Confined Space Rescue is one of our agencies specialties. We fill 2 teams of 2 fully equipped (enrty team and backup team).
ENTRY OFFICER: Reports to the Extrication Officer. Is directly responsible for the operations of entry and back-up teams, communications with said teams, and operations within the space. This person will be operating the Con-Space (brand) communications system. The system consists of main box which has 4 outlets, a splitter box, which allows communications with both teams simultaneously or one team at a time. A speaker box, a headset, and assorted cable lengths. Also must ensure proper PAS proceedures are followed.
ENTRY TEAM: Is responsible for entry after hazards mitigated and air quailty on exterior is sampled and recorded. Entry team WILL have on nomex jumpsiut, Steel toe boots, Bullard Advent helmet, rope rescue style gloves, nomex hood, knee and elbow pads if preferred, full body harness (class 3 NFPA 1983 approved),Cairns Pioneer SABA with 15 min escape bottles (or SCBA 45 minute bottle with in line air port), PASS device, wrists and ankles duct taped, hi intensity white lightstick for visibility in IDLH atmsphere, and Con Space (brand) communications equipment. This includes a throat mic and ear receiver.
They are attached to an "umbilical" which is simply a 2" piece of 100' webbing. Inside the webbing the supplied air hose, 7/16" lifeline, and hard wire communications cable are fitted. This makes line managment simple and easy. The entry team had one red umbilical and one blue one. This helps to distinguish the 2 members. There are (4) each red and blue so that each member may have 200' of line. Air is supplied by Air Systems Intl Pack4 carts with 60 min air cylinders.
The duty of this team is to enter the safed space and determine the mechanisim(s) of entrappment / engulfment, access and other factors. They are responsible to bring a supply of air to the victim, this is accomplished by bringing a "victim bag" into the space. Such bag comtains a simple full face mask and strap to hold it on the victim and 200' of air supply line. They are also responsible to provide the device (s) required to remoe the patient. This is usually goung to be one of several things including but not limited to a SKED, 1/2 SKED, LSP halfback or Wristlets. It is ideal to treat injuries that present as severe and try to preserve spinal stability, but also understood that such may be impossible to do in the space given.
BACK UP TEAM: Equipped identically to entry team. Stands by to assist in rescue of primary team if needed and to serve as second entry team. At no time will the back up team enter the space without another team filling their vacated position. Back up team may also provide air quality sampling periodically thrpughout the incident or assist with other tasks which won't distract them from their main duty.
Retrieval system is uaually a Hercules adjustable tripod (6-10' i believe) with a pre rigged 4:1 system of 1/2 inch rope. A ladder derrick may also be used as well as an aerial device if need be.
Atmospheric ventilation is accomplisned with an Air Systems blower, it has a 20' and 10' flex duct and saddle vent tube for manhole apps. Also have available a 16" smoke ejector with 25' flex duct.
Air monitoring accomplished with AIM 4 gas detectors, set up with oxygen, carbon monoxide, LEL, and Hydrogen sulfide sensors.
