Most gas cylinders are rented and should be returned to the vendor when they are empty. It is strongly recommended that this method be used to dispose of gas cylinders.
If the vendor has been contacted and they will not collect the cylinders or if the vendor is unknown, then EHS will dispose of the cylinders. Fill out the Chemical Pick-Up Request form. This form will ask who you are, what room and building the cylinders are in, what cylinders you need to dispose of, and how many of each.
If you have any special instructions like where the cylinders are located within the room, or if you have special instructions on when the pick-up should occur, you can enter this information in the comments section.
The form will be submitted electronically to several members of EHS and someone will come and pick up the cylinders - usually within hours, but within up to three working days.
