Most of us use power tools every day. Generally, we don't get hurt. Working with power tools, you can get an electric shock, lose a finger, lose an eye, or go deaf. It's especially dangerous to use a tool that's defective, that's been modified, or that's not designed for the job. Of course, you can also get injured if you use any tool carelessly.

1. We use many kinds of power tools in construction. They may be air-powered, gasoline-powered, electric, or hydraulic. What do you think are the most common injuries from working with these tools?
  • Electric shock
  • Falling
  • Hearing loss
  • Ergonomic injuries
  • Flash burns
  • Eye injuries
  • Crushing or losing a body part
2. What safety rules should you keep in mind when you use portable power tools?
  • Use the right tool for the job. Never use a tool for a job it wasn't designed to do. Make sure you're familiar with your tools and know-how to use them properly.
  • Select tools that fit the hand comfortably, have soft grips that don't cut into your hand and are not too heavy.
  • Select tools with reduced vibration and noise levels.
  • Keep secure footing and balance when you use tools. The area where you're standing shouldn't be slippery or cluttered.
  • Use tools on a stable work surface. Hold the work with a vise or clamps if necessary.
  • Use tools in a well-lighted area.
  • Avoid awkward positions when using power tools. Some tools are poorly designed and force you to work with unnecessary strain on your wrist, arm, shoulder, or back. Use tools with a better design.
  • Make sure you have enough workspace to work, and can keep your body at a comfortable angle to the work. Adjust the position of the tool, or the orientation of the work surface, to minimize bending your wrist or body, reaching, or twisting.
  • Keep tools where they belong. Never leave them on a ladder, scaffold, or overhead workspace. Keep them where they won't fall on someone or trip someone.
  • Don't use powder-actuated tools unless you have a valid operator's card for the specific tool involved. You need special training.
3. How do you make sure your power tools stay in a safe condition?
  • Keep tools clean. Inspect them every day. Check blades, bits, and other cutting parts prior to each use. Make sure they are sharp, and not worn or cracked. Check chucks, collars, and other tool holding parts to make sure they are in good operating condition. Tag tools and take them out of service if there's a problem.
  • Make sure tools have guards on their blades, bits, rollers, chains, gears, sprockets, and other dangerous moving parts.
  • Never remove guards. Don't tie them back or modify them either.
4. What can you do to avoid shocks from electric power tools?
  • Make sure tools have a 3-wire cord and are grounded. (Double-insulated tools don't need a ground.)
  • Don't remove the third prong (the ground prong) from a plug. If you use an adapter (3- prong plug to 2-hole outlet), make sure it's grounded.
  • Check power tools and cords daily for cracks, exposed wire, and breaks in the insulation.
  • If a tool buzzes, report it immediately and have an electrician check it out. Either the wiring or the tool itself may be defective.
  • Don't use ordinary household extension cords. Use 3-wire cords intended for heavy-duty. Don't run them near water, other liquids, or metal which can carry current.
  • Don't touch any electrical equipment when the equipment is wet, you're wet, you're sweating, or you're standing on a wet surface.
