1 Powered Air Purifying Respirator (PAPR) For Departments that Store, Supply and Maintain PAPR Units

2 Warning: Read the printed User Instructions provided with each PAPR system before use. The User Instructions include numerous warnings that, if not followed, could result in serious injury, sickness or death. OHSU s Respiratory Protection Program (as required by OSHA 29 CFR ) can be found on-line, in the Infection Control manual. Medical Evaluation Form must be completed prior to an employees use of a PAPR.

3 Head Cover/Hood PAPR Components Breathing Tube Blower / Filtration Unit (w/airflow Indicator) Head Cover Head Cover Battery Charger

4 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 aerosols PAPR with head cover reduces exposure by a factor of 25. HEPA filters do not reduce exposure to gases or vapors Must not be used in an oxygen deficient environment

5 PAPRs at OHSU The Equipment Pool (EP) will be responsible to distribute PAPRs to patient care units who order them to use for patients in Strict Isolation or Airborne Precautions for TB or R/O TB. When PAPRs are ordered, the EP will send 3 PAPR units with attached hoods (2 small, 1 large) to the units. All PAPR units need to have their airflow checked with the airflow indicators before they are sent to the unit(s) for use. Airflow indicators need to be supplied by the department. Daily, when making rounds, the EP will replace the used PAPR units with freshly charged units that have had their airflow checked. Unused PAPRs will remain in their sealed bags. Disinfect and recharge used PAPR units when they are returned to the EP. PAPR hoods are available from Logistics. Each nursing unit will need to stock some additional hoods. However, the initial PAPR units with attached hoods will still need to be supplied by the EP.

6 Before Sending to Unit: 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. Additional airflow indicators and tubing should be ordered and stored in the EP.

7 Before Sending to Unit: 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.

8 Before Sending to Unit: Head Cover or Hood Inspect the head cover or hood for damage (cracks, tears). 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. Secure the unit and belt to your waist. To use, turn on the power switch on the battery pack. Note: Head cover cannot be worn with facial hair that interferes with the seal to the face.

9 Before Sending to Unit: Battery Charging There are three battery chargers available: Single Battery Charger Unit Charger Unit Charger

10 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. Green LED light

11 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 it is best to disconnect after fully charged.

12 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.

13 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 facility s infection control practices.

14 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 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.

15 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.

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 Sanimaster 4 or SaniCloth. 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 Sanimaster 4 solution or SaniCloth.

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. PAPRs assigned to an individual should be marked as such or stored in a specific location.

18 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. Batteries must be charged weekly for 1 hour or overnight. 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 Problem Smell or taste contaminants, irritation during use Blower does not run when switch depressed Low airflow Possible Causes Misuse, improper assembly, or malfunction of equipment Battery is discharged Faulty power switch Faulty motor Battery needs charging Filter is loaded PAPR blower malfunction Breathing tube restricted. Corrective Action Leave work area immediately and contact supervisor. Do not use PAPR until corrected. Recharge or replace battery Replace motor blower Replace motor blower Switch to fully charged battery Replace filter Switch to a different blower unit Remove restriction
