O v e r v i e w

The TSI Mask Integrity Test Accessory (MITA) works in tandem with the

PortaCount

®

Respirator Fit Tester to test for leaks or other defects in

CBRN gas masks and full-face respirators.

The MITA has been designed for ease-of-use and ease-of-transport. The top half of the carrying case holds the instrument while the bottom half forms the accessory compartment. The updated Headform design includes an enhanced bladder seal system to provide a tight seal for most gas masks and full face respirators of various types and sizes. Masks attach to the Headform using their own head harness for better representative results.

The PortaCount Fit Tester (sold separately) serves as a particle detector for determining the overall integrity of the mask by performing an aerosol leakage test with the MITA accessory. The mask is mounted on the

Headform and tested under conditions of high vacuum and high constant flow. The integrated aerosol wand and generator is used to pinpoint source of leaks so they can be assessed quickly. The operator uses the aerosol wand to direct a stream of concentrated particles at specific locations around the mask. When the particle stream is near the leak, PortaCount Fit

Tester detects the suddenly elevated particle concentration and alerts the operator. The MITA also tests the integrity of the mask exhalation valve and drink tube train (if applicable).

MITA is easy to use and requires minimum operator training. The display on the MITA guides the first time operator through step-by-step prompts.

The display also provides detailed guidance to how to use the various accessories. Experienced operators appreciate the streamlined menu structure. The experienced operator is able to avoid detailed prompts and move through the tests quickly. Experienced operators can test 12 or more good masks per hour. Troubleshooting defective masks is quick and easy using the aerosol wand to pinpoint leaks.

MITA Mask Adapter kits allow you to perform the mask test using a variety of gas masks and full face respirators. MITA Mask Adapter kits for most major brands of CBRN gas masks and full face respirator are available. A complete list of MITA mask test adapter kits is posted on the TSI Web site http://www.tsi.com

4. Connect the power supply barrel connector from the PortaCount Fit

Tester interface cable to the power supply connection on the back of

PortaCount unit.


5. Connect the end of the Twin Tube provided with the MITA, which is evenly cut to the color-coded fittings on the PortaCount Fit Tester.

6. Remove the Alcohol Cartridge from the Alcohol Fill Capsule and gently shake it to allow excess alcohol to drip back into the Capsule. Refer to the PortaCount User

’s Manual for more information on how to properly charge the alcohol cartridge prior to use.

7. Insert the Alcohol Cartridge into the cartridge cavity of the PortaCount

Respirator Fit Tester. It should slide in with little effort. DO NOT

FORCE IT. When almost fully inserted, firmly twist the Alcohol

Cartridge clockwise until it locks into position.


8. Perform a PortaCount Daily Check every day before use, as described in the PortaCount Fit Tester User

’s Manual before using with MITA.

Note

If operating the model 8038 PortaCount Pro+ Respirator Fit Tester, do

NOT select the N95 checkbox when performing the Daily Checks.

9. At the other end of the Twin Tube sample tubing provided with the

MITA, the clear hose is approximately 1 inch longer than the blue hose.

AFTER performing a PortaCount Daily Check, connect the clear hose to the mask sample port at the bottom of the Headform.

Clear Twin Tube sample hose connected to Mask

Sample port

10. If using the 8030 or 8038 models of PortaCount Fit Tester, they must remain on the “Activities” screen. Trying to use the 8030 or 8038 on any ot her screen will cause intermittent “unexpected response” errors on MITA.

Prepare Masks for Test

This menu option provides information on how to prepare the gas masks and full-face respirators for testing. The Mask Test Protocol is selected and

defined in the Settings Menu.

Note

If you have not already performed a Self Check for the day, please complete this process BEFORE testing a mask.

WAIT to install the Mask on the Headform until the Mask Protection

Factor test prompts to install it. The mask is installed ON the Headform

ONLY during the Mask Protection Factor test.

If the mask being tested has a Drink Tube or Exhalation Valve that will be tested, leave the mask OFF the Headform. Both Drink Tube Test and

Exhalation Valve Test are done with the mask OFF the Headform.

1. Before starting, thoroughly inspect the mask to detect any obvious defects.

2. If the inside of the mask is dirty or contaminated, it should be cleaned.


3. Remove the mask filter before conducting the Mask Protection Factor test.

4. Install the appropriate Mask Filter Plug in place of the mask filter removed in the previous step.

When installing the Mask to the Headform:

1. Loosen the mask straps completely so they will go around the back of the Headform

2. Locate the chin cup of the mask on the chin portion of Headform first, and pull the mask straps up and back over the Headform, making sure to keep it snug to the Headform.

3. Make sure the Mask is centered on the Headform Bladder Seal.

4. Snug the straps tight.

5. Recheck to make sure the mask is centered from side to side.

Note

Typically masks seal better to the headform bladder when placed slightly higher up on the headform, so that the upper sealing surface is less than an inch below the top of the headform bladder. This is not applicable to all models and sizes of masks, and experience will help to determine which masks fit best which way. Try adjusting the mask higher or lower on the headform first when experiencing difficulties passing a Protection

Factor test.

TSI recommends performing a Self Check each day before the MITA is used. The purpose of the Self Check is to verify that the MITA is working properly and that mask testing can be performed successfully. The user will be prompted, by the MITA display, for the appropriate connections and/or tasks during each of the Self Check tests.

Note

When the Bladder is being inflated the Aerosol Generator will also run, and aerosol will exit from the Aerosol Mixer.

The results of each Self Check test will be logged. The last Self Check log is then checked for a passing result for the 24 hours prior to running Test

Masks.

If there was a problem with the Self Check within the last 24 hours, or the

Self Check has not been tested within the last 24 hours, a message will be displayed asking the user to run the Self Check or to skip the Self Check. If the last Self Check passed and the instrument is power cycled within the last 24 hours, repeating the Self Check is not prompted, however it may be appropriate to run the Self Check again if the MITA is reset up or in a different location.

Whether the individual tests performed during the Self Check are enabled or disabled is determined by the Define Mask Protocol menu (Settings

4-1

Menu) and the Self Check Parameters menu (Tech Functions). For example, the factory default

Mask Test Protocol is “APR,” which has the separate DT and EV tests disabled. Because these tests are disabled, the

Self Checks will not include additional DT and EV tests.

When the “CBRN”

Mask Test Protocol is selected, the DT and EV tests are enabled. The Self

Checks will then include the DT and EV tests. In the Self Check

Parameters menu the

“Skip Unused Self Check” must also be set to

Enabled.

The numerical value of the test is then compared to the desired pass/fail range for each test, as set in the Self Check Parameters menu, to determine the result of the test.

The default Mask Protocol settings have been defined for general purpose use by TSI. These test settings represent accepted industry standards but are not specific to any regulations.

The default Protection Factor levels were calculated by taking the inmask flow rate of 16 L/min (during the Protection Factor Test) and dividing this value by the acceptable mask leak rate.

For example, if a mask had an acceptable leak rate of 0.5 sccm, then to calculate the Protection Factor needed take 16 L/min and divide by

0.5 sccm, which equals 32,000.

Mask Sample Time Notes

This menu option provides information on how the Mask Sample

Time is calculated and describes the conditions that will effect this value. For more detailed information on this calculation refer to the text found under this menu option on the MITA unit.

The Mask Sample Time, is the time in which a sample is taken from inside the mask during the Mask Protection Factor Test, the length of time is calculated from:

 The required mask protection factor. (PF)

 Ambient aerosol concentration.

 The required accuracy of the mask sample (CV).

Note



A higher PF setting may cause the Mask Sample Time to be extended, and the overall test process may take longer.



A lower CV setting (more accuracy) may cause the test to be longer



A higher aerosol concentration allows the test to be shorter.



Upload Mask Protocols

This function allows the user to upload a Test Mask Protocol, which was created via the MITA menu interface, to a PC with the MITA Communicator

Software installed, where it can then be saved to the PC’s memory. Note, this function does require the MITA to be connected to a PC.

Refer to Chapter 8, MITA Communicator Software for more information on

this function.

The password required to access this option is “MITACOM”. Enter the password, and then press SAVE & EXIT.

Aerosol Generator Settings

Select this option to set the operating parameters of the Aerosol Generator.

The Aerosol Generator is used to generate aerosol during the Self Check,

Test Masks and Find Mask Leak procedures. The Aerosol Generator

Pump Voltage is the voltage setting of the pump that supplies compressed air to the aerosol generator. Pump voltage directly relates to aerosol concentration produced, and increase in voltage will increase the aerosol concentration. This menu also allows the operator to set two different

Aerosol Generator Pump Voltage values:

1. Aero Gen Pump V: Purge

2. Aero Gen Pump V: Test

The purpose of these two voltage settings is to stabilize the aerosol concentration during the Mask Test. It is very desirable that the aerosol concentration measured at the beginning of the Protection Factor test and at the end of the Protection Factor test are similar. This is achieved by setting the “Aero Gen Pump V: Test” slightly (about 1.25 volts) lower than the

“Aero Gen Pump V: Purge” voltage.

The recommended ambient aerosol range during operation is

100,000 pt/cc to 300,000 pt/cc.

These voltage values may need to be adjusted depending on the ambient temperatures, especially in colder environments. Use the real-time particle concentrations displayed on the screen to determine which voltage settings are best for each particular environment. While tuning the voltage settings, target a concentration of 150,000 pt/cm

3

. An effective technique is to first remove the hood from the headform and allow the concentration inside to deplete. Make an incremental change to the pump voltage (~0.20 V) and replace the hood. Allow the concentration inside the hood to stabilize for one to two minutes afterwards. Repeat this process until the desired concentration is reached.


Aero Gen Pump V: Purge

This is the voltage setting during the mask purge cycle. At the beginning of each Test Mask function, the blower voltage is set to maximum voltage in order to blow about 50 liters per minute of air though the mask. This is called the mask purge cycle. The air from the mask is mixed with the output of the Aerosol Generator and this mixture is supplied to the Hood.

Since the volume of the hood is about 10 liters, it takes about 12 seconds to get one air exchange. For this reason, the aerosol concentration continues to build up inside the hood. After about 30 seconds, the blower v oltage is set to the “sample mask” mode. In this mode, the blower is supplying about 16 liters per minute of clean air to the mask, the voltage setting for this mode is determined by the “Aero Gen Pump V: Test” value.

This air then exits the mask and mixes with the output of the aerosol generator and enters the Hood.

Aero Gen Pump V: Test

This is the voltage setting during the mask sampling or “sample mask” mode. Normally this will be about 1.25 volts lower than the “Aero Gen

Pump V: Purge”. The difference between two voltage settings can be adjusted to assure similar aerosol concentration at the beginning and at the end of the mask sampling. If the aerosol generator voltages were kept at same value, the aerosol concentration inside the hood would continue to build up during the mask test cycle. If this were to occur, the aerosol concentration at the end of the mask test would be significantly higher than at the beginning of the mask test. This is avoided by reducing the Aerosol

Generator Pump V slightly.

Note

Voltage levels may need to be adjusted to accommodate different ambient and environmental conditions

H o w t o D e t e r m i n e

M a s k D T Vo l u m e

The mask DT volume is determined by injecting known volume of water accounting for any extra volume added due to adapters. Following is the procedure to determine mask DT volume:

1. Draw distilled or filtered water in to syringe and fill it with a known volume of water (10 ml or higher)

2. Connect the DT adapter to the mask DT

3. Hold the other end of the drink tube vertically up so that you can see the injected water as it starts to overflow

4. Start injecting water in to the DT adapter slowly until water starts to overflow on the other end of the DT

5. Measure the volume of water injected in to the DT. This is the volume of the DT adapter + DT

6. Remove the DT from the mask

7. Repeat the steps 4-5 for the DT adapter alone

8. Subtract the volume of DT adapter + DT volume from DT adapter alone to determine the DT volume.

9. Enter the DT volume for the Define Mask Protocol DT Full Volume value.

If the Mask has a Manual Valve, determine the DT Volume to Manual

Valve value in a similar manner.
