4. The amount of oxygen is sufficient to support life (that is, at least 19.5 percent oxygen
by volume at sea level). Do not use if oxygen concentration sufficient to support life is
questionable.
5. Respirator has passed a tightness test. (See Test for Tightness.)
6. Filters/Cartridges do not need to be replaced. Discard exhausted cartridges.
Failure to follow the above warning can result in serious personal injury or death.
REPLACING CARTRIDGES/FILTERS
The following conditions indicate that the cartridges have served their useful life and must be replaced:
FILTER CARTRIDGES:
Replace particulate filter cartridges whenever they are damaged, soiled or causing
noticeably increased breathing resistance.
To replace cartridges:
1. Remove the expended cartridges and dispose of properly.
2. Remove the replacement cartridges from storage bags.
3. Place cartridges on connectors carefully. Line up matchmark
on cartridge with small lug on facepiece connector. Make sure
cartridge connector lugs align with the cartridge opening. Push
down and tighten cartridge clockwise until the stops are engaged.
To ensure a good seal against the facepiece, tighten each cartridge
by gripping as much of the circumference of the cartridge as
possible and then slowly turning the cartridge until tight.
CLEANING AND DISINFECTING
• DO NOT use alcohol as a germicide because it may deteriorate rubber parts.
• Be careful not to inhale or touch the contaminant in handling the respirator or its parts. If
necessary, use equipment disposal to protect you from the specific contaminant.
• DO NOT force-dry the parts by placing them in a heater or in direct sunlight. The rubber will
deteriorate.
Failure to follow the above warnings can result in serious personal injury or death.
FACEPIECE
If the facepiece is to be decontaminated, remove the cartridges. The facepiece should first be cleaned
to remove dirt and oils. Then, disinfect for pathogenic micro-organisms after each use with the MSA
Confidence Plus 2 Cleaner (USA P/N 10009971, Canada P/N 10032737). Follow the instructions on
the cleaner for contact time for disinfection. Subsequently rinse thoroughly with plain warm water
(110° maximum, to avoid possible overheating and distortion of parts) and then air dry. OSHA 29 CFR
1910.134 states that all users shall be trained in the cleaning procedure. Note that although other
cleaner-disinfectants may have the same efficacy as the Confidence Plus 2 Cleaner towards micro-
