11 Cleaning and Disinfection

Depending on the cleaning policy adopted, either a designated person or the user should clean each

device after each use. ANSI standards suggest that users should be trained in the cleaning procedure.

Confidence Plus

Cleaning Solution (P/N 10009971) from MSA is recommended. It cleans and disin-

fects in one operation. It retains its germicidal efficiency in hard water to inhibit the growth of bacteria.

It will not deteriorate rubber, plastic, glass, or metal parts. Refer to the label for user instructions.

If the SCBA is soiled (i.e. heavy smoke residue or dirt accumulation) use a sponge damp with mild

soap solution or use a soft/medium bristle brush to remove deposits that may interfere with normal

operation of:

- Harness (straps and buckles)

- Carrier (band and latch assembly)

- Cylinder (handwheel, gauge, outlet connection)

- Pressure reducer (bell and coupling nut connection)

- Control module/power module/battery module/speaker module

 Inspect the entire SCBA as it is reassembled. Follow the Inspection Instructions.

Preparing Solution

Follow the instructions with the Confidence Plus

Cleaning Solution.

If the Confidence Plus Cleaning Solution is not used, wash in a mild cleaning solution, rinse thor-

oughly, and submerge in a germicide solution for the manufacturer's recommended time.

WARNING

- DO NOT use any cleaning substances that can or might attack any part of the SCBA.

- DO NOT use alcohol because it may deteriorate rubber parts.

- If not rinsed thoroughly, cleaning agent residue may irritate the wearer's skin.

Failure to follow these warnings can result in serious injury or death.

Cylinders 12 Cylinders 12.1 Safety Precautions for MSA Self-Contained Breathing Apparatus Cylinders WARNING - - - - - This system must be supplied with respirable [Quality Verification Level (Grade) D, see ANSI/ CGA G-7.1-1989] or higher quality air; and a dew point not to exceed -65°F/-54°C (24ppm v/v) [Compressed Gas Association Specification G-7.1 for Quality Verification Level (Grade) D Gaseous Air]. In fire service applications, MSA recommends breathing air quality in accordance with NFPA 1989.
PAGE 5
Cylinders Cylinders should not be stored partially charged: If used partially charged, the duration of the SCBA is reduced. The pressure relief device is only designed to protect a fully charged cylinder from the effects of a fire. For maximum safety, the cylinders should be stored full or at a pressure above ambient but less than 100 psi. - Prior to recharging, cylinders must be examined externally for evidence of high heat exposure, corrosion, or other evidence of significant damage.
PAGE 6
Cylinders 12.2 Preparing Cylinder for Use For remote connection, the cylinder must have the dove tail bracket attached prior to use. If the dove tail is not equipped, the following instructions must be followed. (1) Remove the old cylinder boot and insert (if present) from the cylinder. (2) Determine which cylinder retainer kit is needed (if you already have existing MSA cylinders). New cylinders with retainer kits already installed are available for purchase.
PAGE 7
Cylinders (3) Attach the retainer halves to the cylinder valve. (4) Apply 3 screws to retainer.  The screws must be torqued to 4 inch-pounds. (5) Place the new rubber boot (P/N 10146897) over cylinder valve gauge and attach to retainer. (6) Ensure retainer is not loose on cylinder valve.

Cylinders 12.4 Changing the Cylinder Removing the Cylinder (1) Lay the backplate of the SCBA horizontal with cylinder facing up. (2) Ensure there is no pressure in the system before replacing a cylinder. (3) Close the cylinder valve. (4) Turn the regulator bypass counter-clockwise or press purge until air no longer discharges from the regulator. (5) Close the bypass by turning the knob clockwise.
PAGE 10
Cylinders WARNING Care must be taken to protect the quick connect coupling and adapter from damage, dirt, and debris during cylinder replacement. Dirt and debris can cause the cylinder connection seals to leak. Visually inspect the coupling and adapter prior to connection. If dirt or debris is observed, the material must be removed prior to connecting the cylinder.

UAC Fitting 13 UAC Fitting All NFPA 1981, 2013 Ed. approved SCBAs are equipped with a UAC (Universal Air Connection) fitting. The UAC fitting is a male Quick-Fill inlet for use by Rapid Intervention Teams for emergency filling operations. The system also includes an automatically resetting pressure relief valve. The SCBA can also be equipped with a waist mounted Quick-Fill System. For additional information on using the Quick-Fill System, refer to the Quick-Fill System section of the manual.
PAGE 12
UAC Fitting 13.2 Filling Instructions A secondary air supply stores compressed breathing air until needed to refill SCBA air cylinders. When transfilling, the secondary air supply pressure must be greater than SCBA cylinder pressure. Examples of air supplies include: cascade air cylinder refilling systems; high pressure compressor systems with a fixed reservoir; or a portable air system such as the RescueAire™ System.
