   Recent OSHA estimates indicate that each
    year 120 deaths and 60,000 injuries occur
    as the result of unexpected activation of
    machinery, and nearly 75% of these
    accidents occur on jobs of 15 minutes or
    less.

         Fatal Incident
   A 28 year old dump truck driver was
    crushed when pinned between the
    dump body and frame. The victim
    elevated the empty body and tried to
    lower it, but it had stuck in the
    elevated position. He left the cab
    leaned over the truck frame to look at
    the control valve. The dump body
    suddenly lowered pining him. He was
    found the next day by the company
    owner who was his father.
