This document provides guidance on safely operating hand and power tools. It outlines key safety practices such as regularly inspecting tools, using proper personal protective equipment, ensuring all guards are in place, following manufacturer instructions, and recognizing hazards. Tragedies can be avoided by being trained on tools, identifying risks, and understanding necessary precautions.

IntroductionIntroduction
There is no doubt that tools, both hand
and powered, enable us to be more
efficient and productive. Unfortunately,
the power and efficiency of tools can also
pose a serious risk of injury or death.
Too often, tragedy occurs before steps
are taken to search out and avoid or
eliminate tool-related hazards.

Your employer is responsible for ensuring the
tools they supply employees are the right tools
for the job and are safe to use. You must ensure
that they stay that way.

PPEPPE
Personal protective equipment is a must
when you work with tools. According to
OSHA’S requirements PPE must be
provided, used, and maintained in a
sanitary and reliable condition at all times.
Here are some common types of PPE:
 Safety glasses.
 Face shield.
 Gloves.
Hard hat.
Respirator.
Hearing protection.
Foot protection.

Non powered toolsNon powered tools
Non powered tools include anything from
axes to wrenches. Many injuries that occur
when using hand tools are due to:
Repetitive motion.
Failure to wear PPE.
Being cut or struck by the tool.
Inspect tools with wooden handles for cracks and
splinters and keep cutting tools sharp.

DO
• Wear safety glasses or a faceshield.
• Use the tools only if they are good condition (i.e., cutting edges are sharp,
struck head is not mushroomed or chipped).
• Hold the chisel, for shearing and chipping, at an angle which permits the
bevel of the cutting edge to lie flat against the shearing plane.
• Provide hand protection

Chisel Safety Don'tsChisel Safety Don'ts
 Do not use stuck tools if the struck end is chipped or
mushroomed.
 Do not use stuck tools if the cutting edge is dull or chipped
or if the point of a punch is slanted or damaged.
 Do not apply too much pressure to the head when grinding a
chisel. The heat generated can remove the temper. Immerse
the chisel in cold water periodically when grinding.
 Do not use cold chisels for cutting or splitting stone or
concrete.
 Do not use a drift pin punch (also called an aligning punch)
as a pin punch intended for driving, removing, or loosening
pins, keys, and rivets.
 Do not allow bull point chisels to be hand-held by one
employee and struck by another. Use tongs or a chisel holder
to guide the chisel so that the holder's hand will not be
injured.

Power toolsPower tools
There are several types of power tools,
based on the power source they use
including:
Electric
Pneumatic
Liquid fuel
Hydraulic and power actuated.
Observe the following general precautions when you use
a power tool:

12. 11/12/15Hand & Powertool

Power tools cont.Power tools cont.
Never carry a tool by the cord or hose.
Never yank the cord or the hose to disconnect it.
Keep cords and hoses away from heat, oil, and
sharp edges.
Disconnect tools when not in use, before
servicing , and when changing accessories such
as blades, bits, and cutters.
Keep observers at a safe distance from the work
area.
Avoid accidental starting. Do not hold your
finger on the switch button while carrying a
plugged-in tool.

 Keep tools sharp and clean for the best performance.
Follow instructions in the user’s manual for
lubrication and changing accessories.
 Keep good footing and maintain good balance when
using tools.
 Secure work with clamps or a vise, freeing both hands
to operate the tool.
 Wear the proper apparel. Loose clothing, ties or
jewelry can become caught in moving parts.
 All portable electric tools that are damaged must be
removed from service and tagged “Do not use”“Do not use”

Portable Abrasive
Wheel Tools

15. 11/12/15Hand & Powertool

Portable abrasive grinding, cutting, polishing, and wire buffing
wheels create special safety problems because they may
throw off flying fragments. Abrasive wheel tools must be
equipped with guards that: (1) cover the spindle end, nut, and
flange projections; (2) maintain proper alignment with the
wheel; and (3) do not exceed the strength of the fastenings.
Before an abrasive wheel is mounted, it must be inspected
closely for damage and should be sound- or ring-tested to
ensure that it is free from cracks or defects. To test, wheels
should be tapped gently with a light, non-metallic instrument. If
the wheels sound cracked or dead, they must not be used
because they could fly apart in operation. A stable and
undamaged wheel, when tapped, will give a clear metallic
tone or "ring."
To prevent an abrasive wheel from cracking, it must fit freely
on the spindle. The spindle nut must be tightened enough to
hold the wheel in place without distorting the flange. Always
follow the manufacturer's recommendations.

An abrasive wheel may disintegrate or explode during
start-up. Allow the tool to come up to operating speed
prior to grinding or cutting. The employee should never
stand in the plane of rotation 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 wheel breakage.
 Always use eye or face protection.
 Turn off the power when not in use.
 Never clamp a hand-held grinder in a vise.

SummarySummary
Hazards are usually the result of
improper tool use or not following one
or more of these protection techniques:
 Inspecting the tool before each use.
 Using PPE ( Personal Protective equipment)
 Using guards.
 Properly storing the tool.
 Using safe handling techniques or
manufacturer’s instructions.
