Trics Of The Trade: Providing Air to a Downed Firefighter

"Mayday, Mayday, Mayday". Ladder One Officer to Command, Mayday" "Command to Ladder One Officer, go ahead with your Mayday" "Ladder One to Command, Mayday, I am lost in the basement and running out of air, I am not sure where I am!" "10-4. Command to...

The low pressure hose is 20 feet long and provides the member monitoring the air supply the opportunity to be far enough away from the extrication area so as not to be an obstacle to the extrication team. He must not only monitor the air supply but also make sure the hose does not become an entanglement hazard, and is not accidentally burned or cut. The low pressure method may be used in any one of the following four ways:

  1. Replacing the member's regulator
    • Disconnect the member's regulator and attach the PAK regulator to the member making sure the regulator locks into position. Listen for the distinct "click" of the inhalation valve indicating that the member is getting air. If this is not heard, turn the purge valve to give the member an air flow, keeping in mind that this will also deplete the air supply faster than normal breathing.
  2. Replace the Hansen fitting from the SCBA with the Hansen fitting from the RIT PAK (see photo 4).
    • Disconnect the Hansen fitting from the members SCBA first, then attach the Hansen fitting from the RIT PAK to the SCBA low pressure hose (see photo 5).
    • We have found in training that it seems easier to disconnect the Hansen fitting by squeezing with one hand and pulling the sleeve back with the other hand (see photo 6). This takes practice, once the fitting is connected, pull to check engagement.
  3. Replace members face piece with the RIT PAK face piece.
    • Remove the members face piece and replace it with the RIT PAK face piece and regulator
    • Check for proper seal and listen for the initial "click" of the inhalation valve. If the inhalation valve does not activate, use the purge valve as mentioned above to supply air to the member.
  4. A fourth method is to use the Schrader Connection.
    • This connection is used by the FDNY to hook the air supply up to an air cart for an uninterrupted supply of air. This method of use works very well if you have the proper fittings. It will give you constant air in an IDLH where immediate removal is not possible (see photos 7 and 8).


If you were to have an incident where a civilian is trapped in an IDLH, the procedure used in my department calls for an additional unit to respond with a RIT PAK. The original RIT unit is to keep the RIT PAK in reserve for members only. The RIT PAK should be checked daily when checking you regular SCBA and cleaned the same also.

As I stated earlier, we are not discussing the actions of a RIT, we are talking about another tool for your box. This tool could mean the difference between one of us surviving or sucumming to the by products of combustion. In photo 9, the RIT PAK is in its carry case and ready to go. In photos 10, 11, and 12 you can see the way the RIT PAK is put together. You must keep oriented and know the position of the PAK at all times. The arrow in photo 9 points to the pocket that holds the UAC. We put a handle on this to make it easier to identify in zero visibility. It is imperative that if you have one of these tools on your apparatus, you must drill on it over and over until you are proficient to the point of rote motion. Not only do the brothers or sisters lives depend on it, if you can't use it and someone dies, how is your life going to be when you reflect on that moment in time.

The RIT PAK, another tool for your box, another Tric of the Trade.
