DONNING

The Air-Pack

warning
Warning!
  • The model used for this piece is extremely good looking and intelligent.
slide34

DONNING

  • Remove Facepiece from pouch
  • Check cylinder pressure. Min 4000
  • Reach inside right shoulder straps, grasp the redundant
  • alarm and pressure gauge, slide left arm through the Left shoulder straps
slide36

5. Fasten the waist strap, and pull tight for a snugfit. The weight is designed to be carried on the waist, not the shoulders.

slide37

6. As you straighten, pull the strap tabs out and adjust for a comfortable fit.

7. The shoulder and waist strap ends must be tucked in and lay flat across the body.

slide38

DONNING the FACEPIECE

1. Loosen the neck straps so the end-tabs are at the buckles.

slide39

DONNING the FACEPIECE

2. Insert your chin into the facepiece.

Note: harness may take a “memory” if stored over mask.

3. Pull the harness “net” over the crown of your head.

slide40

4. Tighten the neck straps; if necessary tighten the temple strap adjustments. Tuck in the straps so they lay flat across the head.

slide41

Facepiece fit check

First, check the inhalation valve. Inhale. If you do not receive sufficient flow of air, do not use the facepiece. The facepiece must be repaired or replaced.

slide42

Facepiece fit check

To check for facepiece fit, hold your hand over the inlet and inhale. Hold your breath at least 10 seconds.

The facepiece should collapse and stay collapsed against your face. If it does not, readjust the facepiece and test again. If this does not correct the leak, do not use the facepiece.

slide43

Test the exhalation valve, take a deep breath and hold it. Block the inlet with the palm of your hand and exhale. If the exhalation valve is stuck, you may feel a heavy rush of air around the facepiece. You may need to exhale sharply to open the valve if this does not release the valve, do not use the facepiece

open the cylinder valve fully
Open the Cylinder Valve fully

If air is flowing, push in the slide button on the MMR to stop air flow

Listen for any sound of hissing or popping from the Audi-larm Alarm or quick fill valves. If heard, place out of service.

slide46

As the pressure rises from 50 to 200 psig, both visible and audible alarms activate automatically, indicating that the alarms are functional. When the system is fully pressurized, the alarms enter the Monitor(normal) mode.

warning47
Warning

If the Audi-larm fails to ring, ICM, or HUD system fails to light and tone, place the SCBA out of service. All gauges should be within 225 psig of each other at 4500 psig. If not, place the SCBA out of service. Failure to follow these precautions may result in serious personal injury or death.

installing slide mask mounted regulator
Installing slide Mask Mounted Regulator
  • Grasp regulator and orient regulator so that the red bypass knob is pointing to the right and slide connector is on top.
installing slide mask mounted regulator50
Installing slide Mask Mounted Regulator
  • Slide regulator onto rail (fast track) of facepiece cover. Slide regulator down the rail until regulator stops.

Installing slide Mask Mounted Regulator
  • Insert regulator into facepiece by pushing upward.
  • Check proper engagement by pulling on the regulator to ensure the regulator is secure.
slide53

Check the bypass by turning the red knob counter-clockwise until you feel increased airflow. Close the bypass.

1 complete turn is fully open.

warning54
Warning

There must be a continuous flow of air when the bypass knob is opened. If not place the SCBA out of service. Failure to follow this precaution may result in serious personal injury or death.

slide55

MMR in the standby position on the mask.

Secure in storage position during overhaul or other tasks if still wearing scba.

slide56

Removing the SCBA

Push the release buttons on the top & bottom of the regulator and pull the regulator down and out of the facepiece.

slide59

When the pressure falls below 200 psig, turn the ICM off by pressing the reset (yellow) button* twice quickly.

*Both ICM 2000 series and TX series units turn off with the yellow/reset button.

slide61

To remove the facepiece, fully loosen the harness straps and pull the facepiece up and away from your face.

slide62

To remove the carrier harness, loosen the waist strap and press the belt buckle release button IN.

slide64

To loosen the shoulder strap, grasp the release loops. Push them out and away from your body.

Slip your right arm out of the shoulder pad first, then remove the harness.

slide65

Changing Cylinders

1. Be sure there is no pressure in the system. Disconnect the

Audi-larm coupling nut.

2. Lift and turn the latch wing to loosen the the cylinder clamp.

3. Slide out the empty cylinder and install one that is fully charged, ensure that the cylinder band latch is in the proper slot. Make sure lock tab on the carrier is fully engaged In the cylinder band slot.

4. Slide the new cylinder in the carrier with gauge out, turn latch wing.Push the latch wing toward the back plate, locking in place.

slide66

5. Ensure the cylinder is secure, to check, attempt to pull

the cylinder down and out, away from carrier.

If the cylinder feels loose, retighten and recheck.

6. Check that the O ring is inside the coupling nut. If the O ring

is damaged it MUST be replaced.

7. Thread the coupling onto the cylinder valve, hand tight.

slide67

Cold Weather Operations

To keep moisture from entering the MMR, stow the MMR in the stand by belt mount holder.

slide68

Cold Weather Operations

Watch for ice build up on the release buttons and bypass valve. Check for proper operation prior to entering a hazardous atmosphere.

slide69

Cold Weather Operations

When replacing cylinders, be careful to prevent moisture from entering the system. Water can contaminate the system and freeze.

slide70

Cold Weather Operations

Thoroughly dry the facepiece and MMR after cleaning.

slide71

Quick Fill System Operation

The Quick Fill system lets MSA airmask users refill and transfill air cylinders while the SCBA is worn, without the need to remove the air cylinder, even IN IDLH atmospheres.

slide72

Normal Use

  • If available, can quickly refill from secondary compressed air source to 4500 psi.

Emergency Breathing Support System

  • Transfill from Donor SCBA
slide73

Transfill from a Secondary Air Source

Key Points

  • Locate transfill adaptor on air source.
  • Remove the rubber dust covers from fittings.
  • Attach hose to the male fitting by pushing the

female fitting onto the male fitting

until it snaps in place.

  • Transfilling begins upon connection.
  • Compare gauge readings, disconnect by pulling

back the gray sleeve.

  • Immediately reinstall the dust cover.
  • Return to service.
slide74

Emergency Breathing Support System

Key Points

  • Donor SCBA should be @ or greater than 2000 psig +
  • Remove the emergency hose from pouch
  • Remove dust covers from the hose fittings.
  • Remove dust cover from male connection
  • Push the female fittings from the hose onto the male

fittings on SCBA until they snap into place.

  • Visualize gauges, after 30-60 seconds the pressure
  • will be equal.
  • Disconnect the hose from the SCBA’s, reinstall the dust
  • cover and return to fresh air.
slide75

Cleaning and Disinfecting

  • Water temperature NOT above 120

degrees.
