6147 Appendix T3

Safe Operation of Aerial Work Platforms

 

 

1.0          Purpose

 

The purpose of this document is to define the requirements for safe operation of aerial work platforms used on behalf of Jefferson Lab.

 

2.0          Scope

 

This document is performed in coordination with ES&H Manual Chapter 6140 Material Handling Equipment Program and ES&H Manual Chapter 6147 Material Handling Equipment – Aerial Work Platforms.

 

3.0          Responsibilities

NOTE:           Management authority may be delegated at the discretion of the responsible manager.

 

3.1            Qualified Aerial Work Platform Operator

·       Use only the aerial work platforms on which you are currently authorized, in the manner which it was intended.

·       Minimum basic personal protective equipment (PPE) required:

o   Safety shoes

o   Safety glasses

(see ES&H Manual Chapter 6620 Personal Protective Equipment for more information).

·       Use appropriate fall protection in accordance with Jefferson Lab requirements.  (See ES&H Manual Chapter 6131 Fall Protection Systems).

 

4.0          Process Steps

 

Only a Qualified Aerial Work Platform Operator may perform the responsibilities below unless otherwise noted.  Refer to the manufacturer’s owner/operator’s manual for detailed instructions.

 

4.1            Preparation

 

Step 1       Pre-Work Inspect (Walk-Down) prior to commencement of work. 

·       Plan the route to and from the work site.

·       Walk the planned route:

o   Ensure adequate access of equipment and load,

o   Travel surfaces are free of debris, level, and firm (e.g., free of holes, bumps, unstable or slippery surfaces, etc.).

·       Inspect the work area:

o   Ensure clearance from:

§  Overhead obstructions: including ventilation or other duct work.

§  High voltage conductors: A minimum clearance of 10 feet is required between the aerial work platform (including its load) and electrical lines or apparatus carrying up to 50,000 volts.

 

NOTE:  Where power lines greater than 50,000 volts are located, increase the clearance one foot for increments of 30,000 volts.  For example:

  • 51,000 - 80,000 volts 11 foot clearance,
  • 81,000 - 111,000 volts12 foot clearance, etc.

 

·       Select the park location:

o   If working on a slope, ensure that the leveling capability is not exceed.

·       Coordinate with other operations in the area.

 

Step 2       Pre-Operational Inspection

Conduct a thorough visual inspection of the equipment prior to use.  (Refer to ES&H Manual Chapter 6140 Appendix T3 Inspection and Maintenance Procedure for Material Handling Equipment for pre-operational inspection process steps.)

 

Step 3        Moving the Aerial Work Platform

Follow owner/operator’s manual recommendations/requirements when moving an aerial work platform to and from the work area.

·       Follow the planned route.

·       Ensure that travel speed is appropriate to the conditions.

 

4.2            Aerial Work Platform Use

Step 1:          Don appropriate work PPE (including fall protection.)

 

NOTE:  Keep the platform lowered when equipment is parked or unattended.

 

Step 2:          Load equipment and worker onto the platform.  Do not exceed rated load limit.

 

Step 3:          Secure worker’s body harness to the proper attachment on the platform.  Ensure that the lanyard does not allow for a fall in excess of six feet.  Do not attach the harness to a pole, structure, or equipment outside of the platform.

 

Step 4:          Lift the platform.  The worker on the platform operates the aerial work platform controls.

 

Step 5:          Perform the work.

 

Step 6:          Lower the platform.

 

4.3            Return to Storage

Step 1:          Use Section 4.1. Step 3 Moving the Aerial Work Platform to return the aerial work platform to storage.

 

Step 2:          Park the aerial work platform in the designated area.

 

Step 3:          Secure aerial work platform in accordance with administrative procedure.

 

5.0          Failure

 

In the event an aerial work platform cannot be lowered with an operator on the raised platform, use the following steps.

 

Step 1       Call for assistance.  Remain on the platform until help arrives.

 

Step 2       Instruct “assistance” to lower the platform using auxiliary controls according to the owner/operator’s manual.

 

Step 3       Once off of the platform, lock and tag the aerial work platform out of service.

 

Step 4       Notify the Material Handling Safety Representative immediately and coordinate repair.
