As generators of hazardous chemical waste, UMD departments are responsible for ensuring that their employees follow University of Minnesota guidelines regarding the proper management and disposal of hazardous chemical waste within their laboratories, shops or service areas.
Evaluate Your Waste
Departments are required to evaluate their wastes, in compliance with Minnesota Rules, to ensure proper waste disposal. To determine if your unwanted chemicals (whether pure or in mixtures) are hazardous check if they are listed in the Chemical Waste Registry. If the chemicals are listed in the Registry and they do not have a nonhazardous designation ("xxNH" DDC number), then they must be managed as hazardous waste. If in doubt, Always manage the chemicals as hazardous waste. Remember sewering or trashing chemicals is not allowed very often and you must have proper permissions.
Collect the Waste in Appropriate Containers
Hazardous waste Collection bottles and lids must be compatible with the chemicals stored in them, both the bottle and screw cap must be chemically resistant to the waste chemical contained. Collection bottles must be kept capped, properly labeled, and stored in a safe location in the laboratory. Also, bottles containing liquids should be stored with secondary containment, such as a plastic tray or in proper safety cabinet. Drums if used should not be stored with an open bung or a funnel in them. All waste containers should be stored in appropriate locations, i.e. flammable liquid or acid storage cabinets.
