Pollution prevention system

Abstract

There is disclosed a waste prevention system which avoids the discharge, inadvertent or otherwise, of laboratory waste, into a public sewage system and subsequently into the natural environment. The system employs, in combination, a laboratory sink having cooperatively connect thereto a carboy for collecting pollutants. The carboy is provided with elements to permit removal of samples of materials delivered thereto from the sink for testing of the same to determine the presence of pollutants. In the event no pollutants are present, the carboy may simply be opened and any wash or rinse water from the sink can be delivered into a public sewage system and then to the environment. In the event testing indicates the presence of pollutants, the carboy then can be filled to the required level, which is indicated by a sensing device connected electrically to signaling devices, such as a horn and/or light and which is also connected to the source of washing water and automatically will stop the flow of such washing water into the sink. The carboy can then be removed from the system and stored and/or disposed of, as desired.
