain saws can be great labor saving tools, but if not operated properly and with respect, they can quickly cause severe injury and death. At least two people died from injuries related to chain saws during the first week of cleanup after Hurricane Hugo several years ago.
