AGENDA

• Types of Respiratory Protection• Definitions• Respirator Selection Process• Examples of Acceptable Respiratory

Protection

Respiratory Protection

• Air Purifying Respirator– Negative Pressure Respirator

Page 4: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Respiratory Protection

• Air Purifying Respirator– Powered Air Purifying Respirator (PAPR)

Page 5: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Respiratory Protection

• Atmosphere Supplying Respirator

Page 6: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Respiratory Protection

• Self-Contained Breathing Apparatus (SCBA)

Page 7: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Definitions

• Assigned Protection Factor (APF)– the workplace level of respiratory

protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program.

Page 8: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Definitions

• Maximum Use Concentration (MUC)– the maximum atmospheric concentration

of a hazardous substance from which an employee can be expected to be protected when wearing a respirator, and is determined by the APF of the respirator and the exposure limit of the hazardous substance. (APF X OEL)

OEL = Occupational

Exposure Limit

Page 9: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Definitions

• Immediately Dangerous to Life or Health (IDLH)– an atmosphere that poses an immediate

threat to life, would cause irreversible adverse health effects, or would impair an individual's ability to escape from a dangerous atmosphere.

Page 10: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Respiratory Protection Program

• Per 29 CFR 1910.134 Written Respiratory Protection Program must include…– Procedures for selecting respirators– Medical evaluation– Fit testing– Use of respirators– Maintenance and care of respirators– Breathing air quality and use– Training– Program evaluation– Recordkeeping

Page 11: Respirator Selection based on OSHA APFs Scott Shinn, CIH, Technical Service Specialist, 3M Company.

Respirator Selection Process

• Exposure Assessment– Typically determined through air monitoring

• Determine APF Required– Concentration in Air ÷ OEL (C/OEL)

• APF Table• Other Considerations
