Tool Selection
Non-Powered
 Electric
 Air Powered
 Powder Actuated
 Gas Powered

Safety Note: If you have to modify a
tool to make it work, you probably
don’t have the right one!
Non-Powered Hand Tools



Impact tools such as
chisels, wedges, or drift
pins are unsafe if they
have mushroomed heads.
Wrenches with sprung
jaws should be taken out
of service.
Wooden handled tools
should be inspected
periodically to make sure
they are not splintered,
cracked, or loose.
Electric Tools




Electric tools are difficult
to guard completely
They are subject to more
abuse than stationary
tools
Cords must be inspected
regularly
These tools should be
unplugged/battery
removed for all
maintenance procedures.
Double Insulated Tools



NFPA 70 permits double
insulation for portable
tools
Third wire grounding is
not necessary for
double-insulated tools
Double insulation works
by isolating the tool’s
internal electric
components from the
outer housing
Circular Saw Safety Tips




Set the blade’s depth to
no more than 1/8” to ¼”
greater than the
thickness of the material
Avoid binding the blade
and causing a “kickback”
Release the trigger if the
saw binds or stalls
Never pull the saw out of
a cut until the blade stops
Pneumatic Tools
(Nail Guns)





Make sure the nose guard safety
spring is functioning properly
Don’t hook up the power source
until it is time to nail
If the tool has to be carried while
under power, stay away from the
trigger and never carry against
the body
Safety glasses are a must!
For Framers;




Keep the off hand out of the way
Never nail beyond your reach
Keep the gun properly aligned
with the work
Be aware of surroundings and
fellow workers
Powder-Actuated Tools






Only employees who have
been trained and certified in
the operation of the
particular tool shall be
allowed to operate
Must be tested each day prior
to use
If it doesn’t pass inspection,
it must be removed from
service
All required PPE must be
worn
Unfired caps should not be
left in the gun or lying around
The loaded tool should never
be left unattended
Gas Powered Tools



Types include leaf blowers,
trimmers, mowers, and
chainsaws.
Follow manufacturers
recommendations for service
intervals and safe use.
Take special care during
refueling.
