Aerial Lifts


This program has been established to, ensure the safe operation of aerial and scissor lifts; ensure that work units understand and comply with safety standards related to aerial / scissor lifts; and assign responsibilities to personnel which are necessary for successful implementation.


This program applies to all employees using aerial and scissor lift equipment.


Aerial Lifts - Any powered, mobile, vehicle-mounted device that may elevate, telescopically extend, articulate and may (or may not) rotate around a substantial axis in order to raise and support personnel to elevated job sites. Aerial lifts include extendible boom platforms; vehicle-mounted aerial ladders; articulating, rotating boom platforms; vertical self-elevating towers; cherry pickers; bucket trucks and any other equipment built in accordance with either ANSI-A92.2 (1990), Vehicle-Mounted Elevating and Rotating Aerial Devices, or ANSI-A92.5 (1992), Boom Supported Elevating Work Platforms.

Scissor Lifts - Any powered, mobile device that has a personnel work platform which is mechanically raised vertically above the carriage by means of controls on the work platform. This equipment is designed and fabricated according to either ANSI-A92.6 (1990), Self-Propelled Elevating Work Platforms, or ANSI-A92.3 (1990), Manually Propelled Elevating Aerial Platforms.

Anchorage - A secure point of attachment to be used with personal fall protection equipment.

Certified Operator - Certification of aerial/scissor lift operators at PSU is a three-step process consisting of classroom instruction, hands-on training and hands-on evaluation.  Once the employee has successfully completed all three steps they are considered to be a certified operator.

Competent Trainer - An employee who has successfully completed a Train–the–Trainer or equivalent type of training program and is familiar with the type of aerial/scissor lift in their work area.  A contractor or equipment vendor who has experience training aerial/scissor lift safety and operation and is familiar with the equipment is also permitted to be a Competent Trainer.

Competent Evaluator (Hands-on) - An employee in the department/work unit who is experienced and competent with the aerial/scissor lift.  An employee must be familiar with the equipment and its safe operation.  In order to be considered competent in regards to conducting the evaluation portion of the aerial/scissor lift training, an employee must have successfully completed the classroom portion of aerial/scissor lift training.  This employee could be but is not limited to a certified operator, supervisor/manager or safety officer. 

Familiarization - Providing information regarding the control functions and safety devices for the aerial /scissor lift to an operator of the equipment.

Insulated Platform - A platform designed and tested to meet the specific electrical insulation ratings consistent with the manufacturer’s identification plate.

Outriggers - Devices that increase the stability of the aerial lift platform and that are capable of lifting and leveling the aerial / scissor lift platform.

Rated Work Load - The designated capacity of the aerial platform as specified by the manufacturer.

Stabilizers - Devices that increase the stability of the aerial lift platform but are not capable of lifting or leveling the aerial / scissor lift platform.

General Requirements

  • Operators shall review and follow the manufacturer’s operating manual.  A copy of the manual must be located on the equipment.
  • Only certified operators shall operate an aerial / scissor lift.
  • Operators shall follow safe work practices when operating an aerial/scissor lift; a list of common safe work practices are summarized in Appendix F.

Pre-Use Inspections

  • Every aerial/scissor lift must undergo a pre-use inspection prior to use on each shift.
  • Aerial/scissor lifts not used during a shift do not have to undergo an inspection during that shift.
  • Pre-use inspections must be documented using an appropriate checklist for the aerial/scissor lift similar to the one in Appendix A.  Refer to the manufacturer's inspection requirements for complete inspection details.
  • Completed checklists will be kept on file for a period not less than a year.
  • The pre-use inspection will identify conditions that could affect the safe use of the aerial/scissor lifts.  If any unsafe conditions exist, the aerial/scissor lift shall be removed from service.  In order to remove an aerial/scissor lift from service, the operator shall remove the keys and place an “Out of Service” tag near the operator control panel.
  • Operators must immediately report any unsafe aerial/scissor lift conditions to their supervisor.  When an aerial/scissor lift has been removed from service, the operator must give the keys to the supervisor for safekeeping.  The supervisor is then responsible for ensuring the necessary arrangements are made for repair.
  • Only authorized personnel shall perform aerial/scissor lift repairs and adjustments.  All replacement parts shall be the same design as the original or an equivalent design as designated by the manufacturer.

Training must be completed prior to any use of the aerial/scissor lift. Certification of aerial/scissor lift operators at PSU is a three-step process consisting of classroom instruction, hands-on training and hands-on evaluation. 

Classroom instruction, hands-on training and hands-on evaluation can be conducted by either a competent trainer in the work unit, equipment manufacturer, safety consultant and/or a vendor who specializes in aerial/scissor lift training.

  • Hands-on training and hands-on evaluation portions of the training can also be conducted by an employee in the department/work unit who is experienced and competent with the aerial/scissor lift.  This person could be a certified operator, supervisor/manager or safety officer.
  • EHS must approve trainers.

Training must be specific to the type of aerial/scissor lift being used.

Training must cover the following:

  • The purpose and use of the equipment manuals.
  • That operating manuals are an integral part of the lift and must be properly stored on the vehicle.
  • A pre-start inspection.
  • Responsibilities associated with problems or malfunctions affecting the operation of the lift.

Employees shall not be allowed to operate rented equipment unless they have been previously certified on similar equipment.  Operators are also required to review the owner’s manual and shall be given ample time to become familiar with the equipment and its controls before operation is permitted. The vendor is required to review equipment with the user when the user is not familiar with the type of aerial/scissor lift.

Trainees must successfully complete hands-on training and a hands-on evaluation before being allowed to operate an aerial/scissor lift independently.  Trainees will be given adequate supervision and time to learn basic operating skills.

Initial operator hands-on evaluations must be completed using the checklist found in Appendix D or equivalent.

Documented re-evaluation of each aerial/scissor lift operator will be completed at least once every three years.

  • Re-evaluations can be conducted by an employee in the department/work unit who is experienced and competent with the aerial/scissor lift.  This person could be a certified operator, Supervisor or EHS Officer.

Refresher training in relevant topics will be provided to an aerial/scissor lift operator when any of the following occur:

  • The operator has been observed to be using the aerial/scissor lift in an unsafe manner.
  • The operator has been involved in an accident or a near-miss incident.
  • The operator has received an evaluation that reveals the operator is not using the aerial/scissor lift safely.
  • The operator is assigned to operate a different type of equipment.
  • A condition in the workplace changes in a manner that could affect safe operation of the equipment.


Contractors are required to follow all applicable OSHA regulations and manufacturer’s instructions. Contractors are not permitted to use any aerial/scissor lifts owned by the University.  


  • The manufacturer’s instructions regarding maintenance must be followed.  (Such instructions are typically included in the owner’s manual for the aerial/scissor lifts).
  • An annual inspection is required and must be conducted by an authorized person qualified as a mechanic on the type of aerial / scissor lift or one having similar design characteristics.
  • Any aerial/scissor lift with an identified safety issue will be immediately removed from service.
  • Maintenance performed by certified aerial/scissor lift operators will be limited to replacing/disconnecting/connecting batteries, changing fuel cylinders, adding water to batteries, replacing light bulbs and replacing stickers and decals.
