- Federal Program Change. This instruction describes a Federal Program Change for
which State adoption is not required. However, to ensure that State Compliance Officers
are provided the minimum protection prescribed in 29 CFR 1910.134, each state should
consider adopting similar guidelines.
- Significant Changes. This change incorporates new Respiratory Protection Program
Guidelines developed to conform to the Respiratory Protection Standard, 29 CFR
1910.134. OSHA Regional Administrators and Area Directors will use these guidelines
to establish and implement an OSHA respiratory protection program consistent with the
needs of each Regional and field location.
- Background. Occupational Safety and Health Administration (OSHA) Compliance
Safety and Health Officers (CSHOs) as well as other Agency personnel may be exposed
to a variety of respiratory hazards while conducting safety and health compliance
inspections, consultations or monitoring visits. These hazards include a wide range of
airborne contaminants and in some cases represent immediately dangerous to life or
health (IDLH) conditions.
OSHA considers respirators to be necessary to protect the health of its employees at those
work sites where feasible engineering controls are not available or are not sufficient to
protect employee health, in emergencies, and where the health of a CSHO could be at
risk. Respirators selected must be capable of protecting against overexposure by
reducing and maintaining exposure to or below the relevant exposure limit. In addition to
the OSHA permissible exposure limits (PELs), other relevant exposure limits include:
American Conference of Governmental Industrial Hygienists (ACGIH) recommended
Threshold Limit Values (TLVs), National Institute for Occupational Safety and Health
(NIOSH) Recommended Exposure Limits (RELs), and other occupational exposure
limits. Furthermore, appropriate respirators must be worn whenever requested by the
As a consequence of OSHA's newly promulgated Respiratory Protection Standard, CPL
2-2.54 is now out-of-date. This instruction, CPL 2-2.54A, eliminates the discrepancies
and technical inaccuracies that exist between CPL 2-2.54 and the new standard and
establishes current guidelines to be followed in setting up a respiratory protection
- Respiratory Protection Program.
- Administration of Program.
- Each region must assign a program administrator to oversee the respiratory
protection program for its Area Offices as well as Regional Office
employees requiring respiratory protection. The regional program
administrator is responsible for evaluating the program's effectiveness.
The person selected to perform the responsibilities of this position can be
qualified either by appropriate training or experience or both and will
work under the delegation of the Assistant Regional Administrator for
Technical Support (ARA/TS) and/or Regional Administrator.
- Each Area Office also must have a program administrator to coordinate
the various aspects of the respiratory protection program on a local level.
Although responsibility for respirator program oversight rests with the
Area Director, responsibilities may be delegated to other qualified
individuals such as a supervisor or CSHO with appropriate training and/or
- The responsibilities detailed in Section B, which appear below, are
guidelines for the Regional and Area Offices to follow in setting up a
respirator program. Their implementation and coordination can be
adapted to the offices' specific circumstances. The program
administrator's job is to ensure consistent coordination and direction of the
program as well as to maintain the integrity of the respirator program.

the CSHOs' views on program effectiveness and to identify and
correct any problems. Conduct evaluations of the respiratory
protection program as necessary, and update written programs as
- Maintain records required by the program.
- Have the responsibility to wear respirators when and where
required, and to care for and maintain the respirators in the manner
in which CSHOs are trained. Before going into hazardous areas,
employees should identify those work areas, processes, or tasks
that require respiratory protection.
- Should conduct a pre-inspection evaluation for their potential
exposure to chemicals. They should review all pertinent
information contained in the establishment file and appropriate
reference sources to become knowledgeable about the industrial
processes and potential respiratory hazards that may be
encountered. During the opening conference, a list of hazardous
substances should be developed or obtained, along with any air
monitoring results that the employer has. The CSHO should
determine if he or she has the appropriate respirator to protect
against chemicals present at the work site.
- CSHOs must notify their supervisor or the program administrator:
Program Elements. The respiratory protection program must cover the following
basic elements, as applicable:
- If their respirators no longer fit well, and should request replacements that fit properly;
- If the CSHOs encounter any respiratory hazards during
inspections or onsite visits that they believe have not been previously or
adequately addressed; and
- If they have any other concerns regarding the program.
Selection Procedures. Respirator selection requires correctly matching the
respirator with the hazard, the degree of hazard, and the user. The respirator
selected must be adequate to effectively reduce exposure of the respirator user
under all conditions of use, including reasonably foreseeable emergency escape
situations. Proper respirator selection involves choosing a device that will protect
the CSHO from the respiratory hazards to which he or she may be exposed, yet
permits the CSHO to perform the job with the least amount of physical burden.

air for self-contained breathing apparatus (SCBA);
- Training employees in the respiratory hazards to which they are potentially
- Training employees in the proper use of respirators, including putting on
and removing them, any limitations on their use, and maintenance
- Procedures for regularly evaluating the effectiveness of the program.
Medical Evaluation. CSHOs assigned to tasks that require the use of a respirator
must be physically able to perform the work while using a respirator. Accordingly,
CSHOs must be able to tolerate the physical and psychological stress imposed by
respirator use, as well as the physical stress originating from job and workplace
- General Requirements. Many factors must be carefully considered in
selecting a respirator. In choosing the appropriate respirator, one must
consider the nature and extent of the hazard, work requirements and
conditions, and the characteristics and limitations of the available
respirators. The following information must be taken into account:
- Nature of the hazard, and the physical and chemical properties of
the air contaminant;
- Concentrations of contaminants;
- Relevant permissible exposure limit or other occupational exposure
- Nature of the work operation or process;
- Length of time the respirator is worn;
- Work activities and physical/psychological stress;
- Fit testing; and
- Physical characteristics, functional capabilities, and limitations of
The program administrator will make a respirator available to each CSHO
who is assigned a job that requires respiratory protection. All respirators
selected must be certified by NIOSH and must be used in accordance with
the terms of that certification, which appears on the NIOSH certification
label. Under certain circumstances, OSHA may permit the use of
respirators not approved by NIOSH (i.e., where no NIOSH-approved
respirator exists) where documentation exists to attest to the adequacy of
the respirator's effectiveness against the contaminant(s) of concern. The
National Office will examine those situations on a case-by-case basis.
Replacement respirators, cartridges, canisters, and filters will be made
available as required. All filters, cartridges, and canisters must be labeled
with the appropriate NIOSH approval label. The label must not be
removed or defaced while the respirator is in use.
- Non-IDLH Atmospheres. For protection against gases and vapors in
atmospheres that are non-IDLH, an air-purifying respirator should be used.
When an air-purifying respirator is selected, a system must be in effect
that will reliably protect respirator wearers from contaminant
breakthrough. These systems are:
- A respirator equipped with a NIOSH-approved end-of-service life
indicator (ESLI) for the particular contaminant; or
- If there is no ESLI appropriate for the conditions encountered at a
worksite, the CSHO follows a sorbent change schedule for
canisters and cartridges based on reliable information or data
ensuring that canisters and cartridges are changed before the end of
their service life.
In many cases, CSHOs may need to don respirators before recognizing all
of the conditions of the work area or having access to the information
needed to develop a good change-out schedule. Compliance officers
should be urged to carry to each jobsite extra cartridges or canisters and to
err on the side of caution. CSHOs should obtain as much information on
the chemical hazards in the workplace as possible, and they should consider
the employer's change-out schedule, if one is available, since it will have
been created with that site in mind. If the gases and/or vapors have sensory
warning properties such as odor, taste, and/or irritation effects, and the
CSHO detects "breakthrough," the CSHO must leave the respirator use area
and the cartridge or canister must be immediately replaced before the
CSHO returns to the work area.
Some gaseous contaminants will migrate across the adsorbent or absorbent
bed while the respirator is not in use, such as overnight. This migration can
subject the user to an initial dose of the contaminant when the respirator is
again placed in service. Therefore, as a minimum, gas vapor cartridges and
canisters should be disposed of after each day's activities no matter how
short those activities were.
Experience and professional judgment should be used along with existing
information and data to establish cartridge or canister change schedules. If
further information is needed in establishing a change-out schedule then the
program administrator and /or CSHO can consult the OSHA website at (http://www.osha.gov/SLTC/etools/respiratory/change_schedule.html) or
the manufacturer's website if one exists.
For protection against particulate contaminants in atmospheres that are non-IDLH, a CSHO should use an air-purifying respirator equipped with filters
certified for particulates by NIOSH under 42 CFR part 84. Filter cartridges
should be replaced when the breathing resistance becomes great enough to
cause discomfort to the wearer (overloaded) or when the cartridge suffers
physical damage compromising its integrity.
- Use of SCBAs. The use of SCBAs by CSHOs is strongly discouraged.
If a worksite needs to be entered where an SCBA is required, the Health
Response Team should be contacted for assistance. Only those CSHOs
who are medically certified to wear an SCBA may do so. In addition,
CSHOs must be adequately trained in the use of the equipment and the
equipment must be properly maintained. Compressed breathing air must
meet at least the requirements for Grade D breathing air described in
ANSI/Compressed Gas Association Commodity Specification for Air, G
The ARA/TS must be consulted for assistance in determining the
appropriateness of SCBA use in a specific situation. Any planned entry
involving the use of SCBA must be coordinated with the ARA/TS.
- Entry into IDLH Atmospheres. CSHOs are not allowed to enter known
IDLH atmospheres for inspection purposes. OSHA personnel are not
emergency responders and are not authorized to act in such a manner.
Evaluation methods (i.e., sampling strategies) should be used which do not
require entry into an IDLH area.
- Emergency Escape from IDLH Atmospheres. Escape-only respirators must
be carried by all individuals when there is a potential for exposure to IDLH
atmospheres. This type of situation may exist in portions of refineries,
chemical plants, sewage treatment plants, and hazardous waste sites, etc.
All escape-only respirators have limitations and these limitations must be
taken into account when selecting them.
Respirators that are to be used exclusively for escape from IDLH
atmospheres are to be selected from those certified by NIOSH for escape
from the atmosphere in which they will be used. If the toxic materials in
question can cause eye irritation, then a full facepiece or hood must be
used. For example, under current 29 CFR 1910.1050, the standard
governing exposure to methylenedianiline (MDA), escape respirators may
be any full facepiece air-purifying respirator equipped with high-efficiency
particulate air (HEPA) cartridges or any positive pressure or continuous
flow self-contained breathing apparatus with full facepiece or hood. For
formaldehyde exposure, escape respirators may be a full facepiece with
chin style, front, or a back-mounted industrial canister approved against
formaldehyde (29 CFR 1910.1048). If an escape SCBA is selected for a
potential IDLH atmosphere, the CSHO must assess the egress route to
ensure that the emergency egress time does not exceed the capacity of the
- Purpose. The purpose of a medical evaluation is to determine if CSHOs
can tolerate the physiological burden associated with respirator use,
including: the burden imposed by the respirator itself (e.g., its weight and
breathing resistance during both normal operation and under conditions of
filter, canister, or cartridge overload); musculoskeletal and
cardiopulmonary stress (e.g., when the respirator to be worn is an SCBA);
limitations on hearing, sight, or smell; and isolation from the workplace
environment. Since certain jobs and workplace conditions in which a
respirator is used can also impose a physiological burden on the user, the
medical evaluation must also consider the following factors: type and
weight of the respirator to be worn; duration and frequency of respirator
use; expected physical work effort; use of protective clothing and
equipment to be worn; and temperature and humidity extremes that may be
- Respirator Wear Evaluation. CSHOs must be medically evaluated and
found eligible to wear the respirator selected for their use prior to fit testing
and first-time use of the respirator in the workplace.
- Medical Eligibility Determination. Medical eligibility is to be determined
by adhering to the following OSHA programs:
- CSHO Pre-employment Medical Examinations (OSHA Instruction
PER 8-2.4), and
- CSHO Medical Examinations (PER 8-2.5)
Both of these programs are medical evaluations that certify ability to use a
respirator. The medical examination will be conducted by a physician
experienced in occupational medicine. Regional Administrators and Area
Directors are responsible for implementing the CSHO Medical
The CSHO pre-employment medical examination (PER 8-2.4) is
required for new hires so that the Agency can determine if they are
physically and medically capable of performing the essential duties
of their position efficiently and without a hazard to themselves or
others. The examination will be provided free of charge to the
applicant. Failure to meet the required physical and medical
qualifications will be considered disqualifying.
A periodic CSHO medical examination is required for current OSHA
employees in accordance with OSHA Instruction PER 8-2.5. Student
trainees are covered under this program if their tenure with the Agency is
expected to exceed a year from their initial (pre-employment) examination.
Annual examinations and any additional medical exam necessary will be
scheduled by the Area Director/Supervisor and will be conducted during
The medical evaluation is designed to identify medical conditions that
place CSHOs who use respirators at risk of serious medical consequences.
Medical conditions known to compromise an employee's ability to tolerate
respirator-, job-, and workplace-related physiological stress include:
cardiovascular and respiratory diseases (e.g., a history of high blood
pressure, angina, heart attack, cardiac arrhythmias, stroke, asthma, chronic
bronchitis, emphysema); reduced pulmonary function caused by other
factors (e.g., smoking or prior exposure to respiratory hazards);
neurological or musculoskeletal disorders (e.g., ringing in the ears,
epilepsy, lower back pain); impaired sensory function (e.g., perforated ear
drums, reduced or absent ability to smell); and psychological disorders
(e.g., claustrophobia and severe anxiety).
Reevaluation of CSHO Ability to Use a Respirator. In addition to the
annual medical evaluation there are a number of circumstances that may
require reevaluating a CSHOs ability to use a respirator. Medical
reevaluations will be provided under the following conditions: when the
CSHO reports medical signs or symptoms that are relevant to the CSHOs
ability to use a respirator; when OSHA management informs the examining
physician that a CSHO needs to be reevaluated; when information from the
respirator program, including observations made during fit testing or
program evaluation, indicates a need for CSHO reevaluation; or when a
change in workplace conditions occurs (e.g., physical work effort,
protective clothing, temperature) that may result in a substantial increase in
the physiological burden placed on a CSHO.
Reporting Results of Examinations. The examining physician must
forward to the Office of Occupational Medicine the results of the medical
examination. The Office of Occupational Medicine will review the
findings of the examination and determine whether or not the CSHO is fit
to use a respirator. In addition, the examining physician will generate a
personal medical report for each CSHO/applicant examined and mail a
copy to their private residence within 15 working days of the date of the
Respirator Use. It is necessary to ensure that respirators are used properly on
inspections. CSHOs must use their respirators under conditions specified by the
respiratory protection program and in accordance with the training they receive. In
addition, the respirator must not be used in a manner for which it is not certified by
NIOSH or by its manufacturer.
- Purpose. The primary purpose of fit testing is to identify the specific make,
model, style, and size of respirator best suited for each CSHO. In addition,
fit testing also reinforces respirator training by having wearers review the
proper methods of donning and wearing the respirator. CSHOs must be
medically evaluated and found eligible to wear the respirator selected for
their use prior to fit testing.
- Requirements. Fit testing is required for all negative or positive pressure
tight-fitting facepiece respirators. The OSHA respiratory protection
standard requires that fit testing be performed before an employee first
starts wearing a respirator in the work environment, whenever a different
respirator facepiece is used, and at least annually thereafter.
- Demonstrating and Selecting a Respirator Model. Prior to the actual fit
test, the CSHO must be shown how to put on a respirator, position it on the
face, set strap tension, and determine an acceptable fit. Next, the CSHO
must be allowed to choose a respirator from a sufficient number of models
and sizes so that the CSHO can find an acceptable and correctly fitting
respirator. Once an acceptable respirator has been found -- which takes
into account the position of the mask on the face, nose, and cheeks; room
for eye protection; and room to talk -- a user seal check must be conducted
(refer to next section on "Respirator Use").
- Protocols. Fit testing may be either qualitative (QLFT) or quantitative
(QNFT), and must be administered using an OSHA-accepted QLFT or
QNFT protocol. Usually most CSHOs will be quantitatively fit tested as
each Area and Regional Office has access to a PortacountTM unit.
- Protocol Descriptions. QLFT and QNFT protocols are described in
mandatory Appendix A to 1910.134, and must be incorporated into all
Regional and Area Office Programs. QLFT may only be used to fit test
negative-pressure air-purifying respirators that must achieve a fit factor of
100 or less. If the fit factor, as determined by QNFT fit testing, is equal or
greater than 100 for tight-fitting half facepieces, or equal to or greater than
500 for tight-fitting full facepieces, then the QNFT has been passed with
- Preliminary Steps. Prior to the commencement of the fit test, the CSHO
must be given a description of the fit test and a description of the exercises
that he or she will be performing during fit testing. The respirator to be
tested must be worn for at least five minutes before the start of the fit test.
The CSHO must be fit tested with the same make, model, style, and size of
respirator that will be used. CSHOs assigned more than one respirator
must be fit tested for each respirator assigned.
- Changing Respirator Model Selection, Retesting. If the CSHO finds the fit
of the respirator to be unacceptable, he or she must be given a reasonable
opportunity to select a different respirator and to be retested. In addition,
retesting is required whenever there are changes in a CSHO's physical
condition that could affect respirators fit. Such conditions include, but are
not limited to, facial scarring, dental changes (e.g., wearing new dentures),
cosmetic surgery, or an obvious change in body weight.
The following conditions compromise the effective use of the respirator and
jeopardize worker protection: facepiece seal leakage; removing the respirator while
in hazardous atmospheres; not properly performing user seal checks; or not
properly repairing defective parts.
Maintenance and Care Program. To ensure that the respirator remains serviceable
and delivers effective protection, a maintenance program must be in place prior to
respirator use. In addition to the OSHA requirements, the manufacturer's
instructions for inspecting, cleaning, and maintaining should be consulted to ensure
that the respirator continues to function properly. A proper maintenance program
ensures that the CSHO's respirator remains as effective as when it was new. The
maintenance program should be tailored to the type of facilities, working
conditions, and hazards involved, but all programs are required to include at least:
- Facepiece Seal Protection. All CSHOs must conduct a user seal check
(formerly known as a fit check) every time a tight-fitting respirator is put
on or adjusted to ensure that the respirator is seated properly on the face
with no noticeable leaks. The user seal check procedure conducted must be
either the positive and/or negative pressure checks described in Appendix
B-1 of 1910.134, or the manufacturer's recommended procedures (when
equally protective). If leaks are present, the CSHO should adjust the
respirator and try again.
Respirators with tight-fitting facepieces may not be worn by CSHOs who
have conditions that would compromise the facepiece-to-face seal.
Examples of these conditions include facial hair (e.g., beard stubble,
sideburns, or beard) that interferes with the facepiece seal or valve function,
absence of normally worn dentures, facial deformities (e.g., scars, deep skin
creases, prominent cheekbones), or the use of jewelry or headgear that
projects under the facepiece seal.
Corrective glasses or goggles, or other personal protective equipment, must
be worn in such a way that does not interfere with the seal of the facepiece
to the face. It should be noted that in some cases a full-facepiece respirator
or powered air-purifying respirator (PAPR) may be more comfortable and
less cumbersome than the combination of a half-mask and chemical
goggles. OSHA's current standard on respiratory protection allows the use
of contact lenses with respirators where the wearer has successfully worn
such lenses before.
- Skin or Eye Irritation. Skin or eye irritation can result from wearing a
respirator in hot, humid conditions as well as in contaminated
environments. Such irritation can cause considerable distress to CSHOs,
causing them to remove or adjust the respirator or to refrain from wearing
the respirator at all, thereby rendering it ineffective. To prevent skin or eye
irritation associated with respirator use, CSHOs should leave the respirator
use area to wash their faces and respirator facepieces as needed.
- Vapor or Gas Breakthrough. Whenever the CSHO can detect vapor or gas
breakthrough (by odor, taste, and/or irritation effects) or a change in
breathing resistance or leakage of the facepiece, the CSHO must leave the
respirator use area to replace the respirator or the filter, cartridge, or
canister elements. Similarly, CSHOs must leave the respirator use area if
they are replacing cartridge or canister elements according to a change
schedule, or when the end-of-service-life indicator shows that the canister
or cartridge(s) must be changed.
- Impairments. Because respirators must be in good working condition to
function, they should not be used if they have been impaired in any way.
Impairments include a broken strap, loss of respirator shape, and a face seal
that can no longer be maintained. Respirators that are not properly
functioning must be replaced, repaired, or discarded.
CSHO Responsibilities for Maintenance and Care. CSHOs must clean and inspect
their own respirators in accordance with the provisions of this program. Maintenance involves a thorough visual inspection for cleanliness and defects.
Worn or deteriorated parts must be replaced prior to use. No components are to be
replaced or repairs made beyond those recommended by the manufacturer. Repairs
to regulators or alarms of atmosphere-supplying respirators are to be conducted by
- Cleaning and disinfecting procedures;
- Proper storage;
- Regular inspections for defects; and
- Repair methods.
Training. Training is an important part of the respiratory protection program and is
essential for correct respirator use. OSHA personnel must receive training prior to
using a respirator. For the training to be effective, the training must be
comprehensive and presented in an understandable way.
- Cleaning. Cleaning and sanitizing respirators is necessary to prevent skin
irritation and dermatitis. Where the contaminant is a dust, mist, or fume, its
build-up on the respirator face-to-facepiece seal or within the respirator can
reduce the protection provided by the respirator because the contaminant is
in the breathing zone or has compromised the seal. In addition, the build-up of contamination on the respirator can contribute to the deterioration of
the respirator's materials, which can lead to reduced protection.
Respirators that are issued for the exclusive use of a CSHO must be cleaned
and disinfected as often as necessary to remain sanitary. Respirators used
by more than one employee must be cleaned and disinfected prior to being
used by a different individual. Respirators maintained for escape-only use,
as well as respirators used in fit testing and training, must be cleaned and
disinfected after each use.
The CSHO must use either the cleaning and disinfecting procedures
recommended in Appendix B-2 of the OSHA respiratory protection
standard or the procedures recommended by the respirator manufacturer, as
long as they are equivalent in effectiveness to the OSHA method.
Equivalent effectiveness simply means that the procedures used ensure that
the respirator is properly cleaned and disinfected in a manner that prevents
damage to the respirator and does not cause harm to the user. The program
administrator will ensure an adequate supply of the appropriate cleaning
and disinfecting agents are maintained at the cleaning station.
- Storage. All respirators must be stored so that they are protected against
damage, contamination, dust, sunlight, extreme temperatures, excessive
moisture, and damaging chemicals. Filter cartridges must be stored
separately from respirator facepieces that have been cleaned. This is to
prevent contamination of the interior of the respirator facepiece from
hazardous particulate matter (e.g., lead, asbestos, cadmium, silica) that may
have accumulated on the filter cartridge. When respirators are packed or
stored, the facepiece and exhalation valve must be stored in a manner that
will prevent deformation. Each respirator should be positioned so that it
retains its natural configuration. Synthetic materials and even rubber will
warp if stored in an unnatural shape, thus affecting the fitting
characteristics of the facepiece.
- Inspection. To ensure the continued reliability of respiratory equipment,
they must be inspected on a regular basis.
- All Respirators. For all respirators, inspections must include a
check of respirator function, tightness of connections, and the
condition of the various parts including, but not limited to, the
facepiece, head straps, valves, connecting tube, and cartridges,
canisters, or filters. In addition, the elastomeric parts must be
evaluated for pliability and signs of deterioration.
- SCBAs. SCBAs require monthly inspections. The air and oxygen
cylinders must be maintained in a fully charged state and recharged
when the pressure falls to 90% of the manufacturer's recommended
pressure level. In addition, the regulator and warning devices must
be inspected to ensure that they function properly. For SCBAs
maintained for emergency use a record of the monthly inspection
must be maintained by the program administrator. The record must
include the date of the inspection, the name of the inspector, the
findings of the inspection, any required remedial action, and a serial
number or other means of identifying the inspected respirator.
- Inspection Frequency. The frequency of inspection and the procedures to
be followed depend on whether the respirator is intended for routine use or
- Routine Use. All respirators used in routine situations must be
inspected before each use and during cleaning.
- Escape-Only Use. Respirators used for escape-only must be
inspected before being carried onto the jobsite.
- Repair. Respirators that fail to pass inspection or are otherwise found to be
defective must be removed from service, and discarded, repaired, or
adjusted. Repairs or adjustments to respirators must be done only by
appropriately trained personnel, using only the respirator manufacturer's
NIOSH-approved parts designed for that respirator. The repairs also must
be made in accordance with the manufacturer's recommendations and
specifications regarding the type and extent of repairs to be performed.
Because components such as reducing and admission valves, regulators,
and alarms are complex and essential to the safe functioning of the
respirator, they are required to be adjusted and repaired only by the
manufacturer or a technician trained by the manufacturer. When a
respirator is taken out of service, the respirator must be tagged "out of
service," and the CSHO should be given a replacement of the same make,
model and size.
All program administrators must attend the OSHA Training Institute (OTI) course
on respiratory protection or an equivalent course. The program administrator or
other qualified individual will provide the necessary training to all CSHOs who
may be assigned to wear respirators. Additional training may also be provided
through completion of an OTI course in respiratory protection or other training
source. As a result of this training, all personnel will be able to understand the
operation of the respirator and be able to use it properly.
The training must cover, at a minimum, the following topics:
Annual Retraining and Refresher Training. Retraining must be done annually and
under some conditions additional retraining might be required. Circumstances
which would require retraining include situations where changes in the type of
respirator assigned to the employee render previous training obsolete; when the
employee has not retained the requisite understanding or skill to use the respirator
properly; or any other situation in which retraining appears necessary to ensure
safe respirator use.
- The general requirements of the OSHA respiratory protection standard;
- A discussion of why the use of the respirator is necessary. Such training
should address the identification of the hazards involved during
inspections, the extent of employee exposures to those hazards, and the
potential health effects of such exposures;
- Proper selection of respirators;
- The procedures for inspecting the respirator, donning and removing it,
checking the fit and seal, and actually wearing it;
- Information regarding the consequences of improper fit, usage, or
- Limitations and capabilities of the respirator selected, including ESLI and
- How to use the respirator effectively in emergency situations, including
situations when malfunctions occur;
- Proper procedures for maintenance and storage; and
- How to recognize medical signs and symptoms that may limit or prevent
the effective use of respirators (e.g., shortness of breath, dizziness).
For example, training in the operation and use of SCBAs must be ongoing and
continuous. Individuals who are designated to use SCBA must follow the
manufacturer's instructions and be trained annually. Training must include the
wearing and use of SCBA during exercise situations (e.g., walking). All respirator
training will be documented by the program administrator and the documentation
will include the type, model, and size of the respirator assigned to each employee.
Program Evaluation. The program administrator must conduct evaluations of the
respiratory protection program as necessary to ensure that the provisions of the
current written respirator program are being properly implemented for all CSHOs
required to use respirators. Evaluations must be conducted to ensure the continued
effectiveness of the program. Evaluations of the program will determine whether
the correct respirators are being used and worn properly and whether the training
program is effective.
The program administrator must regularly consult with CSHOs wearing respirators
to ascertain the employees' views on program effectiveness and to identify any
problems. This assessment must determine if the respirators are properly fitted. It
must also evaluate whether CSHOs are able to wear the respirators without
interfering with effective workplace performance; respirators are correctly selected
for the hazards encountered; respirators are being worn when necessary; and
whether respirators are being maintained properly. The program administrator
must correct any problems associated with wearing a respirator that are identified
by CSHOs or that are revealed during any other part of this evaluation.
Record keeping. SCBAs require monthly inspections. The air and oxygen
cylinders must be maintained in a fully charged state and recharged when the
pressure falls to 90% of the manufacturer's recommended pressure level. In
addition, the regulator and warning devices must be inspected to ensure that they
function properly. For SCBAs maintained for emergency use a record of the
monthly inspection must be maintained by the program administrator. The record
must include the date of the inspection, the name of the inspector, the findings of
the inspection, any required remedial action, and a serial number or other means of
identifying the inspected respirator. The Director of the Office of Occupational
Medicine must ensure that all procedures for review and handling of OSHA
medical records are in accordance with OSHA standard 29 CFR 1910.1020,
"Access to Employee Exposure and Medical Records" and the Office of Personnel
Management's 5 CFR 293, Subpart E, "Employee Medical File System Records."
This includes establishing and maintaining a confidential storage and retrieval
system so that individual records can be kept.
The CSHO's Area Director or supervisor must receive a copy of the written
medical opinion for each CSHO who will wear a respirator so that they have
knowledge of the CSHO's ability to wear a respirator. The CSHO should also be
provided with a copy. The program administrator must keep a copy of the written
opinion as well as other records (i.e., fit testing and the written respirator program)
required under 29 CFR 1910.134. This information will assist the program
administrator in auditing the adequacy of the program.
Fit test records must be retained for respirator users until the next fit test is
administered. These records consist of:
- Name of the person tested;
- Type of fit test performed (QLFT, QNFT - irritant smoke, saccharin, etc.);
- Make, model, and size of the respirator fitted;
- Date of the fit test;
- Pass/fail results if a QLFT is used; and
- Fit factor and strip chart recording or other record of the test results if
quantitative fit testing was performed.
Fit test records must be maintained to determine whether annual fit testing has
been done, and whether the employee tested passed the QLFT or passed the QNFT
with a fit factor that was appropriate for the type of respirator being used. If the
employee's use of a respirator is discontinued (e.g., because of a change of duties
or termination), fit test records need not be retained.
All written materials required to be maintained under the record keeping
requirements must be made available, upon request, to affected CSHOs for
examination and copying.
