It is common practice to store toxic volatile chemicals in a laboratory fume hood. While this provides safe storage, the fume hood must be operated continuously, resulting in a constant loss of conditioned air in the building. Typically, bottles containing highly toxic chemicals are small in number.

The top of the clean gas storage cabinet is equipped with a fan and a filtering device. The operation of the fan creates a negative pressure in the cabinet, and the air enters from the air inlet.
