Title: Hand and Power Tool Safety
1Hand and Power Tool Safety
2DIFFERENCE BETWEEN Hand ToolsAND Power Tools
- Hand tools
- Have no power source, other than the physical
force applied by the user. Hand- tools include
anything from axes to hammers, and screwdrivers
to wrenches. - Power Tools
- Require a non-human power source to function
properly--e.g. External (electricity,
compressed air, etc.) or Internal (battery pack,
internal combustion engine, etc.).
3- Both kinds of tools require specific safety
precautions or rules to be followed yet some
rules will apply to both. - There are seven basic rules that apply to all
tools used either hand or power.
4General Safety Precautions
- Keep all tools in good working order
- Use the tool only for what it is designed to do
- Examine the tool for damage before each use
- Always follow the manufacturers instructions
when operating any tool - Wear proper apparel. Do not wear loose clothing,
dangling objects or jewelry. Long hair must be
restrained. Gloves should not be worn when
operating certain power tools. Check with Mr.
Lewis
5General Safety Precautions
- Appropriate personal protective equipment should
be worn due to hazards that may be encountered
while using portable power tools and hand tools. - Floors should be kept as clean and dry as
possible to prevent accidental slips with or
around dangerous hand tools.
6Hand Tools
- Hand tools are non-powered. They include anything
from axes to wrenches. The greatest hazards posed
by hand tools result from misuse and improper
maintenance.
7Hand Tool Misuse
- The greatest hazards posed by hand tools result
from misuse and improper maintenance. - Some examples
- Using a screwdriver as a chisel may cause the tip
of the screwdriver to break and fly, hitting the
user or other employees. - If a wooden handle on a tool such as a hammer or
an axe is loose, splintered, or cracked, the head
of the tool may fly off and strike the user or
another worker. - Wrenches must not be used if the jaws are
sprung, cracked or twisted - Impact tools such as chisels, wedges, or drift
pins are unsafe if they have mushroomed heads.
The heads might shatter on impact, sending sharp
fragments flying.
8SAFETY RULES For SPECIFIC Hand Tools
- Use a claw hammer for pulling nails
- Do not strike a hardened steel surface with a
claw hammer - Do not strike one hammer against another hammer
- Do not use a hammer as a wedge or pry-bar
9SAFETY RULES For Hand Tools contd
- The greatest hazards posed by hand tools result
from misuse and improper maintenance. - Use only chisels that are sharp
- Do not use chisels with a mushroom head
- Use only hammers that are designed for use with
chisels.
10SAFETY RULES For Hand Tools contd
SCREWDRIVERS
- Always ensure the screwdriver fits the head of
the screw - Do not hold the work piece against your body
while using the screwdriver - Do not use a screwdriver as a punch, chisel, pry
bar or nail puller - Do not use a screwdriver to make a starting hole
for screws
11SAFETY RULES For Hand Tools contd
SNIPS / WIRE STRIPPERS
- Do Wear safety glasses or goggles when using
snips or wire strippers - Do not use as a hammer, screwdriver, wrench or
pry bar - Use the correct type of snips for the job
- Do not use excessive force when working with the
snips or wire strippers.
12SAFETY RULES For Hand Tools contd
Soldering
- Always check the cord for wires that are showing
hrough the protective rubber. Fix with
electrical tape and show the teacher. - Always put the soldering iron in its station
before and after use. - Always soak the sponge, and rinse it out before
use of the soldering iron. - Always put up loose hair, never were loose
clothing, always wear safety glasses.
13SAFETY RULES For Hand Tools contd
Soldering
- Always wipe off excess solder.
- Always make a precise soldering job.
- Never take your eyes of the job that you are
doing. - Never touch the end of the soldering iron when it
is plugged in.
14SAFETY RULES For Hand Tools contd
- Do not carry the saw by the blade
- Do not use any saw that has a dull saw blade
- Keep control of the saw by releasing downward
pressure at the end of each stroke
15Todays Power Tools
- Offer more power, adaptability and dependability
than ever before. - With enhanced tool performance comes the
responsibility to address power-tool safety
issues. - Students are responsible for specifying and using
power tools and have a responsibility to check
out a tool's safety features, then ensure that
the teachers safety precautions and common sense
are followed at all times.
16Hazards of Power Tools
- All hazards involved in the use of power tools
can be prevented by following five basic safety
rules - Keep all tools in good condition with regular
maintenance. - Use the right tool for the job.
- Examine each tool for damage before use.
- Operate according to the manufacturer's
instructions. - Provide and use the proper protective equipment.
17General Safety Guidelines for Power Tools
- Power tools can be hazardous when improperly
used. - There are several types of power tools, based on
the power source they use - electric, pneumatic, liquid fuel, hydraulic, and
powder-actuated. - Students should be trained in the use of all
tools - not just power tools. They should
understand the potential hazards as well as the
safety precautions to prevent those hazards from
occurring.
18General Safety Guidelines for Power Tools
- The following general precautions should be
observed by power tool users - Never carry a tool by the cord or hose.
- Never yank the cord or the hose to disconnect it
from the receptacle. - 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.
19General Safety Guidelines for Power Tools
- All observers should be kept at a safe distance
away from the work area. - Secure work with clamps or a vise, freeing both
hands to operate the tool. - Avoid accidental starting. Students should not
hold a finger on the switch button while carrying
a plugged-in tool.
20General Safety Guidelines for Power Tools
- Be sure to keep good footing and maintain good
balance. - The proper apparel should be worn. Loose
clothing, ties, or jewelry can become caught in
moving parts. - All portable electric tools that are damaged
shall be removed from use and tagged "Do Not Use."
21Power Tool Accessories and Attachments
- There's a variety of accessories available for
use on or with power tools. - Caution must be exercised when selecting and
using any accessory with any power tool. - Choosing the wrong accessory or using an
accessory incorrectly can result in serious
injury. - Unplug tools before installing, adjusting and
changing any accessory or attachment of any kind.
22Portable Drill / Drill Press Safety Precautions
- Check carefully for loose power cord connections
and frays or damage to the cord. Replace damaged
tool and extension cords immediately. - Be sure the chuck is tightly secured to the
spindle. This is especially important on
reversible type drills. - Tighten the bit securely as prescribed by the
teacher. The chuck key must be removed from the
chuck before starting the drill. A flying key can
be an injury-inflicting missile.
23Portable Drill Safety Precautions
- Check auxiliary handles, if part of the tool. Be
sure they are securely installed. Always use the
auxiliary drill handle when provided. It gives
you more control of the drill, especially if
stalled conditions occur. Grasp the drill firmly
by insulated surfaces. - Always hold or brace the tool securely. Brace
against stationary objects for maximum control.
If drilling in a clockwise -- forward --
direction, brace the drill to prevent a
counterclockwise reaction. - Don't force a drill. Apply enough pressure to
keep the drill bit cutting smoothly. If the drill
slows down, relieve the pressure. Forcing the
drill can cause the motor to overheat, damage the
bit and reduce operator control.
24Disc / Belt Sander Safety Rules
- Wear safety glasses or a face shield when using
the sanders. - Only 1 person may use each sander at a time.
- Hold the material firmly in your hands and on the
table when sanding. - Keep fingers away from the abrasive surfaces on
the sander. - Sand on the downward motion side of the disc
sander. - Clean up the sander and the floor around the
sander when completed
25Band Saw Safety Rules
- Wear safety glasses or a face shield when using
the band saw. - Keep fingers away from the blade and out of the
blades path when cutting. - Do not allow hands across the saw line when
operating the band saw. - When the cut is almost complete, ease up on the
forward pressure.
26Band Saw Safety Rules
- If the blade breaks, keep clear of the blade,
shut off the power, and notify the teacher. - The band saw is only for cutting straight cuts.
After cutting, the material can be rounded on the
disc\belt sander. - When backing out of a cut keep the wood perfectly
straight and pull it out slow and carefully. - Clean up the band saw and the floor around the
band saw when completed.
27Pneumatic Tools
- Pneumatic tools are powered by compressed air and
include chippers, drills, hammers, and sanders. - There are several dangers encountered in the use
of pneumatic tools. - The main one is the danger of getting hit by one
of the tool's attachments or by some kind of
fastener the student is using with the tool. - Eye protection is required and face protection is
recommended for employees working with pneumatic
tools.
28Pneumatic Powered Tools
- Airhose. Hose and hose connections used for
conducting compressed air to utilization
equipment shall be designed for the pressure and
service to which they are subjected.
