Slide1: 

Department of University Safety & Assurances, Office on Environmental Affairs www.safety.uwm.edu

Who is a Hazardous Waste Generator?: 

Who is a Hazardous Waste Generator? Anyone on campus who generates hazardous waste that must be picked up by University Safety and Assurances (US & A) is a Hazardous Waste Generator US & A picks up the waste from generators and brings it to the central hazardous waste accumulation facility

Goals: 

Goals Recognize a hazardous waste Know the UWM hazardous waste rules Recognize other special wastes

What is hazardous?: 

What is hazardous? Items received with hazardous shipping labels will most likely become hazardous waste

What is hazardous?: 

What is hazardous? Check the Material Safety Data Sheet (MSDS) to help determine if your chemical is considered hazardous

What is hazardous? : 

What is hazardous? Flammable Inflammable Flashpoint (<140 F) Corrosive, Acid, Basic, Caustic Explosive Stench Agent Oxidizer Water or air Reactive, Pyrophoric, Peroxide Former Poison Any of these keywords usually indicate the waste materials will be hazardous waste:

Keywords not necessarily indicating hazardous waste: 

Keywords not necessarily indicating hazardous waste Irritant Desiccant Intumescent Vapors Harmful Keep away from children Carcinogen, Mutagen, Tetratogen, Oncogen, Cancer-causing, Cancer-promoter Poison

EPA’s “P-Code” List: 

EPA’s “P-Code” List Substitute with a less hazardous chemical Keep P-wastes separate from other wastes Inform University Safety & Assurances if you use a chemical that will become a P-listed waste EPA’s list of “P-Waste” can be found at URL: http://www-adm.pdx.edu/user/pcc/plist.htm EPA List of “P-Code” Waste

Empty Containers: 

Empty Containers If it is a "P" waste we should get the empty container Otherwise the empties can be tossed in the “normal trash”

Hazardous waste disposal rules: 

Hazardous waste disposal rules 1. Minimize Waste 2. Collection and Storage 3. Label 4. Do not store hazardous waste in public areas

Rule 1. Minimize Waste: 

Rule 1. Minimize Waste By law, a Waste minimization program is required. Among ways this goal is accomplished is by: Source reduction (ordering less) Surplus chemical redistribution Labeling all containers (disposal of unknowns is expensive) Using mercury-free instruments Substituting hazardous chemicals with non-hazardous chemicals Using secondary containment

How you can help minimize costs: 

How you can help minimize costs Bulking (mixing) Compatible waste solvents are mixed into a 55 gallon drum for a fuels blending program, at a significant cost savings Let us know if there is anything that may not be compatible

How you can help to minimize waste: 

Neutralizing Acids: Acidic waste can be sewer disposed after neutralization, but we need to know what else may be in it -- i.e: Heavy Metals (like Mercury, Lead, Chromium, Cadmium, Selenium or Barium), Flammable Liquids and Poisons Acids with other regulated hazardous ingredients can NOT be sewer disposed How you can help to minimize waste

Rule 2. Collection and Storage: 

Rule 2. Collection and Storage For most liquid wastes, we prefer to use the two gallon carboys which we provide Larger or smaller containers can be provided if needed These carboys are lightweight, sturdy, chemical resistant, easy to label and have a nice handle which allows for easy transportation

Waste Containers: 

Waste Containers Chemical waste generated at UWM is kept in a container until it’s shipped for disposal The chemical waste is collected by Environmental Affairs personnel and stored for no more than three months Be sure waste chemicals are compatible with the container.

Keep waste containers closed: 

Keep waste containers closed Keep waste containers closed except when adding waste

Containers: 

Containers Chemical waste in general, and hazardous waste in particular, must be stored in a sturdy container, free of leaks Do not ask us to pick up open containers of chemicals

Secondary Containment: 

Secondary Containment To contain hazardous waste if the container leaks, the hazardous waste container should be kept in secondary containment such as a tray or tub

Containers: 

Containers Cans of paint without lids, leaky ballasts, broken thermometers and chemically contaminated items must be overpacked into a container

Rule 3. Labeling: 

Rule 3. Labeling Labeled waste containers are required by law So Environmental Affairs knows how to process it Because Environmental Affairs staff cannot pick up unknowns Because unknowns are very expensive to ship for disposal

When should you label your waste container? : 

When should you label your waste container? The DATE waste was first put in the container must be on the label along with the name of the chemical As EACH NEW waste is put into the carboy, the name of that chemical is to be added to the label

Designate a Location for Your Waste: 

Designate a Location for Your Waste Signs have been posted in rooms where hazardous waste will be picked up to designate the location for collection of hazardous waste

Unknowns: 

Unknowns are chemicals in containers where the labels have been lost or the name of the chemical on the label is obliterated Unknowns

Unknowns...: 

Unknowns... Should not occur in your area because you always label everything Cost more to dispose

Unknowns: 

Unknowns Unknowns must be handled as hazardous, flammable, toxic, and reactive materials until we can narrow down the identity Unknowns are not permitted in our hazardous waste facilities Our clients have to hold on to their unknowns until the next shipment date

Labeling: 

Include anything unusual on the label, even if in small quantity (examples: reactive and explosive chemicals, PCBs, dioxins, extremely toxic chemicals, etc.) Labeling

Labeling: 

Labeling Don't use chemical symbols, abbreviations, or codes for waste identification

Rule 4. Do Not Store Hazardous Waste in Public Areas: 

Rule 4. Do Not Store Hazardous Waste in Public Areas Designate an area in your office or laboratory, under your control, to accumulate hazardous waste Do Not leave hazardous waste in public spaces, this is a safety hazard Call Environmental Affairs if you need a waste pickup

Special Wastes: 

Special Wastes Check our web page to identify what to do with Special Wastes

Special Wastes: 

Special Wastes Special Hazardous Wastes, should be separated from other wastes, and not be put into normal trash, or solid waste dumpsters Some examples of these special wastes are identified in the following slides

Aerosol Cans: 

Aerosol Cans Aerosol cans may be considered Hazardous Waste if one or more of the following conditions exist: The can is still pressurized The propellant is chlorinated The propellant is isobutane, ether or some other flammable gas The material contains lead, pesticides or another hazardous constituent

Asbestos: 

Asbestos Asbestos removal and disposal is highly regulated Questions regarding UWM’s asbestos program should be directed to Facilities Services at x4576

Ballasts: 

Ballasts Check the label on each ballast, if the label says "No PCBs“ then the ballast(s) can be disposed as normal trash If the label doesn't say "No PCBs" then assume it has PCBs and call for a waste pick-up

Batteries: 

Batteries Alkaline batteries can go into the regular trash All other batteries can be recycled by Environmental Affairs

Biohazardous Materials: 

Biohazardous Materials Autoclave or sterilize with an appropriate method

Capacitors: 

Capacitors Capacitors are used in electrical equipment and can contain PCBs, which are regulated upon disposal

Carcasses: 

Carcasses Carcasses for disposal are generally sent to a rendering firm for reclamation. These items are frozen until picked up by a rendering service

Circuit Boards: 

Circuit Boards Unneeded circuit boards and articles containing circuit boards are not appropriate for normal trash disposal Circuit boards contain lead, mercury, arsenic and other heavy metals

Compressed Gas: 

Compressed Gas Containers of compressed gas go by many names, including gas cylinders, lecture bottles and high pressure tanks These containers of gas, even when empty, are likely to contain a residual of at least one atmosphere of the gas

Dioxin and Dioxin Precursors: 

Dioxin and Dioxin Precursors Please keep all dioxin and dioxin precursor waste separate from other chemical waste and from other non-hazardous waste Please maintain separate waste containers for dioxin waste

University-Owned computer equipment can be recycled through Environmental Affairs: 

University-Owned computer equipment can be recycled through Environmental Affairs Electronics

Empty Drums and Containers: 

Empty Drums and Containers Contact Facilities Services (x5216) to request a pickup of empty drums Drums must be completely empty before they can be pickup and transported

Explosives: 

Explosives The disposal of explosive and reactive waste materials needs to be handled more carefully than other hazardous waste The identity and concentration of waste constituents are more critical than for other types of hazardous waste

Fixer Waste: 

Fixer Waste Silver is reclaimed from photographic fixer both electrolytically and through a steel filter Contact x4999 or x2883 to schedule a pickup

Fluorescent Lamps : 

Fluorescent Lamps Fluorescent lamp disposal is an environmental concern due to the presence of mercury within the tube Burned out and unneeded lamps may be handled either as hazardous waste or as recycled waste

Freon: 

Freon Freon and ozone depleting chemicals must be reclaimed and recycled Keep Freon-contaminated oils separate from other oils

Highly Hazardous Chemicals: 

Highly Hazardous Chemicals Keep these items separate from other hazardous wastes. Do not mix these items with other wastes Do not store your waste chemicals longer than necessary

Laboratory Glass: 

Laboratory Glass Broken glass and glass which could potentially break and become a cut or puncture hazard must be carefully packaged before being put in the trash Place glass in sturdy box and label “broken glass” then toss in dumpster

Lead Paint: 

Lead Paint Any generator of lead paint debris must follow the state's solid waste regulations and dispose of the debris in a DNR approved disposal facility

Mercury: 

Mercury Mercury should be kept separate from other wastes

Non-Hazardous Chemicals: 

Non-Hazardous Chemicals If the chemical is not regulated and is not significantly toxic, or another known human health or environmental hazard, the item may be disposed by sewer or normal trash disposal

Oil: 

Oil Oil is disposed or recycled depending on whether the oil is contaminated with any hazardous constituents

Oil-Filled Equipment: 

Oil-Filled Equipment PCB fluids have long been associated with oil filled switches, capacitors and transformers Certain hydraulic equipment is known to contain PCBs

Paint: 

Paint Usable, unneeded paint is collected and donated to various non-profit agencies

Reactive Chemicals: 

Reactive Chemicals Reactive chemicals are defined as those substances which can, in contact with air, water or other common substances, vigorously or violently give off heat, energy or toxic gases or vapors

Sharps: 

Sharps Put sharps into a puncture-resistant, leak-proof, sharps container Label the container with the word, "SHARPS“ Containers are available through Environmental Affairs

Sharps: 

Sharps Decontaminate (autoclave or chemically disinfect) if contaminated with infectious agents, blood, or other body fluids

Tires: 

Tires At UWM, the fleet garage handles the disposal of old tires for University-owned vehicles

Toner Cartridges: 

Toner Cartridges Most spent, used, or unneeded toner cartridges are not regulated as hazardous waste Some toner comes in liquid form, which is likely to contain flammable solvents The hazardous waste program handles disposal of liquid toner cartridges

Transformers: 

Transformers Electrical transformers come in two categories, “wet” and “dry” The “dry” type is generally not a disposal problem The “wet” type may contain oil which contains PCBs

Radioactive Waste: 

Radioactive Waste Questions regarding disposal of radioactive materials should be directed to the Radiation Safety Program (Sharron Daly, x4275)

Unknowns: 

Unknowns When we pick up unknowns on shipment day, our hazardous waste contractor runs a series of tests to determine the proper shipping class so it can be sent to a disposal site The extra time and handling adds significantly to the cost of disposal

Water Reactive Chemicals: 

Water Reactive Chemicals Water reactive materials can react violently or vigorously in contact with water, wet surfaces or even the moisture in the air These chemicals may react to give off a flammable gas or a toxic gas or spontaneously burn or explode

White Goods: 

White Goods White goods may contain hazardous components such as PCB capacitors, sulfur dioxide, ammonia and freons Call Facilities Services for Disposal/Recycling, x6272

Where Does it Go? : 

Where Does it Go? Every two months, a chemical waste contractor picks up waste from our accumulation sites and ships the waste to various disposal facilities in the US and Canada
