METHOD OF OPERATION Warning
RESPIRATORS SHALL NOT BE WORN
WHEN CONDITIONS PREVENT A
GOOD SEAL. SUCH CONDITIONS
INCLUDE, BUT ARE NOT LIMITED TO,
THE PRESENCE OF BEARDS,
SIDEBURNS, OR FACIAL HAIR, OR
CORRECTIVE LENSES WITH ARMS
THAT EXTEND OVER THE EARS.
Warning
THE BLOWER ASSEMBLY IS A
BATTERY-OPERATED ELECTRICAL
DEVICE THAT HAS NOT BEEN
EVALUATED AS AN IGNITION
SOURCE. THIS DEVICE IS NOT TO BE
USED IN A POTENTIALLY EXPLOSIVE
ATMOSPHERE. USE IN A
FLAMMABLE OR EXPLOSIVE
ATMOSPHERE COULD RESULT IN
IGNITION AND CAUSE SERIOUS
INJURY OR DEATH.
For this equipment to function as intended, the user must be wearing a t-tested respirator and facepiece that provides a
complete seal while maintaining visibility for the intended activities. Follow the manufacturer’s procedure for donning and
dong your mask.
MIRA Safety gas mask instruction manuals are included with purchase or are available by contacting Customer Service.
The blower assembly contains an electric motor driving a mechanical air blower. The battery pack compartment is in the
lower part of the blower assembly with an attached cap. The battery pack uses standard AA batteries due to their ready
availability and low cost.
The ON/OFF power switch is on the top front of the blower assembly. On the front, there are two (2) threaded inlets to attach
40 mm lters. The MIRA Safety MB-90 PAPR can use up to two (2) lters. New lters must be installed prior to use.
The waist belt supports the blower assembly at the waist or on a pack, and it is fully adjustable.
The MIRA Safety MB-90 is a Powered Air-Purifying Respirator (PAPR). The user of this
respirator breathes ambient air that has been passed through the attached lter
elements. The lter elements may include a mechanical lter to trap airborne
particulates or a sorbent bed of impregnated activated carbon to trap and/or neutralize
various gases and vapors. Filtration elements must be selected specically to suit the
hazardous atmosphere.
This equipment must be used with a functioning lter, gas mask/full-face respirator,
eight (8) AA batteries, and the included breathing tube. Once installed and turned on,
the blower will draw ambient air through the lter element and create positive pressure
inside the facepiece, aording protection from contaminants in the atmosphere while
enhancing breathing ease.
To maintain this level of protection:
The user must be wearing a properly tted and sealed gas mask with valve
covers and breathing tube properly tested and installed.
1
The blower must ALWAYS be turned on when the user is in a contaminated atmosphere.

USE SPECIFICATIONS AND
LIMITATIONS
The MIRA Safety MB-90 PAPR is intended for use as respiratory protection from airborne contaminants when used in
conjunction with a lter and gas mask/full-face respirator.
1
The personnel using this respirator must have read this manual completely, and, ideally, received training from their
employer or team leader prior to use. Each user must also have received training in the use of their existing respirator
equipment including, but not limited to, pre-use check, donning, seal check, use, dong and after-use care of the
respirator.
2
To use this equipment, you must follow the instructions regarding the use of the lter and gas mask/full-face
respirator you attach to it. Most (but not all) gas masks/full-face respirators are incompatible with facial hair. Beards,
sideburns, and other facial hair must be shaved clean so the mask can securely seal around its edges. Likewise, most
gas masks are not compatible with corrective lenses that could interfere with the seal. Consult your gas
mask/full-face respirator instruction manual for details.
3
The individual using the respirator must ensure it is properly inspected before use, properly decontaminated after
use (if necessary), properly cleaned and maintained after use, and properly stored between uses.
4
The MIRA Safety MB-90 PAPR (when used with compatible gas mask/full-face respirator and lter) protects only the
face and respiratory tract from airborne contaminants. Additional protective clothing, equipment, and headwear will
often be required, though it must not interfere with the operation of the respirator.
5
Use in explosive atmospheres is NOT PERMITTED. The MIRA Safety MB-90 PAPR contains a battery and must not be
taken into or used in atmospheres containing ammable or explosive gases, vapors, or dusts when the concentration
of such contaminants constitutes a re or explosion hazard.
6
The MIRA Safety MB-90 PAPR is NOT A TOY and should only be used according to the instructions herein. Do NOT
use the MB-90 PAPR for reghting, in oxygen-decient atmospheres, or for protection against contaminants that
the lter elements do not protect against.
7
The MIRA Safety MB-90 PAPR must NOT be used with expired or incompatible lter elements and/or gas masks.

USING YOUR MB90- PAPR
Ensure the power switch is in the OFF position and that the batteries are fully
charged. Turn the power switch ON briey to ensure the unit is functioning.
Turn the power switch OFF again.
1
The blower assembly and breathing tube must be arranged so that
There is enough slack in the
breathing tube for the user
to turn their head through
the full range of motion
without the breathing tube
pulling on the facepiece, the
breathing tube being
pinched closed, or the
breathing tube interfering
with other protective
clothing or equipment.
7
Inspect the PAPR and breathing tube as outlined in the PAPR MAINTENANCE
AND INSPECTION section of this manual.
2
Attach two (2) lter elements to the PAPR housing by threading them onto the
inlet ports until hand tight. DO NOT OVER TIGHTEN FILTER ELEMENTS.

Position the blower assembly at the back of either the right or left hip. When
properly donned, the power switch should be accessible.
6
a
The PAPR blower assembly
and breathing tube must be
positioned so that excessive
slack in the breathing tube
is not likely to catch on
objects.
b
If additional protective
clothing is used, it must be
arranged so that it does not
interfere with the t of the
gas mask or restrict airow
to the lter elements.
c
Page 4

Attach breathing tube and valve covers to the gas mask, ensuring the mask is eectively sealed and functioning
before attaching the breathing tube to the PAPR unit.
8
If, during use, the airow from the blower assembly should noticeably decrease or stop completely, or if inhalation
should become dicult, immediately leave the contaminated area. Decontaminate and, if necessary, check the
PAPR.
14
After four (4) hours of continuous use, the user must leave the contaminated area, decontaminate if required, and
inspect for damage.
13
If the airborne contaminant is detected by odor, taste, eye irritation, or if any discomfort is felt during use,
immediately leave the contaminated area. Decontaminate and, if necessary, check the PAPR.
15
If the battery compartment should become hot to touch, immediately turn the Power Switch to OFF. Do not
remove the facepiece, but continue to breathe through the respirator and immediately leave the contaminated
area. Decontaminate and, if necessary, check the PAPR.
16
Manually inspect the seals and junctions of your gas mask, breathing tube, and PAPR lter connectors to ensure
none are drawing air. This could indicate a faulty seal somewhere in the system.
Do not permit the batteries to completely discharge during use. Always monitor battery performance and change the batteries immediately after
use or if they expire.
10
Turn the power switch to the ON position. You should immediately notice improved airow within your gas mask.

Warning
IF THE POSITIVE AIR PRESSURE
FROM THE BLOWER CEASES FOR
ANY REASON, LEAVE THE
CONTAMINATED AREA AS SOON AS
IT IS SAFE TO DO SO. LACK OF
POSITIVE AIR PRESSURE FROM THE
BLOWER MAY REDUCE THE
RESPIRATOR PROTECTION WHICH
COULD RESULT IN SERIOUS INJURY
OR DEATH.
Temporarily positioning the PAPR blower assembly at the front of the waist will facilitate performing a negative leak
pressure test.
If, for any reason, the blower assembly stops operating, becomes very noisy, or the
battery compartment becomes hot to the touch, immediately leave the area requiring
respiratory protection, turn the power switch to the OFF position and determine the
cause of the problem.
Do not submerge the blower assembly in water during use as water will be drawn into the lter elements. If accidental
immersion occurs during use, leave the area requiring respiratory protection, turn the unit o, remove the respirator from
service, and tag it for inspection and repair. If it becomes impossible to inhale through the lter elements after accidental
immersion, proceed as directed above.
If, for any reason, it becomes impossible to inhale through the respirator during use,
the user may have to disconnect the facepiece from the breathing tube or remove
the facepiece. THIS WILL TERMINATE RESPIRATORY PROTECTION AND THE USER
WILL BE BREATHING THE ATMOSPHERE THE RESPIRATOR WAS INTENDED TO
PROTECT AGAINST.
PERFORMING A NEGATIVE LEAK
PRESSURE TEST
EMERGENCY USE
With the unit donned and turned o, close the inlet side of both lter elements by covering them with your palms
or other airtight objects, and press rmly to seal the inlets.
1
Inhale slowly and hold your breath momentarily. The mask should be drawn slightly in toward your face and stay
there, indicating there are no obvious leaks in the system.
2
If air leakage is detected during this procedure, remove and replace the facepiece following the gas mask/full-face
respirator donning procedure before repeating the test. If leakage persists, DO NOT USE THE EQUIPMENT.
3
In addition to poor facepiece t, leakage can result from loose breathing tube connections, improperly tightened lter elements, damaged or
missing gaskets at the breathing tube and/or lter element connections, a damaged or missing exhalation valve, or other damaged respirator
components. DO NOT USE A DAMAGED OR LEAKING RESPIRATOR. Make repairs and recheck respirator or remove from service and tag it for
repairs by authorized personnel.
To remove the breathing tube from the facepiece (if and when it is safe to do so), unthread the breathing tube from the facepiece.
