• Selection based on hazards involved.
• Operator training for the selection and use of
  NIOSH approved respirators.
• Provide training on proper use, maintenance, and
  storage of respirator equipment.
• Provide a fit testing program for personnel
  wearing respirators.
• Maintain fit testing and training records.
• Regular evaluation of respirator program.

3
OSHAS Policy on Respirator Use

• Where engineering or administrative controls are
  not feasible or insufficient
• During the time when engineering or
  administrative controls are being implemented
• For emergency response situations

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 gt 19.5
• Atmosphere supplying respirators Not utilized
  on this campus
• SCBAs (self-containing breathing apparatus)
• Supplied air respirators (Type C or CE)
• Combinations of SCBAs and SARSs

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
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

14
Definitions

• Oxygen Deficient Atmosphere

- 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
• 5. Reassemble face piece, replacing filters,
  cartridges and canisters where necessary
• 6. 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

28
Recordkeeping

• Training
• Testing
• Medical Evaluation
• Fit Testing
• Inspection
• Program Evaluation
