  1. Respiratory Protection Hazmat Industry Technician

  2. Respiratory Protection Regulation • Intent of regulation • Protect workers from respiratory hazards • Insufficient oxygen • Harmful dust, gases and vapors

  3. Requirements of Regulation • Employer must use • Engineering controls • Respirators • Employer must have written program

  4. Emergency Response • Employees mustuse SCBA

  5. Types of Respirators • Air-Purifying respirator (APR) • Powered APR (PAPR) • Self-contained breathing apparatus (SCBA) • Supplied-air respirator (SAR)

  6. Types of Atmospheres • IDLH – immediately dangerous • Oxygen deficient – less than 19.5%

  7. Fit Tests • Qualitative • Uses a test agent • Quantitative • Measures air leakage

  8. Respiratory Protection Program • Must have written plan • Must have suitably trained administrator

  9. Program Must Include… • Procedures for selecting respirators • Medical evaluations • Fit testing procedures • Procedures for use

  10. Program Must Include… • Procedures for cleaning & storing • Procedures to ensure adequate air • Training of employees • Procedures to evaluation effectiveness • When respirators aren’t required

  11. Respiratory Protection Equipment • SCBA • SAR • APR • PAPR

  12. SCBA • Highest level of respiratory protection • Required in emergency response

  13. Cylinder SCBA Components Regulator Facepiece Harness

  14. SAR • Provides larger air supply • Work duration is longer • Weighs less than SCBA • Hose length is limited (300 feet) • Requires emergency escape cylinder

  15. APR • Removes contaminants • But not all! • Must know what contaminants are present • Cartridges are specific to the hazard

  16. PAPR • Has battery powered blower • Easier to breathe

  17. APR/PAPR Advantages • Lighter weight • Provides more mobility

  18. APR/PAPR Disadvantages • Doesn’t provide oxygen • Filters can clog • Cartridges are specific to the hazard

  19. Entering IDLH Atmospheres • ID potential IDLH conditions prior to entry!

  20. IDLH Atmosphere • Oxygen deficient • Concentration above NIOSH IDLH level

  21. IDLH Atmosphere • Inhalation or skin absorptive hazards • Confined spaces • Explosive/flammable conditions • Visible vapor clouds

  22. Entering IDLH Atmosphere • Must have backups • 2 in, 2 out

  23. Respirator Use and Storage • Goal • Maintain face piece seal • Ensure respirator is effective

  24. Maintaining Seal • Remove physical barriers to seal • Facial hair, jewelry, glasses, etc. • Perform seal check • Not a substitute for fit test!

  25. Inspecting Respirators • Check at least monthly • Check for: • Respirator function (all parts) • Pliability • Signs of deterioration

  26. Employer Requirements • Certify respirators • Tag or label all respirators • Provide details of how to store respirators

  27. Medical Considerations • Using respirator is a physical burden • Medical evaluation is required

  28. Medical Exams • Initial and follow-up • Done at employer’s expense • Done during normal work hours • Results are confidential

  29. Details of Your Plan • Instructor will cover this
