Tool Safety and Inspection
Reference: A-2
The following hand-held powered tools may be equipped with only a positive "on-off" control switch: platen
sanders, disc sanders with discs two inches or less in diameter; grinders with wheels two inches or less in
diameter; routers, planers, laminate trimmers, nibblers, shears, scroll saws and jigsaws with blade shanks ¼inch wide or less.
Other hand-held powered tools such as circular saws having a blade diameter greater than two inches, chain
saws, and percussion tools without positive accessory holding means must be equipped with a constant
pressure switch that will shut off the power when the pressure is released.
Electrical Safety
Among the chief hazards of electric-powered tools are burns and slight shocks which can lead to injuries or even
heart failure. Under certain conditions, even a small amount of current can result in severe injury and eventual
death. A shock also can cause the user to fall off a ladder or other elevated work surface.
To protect the user from shock, tools must either have a three-wire cord with ground or be grounded, be double
insulated, or be powered by a low-voltage isolation transformer. Three-wire cords contain two current-carrying
conductors and a grounding conductor. One end of the grounding conductor connects to the tool's metal
housing. The other end is grounded through a prong on the plug. Anytime an adapter is used to accommodate
a two-hole receptacle, the adapter wire must be attached to a known ground. The third prong should never be
removed from the plug.
Double insulation is more convenient. The user and the tools are protected in two ways: by normal insulation
on the wires inside, and by a housing that cannot conduct electricity to the operator in the event of a
malfunction.
Electric Power Tool General Safety Practices
•
•
•
•
•
Electric tools should be operated within their design limitations.
Gloves and safety footwear are recommended during use of electric tools.
When not in use, tools should be stored in a dry place.
Electric tools should not be used in damp or wet locations.
Work areas should be well lighted.
Ground Fault Protection
The Company shall use either ground fault circuit interrupters or an assured equipment grounding conductor to
protect workers on construction sites. These requirements are in addition to any other requirements for
equipment grounding conductors.
