Permissible Practice

• Primary means of control of breathing
  contaminated air is through use of feasible
  engineering controls
• If not feasible or while implementing respirators
  shall be used
• Respirators must be appropriate for use intended
• Employer is responsible for establishment of
  respirator program as discussed in paragraph (c)

7
Respirator Program

• Develop a written program with worksite specific
  procedures
• Update program as needed as conditions change
• Designate a program administrator who is
  qualified
• Provide respirators, training, and medical
  evaluations at no cost to employees

8
Voluntary Use

• If voluntary use of dust masks is permissible,
  employer must provide appendix D information
• For other respirator use, must implement medical
  evaluation and cleaning, storage, and maintenance
  requirements

9
Program Elements

• Selection
• Medical evaluation
• Fit testing
• Use
• Maintenance and care
• Breathing air quality
• Training
• Program evaluation

10
Selection of respirators

• Employer must select appropriate respirator based
  on respiratory hazards and user factors which
  affect performance and reliability
• Select NIOSH certified respirators and use in
  compliance with conditions of certification
• Identify and evaluate the respiratory hazards in
  the workplace and estimate the employees
  exposure
• If estimate cannot be performed consider
  atmosphere IDLH
• Select from sufficient number of models and sizes

11
Respirators for IDLH

• Use full facepiece pressure demand SCBA certified
  by NIOSH for minimum life of 30 minutes, or
• Combination full facepiece pressure demand with
  auxiliary self contained breathing supply
• All oxygen-deficient atmospheres are considered
  IDLH

12
Respirators for atmospheres not IDLH

• Provide an atmosphere supplying respirator, or
• Provide an air purifying respirator, provided
  that
• Equipped with and end of service life indicator,
  or
• Implement a change schedule based on objective
  information, and must describe the information
  and data relied upon for the schedule

13
For protection against particulates, provide

• An atmosphere supplying respirator, or
• An air-purifying respirator with HEPA filter
  under NIOSH CFR Part 11 or with filters certified
  for particulates under 42 CFR Part 84

14
NIOSH Requirements 42 CFR Part 84

• On July 10, 1995, 30 CFR 11 was replaced by 42
  CFR 84
• Only certifications for nonpowered, air
  purifying, particulate respirators are affected
• Remaining portions of Part 11 incorporated into
  Part 84 without change
• Permits manufacture and sale of Part 11
  respirators until July 10, 1998
• Distributors and end users may deplete supplies
  until inventories are exhausted

15
Classes of Filters

• Old Part 11 used dust, fume, mist classification
• Part 84 has 3 classes based on characteristics
  against oil containing hazards, and 3 classes
  based on filtering efficiency
• Levels of efficiency are 95, 99, and 99.97
• Oil resistance categories are N (not resistant),
  R (resistant), and P (oil proof)
• Filters are clearly marked (i.e. N95)

16
Selection of N, R, or P

• If no oil present, use either N, P, or R
• If oil particles are present, use only R or P
• If oil present and respirator used for more than
  1 shift, use only P

17
Selection of filter efficiency

• Must consider overall respirator performance
  needed
• Calculate hazard grade ( exposure/limit)
• Must know protection factor of respirator
• Example
• Half mask with HEPA - protection factor is 10
• Half mask with N95 - protection factor is 100/10
  5 6.6
• Full face with N 95 - protection factor is
  100/25 14.2
• N95 with half mask suitable for many conditions
  with hazard grade below 6.

18
Medical Evaluation

• Must be done before fit testing and use to
  determine users ability to wear respirator
• Identify a PLHCP (physician or other licensed
  health care provider) to perform evaluations
  using the questionnaire or other examination
  which obtains information
• Appendix C Part A questionnaire
• Follow up exam required if positive response to
  any question of questions 1-8 in section 2
• Annual review required

19
Fit Testing

• Before employee uses tight fitting facepiece
• Must pass QLFT or QNFT
• At least annually, or other changes in physical
  condition of employee
• QLFT OK if fit factor of 100 or less is needed

20
Use of respirators

• Cannot use tight fitting respirators if facial
  hair or other conditions which may interfere with
  seal
• Glasses or goggles must not interfere with seal
• Users must perform a user seal check each time
  put on per procedures in Appendix B-1
• Maintain appropriate surveillance of work area
  conditions and degree of exposure
• IDLH
• Locate one employee outside the IDLH area
• Maintain voice or other communication
• Outside employee must be trained and equipped for
  emergency rescue

21
Maintenance and care

• Provide respirator that is clean, sanitary, and
  in good working order
• Use procedures in Appendix B-2
• Clean and disinfect
• as often as needed when used for exclusive use
• before being worn by different employee
• after each use for emergency respirators

22
Identification

• All filters, cartridges, and canisters must be
  labeled and color coded with the NIOSH approval
  label

23
Training and information

• Employees must demonstrate knowledge of
• why respirator is needed
• use in emergency situations
• how to inspect, put on, and check seals
• how to store
• medical signs and symptoms which may limit
  effective use
• general requirements of the standard
• how to fit test and maintain
• Train prior to use and annually, or when changes
  occur
• Provide Appendix D to all users

24
Program Evaluation

• To ensure effective implementation
• Must regularly consult employees to assess

25
Recordkeeping

• Medical evaluations retained per 29 CFR 1910.1020
• Fit test records until next fit test
