Air Bottle

SCOTT 4.5 Cylinder

4500psi.

60 minute rated air supply

Remote Gauge Console

Analog gauge showing the total available air pressure left in your air cylinder

LED display with lights indicating the remaining air in the same format as the heads-up display

There is a round red low battery light

Pressure Reducer

Reduces bottle pressure to 160psi. And delivers it to the low pressure side

Built in bell which sounds at ¼ bottle pressure or 1000psi.

Facepiece/Emergency Breathing Regulator

The mask is a special configuration of the AV3000 SureSeal facepiece

It has no nose cup or voice mitters

There is a special head harness with large rings built in to the securing straps

Emergency Breathing Regulator has no heads-up display or low air vibralert

Daily Check/Inspection

The RIT pack must be inspected at the start of each shift.

Bottle Inspection

Check for the latest hydrostatic test date and make sure it is within 5 years

Make sure the bottle is within 15 years of the manufacture date

Visually inspect the cylinder for and obvious damage

Check the cylinder pressure for fullness or above 4000psi.

RIT Bag Inspection

Any signs of damage or contamination

Make sure the shoulder strap seat belt buckles work and the carabineers open and close freely

All rings are attached and in place

Check hard plastic bottom for any cracks or holes

Hoses/Facepiece/Regulator Inspection

Fully extend high/low pressure hoses from storage compartments and check for damage and contamination

Check mask for cleanliness and damage

Make sure straps on head harness are fully extended

Visually inspect the regulator and regulator hose for damage

Check the male coupling on the emergency regulator hose for damage and ware

Basic Operation

Turn the cylinder valve on and listen for leaks

Observe the LED display on the remote gauge and make sure all 5 lights stay lit for 20 seconds. Followed by the light which marks the air level.

Check the remote pressure gauge and make sure it is within 10% of the bottle pressure

Basic Operation Cont.

Attach regulator to mask and don the mask

Check the air saver/donning switch and purge valve for proper operation

Remove the facepiece and make sure the regulator free flows by pushing the air saver/donning switch

Turn bottle off

Basic Operation Cont.

Bleed the purge valve and observe the pressure indicator lights to make sure they are all operational

Make sure low air bell sounds at ¼ bottle pressure or 1000psi.

Low Pressure Air Supply

Description

Options of the Low Pressure System

Low Pressure Air Supply Description

The low pressure hose is 78” long

The low pressure air supply is to replace the depleted air cylinder of the firefighters SCBA or to supply breathing air to the firefighter with a facepiece and regulator

Low Air Supply Options

Connecting to buddy breather hose or EBSS (emergency breathing support system)

Connecting emergency breathing regulator

Use of emergency facepiece and emergency regulator

Connecting to the Inerspiro buddy breathing ports

Connecting to Buddy Breather Hose

Connect the victims Buddy Breather low pressure hose to either of your male or female quick connect coupling on the low pressure regulator

If victims cylinder valve is open air will continue to be supplied from their cylinder until the pressure drops below the supply pressure from the low pressure air line assembly

Connecting To Buddy Breather Hose Cont.

If victims cylinder valve is off or his bottle is empty the only source of air will be from the RIC Pack

This is the way to deliver the longest breathing time to the victim

The victim gets the 60min. bottle plus whatever he has left in his bottle

Connecting to Buddy Breather Hose Cont.

This method is the fastest and easiest

If victim is entrapped it gives him the longest time to breathe for extended extrication

The victims facepiece and regulator must be intact and working

Indications for Connecting Emergency Breathing Regulator

The victims SCBA does not have any quick disconnects suitable for attachment

The regulator is clearly damaged

If the fastest way to provide breathing air is to replace the victims breathing regulator

Connecting Emergency Breathing Regulator

Make sure the regulator is attached to low pressure manifold

Attach to victims facepiece with a ¼ turn and make sure the regulator locks

If air saver/donning switch does not open from the victim breathing, open the purge valve to supply the victim with air

Secure low pressure hose to victim

Indications for Administering the Emergency Facepiece

The victims air pack is not compatible with the SCOTT air packs or RIT Pack III

The victims facepiece is damaged

The victim is not wearing a facepiece or an SCBA at all

Administering the Emergency Facepiece

Make sure the facepiece is attached to the regulator and the regulator is attached to the low pressure manifold

Loosen existing facepiece harness and hold the facepiece against the victims face

Quickly remove the victims facepiece and replace it with the emergency facepiece

Administering the Emergency Facepiece Cont.

If the saver/donning switch does not open from the victim breathing, open the purge valve to supply the victim with air

Secure the mask to victim by tightening head harness straps from bottom to top

Secure low pressure hose to victim

Indications for Buddy breathing with Interspiro connections

Victim has an Interspiro SCBA

Victim has an intact facepiece and an operational Interspiro SCBA

Buddy Breathing with Interspiro Connections

Connect the victims low pressure hose to either of your male or female Interspiro quick connect coupling on the low pressure regulator

You can connect to the victims buddy breather port on their right shoulder. It is male connection only

Check connection with a tug

High Pressure Air Supply

Description

Indications

Procedure

High Pressure Air Supply Description

The high pressure hose is 67” long

It is bottle pressure

It is a RIC UAC connection which came from NFPA 1981. You’ll find them on 2002 SCBA models and newer

The High pressure air supply is to partially recharge the depleted air cylinder of a firefighters SCBA

High Pressure Air Supply Description Cont.

The male RIC UAC connection on the SCBA is equipped with a relief valve which will open when the emergency air supply is greater than the maximum pressure rating of the victims air pack

It is for emergency use only

High Pressure Air Supply Indications

A quick fill to aid in a expedient extrication

Everything on the victims pack is intact and working

Know that you are not supplying the victim with the most air possible

When you can’t be attached to the victim with a buddy breathing line or regulator

High Pressure Air Supply Procedure

Fully extend the high pressure hose from it’s storage compartments

Remove the dust cover on the female coupling and the dust cover on the victims air pack

Plug the RIC UAC fitting in to the victims pack

Observe your RIC packs pressure gauge and the victims pressure gauge

High Pressure Air Supply Procedure Cont.

Once both bottles have equalized the air will stop flowing

Disconnect the high pressure supply hose

After charging you may have to repeat this procedure if the victim gets too low on air again

Remote Gauge Console Low Battery

The low battery light will light for 20sec. And then begin to flash slowly at once a second.

The batteries will have sufficient life to operate the LED display longer than the longest duration cylinder

Remote Gauge Console Battery Replacement

Remove both battery caps with a Phillips head screwdriver

The battery closest to gauge is “-” end out

The battery farthest from gauge is “+” end out

When covers are back in position the LED display will light for Approximately 20sec.

Tighten both screws hand tight

Perform operational inspection to verify proper operation of LED display
