Properly cleaning SCBA components can help remove contaminants encountered during SCBA use. NFPA 1851 requires firefighters to evaluate PPE after each use to determine the appropriate cleaning level. MSA recommends carefully reviewing a copy of the current edition of NFPA 1851 to ensure full compliance.

During cleaning, be sure to wear adequate personal protective equipment in accordance with the detergent and cleaning instructions.

To clean the G1 Facepiece, follow these eight steps:

  1. Prepare to Clean: Fill sink with water and MSA Confidence® Plus 2 Germicidal Cleaner. Do NOT use cleaning products containing hydrocarbons or solvents.
  2. Submerge: Submerge the facepiece for a minimum of 30 seconds and make sure the cleaning solution enters all areas of the mask.
  3. Scrub: Scrub the facepiece inside and out with a soft, non-abrasive sponge or soft brush to make sure all contamination has been removed.
  4. Rinse: Rinse the facepiece inside and out with clean, warm 110° F water, preferably running and draining.
  5. Flush Exhalation Valve: Flush and manually operate the exhalation valve assembly by depressing the stem with a blunt, dull object. Be careful not to damage any rubber components on the facepiece.
  6. Shake: Shake the facepiece to remove all residual water.
  7. Wipe: Wipe and dry the facepiece inside and out using a soft, lint-free cloth.
  8. Air Dry: Allow the facepiece to completely air dry by resting it on the facepiece seal before putting it back into service.

Information regarding the inspection and cleaning of your MSA G1 Facepiece is available in the Operating Manual, which should be carefully reviewed and followed.
