Abstract
An apparatus for storing used products such as fluorescent lights, thermometers, mercury vapor lamps and batteries which contain injurious substances, particularly mercury compound. Used products are accommodated in a housing and injurious substances suspended in air in the housing are drawn by a suction device. A filter and adsorbent unit are arranged in a passage of ventilating air so as to remove dust and mercury compound. The ventilating air is exhausted from an outlet portion after it has passed through the suction device.
