1. Dry ice is on hand primarily for use by the Department of Chemistry and Biochemistry. Keys for the dry-ice freezer (located in building 65 room 230) may not be used to open the freezer for non-departmental users. Please do not leave you group keys in room 230. A second freezer for dry ice is only for use by organic research. It is located on the second floor of chemistry building 55. 2. Extra dry ice may be sold to other departments only if there is enough dry ice for the department. About 10% of the ice purchased by the department is sold to other departments. Normally, requests for dry ice are made by phone (Keith 6-4627). He will decide if there is enough for the departmental use and for sale. If other departments need more than a couple of pounds they must advise the department, in advance, of the amount and date before they can obtain dry ice. Dry ice is normally only ordered once a week. The department maintains at least 75 pounds exclusively for its use over the weekend and will not make sales on Friday, unless there is a delivery of fresh dry ice on Friday. Orders of dry ice normally take a couple of days to be processed and received. Extreme emergency may allow some modification of the normal rules. About half of the dry ice is lost due to fine chips formed when removing a block and sublimation. If the department can not supply enough dry ice it is also for sale at local stores.
3. Normally, payment for dry ice is made using a valid university account number. Valid index numbers have the following format: _ _ _ _ _ _. Payment may also be made in cash for users without account numbers, and will be placed in departmental petty cash. Normally change can not be made therefore the cost will be rounded up to the nearest dollar.
4. Anyone wishing to purchase departmental-dry ice must supply a container to carry the dry ice, ask for the dry ice deep freeze (located in room 230) to be unlocked, chip the requisite amount of dry ice, weigh the dry ice, record the amount of dry ice being purchased in the log book as well as in the departmental voucher book. Once the voucher is completed and approved by the salesperson the pink copy is removed and given to the customer. No other copies are removed from the voucher book. The voucher book is used by the department for reimbursement and must be completed by the buyer according the following protocol:
5. Voucher books are submitted for payment, quarterly.
