Respiratory Protection Hazmat Industry Technician
Respiratory Protection Regulation • Intent of regulation • Protect workers from respiratory hazards • Insufficient oxygen • Harmful dust, gases and vapors
Requirements of Regulation • Employer must use • Engineering controls • Respirators • Employer must have written program
Emergency Response • Employees mustuse SCBA
Types of Respirators • Air-Purifying respirator (APR) • Powered APR (PAPR) • Self-contained breathing apparatus (SCBA) • Supplied-air respirator (SAR)
Types of Atmospheres • IDLH – immediately dangerous • Oxygen deficient – less than 19.5%
Fit Tests • Qualitative • Uses a test agent • Quantitative • Measures air leakage
Respiratory Protection Program • Must have written plan • Must have suitably trained administrator
Program Must Include… • Procedures for selecting respirators • Medical evaluations • Fit testing procedures • Procedures for use
Program Must Include… • Procedures for cleaning & storing • Procedures to ensure adequate air • Training of employees • Procedures to evaluation effectiveness • When respirators aren’t required
Respiratory Protection Equipment • SCBA • SAR • APR • PAPR
SCBA • Highest level of respiratory protection • Required in emergency response
Cylinder SCBA Components Regulator Facepiece Harness
SAR • Provides larger air supply • Work duration is longer • Weighs less than SCBA • Hose length is limited (300 feet) • Requires emergency escape cylinder
APR • Removes contaminants • But not all! • Must know what contaminants are present • Cartridges are specific to the hazard
PAPR • Has battery powered blower • Easier to breathe
APR/PAPR Advantages • Lighter weight • Provides more mobility
APR/PAPR Disadvantages • Doesn’t provide oxygen • Filters can clog • Cartridges are specific to the hazard
Entering IDLH Atmospheres • ID potential IDLH conditions prior to entry!
IDLH Atmosphere • Oxygen deficient • Concentration above NIOSH IDLH level
IDLH Atmosphere • Inhalation or skin absorptive hazards • Confined spaces • Explosive/flammable conditions • Visible vapor clouds
Entering IDLH Atmosphere • Must have backups • 2 in, 2 out
Respirator Use and Storage • Goal • Maintain face piece seal • Ensure respirator is effective
Maintaining Seal • Remove physical barriers to seal • Facial hair, jewelry, glasses, etc. • Perform seal check • Not a substitute for fit test!
Inspecting Respirators • Check at least monthly • Check for: • Respirator function (all parts) • Pliability • Signs of deterioration
Employer Requirements • Certify respirators • Tag or label all respirators • Provide details of how to store respirators
Medical Considerations • Using respirator is a physical burden • Medical evaluation is required
Medical Exams • Initial and follow-up • Done at employer’s expense • Done during normal work hours • Results are confidential
Details of Your Plan • Instructor will cover this
