          Hazard Recognition

   Tools are common in “day-to-day” life
   Difficult to spot hazards due to familiarity
   Most tools manufactured with safety devices
   Users must inspect the tool daily
   Often misused

          Examples of Misuse

   Using a screwdriver as a
   Using tools with loose
   Wrenches with sprung jaws

         Other Safety Factors
   General housekeeping
   Use of personal protective equipment (PPE)
   Spark shield and protection around
   Don’t use tools near aisleways

        Types of Power Tools
   Electric
   Pneumatic (air)
   Liquid fuel
   Hydraulic
   Powder-actuated

General Power Tool Precautions
   Never carry a tool by the cord or hose
   Never yank the cord to unplug it
   Keep cords and hoses away from heat, oil,
    and sharp edges
   Disconnect tools when not in use

 Gears          Chains
 Shafts         Other moving parts
 Pulleys
 Sprockets
 Spindles
 Drums

     Guards Protect Against:
Guards will provide
protection for operators
from the following hazards:
 Point of operation
 In-running nip points
 Rotating parts
 Flying chips and sparks

       Power Tools Requiring
        Momentary Switches
 Drills
 Tappers
 Fastener drivers
 Horizontal, vertical, and angle grinders
 Disc and belt sanders
 Reciprocating saws
 Saber saws
Note: These tools can have a “lock-on” switch
      that turns off with a single finger motion

     Safety With Electric Tools
   Operate them within their design limitations
   Gloves and footwear are recommended
   When they’re not in use, store them in
    a dry location
   Do not use them in wet or damp locations
   Work areas should be well lighted

    Safety With Power Grinders
   Always use eye protection
   Turn off power when it’s not in use
   Never clamp a hand-held grinder in a vise

Hazards From Pneumatic Tools
   Being struck by attachments
   Being struck by fasteners, etc.
   Noise

           Safety With
       Powder-Actuated Tools
   Do not use in an explosive
    or flammable atmosphere
   Inspect the tool prior to use
   Never point the tool at anyone
   Load the tool only when it is going
    to be used
   Keep hands clear of the barrel end

            Safety With Jacks
   Set up a jack so that the base rests
    on a firm level surface
   Make sure the jack is centered
   Ensure that the jack head is against
    a level surface
   Be certain the lift force is applied evenly

         The Five Basic Rules
           for Power Tools
   Keep all tools regularly maintained
   Use the right tool for the job
   Examine each tool for damage
