SCOTT RIT-PAC III

Objectives  Describe the SCOTT RIT-PAC III and it’s components  Daily check and inspection  Basic Operation  List and describe the options you have with the low pressure side of the pack  Describe and go over the procedures of the high pressure side of the pack  The procedure for changing the Remote Pressure Gauge batteries

Description Definition-Portable air supply intended for use by a Rapid Intervention Team as an emergency source of breathing air to supply a single down Firefighter while that person is being extricated from a IDLH atmosphere.

The Bag  T-Handle is on the high pressure side of the bag  Ball-Handle is on the low pressure side of the bag  Dedicated rigid compartments to store the High and Low pressure supply hoses  The top cover has two additional soft storage compartments  The skid plate protects the bottom and sides of the bag

High/Low Pressure Lines  Low Pressure Hose is 6’ Long  The low pressure manifold has male and female quick connect couplings for Scott and Interspiro  High Pressure Hose is 5’ long  The high pressure hose has a Rapid Intervention Crew Universal Air Connection (RIC UAC) fitting.

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
