Presentation Transcript

  1. Inorganic Arsenic

  2. Contents of the regulation • Regulation is limited to: • copper aceto-arsenite and • all inorganic compounds containing arsenic except arsine • A copy of the regulation is available to employees • Regulated areas 1a

  3. Contents of the regulation • Post signs 1b

  4. Contents of the regulation • Only authorized persons may enter regulated areas • List job titles/functions of those allowed to access regulated areas 1c

  5. Contents of the regulation • Make monitoring program clear to employees • Company has obligation to control exposures • Permissible exposure limits • Engineering and work practice controls 1d

  6. Contents of the regulation • Inform employees: • at least quarterly for employees who have optional use of respirators • at least annually of the information in the regulation 1e

  7. Contents of the regulation • Training must include: • proper work practices • emergency procedures • proper use of PPE • Employees must be able to observe air monitoring 1f

  8. Contents of the regulation • Air monitoring depends upon the following factors: • Above the action level but below the PEL - at least every 6 months • Changes in personnel, processes, controls 1g

  9. Contents of the regulation • Companies must develop and implement a written compliance plan 1h

  10. Material safety data sheets (MSDSs) • Hazard communication program • Where to get copies of MSDSs • 29 CFR 1910.1200 2a

  11. Material safety data sheets (MSDSs) • Labeling requirements 2b

  12. Material safety data sheets (MSDSs) • Keep labels useable, legible 2c

  13. Health hazards • Immediate (acute) effects • Skin contact - corrosive, irritation • Ingestion - pain, vomiting, diarrhea • Inhalation - cough, chest pain, weakness 3a

  14. Health hazards • Long-term (chronic) effects • Inhalation - chronic poisoning • First phase • Second phase • Third phase • Carcinogenic • Liver damage is still debated • Affects bone marrow 3b

  15. Engineering controls • Primary methods of exposure control • Review controls and practices 4a

  16. Emergency procedures • Everyone must understand his/her duties/assignments • Know how to report emergencies 5a

  17. Emergency procedures • Know how to evacuate safely • Know facility emergency plan • Respond within scope of training 5b

  18. Medical surveillance • Required for all employees: • exposed above the action level for 30+ days/year • exposed during an emergency • showing signs/symptoms of exposure 6a

  19. Medical surveillance • Exposure thresholds are determined without respirator use 6b

  20. Medical surveillance • Examinations will be: • prior to assignment • at least annually for employees under 45 years old with fewer than 10 years of exposure over the action level 6c

  21. Medical surveillance • Examinations will be: • at least semi-annually for other employees • whenever an employee shows signs/symptoms of toxic levels of exposure 6d

  22. Medical surveillance • Examination includes: • work and medical history • posterior/anterior chest x-ray • nasal and skin examination • sputum cytology exam • any other tests deemed necessary 6e

  23. Medical surveillance • Physician gives written opinion, including: • all test results • the physician’s opinion about employee’s medical condition • recommended limitations 6f

  24. Medical surveillance • Physician gives written opinion, including: • a statement that the employee has been informed of results • if there is a need for further treatment 6g

  25. Medical surveillance • Records are required to be retained by the employer: • X-rays for the most recent five years • Cytologic exam slide and written descriptions for the most recent five years 6h

  26. Medical surveillance • Records are required to be retained by the employer: • Cytologic exam slide with demonstrated atypia if atypia persists for three years 6i

  27. Medical surveillance • Records are required to be retained by the employer: • overall retention is for 40 years; or • the employee’s term of employment plus 20 years, whichever is longer • Employees have the right to access records 6j

  28. Personal protective equipment • Impermeable clothing • Gloves • Goggles • Face shields 7a

  29. Personal protective equipment • Other protective gear • Selection, use, inspection, limitations, cleaning and disposal 7b

  30. Personal protective equipment • Changing rooms • Lunch rooms • Removing/storing contaminated clothing 7c

  31. Personal protective equipment • Exposed workers must: • wash face and hands before eating, drinking, smoking, applying cosmetics • take showers at the end of the shift 7d

  32. Personal protective equipment • Don’t take contaminated clothing home • Blowing or shaking clothes to remove arsenic is prohibited 7e

  33. Personal protective equipment • Respirators are required: • during the period necessary to install or implement engineering/work practice controls • in operations where engineering/work practice controls are not feasible 7f

  34. Personal protective equipment • Respirators are required: • in work operations where engineering/work practice controls do not reduce exposure below the PEL • in emergencies 7g

  35. Personal protective equipment • Workers have an affirmative duty to wear respirators • Periodic respirator fit tests are required 7h
