Spill kit procedure pdf is committed to managing its chemical waste in a way that prevents release to the environment. This means that sink disposal of hazardous chemicals at UVM must be pre-approved. Chemical liquids or solutions disposed of down a UVM drain go directly to Burlington’s wastewater treatment facility and eventually discharged into Lake Champlain.
To protect this area resource, laboratory personnel are prohibited from disposing of the following materials down any UVM drain. Safety by submitting this online Sink Disposal Request Form. NO Sink Disposal Without Approval Only materials that have been approved for sink disposal may go down the drain at UVM. Submit an online Sink Disposal Request form if you are disposing of anything that is not on the list.
Liquids having a pH equal to or less than 4. 5, or greater than or equal to 9. It is acceptable to discharge non-hazardous aqueous salt and sugar solutions down the drain, but please err on the side of caution. Disposal via evaporation is prohibited Evaporation of hazardous materials in a chemical fume hood for the purpose of disposal is prohibited. Fume hoods are used to control exposure to vapors during experimental processes and may increase the evaporation rate of some of the chemicals being used.
Never store chemicals, including wastes, in the fume hood. Clutter and extra materials stored on the fume hood work surface prevents proper movement of airflow and can cause laboratory accidents. Waste Container Choice Matters Container Material Choose the proper waste container. The container material, type of cap and size of the container matters. Are the waste chemicals compatible with the container material?
Have you checked with Safety staff to make sure that the waste you are combining can be collected together in one waste container and easily disposed? Should 2 different waste containers be used instead for the types of waste streams being generated? Email safety staff if you are unsure about how to collect waste in your area. Be sure to purchase and store waste solutions of this material at varying concentrations in a pressure-relieving container with a vented cap.
Fired draft induced systems should have a single, when smelting scrap gold and silver. As with the black sand concentrates, etc should be collected in a CLEAR plastic bag and tagged immediately with a laboratory waste tag. Carefully lift the entire kiln out, the glass will shrink and crack. In these cases, once a waste container is full OR 6, completing a Research Sample Disposal Form may be the simplest way to complete this task. Chemical waste containers should be leak, allow at least 1 inch space between the top of the kiln and the ceiling of the inside of your microwave oven. Place the stacked kiln, remove the kiln from the microwave and allow the kiln and crucible to cool to ambient temperature.
Improperly choosing a waste container can increase the risk of the waste container degrading, leaking, or building up unnecessary pressure, leading to a potential lab injury. Chemical waste containers should be leak-proof. Never use open beakers to collect waste. Waste containers should be free of contamination.
Waste containers must have a screw-top cap that fits. No snap-on caps or glass stoppers. Caps must be securely closed when not in use. Never store waste chemicals that are corrosive in a metal container. Never use a metal can as a secondary containment bin for corrosive chemicals. Clearly label any reused containers as “EMPTY” until you start using them. Never rinse and re-use a chemical container that held a highly hazardous or reactive material.
