Injury Statistics
• Nearly 12% of all onthe-job injuries involve
hands and fingers
• Injuries to fingers and
thumb rank as the 3rd
most frequently injured
body parts
• The majority of these
injuries could have been
prevented
Three Types of Injuries
• Traumatic:
– Lacerations, punctures, fractures, amputations
• Repetitive Motion:
– Doing certain tasks over and over again
– Cumulative trauma
• Contact:
– Thermal, chemical
Traumatic Injuries
Traumatic/Repetitive Motion
• Most common types
• Generally result from improper use of tools or
from inadequate guarding of machines
• Traumatic injury results from a sudden,
unexpected incident but repetitive motion injury
results from lifetime of misuse
• Both are easily preventable if proper precautions
are taken
Hand Tools
• A good set of tools is one of the most important
safety devices we use
– Take the place of our hands
– Do jobs our hands cannot do
– Keep our hands from getting hurt
• Tool must be right for the job
Makeshift Tools
• Tool not suited for the job
– Use pliers instead of a wrench to loosen or tighten
pipe fittings
– Use a knife as a screwdriver
– Using a shovel as a pry bar
• Improper tools can cause workers to
–
–
–
–
Slip or fall
Gouge themselves
Pinch their hands
Suffer other kinds of injuries
Hand Tool Safety
• Greatest hazard comes from misuse and poor
maintenance
• All tools should be inspected prior to use
• Use tools only for their designated purpose
• Important to select right size AND type of tool for
the job
Symptoms of the Wrong Tool
•
•
•
•
•
•
•
•
•
Tingling
Swelling in the joints
Decreased ability to move
Decreased grip strength
Pain from movement, pressure, or exposure to cold
or vibration
Continual muscle fatigue
Sore muscles
Numbness
Change in the skin color of your hands or fingertips
Selecting Hand Tools
• Choosing the right tool will
help prevent traumatic
and repetitive motion
injuries
• Consider size, shape, grip
– Handles without sharp
edges, have a non-slip
surface, and are coated
with a soft material
– Angled tools help keep wrist
straight
Selecting Hand Tools
• Tools that can work in
either hand are best
• Use proper tool for the
area
– Spark resistant tool
around flammable
liquids
• Consider quality as well
The Best Tool in General
• Fits the job you are doing
• Fits the work space available
• Reduces the force you need to apply
• Fits your hand
• Can be used in a comfortable work position
Using Hand Tools
• If possible, secure all work
with a vise or a clamp
• Always wear appropriate
PPE for the job
• Don’t work with oily or
greasy hands
Using Hand Tools
• Maintain sharpness of all cutting tools
– Duller does NOT mean safer
– Sharper does NOT mean dangerous
• Remove damaged tools from service to prevent
others from accidentally using them
• After using a tool, clean it and put it back in its
proper location
Using Hand Tools
• Do not hoist or lower portable electric hand tools
by their power cords; use a rope
• If you carry sharp tools, keep the edges pointed
away from yourself and others
• Do not use “extenders” on hand tools
• When using a wrench, pull it toward you
• Avoid striking tempered steel tools together
Machine Guarding
• Another way to prevent hand injuries is with
guards and barriers that keep the hands (and
other body parts) from coming into contact with
dangerous hazards
• OSHA has some strong language with respect to
machine guarding
OSHA
One or more methods of machine guarding shall
be provided to protect the operator and other
employees in the machine area from hazards
such as those created by point of operation,
ingoing nip points, rotating parts, flying chips and
sparks. Examples of guarding methods are-barrier
guards, two-hand tripping devices, electronic
safety devices, etc.
OSHA
Guards shall be affixed to the machine where
possible and secured elsewhere if for any reason
attachment to the machine is not possible. The
guard shall be such that it does not offer an
accident hazard in itself.
OSHA
The point of operation of machines (where work
is actually performed on material) whose
operation exposes an employee to injury, shall be
guarded. The guarding device shall . . . be so
designed and constructed as to prevent the
operator from having any part of his body in the
danger zone during the operating cycle.
OSHA
Special hand tools for placing and removing
material shall be such as to permit easy handling
of material without the operator placing a hand
in the danger zone. Such tools shall not be in lieu
of guarding but can only be used to supplement
protection provided.
Special Hand Tools
When it becomes necessary for hands to be in close
proximity to the point of operation, the push stick or
block may provide a few inches of safety and prevent
a severe injury.
OSHA
When the periphery of the blades of a fan is less
than seven (7) feet above the floor or working level,
the blades shall be guarded. The guard shall have
openings no larger than one-half (1/2) inch.
Machine Safety
• Most dangerous area
is point of operation
• Point of Operation is
area where work is
done
– Cutting, punching,
drilling, etc.
• All machines should
be guarded to
prevent accidental
contact
Machine Guarding
• Guards are there to
protect employees
• Should not create
additional hazards or
interfere with
machine operation
• Can guard by
creating a physical
barrier or by creating
distance
Machine Guarding
• Guard should never be removed while machine is
operating
• Only qualified personnel should ever remove
guards
• These personnel should be trained in proper
lockout/tagout procedure
• Anytime a guard is removed, must use proper
lockout/tagout procedure
Art or Science?
• Sometimes employees remove a guard because
they say the guard interferes with their ability to
do the job
• The correct approach is to design a better guard
• Never remove or bypass a guard
• Otherwise run risk of injury and OSHA fines
Machine Guarding
Minimum General Requirements
Prevent Contact
• The safeguard must prevent hands, arms, and any
other part of a worker's body from making
contact with dangerous moving parts.
• A good safeguarding system eliminates the
possibility of the operator or another worker
placing parts of their bodies near hazardous
moving parts.
Secure
• Workers should not be able to easily remove or
tamper with the safeguard, because a safeguard
that can easily be made ineffective is no
safeguard at all.
• Guards and safety devices should be made of
durable material that will withstand the
conditions of normal use. They must firmly be
secured to the machine.
Protect From Falling Objects
• The safeguard should ensure that no objects can
fall into moving parts.
• A small tool which is dropped into a cycling
machine could easily become a projectile that
could strike and injure someone.
Create No New Hazards
• A safeguard defeats its own purpose if it creates
a hazard of its own such as a shear point, a
jagged edge, or an unfinished surface which can
cause a laceration.
• The edges of guards for instance, should be rolled
or bolted in such a way that they eliminate sharp
edges.
Create No Interference
• Any safeguard which impedes a worker from
performing the job quickly and comfortably might
soon be overridden or disregarded.
• Proper safeguarding can actually enhance
efficiency as it can relieve the worker's
apprehensions about injury.
Allow Safe Lubrication
• Any safeguard which impedes a worker from
performing the job quickly and comfortably might
soon be overridden or disregarded.
• Proper safeguarding can actually enhance
efficiency as it can relieve the worker's
apprehensions about injury.
OEM Guards
• They usually conform to the design and function
of the machine.
• They can be designed to strengthen the machine
in some way or to serve some additional
functional purposes.
User-Built Guards
• Often, with older machinery, they are the only
practical safeguarding solution.
• They can be designed and built to fit unique and
even changing situations.
• Design and installation of machine safeguards by
plant personnel can help to promote safety
consciousness in the workplace.
Training

•
A description and identification of the hazards
associated with particular machines;
The safeguards themselves, how they provide
protection, and the hazards for which they are
intended;
How to use the safeguards and why;
Training (Cont.)
• How and under what circumstances safeguards
can be removed, and by whom (in most cases,
repair or maintenance personnel only); and
• When a lockout/tagout program is required.
• What to do (e.g., contact the supervisor) if a
safeguard is damaged, missing, or unable to
provide adequate protection.
Contact Injuries
• Less common but can
be just as severe
• Never touch an object
to determine if it is
hot/cold
• Know what surfaces or
objects could be
hot/cold that are in
your work
environment
Contact Injuries
• Always where proper PPE for job at hand
• Long sleeves can help prevent contact injuries
with sharp edges or hot/cold surfaces
• If working with chemicals, consult MSDS to
familiarize yourself with all hazards associated
with that chemical
• Never use a chemical unless you are familiar with
all the hazards
5 Reasons Hands Get in Trouble
•
•
•
•
•
“I was in a hurry”
“I forgot”
“I was distracted”
“It can’t happen to me”
“I just had to touch it to see if it was (hot, sharp,
working”
Key Points
• A severe hand injury will change your quality of
life forever
• Hand injuries are preventable as long as proper
safety precautions are taken
• Always use right tool for the job and never use a
tool for anything other than its intended purpose
• Recognize when a machine should be guarded
and never use a machine if the guard has been
removed
• Don’t let a moment of carelessness lead to a
lifetime of regret!
