  2. Waste Management Question 1: Your HCl acid bath used to clean glassware has become dirty and it is time to change it. The spent HCl acid waste meets the characteristics of which of the following? Review Corrosivity Reactivity Ignitability Toxicity The spent HCl acid waste meets the characteristics of Corrosivity.

  3. Waste Management Question 2: You have a spent gel that contains 10 mg/liter of a spent mercury compound HgCl2. Approximately how many parts per million (ppm) of mercury does the gel contain? 1 ppm 2 ppm 10 ppm 100 ppm The spent gel contains 10 ppm of mercury. .

  4. Waste Management Question 3: Does the spent gel from above have to be disposed through Environmental Health and Safety as a "toxic" hazardous chemical waste? Yes No The spent gel contains 10 ppm of mercury, which exceeds the 0.2 ppm Hg standard. Therefore the spent gel needs to be disposed of through Environmental Health & Safety as a "toxic" hazardous chemical waste. . .

  5. Emergency Response Question4: If 100 milliliters of diluted sulfuric acid spills, would it be treated as an incidental or emergency response spill? Click on the correct response. Incidental Emergency Response Correct! This is an incidental spill that can be neutralized and cleaned up by an individual with the proper training. Incorrect. This is probably an incidental spill unless the acid was going down the drain or caused an injury. You can neutralize the spill and clean it up.

  6. Emergency Response Question 5: What if the spill was 4 liters of ethanol? Would you treat this as an incidental or an emergency response spill? Incidental Emergency Response Incorrect. This is probably not an incidental spill because the fumes from this much ethanol could create a flammable hazard. Correct! The fumes from this much ethanol could create a flammable hazard.

  7. Emergency Response Question 6: Let us review the "Spill Rule" concepts Directions For each spill rule, choose its correct purpose. Spill Rule: Ask Yourself "Can I Handle It?“ The procedure to handle emergency response spills. The criterion to distinguish emergency response spills from incidental spills. The procedure to handle incidental spills.

  8. Emergency Response Spill Rule: Ask Yourself "Can I Handle It?“ The criterion to distinguish emergency response spills from incidental spills. Correct! If you know how to handle it, you: deal with the hazards of the chemical without harming yourself, others or the environment; have enough cleanup materials for the volume spilled; have correct protective equipment; be trained to clean up the spill.

  9. Emergency Response Question 7: Let continue our review of the "Spill Rule" concepts Directions For each spill rule, choose its correct purpose. Spill Rule: 4W: Warn, Wear, Wipe Up, Wrap Up To handle emergency response spills. To distinguish emergency response spills from incidental spills. The procedure to handle incidental spills.

  10. Emergency Response Spill Rule: 4W: Warn, Wear, Wipe Up, Wrap Up To handle emergency response spills. To distinguish emergency response spills from incidental spills. The procedure to handle incidental spills. Incorrect. In fact, once you determine the spill is an emergency response spill, you should take the Warn, Lock, Report and Wait steps, not the 4W procedure.. Incorrect. Actually, this is what you always do first of all - determine what kind of spill you have to deal with. Try to think what kind of spill you would choose to follow the 4W set of procedures for. Correct.

  11. Emergency Response Question 8: Let continue our review of the "Spill Rule" concepts Directions For each spill rule, choose its correct purpose. Spill Rule: Warn, Secure, Report, Wait To handle emergency response spills. To distinguish emergency response spills from incidental spills. The procedure to handle incidental spills.

  12. Emergency Response Spill Rule: Warn, Secure, Report, Wait To handle emergency response spills. To distinguish emergency response spills from incidental spills. The procedure to handle incidental spills. Correct! Warn, Secure, Report and Wait are the four steps you would definitely use to handle emergency response spills. Incorrect. To distinguish emergency response spills from incidental spills is what the "Can I Handle It?" rule dictates. Think when you would take the Warn, Secure, Report and Wait steps. Incorrect.

  13. Waste Management Question 9: If you are unsure about whether or not the chemical you are working with exhibits any of the CRIT characteristics for hazardous waste, what should you do? Review the chemical's safety data sheet (SDS). Review the original purchase order. Call the Colorado Department of Public Health & Environment (CDPHE). Review the shipping document. You should review the chemical's SDS. The SDS is available from the manufacturer's or supplier's web site. Be careful because only ingredients at a concentration of 1% (i.e., 10,000 ppm) or greater are required to be listed on a product SDS (unless the ingredient poses an extreme health hazard.) . .

  14. Waste Management Review Question 10: Find 2 errors in this waste storage situation

  15. Waste Management Review Find 2 errors in this waste storage situation This chemical is not labeled and that is one of the problems with this situation. Labeling chemicals as Hazardous Waste is a relevant procedure. • In this situation the container lid is not being used. Make sure you use the appropriate lid and close chemical waste containers tightly. Actually this is the correct procedure to follow. You should always use a secondary container in SAA situations

  16. Waste Management Review • Waste must be compatible with the container it is stored in. TRUE FALSE • Waste containers must be closed all the time except when placing waste into the container. TRUE FALSE • Never accumulate more than 1 quart (946 milliliters) of P-listed waste. TRUE FALSE • At UCCS, you should not accumulate more than 10 gallons (37 liters) of U-listed or characteristic waste. TRUE FALSE • Your chemical waste containers must be inspected weekly. TRUE FALSE

  17. Waste Management Review - answers • Waste must be compatible with the container it is stored in. • Waste containers must be closed all the time except when placing waste into the container • Never accumulate more than 1 quart (946 milliliters) of P-listed waste. • At UCCS, you should not accumulate more than 10 gallons (37 liters) of U-listed or characteristic waste. • Your chemical waste containers must be inspected weekly. All statements are true. You should not accumulate more than 1.0 quart of P-listed wastes in the SAA.

  18. Waste Management Review • Chemical waste containers can be left unattended if tightly sealed and properly labeled. TRUE FALSE False. Chemical waste containers must always be under your control. The waste container must be under visual observation at all times. If no one is present, waste must be under lock and key

  19. Waste Management Question 17: How do you dispose of an outdated laptop computer? Review Contact the Environmental Health and Safety Department Dispose into trash compactor by janitor. Recycle through a "commercial recycler." Contact UCD Space and Asset Management. You should contact UCD Space and Asset Management. . .

  20. Waste Management Question 18 : If you are working with a chemical that is found on the F, P or U list, what does this imply? Review The chemical is never a regulated waste. The chemical can be sink disposed. Any chemical found on these lists should be disposed as regulated waste through EHS. Only unused chemical is a regulated waste. Any chemicals found on the F, P or U list should be disposed of as regulated waste. . .

  21. Waste Management You should now be prepared to take the quiz found on the EHS website. http://www.uccs.edu/Documents/pusafety/EHS/Training/Lab%20Safety%20Quiz.doc Review
