major changes
Major Changes
  • Different categories of particulate filters
  • End of service life schedule
  • Designate a program administrator
  • New IDLH requirements
  • Voluntary use requirements
  • Medical, training, fit testing details
scope and dates
Scope and Dates
  • This standard applies to general industry, shipyards, marine terminals, longshoring, and construction
  • The effective date is 4/8/98
  • Determination that respirator use is required (paragraph a) to be completed no later than9/8/98
  • Compliance with all other provisions of this standard must be completed no later than 10/5/98
  • Employers may use the results of training, fit testing, medical evaluation conducted within 12 months prior to 4/8/98 if they meet the standard requirements
other osha specific standards
Other OSHA Specific Standards
  • Respirator related provisions of OSHA’s existing standards are revised to conform to the revised 1910.134
  • All provisions addressing respirator use, selection, and fit testing are deleted from OSHA’s specific substance standards

  • B-2 Cleaning procedures
  • C Medical questionnaire
  • D Information for employees wearing respirators when not required
permissible practice
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)
respirator program
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
voluntary use
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
program elements
Program Elements
  • Selection
  • Medical evaluation
  • Fit testing
  • Use
  • Maintenance and care
  • Breathing air quality
  • Training
  • Program evaluation
selection of respirators
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 employee’s exposure
  • If estimate cannot be performed consider atmosphere IDLH
  • Select from sufficient number of models and sizes
respirators for idlh
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
respirators for atmospheres not idlh
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
for protection against particulates provide
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
niosh requirements 42 cfr part 84
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
classes of filters
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)
selection of n r or p
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
selection of filter efficiency
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 100/2+5 = 14.2
  • N95 with half mask suitable for many conditions with hazard grade below 6.
medical evaluation
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
fit testing
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
use of respirators
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
maintenance and care
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
  • All filters, cartridges, and canisters must be labeled and color coded with the NIOSH approval label
training and information
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
program evaluation
Program Evaluation
  • To ensure effective implementation
  • Must regularly consult employees to assess
  • Medical evaluations retained per 29 CFR 1910.1020
  • Fit test records until next fit test
  • Written program
