Photos shown in this presentation may depict situations that are not in compliance
with applicable OSHA/MSHA/FHWA requirements.
It is not the intent of the content developers to provide compliance-based training in
this presentation, the intent is more to address hazard awareness in the construction
and mining industry, and to recognize the overlapping hazards present in many
workplaces.
It should NOT be assumed that the suggestions, comments, or recommendations
contained herein constitute a thorough review of the applicable standards, nor
should discussion of “issues” or “concerns” be construed as a prioritization of
hazards or possible controls. Where opinions (“best practices”) have been expressed,
it is important to remember that safety issues in general and jobsites specifically will
require a great deal of site- or hazard-specificity – a “one size fits all” approach is not
recommended, nor will it likely be very effective.
No representation is made as to the thoroughness of the presentation, nor to the
exact methods of remediation to be taken. It is understood that site conditions vary
constantly, and that the developers of this content cannot be held responsible for
safety problems they did not address or could not anticipate, nor those which have
been discussed herein or during physical presentation. It is the responsibility of the
employer, its subcontractors, and its employees to comply with all pertinent rules
and regulations in the jurisdiction in which they work.
It is assumed that individuals using this presentation or content to augment their
training programs will be “qualified” to do so, and that said presenters will be
otherwise prepared to answer questions, solve problems, and discuss issues with their
audiences.
Areas of particular concern (or especially suited to discussion) have additional
information provided in the “notes” section of slides throughout the program…as a
presenter, you should be prepared to discuss all of the potential issues/concerns, or
problems inherent in those photos particularly.

Employer must select and provide an appropriate respirator
based on respiratory hazards worker is exposed to, workplace
and user factors
Respirator shall be certified by NIOSH and used in compliance
with certification
Identification and Evaluation of Respiratory Hazards
Nature of Contaminant/Contaminant Involved
Estimate of employee exposure
If there is no basis or adequate information for employee exposure
assessment, assume IDLH
Contaminant’s chemical and physical state
Human capabilities
Work condition
Select respirators from a sufficient number of models/sizes
An atmosphere that poses an immediate
threat to life, would cause irreversible health
effects or would impair an individual’s
ability to escape from a dangerous
atmosphere
Oxygen Deficient Atmosphere
Toxic Levels that exceed the Permissible
Limit
Exposure
If an IDLH atmosphere exists, select:
A full facepiece pressure demand SCBA certified by
NIOSH for 30 minutes minimum service life or
A combination full facepiece pressure demand Supplied
Air Respirator or
Escape-only respirators from IDLH atmospheres shall be
NIOSH certified for escape from the atmosphere in
which they will be used
Note: Employers may use any atmosphere supplying
respirator provided they can demonstrate oxygen levels
are maintained at 19.5% and 16% partial pressure
equivalent
For protection against gases and vapors, employers must
provide:
An atmosphere-supplying respirator
An air-purifying respirator, provided that:
Respirator is equipped with ELSI (End of Service Life
Indicator) certified by NIOSH for that contaminant
Change-out schedule is provided for canisters and
cartridges based on objective data that will ensure they
will be changed before end-of-service life when there is
no ESLI
Employer must describe information and data with
basis for change schedule
For protection against particulates, employers must
provide:
An atmosphere supplying respirator
An air-purifying respirator equipped with HEPA filters
certified by NIOSH or with filters certified by NIOSH
for particulates
An air-purifying respirator equipped with any filter
certified for particulates by NIOSH for contaminants
consisting primarily of particles with mass median
aerodynamic diameters of at least 2 micrometers
Levels of filter efficiency are 95%, 99%, and 99.97%
Number is dependent on how much filter leakage can be
accepted
Categories of resistance to filter efficiency degradation
are labeled N, P and R
N ~ Not resistant to Oil
R ~ Resistant to OIL
P ~ Oil-Proof
If no oil particles are present, use any of the above
If oil particles are present, use only R or P
If oil particles are present and the filter is to be used for more
than one work shift, use only P series
Must be provided to determine the employee’s ability to use a
respirator
Must be completed before fit testing and use
A PLHCP must be identified to perform medical evaluations
through:
A medical questionnaire
Initial medical examination
The medical evaluation must obtain information requested
in Appendix C Part A Sections 1 and 2
Follow-up medical examination is required when:
Employee answers “Yes” to Question 1 - 8 in Section 2, Part A of
Appendix C
Initial medical examination demonstrates need for follow-up
Annual review of medical status is not required
Medical evaluations must be provided at a minimum if:
Employee reports medical signs or symptoms related to the
ability to use a respirator
PLHCP, supervisor or Program Administrator informs
employer of employee reevaluation
Information from respirator program indicates a need for
reevaluation
Program evaluation
Observations made during fit testing
Changes in workplace conditions may increase physiological
burden
Employee must be fit tested with same, make, model, and size of
respirator that will be used before any use commences with a positive
or negative pressure tight fitting facepiece
Employees must pass a Qualitative Fit Test (QLFT) or a Quantitative
Fit Test (QNFT)
Prior to initial use
Whenever different respirator is used
At least annually thereafter
Additional fit test must be conducted when the employee’s physical
condition changes that could affect fit of respirator
Facial scarring
Dental Changes
Cosmetic Surgery
Change in Body Weight
A pass/fail fit test to assess the adequacy of the
respirator fit. This test relies on the individual’s
response to the test agent
May only be used to fit test negative pressure APR’s
that must achieve a fit factor of 100 or less
Testing agents include:
Isoamyl Acetate
Saccharin
Bitrex
Irritant Smoke
Assessment of the adequacy of the respirator fit by
numerically measuring the amount of leakage into the
respirator
If fit factor is determined to be equal to or greater than
100 for tight fitting half facepieces or equal to or
greater than 500 for tight fitting full facepieces, the
QNFT has been passed with that respirator
Fit Factor = Concentration of Substance in Ambient
Air
Concentration inside respirator when
worn
Employees that wear tight fitting respirators shall not
have facial hair or any condition that interferes with
the face-to-facepiece seal or valve function
Corrective glasses or goggles must not interfere with
the face-to-facepiece seal
Positive and Negative Seal Checks must be performed
each time the respirator is donned
Follow procedures in Appendix B-1
The effectiveness of the respirator must be evaluated
through appropriate surveillance of the work area
conditions and the degree of exposure or stress
Employees must leave the respirator use area:
To wash their faces and respirators as necessary
If gas or vapor breakthrough is detected
If breathing resistance is detected
If there is leakage of the facepiece
To replace respirator, filter, cartridge or canister
Employee cannot re-enter area until respirator is
replaced or repaired
Provide each user with a respirator that is clean, sanitary
and in good working order
Follow Appendix B-2 or manufacturer’s recommendations
Clean and disinfect as follows:
As often as necessary when issued for exclusive use
Before being worn by different individuals when issued to
more than one employee
After each use for emergency respirators and those used in fit
testing and training
Protect from:
Sunlight
Damage
