WASTE DISPOSAL GUIDE JUNE 2016

1.0 INTRODUCTION We are all aware of the importance of taking safety precautions when working with hazardous substances. Those risks do not simply disappear when the task is completed: They remain in the form of hazardous wastes. Proper hazardous waste handling is critical to the health and safety of the DePaul community. Our goal is to provide for the disposal of hazardous waste in a safe, efficient and ecologically sound manner. We need your cooperation to achieve this goal. To that end, Environmental Health & Safety (EHS) coordinates the disposal of hazardous and non-hazardous chemical, physical, biohazardous and radioactive waste. This guide contains procedures for safe handling and disposal. Please abide by the guidelines set forth in this document for all waste generated. For questions about anything related to waste disposal or recycling, please contact:

Katie Abma | (773) 325-8985 | [email protected] Finally, if you handle hazardous substances, know the hazards and how to protect yourself from them. Companion documents detailing regulatory requirements, risks, handling precautions and other safety related information are available on our Manuals and Procedures page (see Chemical Hygiene Plan, Controlled Substances Program and Radiation Safety Manual).

2.0 RESTRICTIONS

Employees shall not accept any hazardous substances as gifts or donations on behalf of DePaul without first obtaining approval from EHS prior to the transfer. This is to assure that no unanticipated future hazardous waste costs result from such a transfer. Employees shall not give, sell or otherwise transfer hazardous substances from DePaul’s possession outside of the procedures in this guide without the written preapproval of EHS. Hazardous waste shall not be poured down the drain or vented in any hood. This is especially true for solvents such as alcohol or acetone and corrosive substances. In the event that unlabeled, undated or otherwise unknown waste is generated, the department responsible may be required to cover the cost of testing and disposal. 3.0 HAZARDOUS WASTE DEFINED It is important to be familiar with the types of hazards exhibited by wastes you generate. The EPA places hazardous waste into 2 main groups: Characteristic and listed wastes. 3.1 Characteristic Wastes Characteristic wastes exhibit one or more of the following qualities:

• Corrosivity

3

WASTE DISPOSAL GUIDE JUNE 2016

Corrosive wastes are acids or bases (pH less than or equal to 2, or greater than or equal to 12.5) that are capable of corroding metal containers such as storage tanks, barrels and drums.

• Ignitibility

Ignitable wastes can create fires under certain conditions, are spontaneously combustible or have a flash point less than 140°F (60°C).

• Reactivity

Reactive wastes are unstable under “normal” conditions. They can cause explosions and generate toxic fumes or vapors when heated, compressed or mixed with air or water.

• Toxicity

Toxic wastes are those containing concentrations of certain substances in excess of regulatory thresholds which are expected to cause injury or illness to human health or the environment.

3.2 Listed Wastes Listed wastes are generated by specific industries and processes and are automatically considered hazardous based on the process that generated them regardless of whether they exhibit any of the “characteristic” qualities or not. DePaul does not generate much listed waste but because of some facility processes and our use of laboratory chemicals it is important to list them here.

• The F-list (Non-specific source wastes)

This list includes wastes from common manufacturing and industrial processes, such as solvents, that have been used in cleaning or degreasing operations.

• The K-list (Source-specific wastes)

This list includes wastes from specific industries, such as petroleum refining. DePaul currently does not generate any K-listed wastes.

• The P-list and U-list (Discarded wastes)

These are commercial chemical products that are considered hazardous when discarded. P-listed wastes are also called “acutely hazardous wastes” and are subject to more stringent regulation. A complete list of P-listed wastes can be found in Appendix A.

4.0 WASTE CONTAINERS AND STORAGE This section provides guidance on selecting appropriate containers for chemical waste. For information on physical, biohazardous or radioactive waste containers/storage, please see Section 6.0, Waste Streams.

WASTE DISPOSAL GUIDE JUNE 2016

4.1 Recommended Containers

• Flammable liquids/Acids/Bases: Glass bottles, high density plastic containers • Aqueous waste: Glass bottles, sturdy plastic bottles • Solid waste: Plastic/metal containers, thick polyethylene bags

Instead of ordering new containers, you can also create your own! We encourage the reuse of old bottles and containers. Often times, old Gatorade bottles, laundry detergent containers and other everyday household containers make perfectly fine waste containers. However, proper caution should be exercised before using homemade containers. Make sure they are compatible with the waste in question and only use bottles that have tight sealing caps and no leaks. If you have doubts about the container, err on the side of caution and use a new one instead. EHS can provide you with 5, 15, 30 or 55 gallon containers upon request. These can either be closed-top style with a bung for liquid waste, or open-top style for easier access and larger items.

If you need containers of a different size, contact your lab coordinator. They can direct you to resources on campus or assist you in ordering the correct supplies online.

4.2 Container Condition Waste containers must be in good condition. Leaking or damaged containers are not acceptable. If a container is leaking or damaged, place it in another container (second containment) and contact EHS for assistance. Containers should always have a properly fitting cap or other closer means. Makeshift covers such as tape to hold down a screw cap or a rag stuffed in an opening are unacceptable. Plastic bags, where acceptable as containers, should be double bagged, free of punctures or tears and tightly sealed. Bags shall not be used as primary or secondary containers for hazardous liquid waste. Containers should be inspected weekly for leaks and deterioration. 4.3 Chemical Compatibility Accidental mixing of wastes may result in dangerous chemical reactions. Generation of toxic gases, excessive heat, fire and explosions as well as overflowing and/or rupturing containers are possible consequences of such reactions. Proper precautions should be taken at all times when mixing wastes in containers. Do not mix any wastes whose compatibility you are uncertain about. Please see Appendix B for further guidance. 4.4 Empty Containers With the exception of P-listed wastes (which must be treated as if they were still full and disposed of properly via EHS), empty waste containers can be defaced and thrown away in the regular trash or recycled. Containers are considered empty when the majority of the chemical has been removed via common methods such as pouring, pumping, aspirating or draining. Residues left on the sides and bottom of the container are not typically considered to pose a hazard to human health or the environment. 4.5 Storage

5

WASTE DISPOSAL GUIDE JUNE 2016

We encourage you to utilize your hood as a satellite accumulation area (a temporary waste storage area) until containers are full or ready to be picked up and brought to a waste room. Designate an area of the hood to be used for waste, and use secondary containment. The total amount of hazardous waste that may be collected in a satellite accumulation area is 55 gallons, with the exception of acutely hazardous waste, of which there may only be 1 quart. Once these quantities are exceeded, you have 3 days to transfer the items to a waste room. Containers in satellite accumulation areas do not need to be dated. They can be stored there until the volume limit is reached. With that said, accumulating large amounts of waste in fume hoods is not recommended or conducive to fume hood performance. Please see the Fume Hoods Manual for more information.

5.0 ACCUMULATION TIME AND QUANTITY LIMITS DePaul is considered a small quantity generator (SQG) by the EPA. As a result, the University is allowed to generate no more than 2200 lbs. of hazardous waste in any calendar month and no more than 13,200 lbs. total hazardous waste on site for up to 180 days. Items in waste rooms (not satellite accumulation areas) must be labeled with the date they were placed in there. It is this date that starts the clock for the 180 day storage limit. 6.0 WASTE STREAMS DePaul has three main hazardous waste streams generated in laboratories: Chemical Waste, Physical Waste and Biohazardous Waste. Please refer to each section to learn more about each stream. 6.1 Chemical Waste It is important to label all chemical wastes properly. Every label must contain:

• The words “Hazardous Waste” • Owner/Lab # • Chemical contents

You may use your own labeling system if you wish. For convenience, waste labels like the one shown here are available in the Biology and Chemistry offices as well as by request from EHS.

Precautions should be taken to avoid the generation of unknown waste. Unknown waste can be a result of:

• Discarded/inherited chemicals • Bottle/label degradation • Lack of labeling on user-created bottles • Lack of communication between faculty/staff/students

6

WASTE DISPOSAL GUIDE JUNE 2016

Contact EHS or your lab coordinator at any time to have items transferred to one of our waste rooms. 6.2 Physical Waste Physical waste is any waste in solid form that is not considered chemical, biohazardous or radioactive waste. Physical waste includes gloves, towels, plastic, rags and sharps (broken glass, pipettes, slides, etc.) which are not contaminated. All of these items except sharps may be safely disposed of in the regular trash. Since sharps have the potential to puncture the skin, they must be disposed of in designated “broken glass” boxes. Sharps that are contaminated with chemicals must be labeled as such and

disposed of as chemical waste. Sharps that are contaminated with bodily fluids or other potentially infectious materials must be disposed of as biohazardous waste. 6.3 Biohazardous Waste A biological hazard (biohazard) is any biological agent or substance that poses a threat to living organisms. Common biohazardous wastes include but are not limited to:

• Materials contaminated with animal fluids • Petri dishes containing potentially harmful bacteria • Medical waste (i.e., waste generated in connection with the diagnosis, treatment or

immunization of human beings or animals, research pertaining to the provision of medical services or the provision or testing of biologicals)

• Basically anything that was alive at one time that has not been sterilized via chemicals or fixing agents

All biohazardous waste must be collected in red biohazard bags and red containers marked with the universal biohazard symbol. Never place trash or chemical waste in these receptacles.

EHS can provide you with large biohazard bags and 43 gallon biohazard bins (bio bins). If you require a smaller collection bin, please contact your lab coordinator. Containers used to store biohazardous waste must have a lid that is closed at all times. Items placed in bio bins do not need to be autoclaved unless there is reason to believe this should be done as an extra precaution. The contents of bio bins are autoclaved when they reach our contractor’s facility. It is acceptable to only autoclave glassware and other equipment you will reuse. If you do autoclave biohazard bags, do not overfill them and place

them in a secondary container. You may contact EHS at any time to pick up a full bin (whether EHS provided or not).

WASTE DISPOSAL GUIDE JUNE 2016

Bleach and other chemicals may be used to treat solid or liquid wastes to render them non-biohazardous. In this case, the waste is then considered chemical waste. Animal specimens in CarosafeTM or a similar preservative may be collected in lined barrels and disposed of via our chemical waste contractor, and should not be labeled biohazardous. 6.4 Radioactive Waste Please contact the Radiation Safety Officer for more information.

Dr. John Dean | (773) 325-2188 | [email protected] 7.0 RECYCLING Most empty containers, even with a little liquid at the bottom, are not considered hazardous waste. Before recycling or disposing of them, make sure that there are no labels indicating they are anything other than empty. Rip off labels, scratch out words, use dark markers or any tools at your disposal to render all markings unreadable. An exception to this is P-listed waste containers. Examples include pure samples of arsenic oxide, methyl hydrazine and sodium azide. Please see Appendix A for a complete list. Containers that held these substances must be disposed of as if they were full via EHS. 7.1 Batteries and Cell Phones EHS runs a battery and cell phone recycling program with many locations on campus: Lincoln Park Campus:

• Schmitt Academic Center 1st floor, by elevators near Kenmore entrance • Ray Meyer Fitness & Recreation Center, front desk • Student Center, 1st floor near information desk • McGowan South, 1st floor near Belden entrance and the Environmental Science & Studies

department, Suite 203 • John T. Richardson Library, Kenmore entrance • Housing Services, Centennial Hall Suite 301 • School of Music, ground floor near bulletin boards

Loop Campus:

• DePaul Center, 1st floor near security desk and elevators
