UNSAFE OR FAULTY TOOLS
Different Hand Tools has a variety of non-powered devices such as
pliers, hammers, and screwdrivers. These tools may seem harmless, but
using unsafe or faulty tools may cause many injuries especially in the
beginners.
The Following are some of the safety practices related to hand tools.
General hazards:
The two most common hazards associated with the use of Hand Tools are
misuse and improper maintenance.



Misuse occurs when a hand tool is used for something other than its
intended purpose. (An example would be using a screwdriver as a chisel.
This may cause the tip to break and strike someone).
Improper maintenance allows hand tools to deteriorate into an unsafe
condition. (Example would include cracked wooden handles that allow the
tool head to fly off or mushroomed heads that can shatter upon impact.
Specially designed tools may be needed in hazardous environments.
(Always use non-sparking tools in the presence of flammable vapors and
dust. Insulated tools with appropriate ratings must be used for electrical
work).
10
THE FOLLOWING ARE SOME OF THE BEST PRACTICES IN USING
SAFE TOOLS.
Pliers:





Never use pliers as a hammer on the handle. Such abuse is likely
to result in cracks or breaks.
Cut hardened wire only with pliers designed for that purpose.
Always cut a right angle. Never rock from side to side or bend the
wire back and forth against the cutting edges.
Do not increase the handle length of pliers to gain more leverage.
Use a larger pair of pliers or bolt cutters.
Do not substitute pliers for a wrench when turning bolts and nuts.
Pliers cannot grip these items properly and will slip.
Screwdrivers:
 Never use screwdrivers as a pry bar, chisel, and punch stirrer or
scraper.
 Always use a screwdriver tip that properly fits the slot of the screw.
 Keep away screwdrivers with broken or worn handles.
 Use magnetic or screw-holding screwdrivers to start fasteners in
tight areas.
 Never use pliers on a screwdriver for extra leverage. Only use
wrench or screwdrivers specifically designed to accept them.
Utility Knives/ Blades:
 Always use a sharp blade. Dull blades require more force and thus
are more likely to slip. Replace the blade when it starts to "tear"
instead of cut.
 Never leave a knife unattended with the blade exposed. Consider
using a self-retracted knife with a spring-loaded black. (The blade
will retract when pressure as the knife is released.
 Keep your free hand away from the line of the cut.
 Don't bend or apply side loads to blades by using them to open
cans or pay loose objects. Blades are brittle and can snap easily.
11
What's More
Directions: Identify the following dos and don'ts in using hand tools. Write
DO if the statement is correct and DON'T if it's not.
1. Always use a sharp blade.
2. Cut hardened wire only with pliers designed for that
purpose.
3. Use screwdrivers as a pry bar, chisel, and punch stirrer or
scraper.
4. Throw away screwdrivers with broken or worn handles.
5. Leave a knife unattended with the blade exposed.
6. Keep your free hand away from the line of the cut.
7. Always use a screwdriver tip that properly fits the slot of
the screw.
8. Use pliers on a screwdriver for extra leverage. Only use
wrench or screwdrivers specifically designed to accept
them.
9. Bend or apply side loads to blades by using them to open
cans or pay loose objects.
10.Use pliers as a hammer on the handle. Such abuse is likely
to result in cracks or breaks.
