4. Respiratory Protective Equipment
Types of Respirators
Air-purifying respirators – Utilized on this campus
» Filters (for particulates)
» Cartridges (for gases or vapors) may have filters as well
» Canisters (used with “gas masks” – large capacity)
» Oxygen must be > 19.5%
Atmosphere supplying respirators – Not utilized on this campus
» SCBA’s (self-containing breathing apparatus)
» Supplied air respirators (Type C or CE)
» Combinations of SCBA’s and SARS’s

5. Air-Purifying respirators
Disposable (Dust) Masks
Single-use
With Valve Without

6. Air-Purifying Respirators
Half Face Respirators
Design allows for better fit
Protects against dusts, mists,
fumes, vapors, gases.

7. Air-Purifying Respirators
Cartridges and Filters
Change after each use
Choose the right filter for the job

8. Air-Purifying Respirators
Full Face Respirators

9. Emergency Evacuation Air
Emergency Escape Breathing Apparatus
Provides 5 minutes (42 Ipm high-volume air flow) for quick escape.
Includes plastic hood w/deflector to minimize fogging.
Refillable lightweight aluminum air cylinder.
Harness for wear on shoulder, neck, or waist.
NIOSH/MSHA approved for respiratory protection from:
» deficient atmospheres,
» gases
» vapors
At temperatures above 0˚ F (-18˚ C).

10. Particulate Respirator Selection
NIOSH 42 CFR 84 Regulations
Regulation provides nine filter types
3 levels of filter efficiency:
» 95% (called “95”)
» 99% (called “99”)
» 99.97% (called “100”)
3 categories of resistance to filter efficiency degradation:
» N (Not resistant to oil)
» R (Resistant to oil)
» P ( oil Proof)

11. Selection of N,R, and P-series filters
If no oil particles are present, use a filter of any series.
If oil particles are present, use an R- or P-series filter.
If oil particles are present and the filter is to be used for more than one work shift, use only a P-series filter.
Selection of filter efficiency depends on how much filter leakage can be accepted.
Choice of face piece depends on level of protection needed – the assigned protection factor (APF).

12. Definitions High Efficiency Particulate Air Filter (HEPA)
» A filter that is at least 99.97%
efficient in removing
particles of 0.3
micrometers in
diameter.

13. Immediately Dangerous to Life and Health (IDLH):
Definitions
Immediately Dangerous to Life and Health (IDLH):
- An atmosphere that poses a threat to life, would cause irreversible health effects, or would impair an individuals ability to escape from a dangerous atmosphere
an atmosphere that poses a threat to life,would cause irreversible adverse health effects, or would impair an individual’s ability to escape from a dangerous atmosphere.

14. Oxygen Deficient Atmosphere
Definitions
Oxygen Deficient Atmosphere
- An atmosphere with an oxygen content below 19.5% by volume.
An atmosphere with an oxygen content below 19.5% by volume.

15. Why are respirators necessary?
1. Because industrial hygiene monitoring has been done and the levels of chemicals in the air are above what you can be exposed to over an 8 hour work day.

16. Why are respirators necessary?
2. Could mean that engineering controls can not be put into place.

17. Medical Evaluation
Is done by a physician or other licensed health care professional (PLHCP) to determine of employee is medically able to use respiratory protective equipment.
A medical questionnaire is administered confidentially during normal working hours. It provides description for review and any required medical follow-up examinations.
See Appendix F for sample Form

18. Fit Testing Qualitative Fit Tests
- The worker is exposed to Banana Oil and then asked to: breath deeply, move head side to side, move head up and down, and talk. The worker reports any noticeable odor that is leaking into the mask.
- Banana Oil Test:
This chemical has a pleasant, easily detectable odor, which is used to check the face piece seal when organic vapor cartridges are used. If odor is detected this indicates the fit is faulty and adjustment is required.

19. Positive Pressure Fit Check
1. Block the exhalation valve with the palm of the hand.
2. Gently exhale and hold for about 10 seconds.
3. Check to see if the face piece is bulging slightly.
4. If the face piece remains bulging
and there are no air leaks between
your face and the face piece, your
respirator fits properly. If you do
detect leaks, readjust the straps and
check again for a proper fit.

20. Negative Pressure Fit Check
Block the cartridges/filters with the palms of your hand.
Gently inhale and hold for about 10 seconds.
Check to see if the face piece is collapsing slightly.
If the face piece remains collapsed
and there are no air leaks between
the face and face piece, you have a
properly fitting respirator. If you
detect leaks, readjust the straps
and check again for a proper fit.

21. Improper fit, use and maintenance
If a respirator is worn improperly, it can be more of hazard than not wearing one at all
An improper fit means you could be exposing yourself to a deadly material and still feel protected, when you are really not protected at all
It is important to find a respirator that perfectly fits your face
It is important to check your respirator before EACH use for cracks or broken seals

22. Limitations and Capabilities
A respirator can ONLY be used when the oxygen level in the atmosphere is between 19.5% and 21%
Respirators will only work with corresponding filters or cartridges
Dusty area = HEPA filter
Dumping solvents, painting = organic vapor cartridge

23. Signs or Symptoms that could prevent use
Broken Ribs
Chest Injuries/Surgeries
Any other lung problems
Heart or Circulation problems
Anxiety
Seizures
Claustrophobia
Asthma
Emphysema
Pneumonia
Collapsed Lung
Lung Cancer

24. Inspection of Respirators
Respirators should be inspected before each use
Check the respirator function, tightness of connections and the condition of various parts such as the face piece, head straps, valves and cartridges
Check elastic parts for pliability and signs of deterioration

25. Cleaning and Disinfecting
Remove filters, cartridges or canisters. Discard or repair any defective parts
Wash components in warm water with a mild detergent or cleaner; use a brush with bristles NOT wire
Rinse components thoroughly in clean warm running water

26. Cleaning and Disinfecting
4. Hand dry components with clean lint free cloth or air dry
Reassemble face piece, replacing filters, cartridges and canisters where necessary
Test respirator to ensure all components work properly

27. Storage
All respirators shall be stored to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture and damaging chemicals.
They shall be packed and stored to prevent deformation of the face piece and exhalation valve
