1. Environmental Health & Safety(303) 492-6025ehs@colorado.eduA Division of The Department of Public SafetyUniversity of Colorado, Boulder Hazardous Chemical Management Training

2. Why am I here? 1) Someone said I had to be here 2) I work with potentially hazardous materials 3) I’d like to help minimize pollution 4) I live for the University and desperately want to protect its assets and investments

5. Resource Conservation and Recovery Act (RCRA) - Passed by Congress in 1976

6. RCRA-Designed to Protect our Soil and Water From Improper Hazardous Waste Handling and Disposal

7. HW Regulation is Designed to Control the Management of HW from “Cradle to Grave”

9. Talking about my Generation • If you produce a waste that is hazardous by definition or characteristic, you are a generator. • If you’re a generator, you must have ANNUAL training.

20. Chemical InventoriesOverall sense of hazardsHelp minimize hazardous material • Initial Inventory & Update • Storage Strategies • Secure Hazardous Chemicals • Minimize Stock

21. Chemical InventoriesOverall sense of hazardsHelp minimize hazardous material • CDPHE - Peroxides, ethers, Grignard reagents, perchloric acid, di/tri-nitros (picric acid) • Expiration dates • DO NOT OPEN suspicious containers (discoloration, crystals, age) - Call EH&S

25. Grignard Reagents

26. Shock Sensitive Peroxides

28. Emergency Action Plan • Post Your Emergency Contingency Plan; Customize • Know Location of: Alarm Stations Eyewashes / Showers Fire Extinguishers Exits MSDSs Spill Equipment

29. Incidental Spill Clean Up • What is an Incidental Spill vs. an Emergency Response? • What are the Steps of a Clean Up? Stop source of leak Warn your neighbors Contain spill Clean up the spill using proper protection (PPE) Dispose of waste properly Remember to notify your supervisor

30. Emergency Spill Scenario • You have just dropped 5 gallons of toluene on the floor of your lab. Some has splashed on one of your coworker’s arms and clothes. What do you do now?

31. Emergency Spill Response • Life Safety First • Evacuate Immediate Area • Pull Fire Alarm • Call 911 From Safe Location • Remain Available for Emergency Personnel

32. Fires Is there such a thing as a small (uncontrolled) fire? • Follow Emergency Spill Response Procedure • Attempt to extinguish the fire if you’re comfortable doing so

33. EPA Regulations (Cont.) • Pollution Prevention and Waste Minimization • Keep Separate (hazardous and non-hazardous wastes) • Substitute • Toluene For Benzene • Non-Mercury Thermometers • Water Aspirators • Scale Reduction • Don’t Over Purchase • Cost of Chemicals & Cost of Disposal

35. Hazardous Waste Storage Hazardous Waste Satellite Accumulation Area (SAA) Room Number _____

36. Hazardous Waste Storage Special Designated Waste Storage Areas (SAA) • In “Secured” Area • Near Generation Point • Appropriate Containers • Compatible with contents • Containers must close and seal For example: original chemical containers, 19L plastic carboys, drums

37. Chemical Waste Storage

38. SAA Checklist - 1 • Labeled, “Hazardous Waste” • Closed and Not Leaking or Bulging • In-Process • Leave Head Space 3 inches in carboys • Pressure Relief

39. SAA Checklist - 2 • Separate to Prevent In-compatibility • What Groups Can You Think Of? • Oxidizers away from Flammables • Acids away from Bases Hazardous Waste

40. SAA Checklist - 3 • In Secondary Containment- • Tubs and Trays • Not Just Waste Hazardous Waste

42. SAA Checklist - 4 • Total in SAA Must Be Less Than 55 Gallons • Does Anyone Have This Much Waste? • Request Pick-Ups Often • Minimize Accumulation • (If you’re still awake, nudge the sleeping person next to you) Hazardous Waste

43. SAA Checklist - 5 • Must Have Less Than 1 Quart of Acutely Toxic Waste • Any dilution, or impurities void this requirement • Call EH&S, before designating as waste • Must leave area within 24 hours Hazardous Waste
