What are some general OSHA guidelines to use when using power (electric) tools or other hand tools in the workplace?

Accepted Answer

Some general OSHA guidelines for using power tools or other hand tools in the workplace are as follows:
*Wear personal protective equipment (PPE) to protect yourself as you work. For example, wear eye protection where dust or fumes are generated by power tools.
*Keep all tools in good condition and properly store tools not in use. Examine a tool for damage before you use it.
*Use the right tool for the job and operate the tool according to the manufacturer's instructions and guidelines. Don't work with a tool unless you are trained and authorized to use it.
*Watch out for trip hazards, so you and others don't stumble on a tool or cord. For example, keep power tool electrical extension cords out from underfoot, and don't leave hand tools lying around unattended.
