Presentation Transcript

  1. Cadmium

  2. Regulated areas • Regulated areas are created where employees are exposed to concentrations above the PEL • Respirators are provided for employees who must access regulated areas 1a

  3. Regulated areas • You must wear respirators when required to do so • What job titles/functions are allowed access to restricted areas • Tour of regulated areas 1b

  4. Requirements • Substance safety data sheet (Appendix A) • Substance technical guidelines for cadmium (Appendix B) 2a

  5. Requirements • Employers are required to control exposures to cadmium • Airborne concentrations must not exceed the action level or PEL 2b

  6. Monitoring • Methods of detecting the presence or release of cadmium • Monitoring must be made available for employees to observe 3a

  7. Monitoring • If monitoring shows exposure at or above the action level, monitoring must be done: • at least every six months • when there are changes to personnel, processes, or controls • Lunchrooms are monitored and kept below the action level 3b

  8. Monitoring • Employees have a right to be notified in writing of monitoring results within 15 working days • Written notification must include corrective actions 3c

  9. Physical hazards • Flammable and explosive in powder form • Spontaneous combustion of dust 4b

  10. Physical hazards • Sensitive to reaction with: • oxidizers • metals • hydrogen nitrite • zinc • selenium • sulfur dioxide • tellerium 4c

  11. Physical hazards • Fire hazard when exposed to these chemical/substances: • oxidizers • metals • hydrogen nitrite • zinc • selenium • sulfur dioxide • tellerium 4d

  12. Physical hazards • Fight fire with: • dry sand • dry dolomite • dry graphite • sodium chloride • Do not use water, foam, carbon dioxide or Halons 4e

  13. Acute health hazards • Skin irritation • Eye irritation • Inhalation 4f

  14. Acute health hazards • Ingestion • Observable effects 4g

  15. Chronic health hazards • Carcinogen • Kidney damage • Respiratory damage 4h

  16. Chronic health hazards • Reproductive health changes • Mutagenic • Tumorigenic 4i

  17. Work practices • Engineering controls and work practices are primary methods of control • Do not shake, blow, or use any other means to clean clothing, that would cause cadmium to become airborne 5a

  18. Work practices • Rotation of work duties is not a valid method of compliance • Keep work surfaces free of cadmium • Clean up spills 5b

  19. Work practices • Use HEPA-filtered vacuuming methods • Compressed air for cleaning should be used only with proper ventilation 5c

  20. Work practices • Be aware of washing facilities • Respirators must be used where required 5d

  21. Emergency procedures • Written emergency action plan • First aid measures • Eyes • Skin • Inhalation • Ingestion 6a

  22. Emergency procedures • Emergency evacuation 6b

  23. Emergency procedures • Cadmium metal dust is a fire hazard and reacts with: • oxidizers • acids • ammonia • selenium • sulpher dioxide 6c

  24. Personal protective equipment • Required for employees exposed above the PEL; or where skin or eye irritation is associated with exposure • Coveralls • Gloves, head coverings, and boots • Face shields, vented goggles 7a

  25. Personal protective equipment • Selection, use, limitations, inspection • Cleaning and disposal • Changing rooms and storage 7b

  26. Personal protective equipment • Repair/replace defective equipment • Decontamination • Any employee whose clothing is contaminated must immediately remove clothing and shower 7c

  27. Personal protective equipment • Washing contaminated clothing • Splashproof eye or dust-resistant goggles 7d

  28. Limitations of respirators • Respirators are a critical element of the training program • Employees have a duty to wear respirators • Proper selection, donning, doffing, use, limitations, decontamination and storage 8a

  29. Medical surveillance • Required for all employees who are, or may be exposed at or above the action level • Medical examinations are thorough 9a

  30. Medical surveillance • Employees may be medically removed from duty if testing/monitoring detects ongoing problems 9b

  31. Medical surveillance • Copies of physician’s written opinions • Records are retained for the duration of employment plus 30 years 9c

  32. Medical surveillance • Examinations will be conducted: • within 30 days of assignment • at least annually • whenever an employee is exposed above the action level • following an exposure • whenever an employee shows signs/symptoms of exposure 9d

  33. Medical surveillance • Examinations will be conducted: • for a year after an employee stops working with cadmium • at termination of employment • Examinations may be scheduled if biological monitoring detect high levels of cadmium 9e

  34. Labeling system • Post and maintain signs around regulated areas • Report faded or missing signs 10a

  35. Labeling system • Labels are required on all containers similar to the following: 10b

  36. Copies of the standard • Copies of the standard are available to employees 11a
