1. Management of Stock Chemical Purchase only quantities that can be used in a reasonably short time. Limit amounts kept in Labs/Work areas –Store according to chemical classification –Do not store alphabetically –Store in closed cabinets Know the quantities and types of chemicals you have Keep containers properly labeled and closed at all times Prepare for chemical spills and accidents Regularly inspect the stockroom

2. Waste Management o Generation and identification o Accumulation areas o Packaging and labeling o Pickup procedures o Storage areas o Disposal procedures

3. Generation and Identification of Hazardous Wastes

4. Identifying Hazardous Wastes

5. Two Types of Hazardous Waste o Listed in 6 NYCRR 371.4 o Characteristic

6. Listed Hazardous Wastes o F List: wastes from certain common industrial or manufacturing processes Example: spent Perchloroethylene used as solvent o K List: wastes from certain specific industries Example: petroleum refining wastewater treatment residues o P and U Lists: discarded chemical commercial products (applies only if chemical is discarded unused)

7. Characteristic Waste o Ignitable waste (flash point<140º F) examples: alcohols, acetone, toluene, xylene, WD-40 o Corrosive waste (pH 12.5) examples: acids, rust removers, hydroxides, caustics, drain cleaners

8. Characteristic Waste (cont.) Reactive waste undergoes a violent or abnormal reaction in the presence of water or under normal ambient atmospheric conditions. Among this type of hazard are the pyrophoric liquids which will ignite in air at or below normal room temperature in the absence of added heat, shock or friction, and the water-reactive. flammable solids which will spontaneously combust upon contact with water. examples: picric acids, ethyl ethers, sulfide wastes

9. Characteristic Waste (cont.) Toxicity characteristic: laboratory test (TCLP) that creates a liquid leachate that is similar to what would be expected from a landfill examples: wastes with heavy metals, Volatile Organic Compounds (VOCs)

10. Mixture and ‘Derived-From’ Rules o Treatment residues are hazardous only if they exhibit hazardous waste characteristics Example: neutralized sulfuric acid Characteristic Waste

11. Waste Management Ødetermine a hazardous waste Øadd hazardous waste to a container Ømove or transport a hazardous waste Øinspect hazardous waste areas Ørespond to spills of a hazardous waste

13. How to Manage Waste Any abandoned chemical is waste Any chem. waste that is EPA listed Any chem. waste that meets EPA’s characteristic rules

14. Abandoned Chemicals

15. Storage

16. General Requirements Only trained personnel may manage hazardous wastes Waste must be kept in a Satellite (Hazardous Waste) Accumulation area that is close to where waste is generated and under control of supervisor No hazardous waste may be dumped down the drain or discarded with garbage Wastes must be placed in proper containers Wastes may be added to proper containers until approx. 80% full at accumulation area Waste containers must be placed in a secondary spill “container” to catch any potential spills Wastes must be labeled with “Hazardous Waste Stickers”

17. Satellite Accumulation Area (SAA)

18. ‘Satellite’ Storage RCRA regulations allow a generator to accumulate hazardous waste at or near the point of generation if certain requirements are met.

19. Compliance Assistance

20. Containers Definition: portable devices in which a hazardous waste is stored, transported, treated, disposed of, or otherwise handled.

21. Container Requirements oin good condition ocompatible with waste okept closed except when being filled or emptied ohandled in a safe manner omarked with the words “Hazardous Waste” and the words describing the contents, DO NOT use chemical formulas oNOTE: incompatible waste containers must be separated from one another Containers must be:

22. Pick Up Procedures oWritten procedures oDriver must be trained oHave spill cleanup material available oPlace bottles in a tray in a cart, use “acid bucket” for acids and bases oWaste must be secured in vehicles

23. Storage Areas oFor LQGs (>1000 lb/mo): 90 day limit before shipment oFor SQGs (>100 <1000 lb/mo): 180 day limit before shipment oContainers must be in good condition & kept closed oProper labeling required, including date oInspected weekly oEmergency equipment & communications

24. Inspections (SAAs) SAAs should be routinely inspected (i.e., on a weekly basis) by the designated lab or work area waste coordinator Use the inspection form provided by the EHSO Return completed forms to the ESHO

25. Inspections (Storage Areas) Required weekly for LQGs and SQGs Use the inspection form provided by the EHSO. Return completed forms to the ESHO Items to include: spills, leaks, container condition, containers caps in place, readiness of emergency equipment, separation of incompatible wastes, signage present

26. Universal Wastes oGenerated in a wide variety of settings, not only industrial oGenerated by a wide community oPresent in significant volumes in non- hazardous systems oExamples: â batteries â pesticides â thermostats â hazardous waste lamps

27. Regulated Medical Wastes Regulated Medical Waste: waste generated in the diagnosis, treatment, or immunization of human beings or animals including the following: o Infectious animal wastes o Human pathological wastes o Human blood and blood products o Needles and syringes o Cultures and stocks

28. RMW Packaging o Sharps â disposed of in red, rigid, puncture- and break- resistant, leak proof container o Liquids & Non-Sharp Solids â disposed of in red bags which are impervious to moisture and have strength sufficient to resist tearing under normal conditions of usage and handling

29. Radioactive Waste Management o Generation, storage, transportation, and disposal is governed by federal, state, and local agencies o Disposal options are limited and costly o Minimize waste generation

30. All radioactive waste generated at Hunter must be o Stored in a “Controlled Area” o Properly stored and packaged o Properly shielded o Properly documented o Properly labeled o Properly segregated Radioactive Waste Guidelines

31. Used Oil oNYSDEC presumes used oil is recycled unless disposed oUsed oil mixed with hazardous waste is regulated as a hazardous waste oUsed oil mixed with an ignitable characteristic waste (e.g. mineral spirits) can be managed as a non-hazardous waste if the Flash Point is > 140º F oMaterials contaminated with used oil, if properly drained, are not used oil (the drained oil is regulated as used oil)

32. Compressed Gas Cylinders oReturn to vendor, or oContact EH&S Office for assistance

33. Mercury Waste oReplace thermometers and measuring instruments containing mercury with equipment that uses non-hazardous fluids or electronic devices oContact EH&S Office if mercury spill occurs oContact EH&S Office prior to generating mercury waste mixtures in order to develop a strategy for waste minimization and disposal

34. “e-wastes” (i.e., computer components, laboratory instrumentation)

35. Spills and Emergencies oIN THE EVENT OF A SPILL lExtinguish all sources of ignition lIsolate incompatible materials lAttempt to stop or contain the release at the source – PROVIDED THIS CAN BE DONE SAFELY lIsolate receptors such as floor drains, sumps, soil, and runoff areas

36. Spills and Emergencies oMinor chemical spill - less than 1 liter lnotify others in the area lavoid breathing fumes lcontact EHSO (Ext. 4462) & Campus Security (Ext. 4444) lassess the size, toxicity, hazards of the spill lprovide adequate ventilation llocate clean-up materials luse proper PPE and safety equipment
