When used, FitPlus software controls all P functions making it unnecessary to use the keypad controls ORTA...

  • Page 21: Fit Testing Without Computer Software

    Fit Testing Without Computer Software Follow the steps below to setup the P Plus for fit testing in “stand-alone” mode instead of ORTA OUNT using FitPlus Fit Test Software. In stand-alone mode, you will have to manually record the fit test results and information about the person and respirator being fit tested.

  • Page 22: Conducting A Fit Test In Stand-Alone Mode

    Conducting a Fit Test in Stand-alone Mode The instructions below assume that you want to perform a fit test using a half-mask respirator in compliance with the US Dept. of Labor, Occupational Safety and Health Administration (OSHA) Respiratory Protection Standard 29 CFR 1910.134. Make appropriate adjustments for other fit test protocols.
  • Page 23 previous exercise will remain visible on the display along with the PASS or FAIL message. As originally shipped, the P Plus will use 60-second exercises to comply with U.S. ORTA OUNT OSHA Standard 29CFR1910.134. Normal breathing Remain still and breathe as usual. Deep breathing Take long deep breaths as if working hard.

  • Page 24: Common Problems Resulting In Low Fit Factors

    Common Problems Resulting in Low Fit Factors Here is a list of the most common problems that result in lower than expected fit factors. Assuming the Plus passes the Daily Checks, explore the following possibilities. ORTA OUNT Not using high efficiency filters If you are not using high-efficiency class-99 or class-100 filters (P3 for non-USA users) on the respirator, you may never get a high fit factor.

  • Page 25: Operating The Portacount Plus

    Chapter 4 OPERATING THE PORTACOUNT PLUS This chapter contains detailed instructions for operating the P ® Plus Respirator Fit Tester ORTA OUNT manually as a stand-alone instrument. You should learn to operate the P Plus in this manner ORTA OUNT even if you plan to use the IBM-PC compatible FitPlus Fit Test Software included with the instrument.
  • Page 26 Locate a fully charged battery pack and plug it into the battery connector located inside the battery compartment. Note that the two connector pins are different sizes. Make certain that the connector is inserted into the battery pack with the correct polarity. DO NOT force the connector into the battery pack.

  • Page 27: Connecting The Optional Printer

    Connecting the Optional Printer The P Plus can be used with an optional portable printer. The printer provides hard copy ORTA OUNT documentation of the fit test and eliminates the tedious and error-prone task of manually recording fit test results. Of course, if you want the ultimate degree of automation, you should use the FitPlus Fit Test Software included with your P Plus.

  • Page 28: Fit Test Mode

    If a printer is used, the data printed in 1-Second Count Mode is actually 2-second averages, printed every 2 seconds (because the printer is too slow to print every second). The Display shows 1-second averages, updated every second. In 15-Second Count Mode, both the Display and printer will show 15-second averages, printed and updated every 15 seconds.
  • Page 29 displayed. The fit factor for the final exercise will be displayed for only 3 seconds. Then a triple "beep" will sound, indicating that the fit test has been completed and the overall fit factor and PASS/FAIL message is visible on the display. If the fit test is terminated before the last exercise is completed (by pressing the TEST START/STOP key), the fit factor display will go blank and the exercise number will reset to zero.

  • Page 30: External Control Mode

    question arises as to whether or not the P Plus is functioning properly. See the ORTA OUNT maintenance chapter for instructions on performing the Daily Checks. External Control Mode External Control Mode is used when the P Plus is being controlled through the Data ORTA OUNT Port by an external computer.

  • Page 36 The isopropyl alcohol that is required to properly operate the P Plus must be very high purity ORTA OUNT "reagent grade" (99.5% pure) alcohol. Isopropyl alcohol that is available from pharmacies, drug stores, or other consumer outlets is low purity and usually contains significant percentages of water and other substances that can cause performance problems with the P Plus.
  • Page 37 Fill Line Squeeze alcohol into the Alcohol Fill Capsule until it is even with or slightly above the scribed fill-line near the base. RECAP THE ALCOHOL BOTTLE IMMEDIATELY. NOTE: TSI used to provide a black sponge located at the bottom of the Fill Capsule. That sponge is no longer used and should be removed from the Fill Capsule.

  • Page 38: Alcohol Cartridge

    ALWAYS RECAP ALCOHOL FILL CAPSULE AND OTHER CONTAINERS IMMEDIATELY TO PREVENT ABSORPTION OF MOISTURE AND THE ESCAPE OF ALCOHOL VAPORS. If you do not intend to use the P Plus right now, you should store the Alcohol ORTA OUNT Cartridge in the Alcohol Fill Capsule. The Alcohol Fill Capsule is designed to be a safe transportation and storage container for alcohol.

  • Page 39: Changing The Alcohol Wick

    ALCOHOL CARTRIDGE CLEAN. ALWAYS SET THEM DOWN WITH THE END STANDING UP. Changing the Alcohol Wick The wick and screen inside the Alcohol Cartridge may be changed in the field. Two spare wicks and screens were included with the P Plus when it was new.

  • Page 40: Re-Assembling The Alcohol Cartridge

    Hold the screen up to the light and look through it to make sure it is clean. All openings in the mesh should be clear. If any of the openings are blocked, clear them by blowing air through the screen. If the screen cannot be 100% cleaned, replace it with a new one. A new screen is included with each new wick.

  • Page 41: Daily Checks

    Daily Checks There are three maintenance checks that should be performed once each day the P Plus is used ORTA OUNT and whenever a problem is encountered. The Daily Checks must be performed in the order given below. 1. Particle Check 2.

  • Page 42: Max Ff Check

    If the P Plus will not Zero Check, any fit tests you conduct may result in lower fit ORTA OUNT factors than would be measured otherwise. The risk is that you may fail people who actually have good fits, thereby wasting time and effort. There is no possibility that failure to Zero Check could result in overstated fit factors.

  • Page 43: Battery Maintenance

    TSI recommends that the Zero Check Filter be left attached to the sample line whenever the Plus is turned on but not in use. This prevents lint and debris from being drawn into ORTA OUNT the instrument and blocking the air flow. Battery Maintenance NOTE: As of January 2003, battery packs are no longer available from TSI.

  • Page 53: Theory Of Operation

    Appendix B THEORY OF OPERATION How the P Plus Works ORTA OUNT The P Plus measures respirator fit by comparing the concentration of microscopic particles ORTA OUNT outside the respirator to the concentration of particles that have leaked into the respirator. The ratio of these two concentrations is called a fit factor.
  • Page 54 Aerosol is drawn through the instrument by a diaphragm vacuum pump operating at a flowrate of 0.7 liter per minute. The flow enters the instrument through either the ambient port or the sample port. The switching valve determines which port is used. The outlet of the switching valve leads to the saturator end cap where the flow splits.

  • Page 55: Calculating Fit Factor

    Appendix C CALCULATING FIT FACTOR Fit factor is defined as the particle concentration outside the respirator divided by the particle concentration inside the respirator. Because ambient concentration can vary over time, the P Plus calculates the fit factor by ORTA OUNT taking the average of the ambient concentrations measured before and after the respirator sample and then dividing by the concentration measured in the respirator.

  • Page 57: Calculating Particle Concentration

    Appendix D CALCULATING PARTICLE CONCENTRATION Particle concentration is calculated by counting the number of particles passing through the sensor in a given period of time. Since the flow rate is known (1.67 cm /sec), the particle concentration can be determined. In 1-Second Count Mode the equation is: Particle Concentrat...

  • Page 61: Using The Tsi Porta Ount Plus To Fit Test Positive Pressure Respirators

    Appendix F USING THE TSI P PLUS TO FIT TEST POSITIVE ORTA OUNT PRESSURE RESPIRATORS On January 8, 1998, OSHA released the long-awaited revision to the Respiratory Protection Standard 29CFR1910.134. It replaces the standard with the same name and number that was released in 1971. This new revision has far reaching impact on a large number of existing OSHA standards in that it replaces certain provisions related to respirator use.
  • Page 62 When an adapter is not available, the only alternative is to use a surrogate mask or test mask. This involves purchasing a negative-pressure air-purifying mask that has the same sealing surfaces as the positive- pressure mask that will actually be used for respiratory protection. For quantitative fit testing, the mask will need a sampling port so that a sample can be drawn from the breathing zone.
