8
Interlock Devices
  • Driving interlocks prevent moving until lift is
    lowered
  • Outrigger interlocks limit lift height until
    stabilizers are extended

    base is on a slope

9
Maintenance
  • Equipment must be inspected, maintained, and
    repaired according to manufacturers instructions

10
Lift Safety Features
  • Skid-resistant stepping, standing, and working
    surfaces
  • Access way with slip-resistant surfaces
  • Sides or top guardrail must be high enough to
    prevent worker from falling out
  • The lift must be kept clear of debris
  • Attachment point provided for a full-body harness

  • Attachment point provided for a full-body harness

11
Controls
  • Controls both in lift and on vehicle
  • Controls within easy reach of operator
  • Controls plainly marked as to function
  • Lower controls can override lift controls

    operated with permission from worker in lift

12
Power Lines
  • Insulated portion not altered to reduce
    insulating value
  • Insulating blankets, covers, line hose, gloves,
    sleeves
  • Look for holes, tears, embedded objects,
    swelling, softening, hardening, stickiness,
    inelasticity
  • Damage caused by light, temperature, corrosive
    materials and solvents, humidity
  • Insulated portion not altered to reduce
    insulating value

    sleeves
  • Look for holes, tears, embedded objects,
    swelling, softening, hardening, stickiness,
    inelasticity
  • Damage caused by light, temperature, corrosive
    materials and solvents, humidity

13
OSHA RequirementsTrue or False?
The primary hazard of aerial lifts is eye
injuries. The rated load capacity must be
displayed on the equipment. Interlock devices are
used to protect operators from electrocution. Lowe
r controls must be able to override upper
controls.

26
Safe Work PracticesMake the Safe Choice
a. Optional
Fall protection for lift operators is Aerial
lifts must be inspected Before moving a vehicle,
the boom should be Workers on the ground near
aerial lifts must wear
b. Required
a. Weekly
b. Daily
a. Extended
b. Cradled
a. Hard hats
b. Gloves
27
Safe Work Practices
  • Do you understand
  • Fall protection requirements?
  • Inspection procedures?
  • Vehicle setup rules?
  • Safe work practices for employees in the lift
    and on the ground?
  • Safe driving rules for vehicles equipped with
    aerial lifts?
  • Do you understand
  • Fall protection requirements?
  • Inspection procedures?
  • Vehicle setup rules?
  • Safe work practices for employees in the lift
    and on the ground?

Key Points to Remember
Aerial lifts are useful but can also be
hazardous. Only operate an aerial lift if trained
and authorized. Inspect equipment and the work
area before each use. Understand and follow safe
work practices, including wearing fall
protection. Be especially careful around power
lines.
