Power tool safety

Safety is critical when using power tools, regardless of how they are powered. Carelessness or mishandling of power tools can cause serious injury. Here are some general power tool safety rules that must always be followed:

Return all equipment to its proper place when finished.

Wear eye protection.

Noise may be a hazard with some portable power tools, especially pneumatic tools. Wear hearing protection whenever noise is excessive.

Wear gloves when operating air chisels or air hammers.

All electrical equipment should be grounded, unless it is the double insulated type.

Never make adjustments, lubricate, or clean a machine while it is running.

Do not clean yourself or anyone else with compressed air.

Report any suspect or malfunctioning machinery to the instructor or service manager.

Know your power tool. Read the operator manual carefully. Learn its applications and limitations as well as the specific potential hazards peculiar to this tool. Do not operate any power tools in damp or wet locations. Keep your work area well lighted.

Do not abuse an electric power cord. Never yank it to disconnect it from a receptacle.

No machine should be started unless guards are in place and in good condition. Defective or missing guards should be reported to the instructor or service manager immediately.

Check and make all adjustments before applying power.

Give the machine your undivided attention while you are using it. Do not look away or talk to others.

Inspect all equipment for safety and for apparent defects before using.

Whenever safeguards or devices are removed to make repairs or adjustments, equipment should be turned off and the main switch locked and tagged.

Start and stop your own machine and remain with it until it has come to a complete stop.

Always allow any machine to reach operating speed before loading it.

No attempt should be made to retard rotation of the tool or work.

Do not try to strip broken belts or other debris from a pulley in motion or reach between belts and pulleys.

Do not use loose rags around operating machinery.

Use the right tool. Do not use too small a tool or attachment to do the job of a heavy-duty tool.

Maintain tools with care. Keep tools sharp and clean at all times for best and safest performance. Follow instructions for lubricating and changing accessories.

Remove adjusting keys and wrenches. Make a habit of checking that keys and adjusting wrenches are removed from chucks and tools before switching them on.

Do not overreach. Maintain a balanced stance to avoid slipping.

Disconnect tools when not in use; before servicing; or when changing attachments, blades, bits, cutters, and so on. Before plugging in any electric tool or machine, make sure the switch is off. When the task is completed, switch it off and unplug it.

Remove all sharp edges and burrs before completing any job.
