Appendix T1 Authorized
Use of Tunnel Vehicles |
||
|
|
|||
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 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.
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).
NOTE: Management authority may be delegated to a task qualified Jefferson Lab employee 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.
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.
·
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.
Step 1:
Walk
the Route
·
Ensure 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.
In accordance with the work plan.
4.4.1
Built-In Charging Systems (typically
for 3-wheel tow carts)
·
Plug the power cord
that is 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. Refer to ES&H
Manual Chapter 6200 Appendix T3 General Electrical Safety Guidelines if
there are any questions about the condition of the power cord. |
