Tool Safety and Inspection
Reference: A-2
All 120-volt, single-phase 15- and 20-ampere receptacle outlets on construction sites, which are not a part of
the permanent wiring of the building or structure, and which are in use by workers, shall have approved groundfault circuit interrupters for personnel protection. Receptacles on a two-wire, single-phase portable or vehiclemounted generator rated not more than 5kW, where the circuit conductors of the generator are insulated from
the generator frame and all other grounded surfaces, need not be protected with ground-fault circuit
interrupters. 1926.404(b)(1)(ii)
Powered Abrasive Wheel Tools
Powered abrasive grinding, cutting, polishing, and wire buffing wheels create special safety problems because
they may throw off flying fragments.
Before an abrasive wheel is mounted, it should be inspected closely and sound- or ring-tested to be sure that it
is free from cracks or defects. To test, wheels should be tapped gently with a light non-metallic instrument. If
they sound cracked or dead, they could fly apart in operation and so must not be used. A sound and undamaged
wheel will give a clear metallic tone or "ring."To prevent the wheel from cracking, the user should be sure it fits
freely on the spindle. The spindle nut must be tightened enough to hold the wheel in place, without distorting
the flange. Follow the manufacturer's recommendations. Care must be taken to assure that the spindle wheel
will not exceed the abrasive wheel specifications.
Due to the possibility of a wheel disintegrating (exploding) during start-up, the worker should never stand
directly in front of the wheel as it accelerates to full operating speed.
Portable grinding tools need to be equipped with safety guards to protect workers not only from the moving
wheel surface, but also from flying fragments in case of breakage.
Powered Grinder Safety Precautions

•
Always use eye protection.
Turn off the power when not in use.
Never clamp a hand-held grinder in a vise.
Pneumatic Tools
Pneumatic tools are powered by compressed air and include chippers, drills, hammers, and sanders. There are
several dangers encountered in the use of pneumatic tools. The main one is the danger of getting hit by one of
the tool's attachments or by fastener the worker is using with the tool. Eye protection is required, and face
protection is recommended for workers working with pneumatic tools. Working with noisy tools such as
jackhammers requires proper, effective use of hearing protection.
