SCBA Add. 4 (Rebreather) Extended duration SCBA Flashcards
The Extended Duration SCBA (EDSCBA) will provide up to how many hours of breathable air?
1.3
The EDSCBA will provide the wearer with up to four hours of breathable air, a significant increase over current SCBAs.
The air supply in an EDSCBA is heated by the user’s breath and by the scrubbing process
used to filter the air. Due to both these factors, the air requires cooling before it is recirculated. The cooling process is accomplished by passing the airflow over a block of ice that is installed in the unit immediately prior to use. If the air were not cooled,
it would still be safe to breathe, but the increased air temperature would make it uncomfortable for the wearer. At what temperature should the ice not be used?
.
2.3
The addition of the ice block is only required at ambient temperatures above 32 degrees
Fahrenheit. At temperatures below 32 degrees Fahrenheit, the ice block should not be used
The prolonged “on air” time provided by the EDSCBA is an asset when dealing with fire and emergency operations in areas such as confined spaces, under river tunnels, sub-cellars, below-deck areas of ships, etc. Can they be used at routine structural fires?
1.4 & 1.7
EDSCBAs are not designed for routine structural firefighting or for underwater operations.
The Entry team leader of an EDSCBA operation shall consist of whom?
5.1
Shall consist of an EDSCBA trained Battalion Chief and Battalion Firefighter, preferably the Rescue Operations Battalion.
Operational Units - shall perform assigned tasks such as firefighting, search, victim removal, under the supervision of?
5.2
The Entry Team Leader.
The Support Unit shall accompany the Operational Units to the vicinity of the operation, and provide them with the needed equipment. They shall then
withdraw from the immediate proximity of the operation to a location that if possible, provides an area free from immediate hazards, and provide what?
5.3.1
The Support Unit shall serve as the communications link, relaying communications between the Entry Team Leader, operating units, and the Command Post as needed. The Support Unit will be “on air” along with the operating units, and must not engage in any activities that would tax their air supply.
Due to the hazardous environment and prolonged operational time expected, a Safety Management Team (SMT) shall be established prior to any entry with EDSCBAs.The Safety Management Team shall predetermine the duration of operations using EDSCBA prior to entry. Operational plans shall not exceed how much time?
6.1.3
3 hours 30 minutes, allowing sufficient exit time for the entry team to reach fresh air.
The EDSCBA has a warning alarm on the mask that operates when approximately __ minutes of operational time remains.
Fill in the blank
6.1.4
60 minutes
.
The FAST Unit shall accompany the operational units to the vicinity of the operation to obtain a size-up of conditions confronting the units; they shall
then immediately do what?
6.2.1
Withdraw to the safe location identified by the Support Unit. The FAST Unit shall monitor handie-talkie communications for Urgent or Mayday messages, and prepare to deploy if necessary. The FAST Unit will be “on air” along with the operating units, and must not engage in any activities that
would tax their air supply.
Outside Standby Team - if the entry will involve a deep penetration and large logistical support, how many Rebreather trained companies shall be maintained in reserve?
6.3
Two additional Rebreather trained companies should be maintained in reserve at the point of entry with operational EDSCBAs.
Incidents in tunnels, ships and other large areas can pose serious communication difficulties. The primary means of communications with the entry team will be?
7.1
Post Radios in the vicinity of the operations site (staffed by a member of the Support Unit) and exit point (staffed by a member of the Safety Management Team).
