Tool Selection
  • Non-Powered
  • Electric
  • Air Powered
  • Powder Actuated
  • Gas Powered
  • Safety Note If you have to modify a tool to
    make it work, you probably dont have the right
    one!

3
Non-Powered Hand Tools
  • Impact tools such as chisels, wedges, or drift
    pins are unsafe if they have mushroomed heads.
  • Wrenches with sprung jaws should be taken out of
    service.
  • Wooden handled tools should be inspected
    periodically to make sure they are not
    splintered, cracked, or loose.

4
Electric Tools
  • Electric tools are difficult to guard completely
  • They are subject to more abuse than stationary
    tools
  • Cords must be inspected regularly
  • These tools should be unplugged/battery removed
    for all maintenance procedures.

5
Double Insulated Tools
  • NFPA 70 permits double insulation for portable
    tools
  • Third wire grounding is not necessary for
    double-insulated tools
  • Double insulation works by isolating the tools
    internal electric components from the outer
    housing

6
Circular Saw Safety Tips
  • Set the blades depth to no more than 1/8 to ¼
    greater than the thickness of the material
  • Avoid binding the blade and causing a kickback
  • Release the trigger if the saw binds or stalls
  • Never pull the saw out of a cut until the blade
    stops

7
Pneumatic Tools (Nail Guns)
  • Make sure the nose guard safety spring is
    functioning properly
  • Dont hook up the power source until it is time
    to nail
  • If the tool has to be carried while under power,
    stay away from the trigger and never carry
    against the body
  • Safety glasses are a must!
  • For Framers
  • Keep the off hand out of the way
  • Never nail beyond your reach
  • Keep the gun properly aligned with the work
  • Be aware of surroundings and fellow workers

8
Powder-Actuated Tools
  • Only employees who have been trained and
    certified in the operation of the particular tool
    shall be allowed to operate
  • Must be tested each day prior to use
  • If it doesnt pass inspection, it must be removed
    from service
  • All required PPE must be worn
  • Unfired caps should not be left in the gun or
    lying around
  • The loaded tool should never be left unattended

9
Gas Powered Tools
  • Types include leaf blowers, trimmers, mowers, and
    chainsaws.
  • Follow manufacturers recommendations for service
    intervals and safe use.
  • Take special care during refueling.
  • Give the equipment adequate cool down time.
  • Use only approved containers for fuel storage.
  • Never smoke during refueling.

10
Safe Work Practices Checklist
  • Always follow manufacturer recommendations
    regarding maintenance and safe use.
  • Inspect all tools prior to the start of work
  • Guards in place and working
  • All power cords in safe working condition
  • Timely replacement of blades, bits, etc.
  • Never bypass a safety feature.
  • Never modify a tool beyond its intended use.
  • Use all required personal protective equipment .

11
Housekeeping
  • Debris should be gathered and removed from site
    daily, weekly, as often as needed.
  • Plan for disposal of scrap, waste and surplus
    materials.
  • Keep the work area and all equipment tidy.
  • Designate areas for waste materials and provide
    containers.
  • Keep stairways, passageways, ladders, scaffold
    and gangways free of material, supplies and
    obstructions.

12
Housekeeping
  • Secure loose or light material that is stored on
    roofs or on open floors.
  • Keep materials at least 5 feet from openings,
    roof edges, excavations or trenches.
  • Remove or bend over nails protruding from lumber.
  • Keep hoses, power cords, welding leads, etc. from
    laying in high traffic areas.
  • Ensure structural openings are covered/protected
    adequately (e.g. sumps, shafts, floor openings,
    etc.)

13
Housekeeping
  • Do not permit rubbish to fall freely from any
    level of the project.
  • Use chutes or other approved devices to remove
    materials.
  • Do not throw tools or other materials.
  • Do not raise or lower any tool or equipment by
    its own cable or supply hose.
