If a satisfactory quantitative fit factor (above 1000) or passing qualitative test cannot be achieved with any of the
masks, CleanSpace HALO must not be used.
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.
If a satisfactory Seal Check cannot be achieved, do not enter the contaminated zone.
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 leave the seal check cap in place for more than 2 minutes.
If you cannot adjust the mask to avoid your hairline, the mask is not suitable for you and must not be worn.
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.
When fitting a new filter, the blocked filter alarm shall be tested before the respirator is put back into service. See the
heading “Testing the Blocked Filter Alarm” below.
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.
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.
The Steri-Plus and HALO BIO Exhalation Filters (CS3039 and CS3027 respectively) are electrostatic filters and their
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 a possibility that the Exhalation
Filter has become contaminated with any solvent, replace it.
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.
