Title: Hand and Power Tool Safety


1
Hand and Power Tool Safety
2
DIFFERENCE BETWEEN Hand Tools AND 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.

4
General 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

5
General 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.

6
Hand 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.

7
Hand 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.

8
SAFETY RULES For SPECIFIC Hand Tools
  • HAMMERS
  • 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

9
SAFETY RULES For Hand Tools contd
  • CHISELS
  • 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.

10
SAFETY 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

11
SAFETY 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.

12
SAFETY 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.

13
SAFETY 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.

14
SAFETY RULES For Hand Tools contd
  • SAWS
  • 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

15
Todays 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.

16
Hazards 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.

17
General 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.

18
General 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.

19
General 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.

20
General 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."

21
Power 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.

22
Portable 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.

23
Portable 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.

24
Disc / 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

25
Band 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.

26
Band 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.

27
Pneumatic 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.

28
Pneumatic 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.
