3. System Description CleanSpace HALO is a complete NIOSH-approved respiratory system. When used in accordance with its NIOSH approval, the respirator helps to provide respiratory protection against particulates. HALO does not provide protection against vapours or gasses and is not an intrinsically safe system. See the NIOSH Approval Section of these user instructions for additional information on approvals. The components of the CleanSpace HALO system are shown in Section 9. The blower draws ambient air through the high efficiency filter and supplies filtered air to the wearer via the mask. HALO is a breath responsive respirator which means that it blows harder during inhalation and more softly during exhalation. The device continuously adjusts fan speed to maintain positive pressure in the mask. Should the filter become blocked, an audible alarm will sound and the “Filter” light on the keypad will be illuminated. If the battery voltage falls below the minimum required to sustain the designed flow rate, an audible alarm will sound. The HALO BIO System includes a Head Cover which, in combination with the other HALO BIO components, helps protect the head and neck from splash contamination. The HALO BIO Head Cover is used with the HALO BIO Half Masks and HALO BIO filter. The HALO BIO System includes an exhalation filter. WARNING Properly selected, used and maintained respirators help to protect against certain airborne contaminants. It is essential to follow all instructions and government regulations on the use of this product, including wearing the complete respirator system during all times of exposure, in order for the product to help protect the wearer. Misuse of respirators may result in overexposure to contaminants and lead to sickness or death. For proper use, see your Occupational Health Specialist, these user instructions or contact CleanSpace Technology Customer Service on 1 888 804 0038

4. List of Warnings within these User Instructions WARNING

This product is part of a system that helps protect against certain airborne contaminants. Misuse may result in sickness or death. For proper use, see your Occupational Health Specialist, these user instructions or contact CleanSpace Technology Customer Service on 1 888 804 0038 WARNING Properly selected, used and maintained respirators help to protect against certain airborne contaminants. It is essential to follow all instructions and government regulations on the use of this product, including wearing the complete respirator system during all times of exposure, in order for the product to help protect the wearer. Misuse of respirators may result in overexposure to contaminants and lead to sickness or death. For proper use, see your Occupational Health Specialist, these user instructions or contact CleanSpace Technology Customer Service on 1 888 804 0038 WARNING: never dry the mask or exhalation valve with a cloth that may leave behind lint. Lint contamination of the exhalation valve may cause it to leak, resulting in overexposure to contaminants and lead to sickness or death. WARNING: The blower contains a battery, sensitive electronics and a motor. Never immerse it in water or use anything wetter than a damp cloth to clean it. No PAPR can fully protect you if you are not clean shaven. CleanSpace HALO is not suitable for users with facial hair. If a satisfactory fit factor cannot be achieved with any of the masks, CleanSpace halo must not be used If you cannot adjust the mask to avoid your hairline, the mask is not suitable for you and must not be worn Do not leave the seal check cap in place for more than 2 minutes Do not use compressed air or a brush to clean the filter!

3

HEPA filters are very easily damaged by the use of compressed air or by brushing. Misuse of CleanSpace HALO by cleaning the filter may result in overexposure to contaminants and lead to sickness or death.

Be sure to remove the Seal Check Cap (Half Mask variants) before entering the contaminated area. The Cap blocks the exhalation valve, making it more difficult for your exhaled air to be expelled from the mask. Failure to remove the cap will lead to build-up of Carbon Dioxide in the mask, and may result in headache or dizziness. Never leave the Cap in place for more than 2 minutes!

Do not remove the respirator until you have vacated the contaminated area unless you have pressing health reasons to do so (for instance you are experiencing dizziness and believe removing the respirator while you leave the contaminated area may help)

It is essential that the correct filter type is selected for the chosen application.

If the blocked filter alarm is triggered (2 beeps, repeated every second, red LED flashes), leave the contaminated area immediately and replace the filter. Operating the respirator after the blocked filter alarm has sounded can cause the flow to fall below the manufacturer’s minimum designed flow, which may result in overexposure to contaminants and lead to sickness or death. CleanSpace HALO is not intrinsically safe. Do not use in flammable or explosive atmospheres. Doing so may result in injury or death. Always correctly use and maintain the internal lithium ion battery packs. Failure to do so may result in fire or explosion or could adversely affect respirator performance and result in injury, sickness or death. Do not charge the on-board battery with unapproved chargers, in enclosed cabinets without ventilation, near flammable liquids or gasses, or near sources of high heat. Do not immerse the device in water. Do not use, charge or store the device outside the recommended temperature limits If the battery alarm sounds (3 beeps, repeated every second), leave the contaminated area immediately and re-charge the battery. Operating the respirator after the low battery alarm has sounded can cause the flow to fall below the manufacturer’s minimum designed flow, which may result in overexposure to contaminants and lead to sickness or death. In the extremely rare circumstance that the battery is damaged and electrolyte comes in contact with eyes, flush with water immediately and seek urgent medical attention You must recalibrate the internal pressure sensor any time that your CleanSpace HALO is exposed to changes in temperature of more than 20°C When fitting a new filter, the blocked filter alarm shall be tested before the respirator is put back into service. The Exhalation Filter CS3027 is an electrostatic filter and its performance will be degraded by exposure to certain organic solvents including isopropanol (IPA), xylene and toluene. Always remove the Exhalation Filter before cleaning the mask. If there is any possibility that the Exhalation Filter has become contaminated with solvent, replace it

6. S - Special or Critical User Instructions This respirator contains a system for synchronising with your breathing and regulating mask pressure. This system requires re-calibration whenever it experiences a change in temperature of more than 36°F (20°C). It is best practice to also re-calibrate if the unit has been in storage, particularly if the storage temperature is not known. For the most accurate battery charge indication, the respirator must be plugged into its charger. To be sure it is fully charged, plug in the charger and wait for all 3 LEDs to light solidly without flashing. If the 3rd LED is flashing rapidly, the battery is 95% charged. The CS3024 Head Cover shall only be used in combination with a HALO BIO Half Mask (CS3003H Small, CS3004H Medium or CS3005H Large); and with a CS3025 Filter HE – HALO BIO. No other combination of mask and filter is approved for use with the HALO BIO Head Cover. The HALO BIO Masks are approved and may be used without the Head Cover with either the HALO BIO HE Filter (CS03025) or the HALO Standard HE Filter (CS3022). The HALO BIO is a tight-fitting half mask PAPR. The head cover does not provide or contribute to the systems respiratory protection.

11. Controls and Indicators

POWER BUTTON This button is used to switch between the three (3) operating Modes: “On”, “Standby” and “Off” Mode. i) Standby Mode is when the green battery indicator lights are on, the motor is not running and there is no airflow to the mask. The respirator will automatically switch to Standby Mode within ten (10) seconds of the user taking it off. If the respirator is in Off Mode it will switch to Standby Mode when the Power button is pressed. ii) On Mode is when the respirator is being worn, the motor is running and there is air flow to the mask. The motor will start (called On Mode) when the respirator detects a change in pressure in the mask triggered by your breathing. In On Mode you should hear the motor running and feel the airflow on your face. You can also switch to On Mode (start the motor) from Standby Mode by pressing the Power button once. iii) Off Mode is when the green battery indicator lights are off and the motor is not running and there is no air flow to the mask. The respirator automatically switches into Off Mode three (3) minutes after it has been removed from the user’s face and the sensors detect that there is no breathing. To conserve battery life, the respirator is designed to automatically switch from On Mode to Standby then to Off Mode when not being worn. Important: CleanSpace HALO™ switches into On Mode when it is in Standby Mode and the wearer starts to breathe. The respirator can only switch into On Mode from Standby Mode.

9

FLOW TEST BUTTON This button is used to check that the respirator is able to deliver its minimum designed flow. Pressing it once, when the CleanSpace HALO is in Standby Mode (not ON Mode), starts the flow test which lasts about 5 seconds. See Section 0 for instructions on running the flow test.

BATTERY INDICATOR LIGHTS Your respirator is equipped with an indicator of battery charge. There are three (3) battery indicator lights. With the charger plugged in and three green lights lit, the battery is fully charged and typically has six (6) hours of operating time. The respirator should be fully charged before use. If you need to be sure the battery is 100% charged plug in the charger. Even if the battery is fully charged, the 3rd LED will flash for at least three minutes while the respirator checks its condition. Once all 3 LEDs light solidly without flashing the battery is at 100%

For how to assess the level of charge, see Section 16. When the battery approaches a level at which it would not be able to supply the Manufacturer’s Minimum Design Flow, an alarm sounds (3 beeps, repeated once per second). All green battery lights are extinguished. If the low battery alarm sounds you must leave the contaminated area immediately and recharge the battery. Operating time is strongly affected by work rate, altitude, and other factors. The operating times quoted above are average durations at moderate work rates at sea level. Actual operating times may vary widely from average durations.

FILTER WARNING ALARM CleanSpace HALO™ has a Filter Warning Alarm, which is triggered when the filter is blocked. If the Filter Warning Alarm sounds (two beeps, repeated once per second) or the Filter Warning Alarm light comes on, you must move out of the contaminated area, and change the filter.

12. Mask Fitting Before using your respirator you must determine the right mask for your face and know how to adjust the machine to achieve a good fit. It is vital that your mask is the right size for your face and fits properly. Mask fitting must be carried out by a specialist / designated mask fitter. The fit must be confirmed by a quantitative fit test performed according to OSHA regulations 1910.134. Full Face masks and Half Masks require different equipment and instructions to carry out a quantitative fit test. Half Masks: To carry out a quantitative fit test your specialist mask fitter will require PAF-0025 PortaCount Adaptor and the accompanying S005-7174 Quantitative Fit Test Instructions. The PortaCount Adaptor is an accessory that fits between the mask and the exhalation valve and allows the air in the mask to be sampled. It comes with detailed instructions on how to carry out a quantitative fit test. Full Face Masks: See Appendix - Performing a Quantitative Fit Test (Full Face Mask). No PAPR can fully protect you if you are not clean shaven. CleanSpace HALO is not suitable for users with facial hair.

10

MASK SELECTION GUIDELINES No set of guidelines can ensure that you have the right size mask for your face. You must confirm the fit with a quantitative fit test. But the tables below will help your mask fitting specialist to select the mask most likely to fit you and may therefore save time.

Half Masks:

Full Face Masks:

11

SELECTING A NECK SUPPORT Your CleanSpace HALO respirator is supplied with two sizes of neck support, “S”, “M”. “S” (Small) is for people with smaller necks and heads while “M” (Medium) is for those with medium sized heads and necks. Users for whom the “Medium” neck support does not provide enough room (both bellows are fully extended but mask is still too tight on face) should use HALO without a neck support. This configuration provides extra room and is comfortable due to the curved design of the case. Once you have achieved an acceptable mask fit and confirmed it with a quantitative fit test, record your information in the table below.

13. Using CleanSpace HALO with HALF MASKS (including HALO BIO Half Masks) Complete the following five steps each time you use your respirator with a Half Mask.

STEP 1 - INSPECT Before each entry into a contaminated area, the following inspections must be performed: •

•

Visually check the entire respirator system including the blower, mask, harness and filter. If parts are missing or damaged replace them only with approved parts before proceeding. Check the top and bottom case of the blower for cracks or other damage. Do not use the device if there is any damage. Remove the HE filter and check it carefully. The seal must be clean and free from damage of any kind. If necessary it can be cleaned with a cloth dampened with water. Examine the visible internal surfaces for any sign that dust has leaked past a damaged seal. If found, replace the filter. The body of the filter must not be cracked or show any sign of damage. Examine the filter carefully for any sign that it has sustained an impact or been scratched. If any sign of impact or scratching is found, discard the filter. Refit the HE filter (see Changing the Filter, page 28) DO NOT USE COMPRESSED AIR OR A BRUSH TO CLEAN THE FILTER! HEPA FILTERS ARE VERY EASILY DAMAGED BY THE USE OF COMPRESSED AIR OR BY BRUSHING. Misuse of CleanSpace HALO by cleaning the filter may result in overexposure to contaminants and lead to sickness or death.

12

• • • •

•

Check that the battery is fully charged by pressing the power button. All three battery LEDs must light. See Section 14. Check both bellows for splits or holes. Check that the bellows have not become distorted so as to partially or fully close the air path to the mask. Check the mask to ensure that there are no cracks, tears or dirt; check the mask is not distorted. Check the exhalation valve for damage or dirt. If it is dirty, remove the exhalation Valve Cover. Remove any dirt, hairs or anything that could affect the seal of the valve against its seat. Check that the valve seat is clean. Reinstall the Valve Cover. If the valve is damaged, replace the mask. A dirty or poorly sealing valve will reduce protection and shorten battery life. Check the harness is intact and the elastic is not frayed or damaged. It must be adjusted to support some of the weight of the respirator.

STEP 2 – CALIBRATE This respirator contains a system for synchronising with your breathing and regulating mask pressure. This system requires re-calibration whenever it experiences a change in temperature of more than 36°F (20°C). It is best practice to also re-calibrate if the unit has been in storage, particularly if the storage temperature is not known. To re-calibrate: 1. 2. 3. 4.

Remove the mask if fitted. Remove the filter from the respirator. Place the respirator on a stable surface such as a table. With the respirator in standby mode (one or more green LEDs lit), press the Power button and the Flow Test button at the same time. If no LEDs are lit. press the Power button once to enter standby mode 5. When both the blue and red LEDs light, release both buttons. Leave the respirator sitting still. 6. After 5 – 10 seconds the motor will start and will run for 5 – 10 seconds. 7. When the motor stops, calibration is complete. 8. Re-fit the filter. Important Note: Failure to remove the filter prior to calibration will result in poor battery life. In order to restore the performance of the respirator, calibration must be performed again with the filter removed.

STEP 3 – TEST FLOW RATE This test checks that the machine is able to deliver the Manufacturer’s Minimum Design Flow of 120 litres/minute. 1.

Remove the mask from the respirator. Leave the filter in place. Place the respirator flat on a table or other support.

2.

Press and release the button marked “Flow Test”

3.

The respirator automatically runs the Flow Test. The motor will run fast and air will be discharged from the left hand bellows.

4.

After 2 seconds the respirator reports the result of the test using the LEDs on the keypad. Use the table below to interpret the LEDs. LIGHTS

Meaning

3 LEDs:

PASS (Excellent: flow >180 l/min)**

2 LEDs:

PASS (Good)**

1 LED:

PASS (Acceptable)

ALL LEDs FLASH

FAIL (Flow <120 l/min) Do not use the respirator until a new filter has been fitted and / or battery charged and the test has been repeated with a PASS result. Reset the respirator by pressing the Power button. Fully charge the battery and / or replace the filter. Repeat the flow test. If filter is new and battery fully charged but the respirator fails the test, contact CleanSpace Technology and do not use until it has been evaluated

** This test is not a battery charge test. Three LEDs means that, as of the moment it is tested, the unit can deliver high flow. It does not mean the battery is full. You must check the battery condition separately. See Section 16.

13

STEP 4 - DON THE RESPIRATOR NOTE – please read STEP 4 all the way through before beginning to don the respirator Locate your blower, mask, neck support and harness. Make sure the mask is the size that you used for your last successful quantitative fit test. This size should be recorded in this manual (see Section 11 above). Fit a mask to CleanSpace HALO • With the peak of the mask upright locate the right-hand mask AirClip. Locate the right-hand blower AirClip. It is on the same side of the blower as the Keypad.

Figure 5 - Right hand mask AirClip

Figure 6 - Right hand blower AirClip

Join the AirClips, so that the mask is attached to the blower. See Figure 7.

Figure 7 Mask on Blower (Note - connection is on right hand side)

14

Check that the mask is the right way up! The nose region of the mask must face in the same direction as the keypad. See Figure 8.

Figure 8 - Nose section of mask and keypad must both face up Leave the other mask arm and bellow free until you are fitting the Respirator. Familiarise yourself with the Adjust Buttons and the Mask Release Buttons. See Figure 9

Figure 9 - Mask Release Button and Adjust Button •

Fit the Harness Holding the harness find the two keyhole clips at the end of each elastic strap, fit these to the buttons on the inside of each Airclip. Check that the “Front” printing on the main head strap is pointing to the mask and that there are no twists in the straps.

Figure 11 – Adjust Harness Length by Moving Cleat Up or Down Strap Adjust the harness as follows: To move the mask up, tighten the elastic straps by sliding the cleat down the strap • To adjust for a smaller head size, shorten the rear strap by using a hole further along the • strap, as shown below.

Figure 12 - Adjusting the harness rear strap

•

Fit a Neck Support Align the neck support with the blower, the two arms with the rounded heads should be at the top. Locate the bottom arms of the neck support in the grooves at the bottom of the unit and slide neck support upwards until you hear a ‘click’. NOTE – Users for whom the “Medium” neck support does not provide enough room (both bellows are fully extended but mask is still too tight on face) may use HALO without a neck support. Note that this configuration (like all others) must be confirmed by a quantitative fit test performed according to OSHA regulations 1910.134

16

Figure 13 - Fitting neck support •

Loosen both bellows to their widest opening Press the adjust button on the blower and pull on the bellows to extend them. See Figure 14.

Figure 14 - Adjust Button

•

Place the machine in Standby Mode Press the Power button once

•

Don the respirator and start to breathe. (The motor should start) Place the blower behind your neck with the bellows and mask hanging down one side, harness should be hanging in front of mask. Fasten the AirClip on your left-hand side. Pull the mask up and around onto your face. Pull the harness back and onto your head. Adjust harness and settle it on your head, move cleats up or down to adjust.

Breathe normally. The motor should start and you should feel fresh air on your face. If the motor does not start, it was not in Standby Mode. Take the respirator off, press the Power button to activate Standby Mode and don it again as described above. Check the Harness The Harness should take a little of the weight of the mask and support the blower so that the respirator system sits level on your head. If necessary adjust the harness. This is done by shortening or lengthening the front straps of the harness, by sliding the cleats up or down the straps. Remember to shorten or lengthen each side by the same amount. If necessary the rear strap can also be adjusted – see above.

Figure 22 - Tightening Mask

STEP 5 – CHECK MASK SEAL (STANDARD MASK) If using the HALO BIO system CS3024 Head Cover, skip to Section 14 It is essential to do a fit check every time you wear a CleanSpace HALO Locate PAF-1009, the red Seal Check Cap. Fit Seal Check Cap over the exhalation valve in the mask. The Cap should snap into place. See Figure 23.

Figure 23 - Fitting Seal Check Cap Check that no air is flowing from the exhalation valve. Breathe normally. Using your fingers, feel around the perimeter of the mask for leaks. You will feel any leak as a cool flow of air over your finger. For greater sensitivity breathe out firmly to raise the mask pressure. Wetting your fingers will make it easier to feel tiny leaks. If necessary tighten the mask. To tighten the mask, place one hand against the back of the blower and the other over the front of the mask. Push the blower forwards and the mask back, tightening the fit. You will hear a series of clicks as the mask is tightened. Be careful to tighten each side by the same amount. After each tightening, feel for leaks again Tilt your head down (look at the ground) and up (look at the sky). Check that there are still no leaks. Look right and left, checking for leaks. Adjust if necessary. Once you can feel no leaks from the mask, the seal check is complete. IF A SATISFACTORY FIT CANNOT BE ACHIEVED, DO NOT ENTER THE CONTAMINATED ZONE

Remove the Seal Check Cap by gently twisting the handle so that one side of the cap comes loose from the exhalation valve. Be careful not to dislodge the exhalation Valve Cover. See Figure 24.

19

Figure 24 - Removing Seal Check Cap Be sure to remove the Seal Check Cap (Half Mask variants) before entering the contaminated area. The Cap blocks the exhalation valve, making it more difficult for your exhaled air to be expelled from the mask. Failure to remove the cap will lead to build-up of Carbon Dioxide in the mask and may result in headache or dizziness. Never leave the Cap in place for more than 2 minutes!

14. Using CleanSpace HALO BIO with the Head Cover If you are using the HALO BIO Head Cover, carry out the following additional steps

STEP 1 – CHECK MASK SEAL •

Check that you are using a HALO BIO mask (CS3003H, CS3004H or CS3005H) with the blue Snorkel Exhalation Valve Cover on the front

•

Check that you are using CS3025 Filter HE – HALO BIO, with the blue inlet tube

•

Don the Head Cover

•
