Cleaning and Disinfecting
WARNING!
• Do not use cleaning substances that can or might attack any part of the respirator.
• Do not use alcohol, which can cause deterioration of rubber parts.
• Do not use cleaning products that contain hydrocarbons or solvents such as nitro-thinner.
• Do not use radiant heat such as the sun or radiators to dry cleaned parts.
• When a drying cabinet is used, make sure the temperature is not more than 110°F (43°C).
• Make sure to rinse components thoroughly. The residue from cleaning agents can cause skin irritation.
• Make sure there is no water, moisture, or dampness on or in the facepiece and regulator before returning the respirator to
service. Any moisture on or in the facepiece or regulator can freeze and result in a malfunction of the respirator.
• Failure to clean and decontaminate the respirator correctly after each use can cause overexposure to contamination and
result in illness, disease, or death.
Failure to follow these warnings can result in serious personal injury or death.
MSA recommends the use of Confidence Plus Germicidal Cleaner (P/N 10009971), which cleans and disinfects components
in one operation; retains its germicidal efficiency in hard water to inhibit thegrowth of bacteria; and will not deteriorate rubber,
plastic, glass, or metal parts. Refer to the label to prepare the Confidence Plus Germicidal Cleaner.
If the Confidence Plus Germicidal Cleaner is not used, wash components in a mild cleaning solution and make sure to rinse
them thoroughly. Submerge the facepiece in a germicide solution for the manufacturer's recommended time.
The respirator must be cared for after each use and on a regular maintenance schedule. Thorough maintenance includes
cleaning and disinfecting, as well as inspection of components and parts replacement.
1. Remove excess dust from the respirator.
2. Unlatch the lens door.
3. Grasp the foam frame edge of the lens cartridge and carefully pull the cartridge out.
4. Remove the used protective lenses from the hood pocket and dispose of them properly.
5. Clean and disinfect the respirator components after separating them.
a. Unzip the collar. The collar may be cleaned in a washer and dryer similar to a conventional garment (110°F
maximum water and air temperature).
b. Disconnect the breathing tube from the facepiece.
c. Separate the facepiece from the hood. Stretch the rubber front of the hood over the lens housing assembly and
remove the facepiece.
