SCOTT 4.5 Airpack
Manlius Fire DepartmentAnnual SCBA & RIT Pak Familiarization Drill
OBJECTIVE: Given the Scott 4.5 SCBA, firefighters will be able to identify the parts and functions of the SCBA and RIT Pak and use the SCBA and RIT Pak as described in the Scott User Manual
OBJECTIVE: Given the Scott 4.5 SCBA, firefighters will be able to
properly donn the SCBA and mask as described in the Scott User Manual.
OBJECTIVE: Given the Scott 4.5 SCBA, firefighters will be able to safely connect the RIC connection as described in the Scott User Manual
OBJECTIVE: Given the Scott 4.5 SCBA and a RIT Pak or another Scott SCBA, firefighters will be able to identify several methods of providing supplemental air to a downed firefighter.
TERMINAL LEARNING OBJECTIVES

Smooth ½ turn
After initialization, the rectangular indicator lights will show the level of the air supply in the cylinder as follows:
FULL: 2 green lights glowing near the center of the display
THREE-QUARTERS: single green light glowing.
ONE-HALF: yellow light flashing slowly at once a second.
ONE-QUARTER cylinder end of service time indicator is indicated by the red light at the far left flashing rapidly at ten times a second.
When this warning light is flashing rapidly, the user must leave the hazardous atmosphere immediately.
Heads Up Display
HEADS-UP DISPLAY (HUD)
Visual display of SCBA air status
Series of lights indicate pressure◦ Full - 2 green◦ 75% - 1 green◦ 50% - 1 yellow slow flashing◦ 25% - 1 red rapid flashing
Adjust the head straps to their full outward position. Hold the facepiece in one hand and hold the head
harness by the strap at the base of the head net. Place the facepiece on the face with chin properly
located in the chin pock et while pulling the head harness over the top of the head. Verify that no hair or clothing is interfering with the face to facepiece seal. 12 A
Tighten the neck straps by pulling the two lower strap ends toward the rear of the head.
12 B
How to Don AV 3000 Mask
Stroke the head harness net down the back of the head using one or both hands. Verify that the head harness is lying flat against the back of the head. Retighten the neck straps. 12C
Tighten the two temple straps. Adjust the temple straps by pulling the two temple strap ends toward the back of the head. Over-tightening may cause discomfort. 12D
Retighten the neck straps if required.
Donning mask…
Fully depress the center of the air saver/donning switch on top of regulator and release.
The breathing regulator is equipped with an air aver/donning switch to prevent the rapid loss of air supply when the cylinder valve is open and the facepiece is removed from the face or the regulator is removed from the facepiece.
Attaching Regulator
If the regulator is not attached to the facepiece, proceed as follows:
◦ Verify that the regulator gasket is not damaged and is in place around the outlet port of the regulator.
◦ Align the two flats of the regulator outlet port with the corre sponding
flats in the facepiece port (the red purge valve on the regulator will be in the 12 o’clock position). insert the regulator into the facepiece port.
Rotate the regulator counterclockwise (as viewed from inside of facepiece) until the red purge valve knob is on the left side of the facepiece. The lock tab on the regulator will lock into the facepiece retainer with a “click.” when the lock tab is properly engaged, the regulator will not rotate.
Attaching Regulator
Slowly open cylinder valve fully by turning the valve knob counterclockwise until it stops (approximately 2 1/2 full turns of the knob).
Attaching Regulator
Observe the operation of the alarms:
◦ The VIB RALERT end of service indicator alarm will actuate and then stop.
◦ The HEADS-UP DI SPLAY shall initialize for twenty (20) seconds and then display the cylinder level.
◦ The PAK ALERT SE 7 distress alarm will actuate when the cylinder valve is opened and will sound three quick audible chirps accompanied by a green flashing on the PAK ALERT SE 7 control console
Attaching Regulator
If the air saver/donning switch has not been depressed prior to opening the cylinder valve, the VIB RALERT Alarm will not actuate due to the air flowing freely on the facepiece.
With facepiece sealed to face, inhale sharply.
Attaching Regulator
Always check the facepiece seal, the system seal, and the operation of the end of service alarms using the following procedure:
◦ Completely close the cylinder valve by pushing in on the cylinder valve and rotating it clockwise.
◦ Breathe on respirator. As the air pressure falls in the respirator, one or more of the end of service indicator alarms will actuate.
◦ Immediately on actuation of any end of service indicator alarm, hold breath momentarily and make certain that the Vibralert and heads up display both actuate (rapid clicking of the Vibralert Alarm, rapid flashing of the heads up display red light.
◦ Resume breathing on the respirator until all air stops flowing from the breathing regulator.
◦ NEGATIVE PRESSURE LEAK TEST:Inhale slowly and hold breath momentarily. No leakage of air shall be detected into the facepiece and the facepiece shall be drawn slightly to the face.
◦ Open cylinder valve and breathe normally. If installed, the electronic end of service time indicator will continue briefly then stop.
The respirator may be donned and worn in "Standby," so that it is ready for use. This means the respirator is in place on the user’s body with the shoulder straps properly adjusted and the waist belt buckled, but the facepiece is not donned (sealed to the face) and the respirator is not being used.
Use in Standby mode
Leave the cylinder valve fully open and verify that the air saver/donning switch is depressed.
Remove the facepiece but leave the regulator attached to the facepiece.
Keep the facepiece ready for use either of two ways:◦ Hang the facepiece from the snap clip on the left
shoulder pad,◦ Hang the facepiece from the optional neck strap.
NOTE DO NOT LET THE FACEPIECE HANG LOOSE WI THOUT SECURING IT AS NOTED ABOVE.
The regulator can be detached from the facepiece until needed. To detach the regulator from the facepiece:◦ Place your right hand over the cover with your thumb on
the lock tab.◦ Pull the lock tab toward the cover and rotate the
regulator ¼ turn clockwise (viewed from inside of facepiece).
◦ W hen the red purge valve is in the 12 o’clock position remove regulator from the facepiece.
◦ The regulator can be stored in the optional regulator holder on the waist belt.

Respirators must be cleaned after every use
We use a solution to clean the mask
We are not cleaning them as frequently as we need to. They carry carcinogenic remnants of fires.
