2 Hazardous Waste Management Learning Objectives The generator of hazardous waste will be able to:Identify hazardous wasteEnsure it is properly managed188.8.131.52.
3 Hazardous Waste Module State and federal regulations require that employees who produce (generate) hazardous waste must be trained.This module has been developed to meet this expectation.
4 Hidden Hazards Dangerous chemicals in school labs an explosive situation By Katheleen Conti, Boston Globe Staff | April 10, 2005Chemistry lesson one: Accidents happen, like the recent spill at Exeter High School in New Hampshire, when fumes in a lab class sent three students to the hospital and shut down the school for the day.Chemistry lesson two: Adding unknowns to the mix -- like improper storage and handling of toxic substances -- can be a formula for disaster.In January, firefighters responding to an alarm triggered by a chemistry experiment at Pope John XXIII High School in Everett found a jar containing a potentially volatile material that is used to produce rocket fuel. Deemed unstable, the chemical -- 2, 4-dinitrophenol -- was detonated by the State Police Bomb Squad.
5 Chemicals Ordered Removed By Tarron Lively, THE WASHINGTON TIMES, Published March 25, 2005D.C. Public Schools Superintendent Clifford B. Janey issued a protocol yesterday for removing potentially dangerous chemicals from schools, after a series of mercury contaminations and the revelation that a previous removal effort was incomplete. The nine-page protocol lists more than 200 chemicals including mercury, chlorine, chloroform, ether, hexyl alcohol and nicotine. The protocol was issued to the principals of each of the city's roughly 150 public schools. The school system's Hazmat Removal Team, D.C. Fire and Emergency Medical Services and the American Association for the Advancement of Science helped create the protocol and will handle the removal and disposal of the materials. School administrators ordered all potentially hazardous materials removed after an October 2003 mercury spill at Ballou High School in Southeast. The incident closed the building for more than a month, and cleanup cost at least $1 million. A student who was charged in the case had taken the mercury from a science lab. However, investigations into the recent mercury incidents at Cardozo High School and Hardy Middle School revealed that potentially hazardous materials were still inside schools.
6 Recently In Colorado, 300 schools were inspected. They Reported: 99% had inherited their inventories 98% had incompatible storage 94% had shock sensitive compounds 85% had inadequate chemical hygiene plans 65% had inadequate functioning fume hoods 30% had explosive chemicals 15% had radioactive materials
7 The EPA “Reaches Out”In February 2007, EPA Region 4 launched the Colleges and Universities Compliance Incentive Initiative, encouraging.Region 4 mailed letters to public and private colleges in the southeastern United States to “highlight the opportunity to take advantage of voluntary environmental self-audits” .This provides incentives for schools to voluntarily discover, disclose, and correct non-compliance.Disclosures may receive a partial or complete reduction in financial penalties.
9 Summary of Incentives under EPA’s Audit Policy Penalty mitigationNo recommendation for criminal prosecution.No routine requests for audit reports.
10 EPA seeks $171,050 from Plymouth State University, Plymouth, NH for Hazardous Waste Violations Contact: Sheryl Rosner, EPA Office of Public Affairs, (617)For Immediate Release March 3, 2005; Press Release #sr050301The U.S. Environmental Protection Agency announced today that it has proposed a $171,050 penalty against Plymouth State University, in Plymouth, NH for violations of hazardous waste laws. ….Specifically, EPA claims that the University failed to:make hazardous waste determinations;properly store hazardous waste;maintain spill and fire control equipment;post “no smoking” signs;post emergency telephone numbers;keep hazardous waste containers closed;mark hazardous waste containers with accumulation dates;conduct inspections of hazardous waste storage areas.
11 EPA Cites Puerto Rico University at Mayaguez for Multiple Violations of Environmental Safety Rules Wednesday, October 5, 2005The U.S. Environmental Protection Agency (EPA) has cited the University of Puerto Rico (UPR) in Mayagüez for violating EPA Regulations… and proposed that the university pay nearly $1 million in penalties for these violations. …….UPR submitted self-disclosures under EPA's Audit Policy … Normally, EPA would grant relief from financial penalties for self- disclosed violations, but it was determined that UPR was not eligible for full relief because UPR was not correcting all its violations. As a result, EPA conducted its own comprehensive inspection .. and found numerous violations.EPA and the Commonwealth found that UPR failed to operate its facility in a manner that would minimize the risk of releasing hazardous wastes … The containers held wastes ranging from used oil, various acids and spent solvents to formaldehyde. UPR was also storing hundreds of containers of old and expired chemicals, such as picric acid, in an unsafe manner.
16 Compliance Tips Helpful Tip #1: How do you tell whether it’s waste? Is it in good condition and labeled?Is it currently legal for use in the U.S.?Has anyone used it in the last year or two? Be honest.Will anyone use it in the next year or two? Be brutally honest.
17 Compliance Tips Helpful Tip #2: How old is that bottle? Plastic Screw Caps: 1912Fisher Scientific incorporated: 1926ZIP codes: 1963CAS numbers: 1966You DO date your bottles, don’t you?If it has a cork, it’s older than 1912.If the bottle says Eimer, it’s older than 1926.
28 Hazardous Waste 101 How do you tell? Ask the vendor Use the MSDS Book Use the MSDS Online
29 Hazardous Waste Examples of hazardous waste: Mercury from a broken thermometerAcetonitrile from HPLCEthidium bromideFlammable Paints and SolventsWaste isopropyl alcoholAerosolsElectronic circuit boards (lead solder)
30 Hazardous Waste Locations Laboratories and ClassroomsMaintenance Facilities (paint, pesticides, maintenance fluids)Light BulbsNursing Schools / Health ServicesBuildings repurposed from science curriculum
33 Management of Chemical Waste Separate incompatible materialLabel Each Waste ContainerSeal each waste containerKeep track of constituents (rough quantities)Store waste in appropriate locations (cabinets, not in active hoods)
34 Proper Labeling All waste containers must be properly labeled. Hazardous Materials Must have the words “Hazardous Waste”“Used Oil”“Universal Waste -- Lamp(s),” or “Waste Lamp(s),” or “Used Lamp(s)",Must include all hazardous components
36 Improper Methods of Disposal for Hazardous Waste Hazardous waste should not be:Placed In regular trashMixed with biohazard waste (red bag or sharps)Flushed down the drainAllowed to reach surface water (rivers, lakes) via storm sewer systemAllowed to evaporate (note - open containers imply evaporation)
38 Satellite Accumulate Area Satellite accumulate area – is defined as the area (typically a room) where the hazardous waste is generated.Must be designated with signsContainers must remain closed except when adding material.Containers must be marked with the words “Hazardous Waste”.
39 Satellite Accumulation Area Can accumulate up to 55 gallons of hazardous waste or a maximum of one quart of acutely hazardous wasteMay need to segregate chemicals and provide secondary containmentDo not date hazardous waste label until the container is moved out of lab
41 Reduction of Chemical Waste Replace reagents with less toxic alternatives (green chemistry)Work in smaller scalesCentralize purchasingBuy only what you need for 1 yearSupervise what is coming into stockNeutralize acids and bases (not chromic or fuming acid)
42 Containers Contents must be compatible with container material Problems:Certain solvents placed in plastic containersHydrofluoric acid in glass containers
43 Containers Do not mix incompatibles that will produce: Heat Violent reactionsFire/ExplosionFlammable or toxic gases
44 Empty ContainersEmpty containers that once held a hazardous material may be placed in the regular trash.Containers that held acutely toxic materials (selected list from EPA) are considered hazardous waste and may not be placed in regular trash.
45 Empty Container Definition An empty container is defined as:All waste has been emptied using common practiceMaximum of 1 inch of product remains in containerNo more than 3% by weight of the container remains (tanks <110 gallons)
47 Summary of Most Common Violations Waste containers were not marked “Hazardous Waste”Waste Containers without dates of accumulationWaste Containers are not closedUniversal waste light bulbs were not being managed properlyTraining of employees who handle hazardous waste is not documentedInspections were not recorded on a weekly basisOnsite Treatment of wastes is occurring.Waste material has not been determined as being hazardousNot all MSDS’s
50 Liabilities = Injury to Students / Personnel Violations can be up to $5,000 eachWillful NeglectRepeat OffensesViolations with Immediate Threat to Human Health or Environment - $25,000Unreported spills, Dumping, Misrepresentation=
52 LabelingBe certain to label all containers including date of receipt or formulation. Ink should be waterproof and fade resistant.Must have accurate chemical inventory and MSDS’s accessible throughout school.
53 ArrangementPlacement of the items on a stockroom shelf should be based upon compatibility--not alphabetical succession.Ammonium nitrate + acetic acid mixture will ignite especially if acid is concentratedCupric sulfide + cadmium chlorate explode on contactSodium + sulfur reaction proceeds with explosive violenceSodium cyanide + sulfuric acid release of HCN gas, death vigorous reaction, highly exothermicThe Flinn Scientific Catalog has an excellent system to store chemicals based upon their compatibility.
57 Large ContainersLarge containers should be avoided by ordering chemicals in the smallest practical size. (The initial cost savings are not worth the disposal costs and liability.)They should be placed on lower shelves.
58 Flammables / Acids / Bases Storage Flammable liquids should be stored in safety cabinets.Appropriate cabinets for Organic Acids, Inorganic Acids (at least separate trays in cabinet), and Nitric Acid should be used if volumes appropriate.Bases need to be stored separately.
65 Chemicals to RemoveAnything not used last year this year or next year.Reactive ChemicalsHygroscopic (Wet) ChemicalsLow molecular weight organicsStrong OxidizersOlder than 10 yearsPoor packaging (repackage?)Unlabeled / Unknowns
66 Inspections Should occur often and be recorded. Looking for material that may be leaking, not properly closed, or out of place.Annually the shelves should be examined and any chemicals disposed of that will not be used in the next year.
