          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
    chisel
   Using tools with loose
    handles
