At no time shall refrigerants be intentionally allowed to evaporate into the atmosphere. Certain laboratories and certain support activities of the university generate unwanted chemical material on a routine basis. Laboratories shall supply safety cans to collect separately spent halogenated and nonhalogenated solvents. It is the responsibility of each individual generator to ensure that all chemicals are contained in a closed, nonleaking container and the contents properly labeled. Proper labeling of a container includes listing the names of all chemicals in the container, as well as the relative percentage of each chemical.
Chemical formulas are unacceptable.
The materials shall either remain in their original containers or be accumulated in closed, nonleaking containers. It is the responsibility of EHS to determine the regulatory status of any material destined for disposal. EHS personnel will use criteria contained in OAC 3745-51. The program includes a chemical redistribution process in which the goal is to identify faculty and staff who can use chemicals no longer wanted by other faculty and staff. Additionally, EHS operates a distillation unit with the capabilities of distilling up to five gallons of certain used solvents per day.
