Appendix T2 Moving Gas[1]
Cylinders from Building Storage
to Work Area |
||
|
|
|||
|
Jefferson Lab has determined that working with gas(es) carries an unmitigated Risk Code >2. In accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process discuss unmitigated Risk Codes = 2 with your Supervisor. If the unmitigated Risk Code is >2 an Operational Safety Procedure (OSP) is required unless standard protecting measures or engineering controls are the only mitigation necessary to reduce the Risk Code to <2. |

Purpose
Jefferson Lab recognizes the inherent risks of moving gas cylinders, tanks, and dewars (cylinders) from a building storage area to a work location within that building. This appendix provides Jefferson Lab’s minimum requirements for performing this operation. Only Qualified Gas Workers are authorized to perform these process steps.
2.0
Scope
It is recognized that listing the requirements for every gas used at Jefferson Lab would be prohibitive, it is therefore required that Qualified Gas Workers read and follow the recommendation provided on a gas’ material data safety sheets (MSDS). This document defines actions required by Jefferson Lab in coordination with or addition to those listed on the MSDS.
The process steps for these procedures are performed in coordination with ES&H Manual Chapter 6150 Compressed, Liquefied, and Solidified Gas Program.

Responsibilities
NOTE: Management authority may be delegated at the
discretion of the responsible manager.
3.1 Qualified Gas Worker
· Contact Industrial Hygiene for a hazard evaluation if a new gas, or significantly changed procedure is to be used.
· Do not use any cylinder that is damaged, leaking, or has illegible or otherwise unintelligible labels. (Remove to an outdoor storage area and notify the Fire Protection Engineer.)
· Transport compressed and liquefied gas cylinders in accordance with this procedure.
3.2 Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor
· Ensure storage area is secure and adequate for the gas hazard category(s).
· Ensure only authorized Qualified Gas Workers are assigned to moving gas cylinders.
Unless otherwise stated the process steps in
this procedure are completed by a Qualified Gas Worker.
4.1 Pre-Movement Inspection Activities
Step 1 Verify that the MSDS is available and appropriate.
Step 2 Don appropriate personal protective equipment (PPE) as required.
Step 3 Inspect the cylinder for damage and accuracy of labeling.
Follow the steps below when moving cylinders from storage areas to the work area and back. Do not use stairways. See Section 4.4 Transportation of Cylinders on Elevators if route includes moving cylinder on an elevator.
Step 1 Walk the route. Make sure path is clear. Do not use stairways.
Step 2 Obtain a gas cylinder hand truck (with securing strap or chain) appropriate for the cylinder to be moved.

NOTE: Use proper equipment for moving
cylinders. Rolling, dragging, or
lifting cylinders is prohibited. |

Step 3 Place the cylinder(s) on the gas cylinder hand truck and secure with the strap or chain.
Step 4 Move the cylinder to the work or storage area.
Step 1 Upon arrival at the work/storage location. Remove the cylinder from the gas cylinder hand truck.
Step 2 Secure the cylinder to the wall or storage location with strap, chain, or guard, to prevent falling or tipping.
Step 3 Return gas cylinder hand truck to appropriate location in accordance with department procedures.
4.4 Moving Cylinders on Elevators
4.4.1 Additional Materials and Required Assistance
·
If
required, obtain the elevator “independent service” key from the Fire
Protection Engineer.
·
Print a “Caution
Sign” (click button below for printable version)
· Bring Tape.
·
Ask a
second person to assist. Review “Step 4 Retrieval” duties with the person to ensure they
are willing and able to perform the activities.
Step 1 Transport the Cylinder to the elevator per Section 4.2 Transporting Cylinder
Step 2 Arrive at Elevator
· Attach the caution sign to the handle of the hand truck with the tape.
Step 3 Position Hand Truck in Elevator
· Send the assistant to meet the elevator at the destination floor.
· Press the elevator call button.
· Upon arrival use the elevator “independent service” key to STOP the elevator (maintain positive control).
· Wheel the hand truck onto the elevator.
· Position the caution sign so it is immediately noticeable to those who may want to enter (i.e., between the hand truck and elevator doors).
· Release the elevator by positioning the elevator “independent service” key to the “OFF” position.
· Leave the key in the lock!
· Press the destination floor button.
· Exit the elevator.
|
NOTE: Never ride in an elevator
with a compressed, liquefied, or solidified gas cylinder. |
Step 4 Retrieval – (This step is completed by the second person.)
· Wait for the elevator at the destination floor.
· Upon arrival enter the elevator.
· Position the elevator “independent service” key to STOP the elevator (maintain positive control).
· Remove the hand truck and the cylinder from the elevator.
· Position the hand truck and cylinder out of the line of traffic.
· Re-enter elevator and position the elevator “independent service” key to the “OFF” position.
· Remove the key.
· Exit the elevator.
· Wait for the Qualified Gas Worker for further instructions.
|
Do not leave the hand truck or gas cylinder
unattended. |
Step 5
Clean-up
· Continue transporting the cylinder to the work or storage area per Section 4.2 Transporting Cylinder.
· Return the elevator “independent service” key to the Fire Protection Engineer.
