Intended Use

• Motor blower draws contaminated air through a
  high efficiency particle (HEPA) filter and blows
  filtered air up into head covering
• When properly used, helps reduce respiratory
  exposure to airborne particles such as dust,
  mist, biological and radiological aerosols

• PAPR with head cover reduces exposure by factor
  of 25, PAPR with hood reduces exposure by factor
  of 1000
• HEPA filters do not reduce exposure to gases or
  vapors
• Do not use in oxygen deficient environments

5
Before Use Breathing Tube

• Inspect the breathing tube and body of the blower
  / filtration unit for punctures, cracks or
  general wear.
• Insert the breathing tube (male end with pin)
  into the blower / filtration unit and twist
  clockwise to lock in place.

6
Before Use Check Flow

• Hold the free end of the breathing tube up by
  grasping the slotted connector and covering the
  slots of the connector with thumb and forefinger.
• Drop the black, bullet-shaped airflow indicator
  (pointed end first) into the slotted connector
• Switch the filter unit on. Hold the tube so that
  it is vertical and at eye level.
• If the lower band on the indicator rises above
  the slotted connector edge, airflow is
  sufficient. If not, check the breathing tube,
  battery and filter.

7
Before Use Head Cover or Hood

• Inspect the head cover or hood for damage.
• Push the slotted end of the breathing tube into
  the connector in the rear of the head cover or
  hood until it snaps into place.
• Pull the head cover or hood over your head and
  adjust it so the headband wraps around your head.
• Pull the elasticized edge of the faceseal under
  your chin.
• For the hood, tuck the inner shroud under your
  protective clothing and allow the outer shroud to
  hang outside your clothing.

Note Head cover cannot be worn with facial hair
that interferes with the seal to the face. Hoods
may be worn with facial hair.

Before Use Battery Charging

• There are three battery chargers available

9
Battery Charging (Cont.)

• Place the charger in a cool environment--less
  than 77F (25C). At higher temperatures, the
  battery pack may not accept a full charge.
• If a battery pack feels hot, let it cool for 1/2
  hour before charging.
• Do not charge multiple battery packs in a closed
  cabinet without ventilation.
• Plug the power cord into a regulated 120V-60Hz
  outlet. The green LED light will turn on.

10
Battery Charging (Cont.)

• Insert the charging lead into the socket in the
  side of the blower/filtration unit.
• The LED will turn off, indicating that the
  battery pack attached is being charged in a high
  rate mode. A completely exhausted battery pack
  should be charged for about 8 hours.

LED turns off when battery is charging.

• When the battery is finished charging, the LED
  will turn back on. The charger will also switch
  to trickle rate mode, preventing damage to the
  battery from overcharge.
• Batteries may be left on trickle mode to maintain
  optimum capacity for up to 30 days, but best to
  disconnect after fully charged.

11
Battery Charging (Cont.)

• Batteries provide up to 500 charge/discharge
  cycles when not exposed to high heat for extended
  periods of time.
• Charge battery packs before they are completely
  discharged. Damage may occur if the battery pack
  is completely discharged ("deep discharged")
  frequently.
• A NiCad battery stored at room temperature loses
  approximately 1 of its charge each day.
  Self-discharge during storage will not damage the
  battery.
• Batteries subjected to prolonged storage (longer
  than 6 months) may lose their capacity to hold a
  full charge.
• See also Suggested Monthly Maintenance slide

Filter Replacement

• The high efficiency filter must be changed when
• The unit does not pass the air flow test with a
  properly charged battery.
• If the filter has been physically damaged.
• According to local administrative procedures.

Note In a relatively clean environment such as
healthcare, it may take a long time before the
filter becomes clogged to the point of
significantly reducing airflow. Also, filtration
efficiency may increase as the filter becomes
loaded. In their 1994 TB guidelines, CDC stated
that it would be unlikely for particles captured
in a filter to be reaerosolized. However,
certain pathogens may be transmitted via physical
contact with the outside of the filter.
Therefore, filter replacement must also be in
accordance with your facilitys infection control
practices.
13
Filter Replacement (cont.)

• Pull the belt away from the back cover. Release
  the locking tab and remove the back cover.
• Remove and discard the filter and gasket in
  accordance with local, state and federal
  guidelines.
• Do not attempt to clean the filter.

gasket
Note Appropriate personal protective equipment
should be worn depending on the substance
collected on the filter. Certain substances are
hazardous through physical contact and others are
not.
14
Filter Replacement (cont.)

• Inspect the new gasket to ensure it is free from
  damage. Insert the filter gasket into the filter
  support ridge so that it is flush with the sides
  of the unit, leaving no gaps.

• Put the filter into the unit with the arrows on
  the filter pointing into the unit.
• Snap the cover with locking tabs. Pull the belt
  through the belt retainers.

15
Cleaning

• Follow the industrial hygiene / infection control
  practices established by your employer for the
  specific contaminants to which you have been
  exposed.
• Wipe the outside surfaces of the PAPR system with
  a mild solution of warm water and mild detergent.
  Do not clean with organic solvents. Do not soak
  the blower unit or battery in cleaning solutions.
• Wipe with a cloth dampened with clean warm water.
• If necessary wipe with a cloth dampened with a
  hypo chlorite solution (1 oz. 30ml household
  bleach in 2 gallons 7.5 L of water).
• Other methods of cleaning, disinfection or
  sterilization have not been tested for
  compatibility with the PAPR, may damage the PAPR
  system, and therefore must not be used.

16
Storage

• Store components in a cool dry area that is free
  from contaminants and direct sunlight.
• Store in such a way as to protect the PAPR from
  physical damage.
• Respirators assigned to an individual should be
  marked as such or stored in a specific location.

17
Suggested Monthly Maintenance

• According to OSHA, respirators used for
  emergencies must be inspected monthly and before
  and after use.
• Visually inspect the entire PAPR system (blower,
  breathing tube and hood or head cover) and
  perform a flow check.
• If flow is not adequate, inspect and/or replace
  filter, battery or charger as necessary.
• Charge the battery for 8 hours and store unit.
• Note depending on the required use time, may
  need to repeat charging cycle more often than
  monthly to compensate for self discharge.
• Periodically (e.g. every 6 or 12 months), run the
  PAPR for 8 hours and check each hour for adequate
  flow.
• If flow is not adequate, several charge/run-down
  cycles may restore battery capacity. If flow is
  still not adequate, replace filter, battery
  and/or charger.

Frequently Asked Questions

• Q Does the PAPR protect against inhalation of
  biological agents?
• A Living organisms are filtered with the same
  efficiency as non-living particles of the same
  aerodynamic diameter.
• Respirators only reduce exposure. They do not
  eliminate exposure. Since everyone has a
  different immune system, we can not say that a
  respirator will prevent disease. It only reduces
  exposure. There are no recognized safe levels
  or occupational exposure limits for biological
  agents.

19
Frequently Asked Questions

• Q Are small particles such as viruses filtered?
• A Smaller isnt necessarily more difficult to
  filter. Filters are tested against particles
  that are roughly the most difficult size to
  filter, about 0.3 µm. The HEPA filter has
  filtration efficiency greater than 99.97 against
  this sized particle. Smaller or larger particles
  are easier to filter. For example, below 0.1 µm,
  diffusion becomes a very effective capture
  mechanism. If viruses are aerosolized, they are
  usually contained in a droplet so the aerodynamic
  diameter is larger than the size of the virus by
  itself.

20
Frequently Asked Questions

• Q Do I need to decontaminate the PAPR or discard
  it after use?
• A It all depends on what it was exposed to. CDC
  stated that m. Tuberculosis needs to be
  aerosolized to contract TB. Therefore,
  extraordinary cleaning of surfaces was not deemed
  necessary. However, CDC stated that surfaces
  directly contaminated during care of a SARS
  patient should be cleaned with a U.S.
  Environmental Protection Agency (EPA)-registered
  disinfectant. Check with your infection control
  regarding the precautions required for the agent
  or pathogen in question.

21
Frequently Asked Questions

• Q Why would I use a PAPR instead of a N95
  filtering facepiece?
• A Half masks (covering the mouth and nose)
  reduce exposure by a factor of 10 when properly
  fitted and worn. CDC has identified certain high
  risk procedures (e.g. sputum induction) where a
  more protective respirator should be considered.
  PAPRs with head covers and hoods do not need to
  be fit tested. Negative pressure respirators
  require the wearer to draw air through a filter
  during inhalation. PAPRs are often more
  comfortable as filtered air is blown up to the
  hood or headcover and there is no increased
  breathing resistance.
