ES&H Manual

 

DOCUMENT ID:

6146 Appendix T1

Authorized Use of Tunnel Vehicles

 

 

1.0          Purpose

 

Only Material Handling Equipment that does not produce noxious emissions (battery operated or manually powered) is authorized for use within the accelerator enclosure (tunnel).  This document defines the minimum requirements needed to authorize the use of this type of equipment in the tunnel, the additional activities required when it is used, and how to store/recharge it safely.  

 

This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.

 

2.0          Scope

 

Actions not presented in this appendix are to be reviewed and approved by the worker’s supervisor prior to implementation.

 

The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6140 Material Handling Equipment Program and ES&H Manual Chapter 6146 Material Handling Equipment – Non-Emission or Manually Propelled Equipment (Tunnel Vehicles).

 

3.0          Responsibilities

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

 

3.1            Qualified Material Handling Equipment Operator

·       Only use authorized material handling equipment within designated areas.

·       Walk the designated route before starting operations.

 

3.2            Supervisors/Subcontracting Officer’s Technical Representative (SOTR)

·       Only authorize the use of the appropriate material handling equipment in the tunnel area using an approved work plan.

 

4.0          Process Steps

 

4.1            General Requirements

 

Step 1:          Authorization

Only authorized material handling equipment is allowed to be used in the tunnel and only when all the following conditions apply:

·       The beam is not in operation;

·       An authorized work plan has designated the equipment to perform a specific task; and

·       A pre-determined period of time is specified (e.g., scheduled accelerator downs).

 

Step 2:          General

Because of the limited mobility within the tunnel courtesy and common sense are required.  This includes:

·       Pedestrians have the right of way.

·       Individuals working at elevation (on a ladder or aerial work platform) must dismount.  (During the “Walk-through” the Qualified Material Handling Operator is to coordinate with the elevated worker.)

 

4.2            Work Planning Activities

 

Step 1:          Walk the Route

·       Ensure that there are no obstacles to impede passage of equipment.

·       Coordinate with other workers to:

o   Dismount from ladders or aerial work platforms,

o   Move obstacles as required.

·       Any questions or conflicts are directed to the area work coordinator.

·       If vacuum pumps need to be moved additional care is needed to avoid tripping off the pumps.  Contact the Vacuum Group and have one of their technicians move the equipment if necessary

 

Step 2:          Cordon off the Area (if required)

·       When a task of long duration is scheduled (e.g., magnet installation or removal), cordon off the area to prevent pedestrian traffic for the duration of the work.

 

4.3            Perform the Work

In accordance with the work plan.

 

4.4            Storage/Battery Charging

 

4.4.1       Built-In Charging Systems (Typically for 3-wheel tow carts)

·       Plug the power cord (permanently attached to the equipment) directly into a convenient wall receptacle (typically the North or South Access Building Crane Pits).  The equipment will then automatically start charging its batteries.

 

4.4.2       Free Standing Charging Stations (Typically electric-powered forklifts)

·       Located under the “hatch” in either the North or South Access Building[1]. 

·       Charger must be in the “off” position when connecting or disconnecting equipment.  (This prevents open flames, sparks, or electric arcs in the area.)

 

NOTE: As with any other piece of equipment, inspect the power cord per Jefferson established practices.  See ES&H Manual Chapter 6200 Appendix T4 General Electrical Safety Guidelines if there are any questions about the condition of the power cord.
