Regulatory Requirements

• 29 CFR 1910.134
• Covers all required and voluntary use of
  respiratory protection in general industry
• Requires a written program

  and fit-testing
• Standard revised in 1998

3
Types of Respiratory Protection

• Atmosphere supplying
• Self-contained breathing apparatus (SCBA)
• Airline respirators
• Air purifying
• Gas and vapor
• Particulate
• Combination

4
Types of Face Pieces

• Mouthpiece
• Single use/disposable
• Quartermask
• Half mask
• Full face
• Helmet

5
Effective Use of Respirators

• During installation ofengineering controls
• During maintenance operations
• During process turnarounds
• For nonroutine tasks
• For emergency response
• At hazardous waste site operations
• When other controls are inadequate
• When other controls are not feasible

6
Employee Effectiveness

• The use of respiratory protection limits the
  effectiveness of the employee by 33.33 percent.

7
Maximum Use Concentrations

• Half mask w/ov cartridge 1,000 ppm or 10x the
  PEL, whichever is lower
• Full face w/ov cartridge 1,000 ppm or 50x the
  PEL, whichever is lower
• Full face w/acid gas chin canister 2 by volume
  or 50 times the PEL, whichever is lower
• Note In general, never exceed an APF.

8
Respirator Selection Criteria

• Physical state of the contaminant
• Contaminant concentration
• Oxygen deficiency
• Warning properties of contaminant
• Potential for IDLH atmospheres
• Can contaminant be ad/absorbed by a media?
• Can contaminant be ad/absorbed by the skin?
• Is the contaminant irritating to the eyes?

9
Types of Fit-testing

• Qualitative
• Isoamyl acetate
• Irritant smoke
• Quantitative
• DOP/corn oil
• Ambient atmosphere (portacount)

10
Elements of a Respiratory Protection Program

• Written operating procedures
• Proper selection
• Training and fitting
• Cleaning and disinfecting
• Storage
• Inspection and maintenance
• Work area surveillance

11
Respiratory Program (cont.)

• Inspection and evaluation to determine
  effectiveness
• Medical examinations

12
Revision to 1910.134

• Effective date April 8, 1998
• Enforcement date October 5, 1998

13
Written Program Requirements

• Must be site-specific
• Must have a program administrator
• Must be developed when respirator use is required

14
When Respirators Are Not Required

• Can use employee respirator if it does not
  create a hazard
• Voluntary users of respirators must be given
  Appendix D
• Appendix D employee information when
  respirators are not required
• Employers must implement a program for
  nonrequired users

15
Respirators Not Required (cont.)

• If dust masks only are used and not required, no
  written program is required
• Appendix D of the standard must be provided to
  users

16
General Requirements

• Use of NIOSH-approved respirators only
• Evaluation of hazards
• Availability of multiple respirator types

17
Respirators for Non-IDLH Use

• If cartridges have no end of service life
  indicator a change schedule must be used
• Added table for oxygen-deficient atmospheres
  based on altitude

18
Medical Evaluation

• Use of medical questionnaire (Appendix C)
• Follow-up medical exam for any positive response
  to questionnaire
• All medical evaluations must be made
  confidentially
• Employees must be allowed to discuss the
  questionnaire with the physician

19
Medical Evaluation (cont.)

• Physicians must be told conditions of respirator
  use
• Employers must provide a PAPR if employees
  cannot use a negative pressure APR
• Follow-up evaluations must be conducted if
  conditions of use or user health change

20
Fit-Testing

• Respirators will not protect you if they dont
  fit properly!
• Required for negative or positive pressure
  tight-fitting face pieces
• Must be conducted prior to use
• Must be conducted at least annually
• Must be retested if respirator fit or wearer
  changes

21
