QUIZ
OSHA Respiratory Protection
Standard
• Standard 29 CFR 1910.134
• Assess the workplace and provide respirators
when necessary to protect the health of
employees
• Develop and implement a written respiratory
protection program
• Provide training on how to properly use
respirators
• Provide medical evaluations at no cost to the
The Lungs
• Inhalation is the most direct
route to the bloodstream
• Inhalation of hazardous
materials damages the delicate
structures of the lungs
• Damaged lungs are more
susceptible to respiratory
disease
Respiratory Hazards
• Respiratory protection is required when
employees are in areas where effective
engineering controls are not feasible to
protect the health of the employee from :
– lack of oxygen
– harmful dusts, fogs, fumes, mists, gases,
smokes, sprays or vapors
• Respiratory Protection must comply with
NIOSH/MSHA
Respiratory Protection
• Exposure levels exceed PEL
• During installation of engineering or
work practice controls
• Maintenance and repair activities that
may result in exceeding the PEL
• Emergency Response where type
and/or concentration of contaminant is
unknown
• Voluntary Usage
Voluntary Use of
Respirators
• ECU may provide respirators at the
request of the employees or permit
employees to use their own respirators
• The University must ensure that any
employee using a respirator voluntarily
is medically able to use that respirator
Voluntary Use of
Respirators
Employee precautions:
• Read instructions on use, maintenance,
cleaning and care, and warnings
• Use NIOSH certified respirators only
• Wear respirators designed for your specific
use
• Keep track of respirator so you do not
mistakenly use someone else’s
Medical Surveillance
• Medical evaluations must be provided
to determine each employee’s fitness to
wear a respirator
• These evaluations are required for all
respirator users except for employees who
voluntarily use dust masks and for the use of
escape-only respirators
• Medical evaluation records will be retained for
30 years beyond the employee’s employment
Respirator Selection
The selection of respirators depends on
what the hazard is and its extent,
choosing approved equipment, and
ensuring the device is certified.
Respirator Selection
• Chemical & physical properties of the
contaminant
• Toxicity & concentration of hazardous
material
• Amount of oxygen present
• Limitations & characteristics of available
respirators

Combination
Proper Wear
Employers shall not permit the use of
respirators for employees that:
• Have facial hair that interferes with the
seal or valve function of the respirator
• If PPE is used such as corrective
glasses, the employer will ensure that
the PPE will not interfere with the seal
of the respirator
Criteria for
Determining Comfort
• mask position on nose
• room for eye protection
• room to talk
• mask position on face
and cheeks
Criteria for Determining
Adequacy of Fit
• Chin properly placed
• Adequate strap tension, not too tight
• Fit across nose bridge
• Respirator of proper size to span distance
from nose to chin
• Tendency of respirator to slip
• Self-observation in mirror to evaluate fit and
respirator position
Fit Testing
• Fit testing is required for all employees
using negative or positive pressure tightfitting respirators
• Must be repeated annually and
whenever a different respirator is used
• Qualitative Fit-Testing is used for this
program
Fit Testing
• Employee shall be allowed to pick the most
acceptable respirator from all the models and
sizes that will provide most adequate protection
• Fit test shall be performed wearing any
applicable safety equipment that may be worn
during actual respirator use
• No respirator will provide adequate protection
without a tight seal between the facepiece and
the face of the wearer
Fit Testing
• Employer shall demonstrate:
– how to put on a respirator
– how it is positioned
– how to set strap tension
– how to determine an acceptable fit
• Employee shall conduct:
– Negative seal check
– Positive seal check
Fit Test Exercises
•
•
•
•
•
•
•
Normal breathing
Deep breathing
Turning head side to side
Moving head up and down
Talking
Grimace (smile or frown)
Bending over
Taste Threshold Screening
• EH&S will conduct a Taste Threshold
Screening to help determine adequate fit of the
respirator
• If the test fails, a different respirator must be
tried
Respirator
Maintenance
All respirators must be cleaned, stored and
inspected regularly. This is necessary to
provide complete protection.
Cleaning
• Must be cleaned regularly
• Respirator should be cleaned and
disinfected if used by more than one
person
• Disassemble the respirator and
soak in warm water and rinse
with clean water
• Respirators may be washed in a
detergent solution and then disinfected
in a sanitizing solution
• Air dry all parts of the respirator or wipe
Storage
• Respirators must be stored to protect
against dust, sunlight, temperature,
moisture, and chemicals
• Not to be stored in lockers
or tool boxes
• Stored so that facepiece and
valves will rest in a normal position
• Respirators should not be stored by
hanging them by the headband
Inspection
• Respirators should be inspected before
and after each use to ensure all parts
are present and operating
• Rubber and elastomer parts should be
checked for pliability and signs for
deterioration
• Any worn or deteriorated parts should
be replaced-cracks, tears, holes ,
gaskets
Special Maintenance
Features
• Filters and cartridges must
be changed periodically
• All filters must be properly
labeled and color coded
• Self-contained breathing apparatus
must be inspected monthly
• Use of SCBA’s is restricted to
employees of the Office of
Environmental Health and Safety
Use and Limitations
• The respirator is the last control measure to
ensure safety to the employee
• The respirator is necessary to prevent the
inhalation of aerosols and contaminants
• Employees must be familiar with the
respirator and its operations
• The respirator must have a proper seal and
effective valves in order to perform its job
Use and Limitations
Use and limitation information for the
respirators utilized in this program include
the following:
• Employees must leave the area if the
contaminant can be detected by dizziness
• If the respirator is damaged or breathing
becomes difficult, the employee must
leave the area
• Not all respirators supply oxygen to
employees
• The manufacturer’s operation manual
Program Evaluation
The Respiratory Protection Program will be
evaluated annually by the Office of
Environmental Health and Safety
Factors that will be assessed include:
• Respirator fit
• Appropriate respirator selection for the hazards
to which the employee is exposed
• Proper respirator use under the workplace
conditions the employee encounters
• Proper respirator maintenance

21
Using SCBAs –
Special Notes
SCBAs are sophisticated respirator equipment
used for possible or actual life-threatening
situations.
SCBAs should not be used without extensive
hands-on training and frequent re-training.
Most SCBA manufacturers or distributors
provide this training.
If you have large chemical spill or leak, it may
be safer to call professional emergency
responders.
22
Air Quality For SCBAs
Air for breathing must be “Grade D” air
Grade D air for tanks is usually
purchased from a specialized
supplier.
Grade D air must meet strict
requirements. link to WISHA
requirements
Supplier must certify that tank air
meets Grade D requirements.
23
Air Quality for Airline
Respirators
Air compressors
must deliver clean air
Locate pump intake in an area of
clean, fresh air.
Filter air as needed.
Watch out for nearby running
engines.
Small electric air pump
Be sure air intakes are located
away from exhaust pipe of an
engine compressor.

compressors with caution
Be careful – these do not provide
clean air without a filter system!!
Oil-lubricated compressor are
especially hazardous. Must test
for carbon monoxide or have high
temperature alarm.
Engine exhaust can also
contaminate breathing air.

Compressor Air Filters
What air filters are needed on compressors?
Moisture trap
Dust filter
compressor filters
Hydrocarbons(oil, solvents)
absorbent
Carbon monoxide alarm or hightemp. alarm for oil-lubricated
compressors

Storage and
Maintenance
Airline Respirators
Store facepiece and regulator in
clean, dry place.
Coil up hose and store in protected
area to prevent damage.
Clean as needed before storage –
especially the inside of the
facepiece.
Inspect facepiece and hose for
damage and replace as needed.
29
Supplied air
respirator repairs
Keep spare parts available.
Tag damaged respirators to prevent
use.
Repair of SCBA valves, regulators or
alarms can only be done by
manufacturer’s trained person.

Dust Masks
• May be worn for comfort
• Must be replaced when breathing becomes
difficult; smell/taste contaminants;
experience distress; anything abnormal
• Properly dispose of mask by cutting straps
• Do not wear another person’s mask
