9. Safety is a Choice • Safety depends on choices • Good choices rely on having good information before the choice has to be made.

10. How Do We Get That Information? • Training • Initial • Periodic • As-needed • Resources • MSDS/SDS, Labels, Chemical Hygiene Plan (CHP), Emergency Response Plan, Faculty Advisor, Person In Charge (PIC), Lab Placards • Ask Questions!

11. What Questions Should I ask? • What is the nature of my lab? • My work space • My neighbor’s work space • What hazards are present? • Chemical/Physical/Bio/Rad • Do you know how to react? • Have you practiced? • Have you shared your knowledge? • Is there an Emergency Plan, Chemical Hygiene Plan, SDS?

12. Emergency Response Plan, Share, Practice

13. In Your Research Group • Make a plan • Write it down • Ensure everyone understands • Review and practice

14. Emergency Response Plan • Identify local emergency numbers • Locate medical treatment centers and trauma centers • Procedures for dealing with an emergency • Physical injury • Chemical exposure • Environmental Exposure • Evacuation and Meetinglocation

15. Types of Emergencies • Accidents • Spills / Splashes / Accidental Releases • Near Misses • Fire • UT Alert System (http://www.utk.edu/utalert/)

16. Who You Gonna Call? • Emergencies – 911 • Chemical spill or release – EHS – 4-5084 (do not leave a voicemail message) • After hours spill or release – UTPD – 4-3111

17. Physical Hazards Plan, Share, Practice

18. What are Physical Hazards • Environmental Hazards • Work area conditions • Hot/cold, humid/dry, improper lighting • Chemically Produced Physical Hazards • Explosives & Reactives • Equipment Hazards • Mechanical, Electrical, Vacuum, High pressure, Cut and Abrasion Hazards, Hot and Cold equipment, Open flames, Noise/Sound

19. Environmental hazards • Number one type of accident is still “Slips, Trips, and Falls” • Maintain safe pathways and use good housekeeping • Keep cables and cords in safe paths where they will not be damaged and they will not contribute to trip hazards.

20. Chemically Produced Physical Hazards • Highly Reactive compounds and incompatibles can cause very powerful energy release in the form of intense light, heat or pressure waves.

21. Chemically Produced Physical Hazards • Use only the scale of reaction required and approved to achieve your goals. • Use proper PPE and Engineering Controls to prevent exposure to a potential explosion • If the agent/reaction has the possibility of a violent reaction believethat it could happen to you.

22. Equipment Hazards • Mechanical • Electrical • Vacuum/High pressure • Cut and Abrasion Hazards • Hot and Cold equipment • Open flames • Noise/Sound

23. Mechanical Hazards • Know and train on even the most basic equipment. • Equipment with moving parts can entrap extremities, clothing, and long hair. • Use proper clothing and PPE and tie back long hair. • Ensure guards are in place and in good condition. • Never remove safety devices • Moving objects can throw objects • Use lockout tagout procedures when repairing

24. Electrical Hazards • Ways to avoid common lab electrical hazards are ensuring cables and cords are not damaged by the lab environment. • Avoid heat/flame damage to insulation • mechanical trauma such as the damage a cord may receive behind a heavy object such as a gas cylinder.

25. Electrical Hazards cont’d • Do not daisy chain extension cords or power strips. • Extension cords are designed for temporary use only. • If electrical work is needed in your lab a qualified electrical worker is required to do the work. • Use GFCI outlets when the risk of shock is higher such as at sinks and water sources. • Note: Grounding and GFCI are not the same.

26. Electrical Hazards cont’d • Never bypass a grounding prong on an electrical plug. • If your outlets are not “holding” or “gripping” the plug, then notify facilities services as the outlet may be damaged and a fire hazard. • If work is required in your lab please ensure you are aware of what a lockout condition is and how it relates to you as a non-electrical worker.

27. Vacuum and High Pressure • Chance of Implosion or Explosion • Particularly dangerous with Glassware • For pressurized equipment and glassware: • Ensure a blast shield or hood sash is in place. • If using a face shield eye protection must be worn as well

28. THINK Safety… • Broken Glassware should be replaced. • Use proper technique and PPE when working. • Good housekeeping keeps Glassware from: • Accumulating in the dirty bin • Accidentally being knocked over • Don’t forget that when you need to move something large or cumbersome around the lab a pair of sturdy work gloves may be in order.

29. Hot and Cold Equipment • Most lab surfaces that are heated look the same hot and cold: “Hot Glass Looks Like Cold Glass” • Remember to allow proper cooling times on heated elements before work or repair • Use caution with heating mantles and hotplates around combustible and flammable materials

30. Hot and Cold Equipment cont’d • Use Cryo gloves and eye protection when working with Liquid Nitrogen or dry ice. • Flash Freezing works well on samples • It also can work well on you • Dispense and Transport Liquid Nitrogen only with approved methods.

31. Open Flames • Never leave unattended. • Keep away from flammable and combustible materials including volatile flammable gases • Keep hair tied back and loose clothing away

32. Noise and Sound • Hearing protection programs can be required under OSHA. • Thresholds are set for an 8-hour work day • EHS can survey a work area on request.

33. Chemical Hazards Hazard Classes Storage Use & Handling

34. Hazard Classes • Oxidizer • Flammable • Explosive • Acutely Toxic • Corrosive • Compressed Gases • Health Hazard • Environmental Toxin • Exclamation Mark

35. How do you know? • Lab Door Placard • SDS • Chemical labels • Chemical Hygiene Plan • SOPs • Hazardous Communication (Right-To-Know)

36. Incompatible Chemicals • Oxidizers and flammables • Acids and bases • Flammables and corrosives • Corrosives and metals • Know what to do with strong reactions

37. Segregation and Storage • Segregate incompatibles by storing in different cabinets • Use secondary containment when space is at a premium

38. Do • Segregate by hazard class first • Use proper containers • Use secondary containment • Check expiration dates • Inspect shelving and shelf clips periodically • Don’t • Stack chemicals or store too high • Allow containers to hang over edge • Use food containers • Allow excessive bench top and fume hood storage • Keep chemicals indefinitely or past expiration dates • Store flammables in unapproved refrigerators

39. Some chemicals are unstable when stored past their expiration dates: Ethyl ether (diethyl ether) Sodium Azide Picric Acid

40. Chemical Use and Handling • Lab Specific SOPs • Chemical Hygiene Plan • Chemical Inventory

41. How to Reduce the Risk of Exposure • Know the hazards • Use Proper PPE • Routes of exposure • Contact • Injection • Inhalation • Ingestion

42. Engineering Controls • Fume Hoods • Shields • Storage Cabinets • Secondary Containment ex. Spill Trays

43. Transporting Chemicals • Use a cart with secondary containment • Move limited quantities • Use caution going through doorways and public areas • Use freight elevator

44. Shipping Chemicals • Best practice – order from manufacturer • Must be authorized to ship haz mat • Must give minimum of 72 hours notice

45. Labeling • Deface old labels when reusing containers • Label containers clearly (contents, your name, date)

46. Handling Chemicals Safely • Do not eat or drink in the chemical laboratory. • Provide break area outside the lab

47. Personal Protective Equipment Clothing Eye Protection Hand Protection

48. Proper Clothing • Long pants • Long sleeves • Closed-toe, non-absorbent shoes • Protect your clothing with a lab coat or apron

49. Eye Protection • The type of eye protection required depends on the work being performed. • Wearing the proper eye protection is required by the Laboratory Standard and Personal Protective Equipment Standards.

50. Eye Protection • It is the responsibility of the employer to determine the presence of hazards, select and purchase the appropriate safety devices, and train the employees. • The employer is not required to provide prescription safety eyewear.
