Presentation Transcript

  1. Laboratory Standard

  2. Laboratory use of hazardous chemicals • Chemical manipulations are carried out on a laboratory scale • Multiple chemical procedures or chemicals are used 1a

  3. Laboratory use of hazardous chemicals • Procedures are not part of, and do not simulate a production process • Protective laboratory practices and equipment are available to minimize employee exposure 1b

  4. Permissible exposure limits cannot be exceeded • PEL is the level a person can be regularly exposed to without adverse effects • Eight-hour time-weighted average • Ceiling concentration limits • Skin designation limits 2a

  5. Permissible exposure limits cannot be exceeded • Action level is an exposure level OSHA has designated for a specific substance • Eight-hour time-weighted average • Exposures at action level initiate exposure monitoring, medical surveillance 2b

  6. Exposure monitoring • Measured when there is reason to believe exposure levels exceed action level or PEL • Performed for substances regulated by an OSHA standard that requires monitoring 3a

  7. Exposure monitoring • Monitoring may be terminated in accordance with regulation • Employees must be notified of monitoring results within 15 working days • Individually • Posting results in accessible location 3b

  8. Chemical Hygiene Plan - Basic operating procedures • What to do for accidents and spills • How to avoid routine exposures • How to choose chemicals 4a

  9. Chemical Hygiene Plan - Basic operating procedures • Where to eat, drink, chew gum, smoke, apply cosmetics 4b

  10. Chemical Hygiene Plan - Basic operating procedures • How to properly use glassware and equipment • Hygiene practices upon leaving laboratory 4c

  11. Chemical Hygiene Plan - Basic operating procedures • Proper behavior in laboratory - no horseplay • How to pipette - no mouth suction • Appropriate personal apparel and PPE 4d

  12. Chemical Hygiene Plan - Basic operating procedures • Be aware of unsafe conditions - plan ahead, follow warnings, work under exhaust hoods • Properly dispose of wastes • Do not work alone when performing hazardous procedures 4e

  13. Chemical Hygiene Plan • Potential laboratory hazards • Allergens and Embryotoxins • Moderate chronic and high acute toxicity • High chronic toxicity • Animal work with chemicals of high chronic toxicity 4f

  14. Chemical Hygiene Plan • Controls to reduce employee exposure • Engineering controls • Work practice controls • Hygiene practices • PPE 4g

  15. Chemical Hygiene Plan • Ensure that fume hoods function properly • Employer approval is needed before conducting some operations, procedures, activities 4h

  16. Chemical Hygiene Plan • Medical examinations and consultation 4i

  17. Chemical Hygiene Plan • Personnel responsible for implementation of hygiene plan • Chemical hygiene officer • Chemical hygiene committee 4j

  18. Chemical Hygiene Plan • Provisions for employee protection from: • Select carcinogens • Reproductive toxins • Substances with high degree of toxicity 4k

  19. Chemical Hygiene Plan • Provide information about: • Designated areas • Containment devices • Safe removal of contaminated waste • Decontamination procedures • Review plan annually 4l

  20. Training • Location and availability of MSDSs • Training is required upon initial assignment, and prior to new exposure situations 5a

  21. Signs and symptoms of exposure • Each chemical has an MSDS • Read MSDS to determine signs and symptoms of exposure 6a

  22. Methods of detection of a release • Monitoring is conducted • Continuous monitoring devices • Visual appearances • Odor of hazardous chemicals 7a

  23. Medical consultations/examinations • Reasons for medical attention • Care provided by physician without loss of pay • Care provided at reasonable time and place 8a

  24. Medical consultations/examinations • Information provided to physician • Chemicals to which employee is exposed • Exposure conditions • Signs and symptoms of exposure 8b

  25. Medical consultations/examinations • Physician’s written opinion • Confidentiality of information not related to exposure 8c

  26. Labels • Labels on incoming containers cannot be removed or defaced 9a

  27. Respirators - meet 1910.134 requirements • Selection procedures • Proper fit • Proper use and care • Limitations of respiratory protection 10a

  28. Recordkeeping • Records retained for duration of employment plus 30 years • Includes tests and written opinions 11a

  29. Summary of main points • Basic operating procedures • PPE • Hazards of chemicals used • Signs and symptoms of overexposure 12a

  30. Summary of main points • Detection methods of a release, or presence of chemicals • Permissible exposure limits • Required monitoring 12b

  31. Summary of main points • Medical examination requirements • MSDSs and labels • Respirator use • Recordkeeping requirements 12c
