  8. UT Student Health Center 1800 Volunteer Blvd. If Treatment Is Needed UT Medical Center 1924 Alcoa Highway

  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 In Charge, Person In Charge (PIC) • 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. Make a plan • Write it down • Ensure everyone understands • Review and practice

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

  15. 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

  16. Physical Hazards Know your work environment

  17. 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

  18. 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.

  19. 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.

  20. 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.

  21. 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 parts can throw objects • Use lockout tagout procedures when repairing

  22. 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 such as with hotplates or • mechanical trauma such as the damage a cord may receive behind a heavy object such as a gas cylinder.

  23. 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.

  24. 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.

  25. Vacuum and High Pressure • Chance of Implosion or Explosion • Where do all the parts go? • 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

  26. THINK Safety… • Broken Glassware should be replaced. • Good housekeeping keeps your lab both looking better and safer. • PIC’s look around your lab and ask…Do we have the PPD we need?Does the lab look safe?

  27. Hot and Cold Equipment • 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.

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

  29. 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.

  30. Chemical Hazards Hazard Classes Storage Use & Handling

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

  32. How do you know? • SDS • Chemical labels • Chemical Hygiene Plan • SOPs

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

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

  35. 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

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

  37. Have these chemicals been stored too long?

  38. Chemical Use and Handling • Lab Specific SOPs • Chemical Hygiene Plan • Chemical Inventory • Use chemical hoods

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

  40. Labeling • Deface old labels when reusing containers • Label containers clearly • Remove or deface all labels when disposing of containers

  41. Personal Protective Equipment Clothing Eye Protection Hand Protection

  42. Proper Clothing • Long pants • Long sleeves • Closed-toe, non-absorbent shoes • Protect your clothing with a lab coat or apron • What are you taking home on your shoes?

  43. 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.

  44. Eye Protection • Anticipate the presence of hazards, select and use the appropriate safety devices.

  45. What is the first action for chemicals in the eyes? • Immediately begin flushing the eyes with large amounts of tepid water for a minimum of fifteen minutes. • While the eyes are being flushed, medical help should be summoned

  46. Maximum distance from work station to eye wash/safety shower? • It’s not measured by distance, but by time • 10 seconds • For strong caustics/acids equipment should be immediately adjacent to the work area

  47. Additional Eye Safety Precautions • Activate every eyewash at least weekly to verify operation and clear liquid flow • Keep areas around eyewashes clear from clutter to provide quick and easy access in the event of an emergency • Never neutralize chemicals splashed in the eyes – always flush with water only • Never use an emergency eye wash bottle • You must never work alone in the laboratory

  48. So Why Protect My Eyes? You can eat with false teeth, you can dance with a wooden leg, you can even hear with a hearing aid, but you can’t see with a glass eye.
