Subpart I_Tools_Hand and Power
Sec. 1926.302 Power-operated hand tools.
(a) Electric power-operated tools. (1) Electric power operated tools
shall either be of the approved double-insulated type or grounded in
accordance with subpart K of this part.
(2) The use of electric cords for hoisting or lowering tools shall
not be permitted.
(b) Pneumatic power tools. (1) Pneumatic power tools shall be
secured to the hose or whip by some positive means to prevent the tool
from becoming accidentally disconnected.
(2) Safety clips or retainers shall be securely installed and
maintained on pneumatic impact (percussion) tools to prevent attachments
from being accidentally expelled.
(3) All pneumatically driven nailers, staplers, and other similar
equipment provided with automatic fastener feed, which operate at more
than 100 p.s.i. pressure at the tool shall have a safety
[[Page 228]]
device on the muzzle to prevent the tool from ejecting fasteners, unless
the muzzle is in contact with the work surface.
(4) Compressed air shall not be used for cleaning purposes except
where reduced to less than 30 p.s.i. and then only with effective chip
guarding and personal protective equipment which meets the requirements
of subpart E of this part. The 30 p.s.i. requirement does not apply for
concrete form, mill scale and similar cleaning purposes.
(5) The manufacturer's safe operating pressure for hoses, pipes,
valves, filters, and other fittings shall not be exceeded,
(6) The use of hoses for hoisting or lowering tools shall not be
permitted.
(7) All hoses exceeding \1/2\-inch inside diameter shall have a
safety device at the source of supply or branch line to reduce pressure
in case of hose failure.
(8) Airless spray guns of the type which atomize paints and fluids
at high pressures (1,000 pounds or more per square inch) shall be
equipped with automatic or visible manual safety devices which will
prevent pulling of the trigger to prevent release of the paint or fluid
until the safety device is manually released.
(9) In lieu of the above, a diffuser nut which will prevent high
pressure, high velocity release, while the nozzle tip is removed, plus a
nozzle tip guard which will prevent the tip from coming into contact
with the operator, or other equivalent protection, shall be provided.
(10) Abrasive blast cleaning nozzles. The blast cleaning nozzles
shall be equipped with an operating valve which must be held open
manually. A support shall be provided on which the nozzle may be mounted
when it is not in use.
(c) Fuel powered tools. (1) All fuel powered tools shall be stopped
while being refueled, serviced, or maintained, and fuel shall be
transported, handled, and stored in accordance with subpart F of this
part.
(2) When fuel powered tools are used in enclosed spaces, the
applicable requirements for concentrations of toxic gases and use of
personal protective equipment, as outlined in subparts D and E of this
part, shall apply.
(d) Hydraulic power tools. (1) The fluid used in hydraulic powered
tools shall be fire-resistant fluids approved under Schedule 30 of the
U.S. Bureau of Mines, Department of the Interior, and shall retain its
operating characteristics at the most extreme temperatures to which it
will be exposed.
(2) The manufacturer's safe operating pressures for hoses, valves,
pipes, filters, and other fittings shall not be exceeded.
(e) Powder-actuated tools. (1) Only employees who have been trained
in the operation of the particular tool in use shall be allowed to
operate a powder-actuated tool.
(2) The tool shall be tested each day before loading to see that
safety devices are in proper working condition. The method of testing
shall be in accordance with the manufacturer's recommended procedure.
(3) Any tool found not in proper working order, or that develops a
defect during use, shall be immediately removed from service and not
used until properly repaired.
(4) Personal protective equipment shall be in accordance with
subpart E of this part.
(5) Tools shall not be loaded until just prior to the intended
firing time. Neither loaded nor empty tools are to be pointed at any
employees. Hands shall be kept clear of the open barrel end.
(6) Loaded tools shall not be left unattended.
(7) Fasteners shall not be driven into very hard or brittle
materials including, but not limited to, cast iron, glazed tile,
surface-hardened steel, glass block, live rock, face brick, or hollow
tile.
(8) Driving into materials easily penetrated shall be avoided unless
such materials are backed by a substance that will prevent the pin or
fastener from passing completely through and creating a flying missile
hazard on the other side.
(9) No fastener shall be driven into a spalled area caused by an
unsatisfactory fastening.
(10) Tools shall not be used in an explosive or flammable
atmosphere.
[[Page 229]]
(11) All tools shall be used with the correct shield, guard, or
attachment recommended by the manufacturer.
(12) Powder-actuated tools used by employees shall meet all other
applicable requirements of American National Standards Institute, A10.3-
1970, Safety Requirements for Explosive-Actuated Fastening Tools.
