As a general note, email email@example.com with any question comments or concerns, we will gladly reply
Every container should first be labeled with the words “Hazardous Waste” at the top, then it should be followed by a list of the chemicals in the container, using full chemical name not formulas or abbreviations. If there is any hazard of other important information it should also be labeled (i.e. Toxic, Flammable, Corrosive, Water/Air Reactive, Oxidizer, Explosive, etc.).
Write down the ones with the largest volume and the ones that cause the most hazards.
Label the containers with the words “Hazardous Waste” at the top, then it should be followed by “Unknowns”. If you believe you know the contents write that below unknowns. Please contact us for proper disposal methods.
The Hazardous Waste may be placed in the same receptacle it was originally stored in and then properly labeled to be disposed of. If the receptacle is still being used for the original substance or would not like to be disposed of email firstname.lastname@example.org with your building, room, the chemical(s) being used, whether it is a solid or liquid, quantity being produced, and frequency of production. The EHS will then supply you with the proper container to use. Please do not use containers that have had other uses, such as old food containers.
The waste handler will normally take the container once it is 85% full or more, replacing the container with one of similar size. Waste handlers attempt to visit every room every week if time permits, but by emailing email@example.com with your building, room number, container size(s), and chemical name(s) it will be bumped in the priority list.
Email firstname.lastname@example.org with the your building, room, container size(s), and chemical name(s) indicating that you will no longer be producing this waste.
All Hazardous Waste must be segregated to prevent incompatible mixtures. Segregation can be by hazard class. Hazard class examples include: Flammable, Oxidizer, Pyrophoric, Reactive, Reducer, Acid, Base, and Toxic. For more information on specific chemical incompatibility, consult a material safety data sheet (MSDS) or feel free to email email@example.com.
ONLY glass. It is okay for contaminated glass to be placed in the bucket; however if it is contaminated with a chemical exemplifying the characteristics of Toxic, Flammable, Corrosive, Water/Air Reactive, Oxidizer, Explosive then email firstname.lastname@example.org so a separate container can be brought and picked up in a safer manner.
Plastic cannot be combined with glass in broken glass containers. If you have plastic wastes please email email@example.com for a waste container for plastic.
Email firstname.lastname@example.org with your building, room, the chemical(s) being used, whether it is a solid or liquid, current container size, amount of quantity being produced, frequency of production and suggestion of desired size.
They should be stored in a Satellite Accumulation Area over a secondary container (in case of spills) properly closed and labeled. If there is any flammable Hazardous Waste it should be stored in the flame cabinet.
For liquid waste it is NECESSARY to have secondary containment to ensure that no fluids goes down a sewage drain or even spread over the lab. A properly closed solids container is encouraged to have secondary containment.
No, Hazardous Waste containers must be kept tightly closed at all times, except when actively adding Hazardous Waste.
Any contaminated solids must be placed in a bucket with a proper label with the words “Hazardous Waste” at the top, then it should be followed by the list of chemicals they are contaminated with followed by “solids”.
NO!!! It is not permissible by federal regulations to take waste that is the end product of a process and treat it to render it “non-hazardous.” Also, federal regulations state the mixing of a hazardous waste with a non-hazardous waste creates waste which is still considered hazardous. So you cannot dilute a waste with water to make it non-hazardous.
Yes, inorganic acid waste may be mixed together providing the concentrations are similar (very concentrated acids such as 96% sulfuric acid must not be mixed with a very dilute acid 0.1% hydrochloric acid). Please include the percentage of each individual acid in the mixture on the Hazardous Waste label. Hydrofluoric acid must be stored and labeled separately from other inorganic acids whenever the process permits. Feel free to email email@example.com for any questions.
Yes, flammable solvent wastes can be commingled in the same Hazardous Waste container, but the percentage ranges must be listed individually for each constituent. Halogenated solvent wastes containing Fluorine, Chlorine, Bromine, and Iodine (e.g., methylene chloride, tetrachloroethylene, and trichloroethane), must be collected separately from non-halogenated wastes such as acetone, hexane, and ethanol. Feel free to email firstname.lastname@example.org for any questions.
Yes, simple treatment of hazardous waste to render it non-hazardous can be done; however the EHS office must be informed to ensure the product is non-hazardous. This can be done by emailing email@example.com.
