For empty small disposable helium tanks (such as those used for balloons) turn the valve all the way to the left (to allow remaining gas to escape) and place in the garbage. For full or partially full tanks, use up or vent first by turning the valve all the way to the left. Then place in garbage.
For large helium tanks refer to the information on commercial gas cylinders.
See the following for locations, times of operation, and what is accepted.
NOTE: See the Business Waste pages for more information about commercial waste exchange and disposal.
