1.6 WARNINGS

1. The TDA-99M is a heavy item when packed in its case. ALWAYS follow proper procedures when lifting a packed case; use two people to lift or carry. NEVER try lifting the packed case over your head. NEVER drop it into place—lower it carefully. 2. DO NOT ingest PAO oil. Refer to the Material Safety Data Sheet in Appendix E. 3. NEVER place the pressure and vacuum lines near your face. 4. To avoid eye injury, use care when handling the fit test support rods. 5. DO NOT connect the power cord if any wiring is frayed. 6. Isopropyl alcohol should be used only in accordance with supplier’s recommendation.

1.7 CAUTIONS

1. PAO is the only authorized challenge oil that should be used with the TDA-99M. Use of other liquids or challenge agents may damage or contaminate the internal optics of the light scattering chamber. 2. To avoid damage, when components are not being used, they should be stored in the plastic tray and/or case. 3. Failure to remove the power unit from the tray before lifting the tray from the case may result in damage to the tray.



1-4

4. PAO oil level must be between the top and bottom scribed fill lines on the aerosol generator bottle for the generator to work properly. 6. DO NOT cross-thread the generator cap to the bottle. Once assembled, the generator bottle should always be attached to the control unit. Damage to the generator cap or control unit may result if the generator bottle is not attached.

7. Failure to ensure the generator port snap tabs are depressed prior to inserting the aerosol generator assembly may cause damage to the control unit and/or aerosol generator assembly. 8. NEVER position the power unit upside down or with the fan opening obstructed. 9. Ensure that the power cable is unplugged during setup and prior to initialization to prevent damage to the TDA-99M. 10. During setup and prior to initialization, ensure that power switch is off to prevent damage to the TDA-99M. 11. NEVER unplug the power interface cable prior to switching the power unit OFF. This action may corrupt the random access memory (RAM) within the control unit. 12. The fit test shroud and fit test interface tubing are easily damaged and should only be assembled prior to performing the fit tests. 13. Do not use a wrench when tightening the canister port plug. Damage may occur to the mask if the plug is over tightened. 14. NEVER plug or block the probe end (blue) of the aerosol probe hose while the aerosol generator is bubbling. Blocking the flow of aerosol may result in damage to internal components of the system. 15. Failure to remove the aerosol generator assembly from the control unit before packing may result in damage to the control unit and/or aerosol generator assembly. 16. Failure to disassemble the generator assembly prior to packing may result in oil spilling during shipping and damage the control and power units. 17. Do not attach the ends of the aerosol probe together during packing. Doing so may cause damage to the open end of the hose. 18. Failure to place the power unit upside down when packed may cause damage to the power interface cable and pressure/vacuum ports. 19. Ensure that no liquid is introduced to the inside of the TDA-99M as this may cause damage to the electronics. 20. Incorrect adjustment of the mask clips may cause disfiguring of or damage to the mask or insufficient sealing, leading to test failures.

1.9 TESTS PERFORMED BY THE TDA-99M

The following tests are performed by the TDA-99M.

1.9.1 MASK LEAKAGE TEST [MASK]

This mode tests a variety of protective masks for leakage. Masks may be tested with or without an attached hose. When a failure is detected the system provides the operator with a probe option to help isolate the location of the leak(s). In the probe mode, aerosol is directed at various areas of the mask to identify which area or component of the mask is leaking. For more information refer to Chapter, Mask Testing.C

1.9.2 DRINK TUBE FLOW TEST [DRINKTUBE/TURN IN]

This mode tests for any airflow obstruction via resistance through the mask drink tube. Connecting the mask drink tube to the drink tube test adapter on the control unit pedestal opens the quick-disconnect valve to allow airflow. The resistance is measured as the airflow is passed through the drink tube. For more information refer to Section 6.1, Drink Tube Flow Test [DRINKTUBE/TURN IN].

1.9.3 DRINK TRAIN ASSEMBLY LEAKAGE TEST

This mode tests the airflow leakage through the entire mask drinking assembly. Prior to initiating this test, the internal drink tube must be plugged. For more information refer to Section 6.2, Drink Train Assembly Leakage Test.

1.9.4 DRINK VALVE SEAT TEST [DRINKTUBE/TURN OUT]

This mode identifies leakage in the drink tube’s quick disconnect coupling valve. Once the mask’s drink tube is connected to the drink tube test adapter on the control unit pedestal, airflow leakage from the applied air pressure is measured. For more information refer to Section 6.3, Drink Valve Seat Test [DRINKTUBE/TURN OUT].

1.9.5 OUTLET VALVE TEST [VALVE]

This mode checks the leakage from the outlet valve on the mask. Air pressure is applied against the outlet valve and the airflow is checked. For more information refer to Chapter 7, Outlet Valve Test.



1-6

1.9.6 QUANTITATIVE FIT TEST [FIT]

This mode tests a mask for leakage when worn by an individual. While the subject is wearing the test mask, a shroud is placed over the head and on the individual's shoulders. For this test, aerosol is loaded inside the shroud. The amount of aerosol that breaches the seal of the mask is calculated and displayed as quantitative fit factor, along with a [PASSED] or [FAILED] message. For more information refer to Chapter 8, Quantitative Fit Test.

1.9.7 MASK ALL TEST [M ALL]

This mode tests all functions of the mask and includes the mask leakage test, drink tube flow test, drink train assembly leakage test, drink valve seat test, and outlet valve test, sequentially.

1.9.8 ALL TEST [ALL]

This mode tests the functionality and fit of the mask in succession. It includes the mask leakage test, drink tube flow test, drink train assembly leakage test, drink valve seat test, outlet valve test, and quantitative fit test, sequentially.

3.4.3 ATTACHING THE HEADFORM

NOTE

When initialized, the TDA-99M conducts an inflation and seal test on the headform that is in place. If there is a failure, a SEAL FAILED error message will appear. Refer to Section 12.3.6, Seal Failure, for troubleshooting. If

the headform is changed during operation, the TDA-99M must be restarted to allow the

system to verify the inflation and seal process of the second headform. This seal check is

only required once per headform per operating period.

It is recommended that the SMALL headform be utilized for all mask leakage testing unless the test operator cannot obtain a seal against

the mask. The MEDIUM headform may be used at the test operator’s discretion if a seal can not be obtained with the SMALL headform.

1. Center the headform to be used over the pedestal with the chin (narrow portion) toward the front of the TDA-99M.

5 Mask Testing A mask test allows the operator to test the serviceability of the face blank. This test is completed under negative pressure by challenging the mask with an aerosol mist.

5.1 MASK AEROSOL SETUP

An aerosol setup is used to set the 0% aerosol level (best seal) and 100% aerosol level (no seal) for any mask leakage or fit test. These levels must be established every time the TDA-99M is setup in the MASK, FIT, M ALL, and ALL modes or if the TDA-99M is switched off and then restarted in one of those modes. It is also recommended that an aerosol setup be conducted whenever mask testing is resumed after the TDA-99M has been sitting idle for more than sixty (60) minutes.

NOTE

Make sure that the aerosol probe hose input grommet of the test shroud is located at the rear of the headform. Improper assembly may cause

the aerosol to be improperly distributed and possibly cause a false test failure.

1. Place the test shroud over the headform. Ensure that the test shroud completely covers the headform and the aerosol probe hose input grommet is located at the rear of the headform. The headform should be exposed to the open air with no mask attached. Blocking the vacuum port of the headform during aerosol setup will result in a LOW AEROSOL ERROR.

Figure 21. Aerosol Setup

8 Quantitative Fit Test This chapter describes the Quantitative Fit Test. This series of tests is designed to give a standard indication of the leakage rate of a mask while it is being worn by a subject.

NOTE

Fit testing must be conducted in accordance with specific NIOSH, industry, military service,

and protective mask technical directives.

Prior to performing a fit test ensure that the TDA-99M has warmed up for a minimum of 20

minutes. If the testing environment is less than 72°F up to 90 minutes may be required for warmup. Insufficient warmup may lead to

FALSE test failures.

An aerosol setup is required prior to performing the first fit test after initialization.

Prior to performing a fit test, ensure that there is a serviceable canister attached to a

serviceable protective mask in accordance with the appropriate mask technical manual.

8.1 FIT TEST AEROSOL SETUP

NOTE

Section 8.2, Prepare the Subject, may be completed simultaneously with Section 8.1, Fit

Test Aerosol Setup.

An aerosol setup is used to set the 0% aerosol level (best seal) and 100% aerosol level (no seal) for any mask leakage or fit test. These levels must be established every time the TDA-99M is setup in the MASK, FIT, M ALL, and ALL modes or if the system is switched off and then restarted in one of those modes. It is also recommended that an aerosol setup be conducted whenever mask testing is resumed after the TDA-99M has been sitting idle for more than sixty (60) minutes.

1. Connect the fit test interface tube to a shoulder strap inside of the fit test shroud using the badge clip, which is included with the sampling tube.

2. Place the drink adapter end of the fit test interface tubing inside the fit test shroud. It may be exposed to open air or attached to a mask’s drink tube.

3. Ensure the fit test shroud is standing upright (Figure 30).

6. Proceed to Section 8.2, Prepare the Subject.

NOTE

Section 8.2, Prepare the Subject, may be completed simultaneously with Section 8.1, Fit

Test Aerosol Setup.

8.2 PREPARE THE SUBJECT

1. Ensure that all protective mask components are attached to the mask. This includes an outlet valve cover, a serviceable filter canister, the second skin, eyelens outserts, etc.

2. Prepare the mask by removing the internal drink tube or by turning the internal drink tube away from the subject's mouth.

3. Instruct the test subject to sit down.

4. Direct the subject to don, clear, and check the seal of the mask in accordance with mask-specific technical procedures.

WARNING

It is critical to ensure that there are no obstructions in the drink tube during the test. An obstructed drink tube may result in FALSE

PASSING scores. A DRINK test (IAW Chapter 6) should be conducted to verify that there are no obstructions in the drink tube flow path prior to

beginning the fit test.

Figure 30. Attaching the Fit Sampling Adapter



8-4

1. Attach the fit sampling adapter (blue adapter on the fit test interface tubing) to the subject’s drink tube. Make sure that the drink tube is inserted fully into the blue adapter.

Figure 31. Attaching the Badge Clip

2. Attach the badge clip to the excess material on the temple strap.

NOTE

Ensure the end of the sampling line is not resting near the mask’s outlet valve.

3. Place the fit test shroud on the subject’s shoulders with the Y-Hose Aerosol Extender in the back.

Figure 32. Fit Test Shroud

4. Adjust the straps of the fit test shroud to ensure that the subject can move his/her head without hitting the fit test shroud’s surface.

5. Ensure that the green nylon apron of the fit test shroud extends below the subject’s shoulders.

8.3 TEST A SUBJECT

1. Advise the subject to relax. Select <F4>CONT. The shroud will then load with aerosol and automatically advance to the first exercise screen when complete. The following screens will be displayed:

…and then…

NOTE

The <F2>ABORT option is available in every step of the fit test process. Selecting

<F2>ABORT at any time during the fit test process will allow the test to immediately be terminated and returns you to the [READY

SUBJECT] screen.

2. Explain to the test subject that there are a total of five (5) exercises: normal breathing, deep breathing, head side to side, head up and down, jaw rotation. Each exercise will be performed for approximately 1 minute, followed by a 40 second evaluation period.

3. Ensure the subject understands each exercise.

NOTE

After each exercise, a fit score will be displayed in the upper right corner of the

screen.

Recording the fit scores may be a requirement, refer to local technical guidance.

A test subject may receive a low fit score for any single exercise and still receive an overall passing fit factor. The overall fit factor reflects a calculation based on all of the test subject’s

individual fit scores and is not an average.

Be sure the test subject does not over-exaggerate each exercise, as this may cause breaking of the seal and cause inaccurate fit

scores.

NOTE

<F2> ABORT Aborts the current test and displays a [CANCEL DURING TEST] screen.

Ensure that the universal hold-down assembly is properly adjusted. There are five hold-down brackets (four side brackets and one top bracket), six mask clips, and two side bracket clamps. Assembly can be adjusted to fit most mask styles.

CAUTION

Incorrect adjustment of the mask clips may cause disfiguring of or damage to the mask or

insufficient sealing, leading to test failures.

NOTE

The brackets may need to be adjusted for each size/type of mask to be tested. Failure to properly

adjust the brackets may cause false readings during a test.

1. Position the mask to be tested on the headform with the chin of the mask pulled down over the peripheral seal. Apply the mask in accordance with instructions detailed in Section 5.2, Applying a Mask, of this manual.



11-10

Figure 46. Universal Hold Down Assembly

2. Mask brackets and mask clips should be adjusted to follow the angle and location of the mask straps. Adjust the mask clip for each strap to be approximately the distance of the width of one mask clip away (≈ ½”) from the mask buckle in the relaxed state.

3. If adjustments are necessary, use the cross tip screwdriver to loosen the mask clip screws and then adjust the clips up or down the bracket. Tighten the mask clip screws with the cross tip screwdriver when finished. Loosen the wing nuts to slide the mask brackets forward or backward then hand-tighten the wing nuts to secure the brackets in place.

2. Remove the test shroud from the headform, and remove the aerosol probe hose from the test shroud.

CAUTION

NEVER plug or block the probe end (blue) of the aerosol probe hose while the aerosol generator is bubbling. Blocking the flow of aerosol may result

in damage to internal components of the TDA-99M.

3. Hold the aerosol probe hose away from the mask and hose until the numbers on the screen appear to stabilize at their lowest reading.

NOTE

When probing a mask, it is recommended that the hand not holding the probe be cupped around the area of the mask being checked. This will prevent

excess aerosol from drifting over the mask, possibly leading to false readings.

APPENDIX F: PRODUCT WARRANTY

Product Warranty Air Techniques International, Division of Hamilton Associates, Inc.

Air Techniques International, (ATI), warrants the equipment purchased hereunder to be free from material defect in materials and workmanship under normal use and service, when used for the purpose for which it is designed, for a period of (1) one year from the date of shipment. The delivery of repair or replacement parts shall not interrupt or prolong the term of the warranty. ATI further warrants that the equipment will substantially perform in accordance with the technical specifications accompanying the formal equipment offer.

ATI, at its option, will either repair or replace any such items ATI finds to be defective within the stated warranty period, FOB ATI’s plant, PROVIDED:

1. That any claim of defect under this warranty is made in writing within thirty (30) days after

discovery thereof and that inspection by ATI, if required, indicates the validity of such claim to ATI’s satisfaction; and

2. That the defect is not the result of damage incurred in shipment to or from our factory; and

3. That the equipment has not been altered in any way whether as to design or use, whether by replacement parts and/or services not supplied or approved by ATI, or otherwise; and

4. That the equipment has not been abused or neglected; and 5. That the user of the equipment has been properly trained and is operating the equipment

in accordance with the support documentation; and 6. That any equipment or accessories furnished but not manufactured by ATI, or not of ATI

design, shall be subject only to such adjustments as ATI may obtain from the supplier thereof; and

7. That the purchaser and user adhere to all maintenance procedures and schedules recommended by ATI in the support documentation

ATI’s obligation under this warranty is limited to the repair or replacement of defective parts with the exception noted above. If the equipment includes a scattering chamber, ATI’s warranty does not extend to contamination of the scattering chamber by foreign material.

At ATI’s option, any defective equipment which fails within the warranty period shall be returned to ATI’s factory for inspection, properly packed with shipping charges prepaid. No equipment shall be returned to ATI without prior issuance of a return authorization by ATI. If ATI determines that the equipment is not defective or that the customer did not perform user-level maintenance as defined in the support documentation, then ATI reserves the right to charge the customer for the unnecessary service work performed.

No warranties, express or implied, other than those specifically set forth herein shall be applicable to any equipment manufactured or furnished by ATI and the foregoing warranty shall constitute the Buyer’s sole right and remedy. This warranty applies to the original purchaser only and is non-transferable. In no event does ATI assume any liability for consequential damages, or for loss, damage or expense directly or indirectly arising from the use of ATI products, or any inability to use them either separately or in combination with other equipment or materials or from any other cause. The liability of



F-2

ATI shall not be responsible for any claim against a customer or user of the equipment by a third party. No action, regardless of form, may be brought against ATI more than one year after the cause of action has accrued. The remedies of the purchaser herein are exclusive.

EXCEPT FOR THE EXPRESS WARRANTY SET FORTH ABOVE, ATI MAKES NO OTHER WARRANTIES WHETHER EXPRESS OR IMPLIED, WITH RESPECT TO THE EQUIPMENT. ATI SHALL DISREGARD AND NOT BE BOUND BY ANY REPRESENTATIONS OR WARRANTIES MADE BY ANY OTHER PERSON, INCLUDING EMPLOYEES, DISTRIBUTORS, RESELLERS, OR DEALERS OF ATI, WHICH ARE INCONSISTENT WITH THE WARRANTY SET FORTH ABOVE.
