CCDC CBC

A system and method to safely dispose of hazardous liquid waste includes a glove box for conducting a test with a hazardous liquid material therein, the glove box having a drainage line connected to a waste tank for directing the hazardous liquid waste from the glove box to the waste tank. A waste disposal line and an air vent line are connected between the waste tank and a waste container. Double-valved connectors are positioned in the waste disposal line and in the air vent line allowing the liquid waste and air to flow between the waste tank and a waste container when the double-valved connectors are coupled together. When the double-valved connectors are uncoupled, both the waste tank and the waste container are completely sealed to the surrounding environment.
