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. A LACK OF
POSITIVE AIR PRESSURE FROM THE
BLOWER MAY REDUCE THE
PROTECTION PROVIDED BY THE
RESPIRATOR, WHICH COULD
RESULT IN SERIOUS INJURY OR
DEATH.
Warning
IF YOU DETECT ANY CONTAMINANT
ODOR OR TASTE, OR EXPERIENCE
IRRITATION OF THE EYES, NOSE OR
THROAT, THERE MAY BE EXPOSURE
TO THE CONTAMINANT. RETURN TO
FRESH AIR IMMEDIATELY.
DETERMINE THE REASON FOR THE
EXPOSURE AND TAKE APPROPRIATE
CORRECTIVE ACTION BEFORE
CONTINUING USE OF THE
RESPIRATOR. FAILURE TO TAKE THE
PROPER CORRECTIVE ACTION MAY
RESULT IN EXPOSURE TO THE
CONTAMINANT, WHICH COULD
CAUSE SERIOUS INJURY OR DEATH.
Warning
IF THE BATTERY COMPARTMENT
BECOMES HOT, IMMEDIATELY
LEAVE THE AREA REQUIRING
RESPIRATORY PROTECTION. TURN
OFF THE EQUIPMENT AND ALLOW
IT TO COOL AT LEAST 60 MINUTES
BEFORE REMOVING THE BATTERY
PACK. DO NOT HANDLE BATTERIES
DIRECTLY IF YOU SMELL AN ACRID
ODOR.
The MIRA Safety MB-90 PAPR is designed to be used with a wide variety of CBRN gas
masks/full-face respirators and compatible NATO standard 40 mm filter cartridges. The
essential operation of this PAPR remains the same, provided you adhere to all
guidelines and instructions for your mask and filter cartridge.

pinched closed, or the
breathing tube interfering
with other protective
clothing or equipment.
