  • Any unsafe conditions identified in the jobsite inspection must be corrected prior to the use of an aerial lift in the jobsite area.
  • If the aerial lift is rated and used as an insulated aerial device, the electrical insulating components are tested for compliance with the rating of the aerial lift in accordance with latest ANSI standard A92.2. Such testing must comply with all of the following provisions:
    1. The test is performed not less than annually.
    2. Written, dated, and signed test reports are retained by the department responsible for the insulated aerial device.
  • The insulated portion of an aerial device must not be altered in any manner that might reduce its insulating value.
  • All danger, caution, and control markings and operational plates must be legible and not obscured.
  • A copy of the operator’s manual must be in a dry compartment on the aerial lift.

Operating Procedures

  • Only trained persons with a permit are allowed to operate an aerial lift.
  • Belting off to an adjacent pole, structure, or equipment while working from an aerial lift is not permitted.
  • Employees always stand firmly on the floor of the aerial lift, and may not sit or climb on the edge of aerial lift guardrails, or use planks, ladders or other devices for a work position.
  • A scissor lift with approved guardrails can be used without a personal fall arrest system.
  • The brakes must be set, and when outriggers are used, they must be positioned on pads or a solid surface.
  • The aerial lift is used in accordance with the manufacturer’s operating instructions and safety rules.
  • The designed rated capacity for a given angle of elevation must not be exceeded.
  • The manufacturer’s rated load capacity must not be exceeded. The load and its distribution on the platform must be in accordance with the manufacturer’s specifications. The aerial lift rated load capacity must not be exceeded when loads are transferred to the platform at elevated heights.
  • Only employees, their tools, and necessary materials are on or in the platform.
  • The guardrail system of the platform is not used to support materials, other lifts, or employees.
  • Employees maintain firm footing on the platform while working on the aerial lift. The use of railings, planks, ladders, or any other devices on the platform for achieving additional height is prohibited.
  • Fuel gas cylinders are not carried on bucket platforms that would allow the accumulation of gases.
  • Only aerial lifts equipped with manufacturer’s installed platform controls for horizontal movement may be moved while in the elevated position.
  • Before and during driving, an operator of a platform must look in the direction of travel, keep a clear view of the path of travel, and make sure that the path is firm and level. A driver must avoid:
    1. Pedestrians
    2. Vehicles
    3. Debris
    4. Drop-offs
    5. Holes
    6. Depressions
    7. Ramps
    8. Overhead obstructions
    9. Overhead electrical lines
    10. Other hazards to safe elevated travel.
  • Outriggers or stabilizers, when provided, are used in accordance with the manufacturer’s instructions. Brakes are set and outriggers and stabilizers are positioned on pads or a solid surface.
  • Aerial lifts are elevated only when on a firm and level surface or within the slope limits allowed by the manufacturer’s instructions.
  • A vehicle-mounted aerial lift must have its brakes set before elevating the platform.
  • A vehicle-mounted aerial lift must have wheel chocks installed before using the unit on an incline.
  • Climbers must not be worn while performing work from an aerial lift.
  • Platform gates must be closed while the platform is in an elevated position.
  • Altering, modifying, or disabling safety devices or interlocks is prohibited.
  • The permitted operator prevents ropes, cords, and hoses from becoming entangled in the aerial lift.
  • A platform operator ensures that the area surrounding the aerial lift is clear of personnel and equipment before lowering the platform.
  • The aerial lift must not be positioned against another object to steady the platform.
  • The aerial lift must not be operated from a position on a truck, trailer, railway car, floating vessel, scaffold, or similar equipment.
  • The boom and platform of the aerial lift are not used to move or jack the wheels off the ground unless the machine is designed for that purpose by the manufacturer.
  • If the platform or elevating assembly becomes caught, snagged, or otherwise prevented from normal motion by adjacent structures or other obstacles so that control reversal does not free the platform, all employees exit from the platform before attempts are made to free the platform.
  • Stunt driving and horseplay are prohibited.
  • Weather conditions such as wind and lightning are evaluated prior to raising the boom or platform. Manufacturer’s recommendations for use in windy conditions are followed.

Fall Protection

  • A permitted operator must use a safety harness that has a lanyard which is in compliance with the DHHS Fall Protection Plan and which is affixed to attachment points provided and approved by the manufacturer. A permitted operator may use a harness with a restraint device with the lanyard and the anchor arranged so that the employee is not exposed to any fall distance.
  • Any occupant of an aerial lift must use a harness.
  • A fall arrest system is only used where the aerial lift is designed to withstand the vertical and lateral loads caused by an arrested fall as specified by the manufacturer.
  • An employee must use a restraint device where the aerial lift cannot withstand the vertical and lateral loads imposed by an arrested fall as specified by the manufacturer.
  • A permitted operator is prohibited from tying off to an adjacent pole, structure, or equipment while working from an aerial lift.
  • A permitted operator must not exit an elevated aerial lift, except where elevated work areas are inaccessible or hazardous to reach. Employees may exit the platform with the knowledge and consent of the employer. When employees exit to unguarded work areas, fall protection must be provided and used.
  • A means of notifying emergency personnel for the prompt rescue of employees in the event of a fall must be present on the jobsite. A means for promptly rescuing employees who have fallen must be determined before the work begins. This could include self-rescue if such means are required.

Electrical Hazards

  • Workers in aerial lifts that are not electrically insulated must not come within 10 feet of energized overhead power lines.
  • Only specially trained high voltage personnel, with approved PPE and in approved insulated aerial lifts, are authorized to work within 10 feet of energized overhead power lines.

Traffic and Vehicular Hazards

  • Before moving a vehicle supporting an aerial ladder for highway travel, employees secure ladders in the lower position and must use the manually operated device at the base of the ladder, or other effective means to prevent elevation or rotation of the ladder.
  • Before moving a vehicle supporting an aerial lift for travel, employees inspect the boom to ensure it is properly cradled and the outriggers are in the stowed position.
  • When a vehicle-mounted elevating platform is elevated with employees in working position, the vehicle supporting an aerial device must not be moved.
  • Before and during travel, an operator must do all of the following:
    1. Inspect to see that booms, platforms, aerial ladders, or towers are properly cradled or secured.
    2. Ensure that outriggers are in a stored position.
    3. Limit travel speed according to the following factors:
    4. Condition of the surface
    5. Congestion.
    6. Slope
    7. Location of personnel
    8. Other hazards
  • Operators of an aerial lift over or adjacent to any public or private roadway must maintain adequate clearances of all portions of the aerial lift to prevent being struck by vehicular traffic.

Training

Employees must be trained in the hazards associated with the use of aerial lifts before their use. This training must include safety guidelines for avoiding hazards above, below, and beside the aerial lift. Documentation of this training must be maintained.

  • This training as a minimum must include:
    1. Fall protection and job hazards analysis
    2. Unstable surfaces
    3. Live power proximity
    4. Tipping hazards and outriggers
    5. Falling objects and barricading
    6. Load capacity of the aerial lift
    7. Crushing and pinch-points
    8. Wind exposure limits
    9. Sloping surfaces
    10. Ground surface pot holes
    11. Operation of the aerial lift “under the direction of a qualified person”
    12. Controls operation
    13. Emergency descent
    14. Operator’s manual Pre-operation inspection and record keeping
    15. Identification of malfunctions
    16. Purpose of placards and decals
    17. Operator warnings and instructions
    18. Function tests
    19. Evaluating the work site Hazards unique to the general type of aerial lift
  • It is expected that departments provide detailed training to staff based on the general type of aerial lift that their staff will operate (i.e. vehicle-mounted aerial lift, manually propelled elevating lift, boom-supported aerial lift, and self-propelled aerial lift).
  • It is not expected that multiple detailed training sessions need to be performed if an operator is to operate two different manufacturers’ models of a similar type of aerial lift. For example, an operator who is trained to operate self-propelled aerial lifts does not need to attend a detailed training course on a JLG model, if they attended detailed training on a Genie model. However, the trained operator is responsible for reviewing the model specific hazard information provided in the owner’s manual.
