User Safety Notice SN122223 – 3M™ Scott™ Cylinder and Valve Assemblies

Immediate Action Required

Impacted Dates:  October 3, 2023 – December 4 ,2023

3M™ Scott™ Cylinder and Valve Assemblies are safe to use once the instructions in this notice are carried out.

3M Scott have been made aware of a small number of cylinder valves that experienced noticeable rates of leakage upon initial inspection when the valve handwheel was initially opened. This has been investigated and found to have been caused by an O-ring failure at the bonnet due to incorrect torque on the specific units in question. The root cause has been identified and mitigated, but we are notifying all users of all cylinder and valve assemblies to perform the required inspections of their respirators on a regular basis as defined in our User Instructions provided with the respirator.

Identification and Customer Action

You are receiving this notice because you have been identified by 3M Scott as having purchased cylinders and/or valve assemblies from an authorized distributor that fall within the scope of this Notice. We have asked them to notify you.

If you own cylinder and valve assemblies, please inspect them in accordance with our User Instructions. If, after inspection, leaks are discovered, contact your 3M Scott Fire & Safety Authorized Service Center to complete the repairs required. Please note that it is unlikely a fielded SCBA, having been previously inspected and placed in service would be experiencing leaks of the type mentioned above. All 3M Scott User Instructions contain detailed guidance on the frequency and procedures for inspecting the respirator, including the breathing air cylinder and its components. See examples below in Figures 1. and 2. excerpted from 595373-01_E User Instruction for the 3M™ Scott™ Air-Pak™ X3 Pro Self-Contained Breathing Apparatus (SCBA), NFPA 1981 (2018 Edition).
