2. gas products are handled in accordance with safety regulations set forth by the Occupational Safety and Health Administration, the Compressed Gas Association, and the Arizona Department of Transportation

Policy

All gas cylinders and compressed gas purchases must be made through Laboratory Stores.

All cylinders, except disposable and exchange cylinders, have a monthly rental fee due on the 15th of each month. Unless other arrangements have been made with Laboratory Stores, the cylinder rental fee will be charged to the agency/org provided at the point of sale. Some specialty gases have higher rental fees and require deposits. Laboratory Stores will notify the purchaser prior to the purchase if additional fees apply.

Procedure

1. Users may submit a completed ASU Stores Order form to mail code 5212 or fax to 480/965–0994

   or

2. Users may telephone their orders to 480/965–9079 providing their agency/org information, and Laboratory Stores will complete the ASU Stores Order form

   or

3. Users may purchase compressed gas cylinders in person at Laboratory Stores in PSG 110. Users are required to fill out an ASU Stores Order form using their agency/org information at the point of purchase.

To expedite these procedures, Laboratory Stores does not require authorized signatures for gas purchases. Departments that need to institute that authority may do so internally within their own organization. If a department wishes to use authorized signatures, it is the department’s responsibility to inform its users and their assistants of this change in procedure. In this case, a list of authorized signers and the corresponding agency/orgs must be provided to Laboratory Stores. D
