4. 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 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

5. 520-01-61 10 Unit Charger 520-03-72 5 Unit Charger 520-03-73 Single Battery Charger Before Use: Battery Charging • There are three battery chargers available:

6. Green LED light Battery Charging (Cont.) • Place the charger in a cool environment--less than 77°F (25°C). 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.

7. 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 to prolong the life of the battery.

8. 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. This may be corrected by cycling the battery through several charge/discharge cycles. • See also “Suggested Monthly Maintenance” slide

9. . Filter Replacement The HEPA filter must be changed when: • The filter has been physically damaged • The unit does not pass the air flow test with a properly charged battery. • 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. • According to local administrative procedures. • In their 1994 TB guidelines, CDC stated that it would be unlikely for particles captured in a filter to be reaerosolized. However, filter replacement must also be in accordance with your facility’s infection control practices.

10. 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. gasket Do not attempt to clean or reuse the filter. 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.

11. 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.

12. Before Use: Inspection • Ensure that HEPA filter and gasket have been properly installed • Check breathing tube for any punctures • Check body of the blower / filtration unit for cracks or general wear. • Inspect the head cover or hood for damage.

13. Before Use: Flow Check • Insert the breathing tube (male end with pin) into the blower / filtration unit and twist clockwise to lock in place. • 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. Repeat Test.

14. Attach the unit to your waist and turn it on 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. Donning Note: Head cover cannot be worn with facial hair that interferes with the seal to the face. Hoods may be worn with facial hair.

15. Trouble Shooting

16. 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 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 hypochlorite 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.

17. 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.

18. 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: NiCd batteries self discharge about 1% per day at room temperature.Depending on the required use time, may need to charge the battery more often than once per month. • 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.

19. Q: Does the PAPR protect against inhalation of biological agents? Frequently Asked Questions

20. Q: Does the PAPR protect against inhalation of biological agents? Living organisms filtered same as non-living particles of the same aerodynamic diameter No recognized “safe levels” or occupational exposure limits for biological agents Everyone has a different immune system Respirators reduce, not eliminate, exposure Frequently Asked Questions

21. Q: Are small particles such as viruses filtered? Frequently Asked Questions

23. Q: Are small particles such as viruses filtered? Smaller isn’t necessarily more difficult to filter Filters tested against particles that are roughly the most difficult size to filter, about 0.3 μm HEPA filter has filtration efficiency greater than 99.97% against this sized particle. Smaller or larger particles are easier to filter Aerosolized viruses are usually contained in a droplet with aerodynamic diameter larger than virus by itself Frequently Asked Questions

24. Q: Do I need to decontaminate the PAPR or discard it after use? Frequently Asked Questions

25. Q: Do I need to decontaminate the PAPR or discard it after use? CDC stated m. Tuberculosis needs to be aerosolized to contract TB. Extraordinary cleaning of surfaces not deemed necessary CDC stated surfaces directly contaminated during care of a SARS patient must be cleaned with a U.S. Environmental Protection Agency (EPA)-registered disinfectant Check with your infection control department regarding the agent or pathogen in question Frequently Asked Questions

26. Q: Why would I use a PAPR instead of a N95 filtering facepiece? Frequently Asked Questions

27. Q: Why would I use a PAPR instead of a N95 filtering facepiece? Negative pressure half mask respirators (covering the mouth and nose) reduce exposure by a factor of 10 when properly fitted and worn. Certain high risk procedures (e.g. sputum induction on a suspect TB patient) may require a more protective respirator such as a PAPR PAPRs with head covers and hoods do not need to be fit tested; hoods can be worn with facial hair PAPRs are often more comfortable as filtered air is blown up to the wearer instead of having to physically draw air through a cartridge or filter Frequently Asked Questions
