OSHA’s Respiratory OSHA’s Respiratory Protection Standard Protection Standard

29 CFR 1910.13429 CFR 1910.134

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

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 than 9/8/98 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

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

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

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

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

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

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

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

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:

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

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

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

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

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

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

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

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

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

Identification

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

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

To ensure effective implementation Must regularly consult employees to assess

Recordkeeping

Medical evaluations retained per 29 CFR 1910.1020

Fit test records until next fit test Written program
