TRCS Flashcards
What do you do when you have a rapid loss of pressure in the TRC?
- Add to maintain.
- Check shut all exhausts.
- Shut gag valve if lifted.
- Off bibs, then shut bibs exhaust.
- Check EQ valves in TRCS doors.
How often is a pressure test conducted?
After initial installation, after every major overhaul, and every two years.
What do you do when you have an increase of pressure?
- Off BIBs.
- EXHAUST to maintain.
- Check shut pri/sec drive.
- Shut CO2 scrubber.
- Shut air & O2 hull stops.
What do you do if you have a contaminated atmosphere?
- On air BIBs.
- Switch to secondary.
- Hurricane vent.
* TRC switch CO2 Scrubber to Sec air.
What do you do if there is a fire in the TRCS?
- SECURE O2!!!
- Extinguish fire.
- On air BIBs.
- Hurricane vent.
What do you do if you have a loss of O2?
- Off BIBs.
- Inside Tender check QDs.
- Switch to sec O2.
- Check 75psi on O2 regs.
*** 2hr interruption : switch to comparable air table.
What do you do when you have a loss of primary air in the TRC?
- Switch the T.
2. Add to maintain w/ secondary.
What happens when you have a loss of TL primary air?
- Dial secondary to 200psi.
2. Back off primary air.
What is the operating and max pressures of the TRCS?
Operating: 100PSI
Max: 110PSI
What types of materials aren’t allowed in the chamber?
Wood(shelves, benches, deck plates)
Unauthorized Electronics
Bedding, other than authorized for chamber use.
Wool or Synthetics
Static Electricity Hazards
Any excess bedding, clothing, etc. that could create an unnessisary static or fire hazard.
What are the contents of the primary medical kit, and where is it located during chamber operations?
The primary medical kit contains diagnostic and therapeutic equipment that needs to be available to the IT immediately. It is located in the chamber at all times during chamber operation.
What are the contents of the secondary medical kit, and where is it located during operation?
The secondary medical kit contains emergency treatment equipment and secondary survey equipment, as well medicines to provide ancillary care in support of advanced cardiac life support. It is kept outside the chamber in a visible and easily accessible location.
When do the contents of a medical kit need to be sterilized?
Prior to being added to the medical kit, and after being put under pressure.
What is the purpose of a recompression chamber?
Used for the treatment of DCS and AGE, the administration of Surface Decompression (SurD) and Candidate Pressure Tests, and chambers equipped with an O2 system may be used to administer therapeutic Hyperbaric treatment (TT9).
What are the minimum Primary and Secondary air requirements for navy Chambers?
TRC Mod. 0, a category D chamber, requires sufficient air to press the inner lock twice and the outer lock once to 165FSW is required from primary, including enough air to operate the CO2 scrubber. Secondary requires enough air to press the inner lock and outer lock once to 165FSW and enough air to have one tender and two patients breathe air BIBs for an entire TT6A with Max Extentions. [Ch. 21, Table 21-3]
What are the six things you never want to do in the chamber?
Never shorten tables, never use O2 deeper than 60FSW, never fail to treat doubtful cases, never interrupt chest compressions for more than 10 seconds when applicable, And never let chamber personnel assume a cramped position in the chamber, and never operate over 104 degrees
What are the five parts of a PSOB?
- System certification letter
- Correspondence
- System Calculations
- OPs
- EPs
What is the TRC O2 primary supply?
2 3000PSI flasks with .926FT3 floodable volume, with a useable scf of 369. [TRCS PSOB]
What defines a category D chamber?
- Air Bibs
- OB Dump
- CO2 Scrubber
- Environmental Monitors
What defines the three levels of chamber?
I - 5 min from dive site.
II - 1hr from dive site.
III - 6hr from dive site.
How many gag valves are there on the TRCS?
2 - 1 for TRC, 1 for TL
3 purposes of recompression?
- Crush the bubble.
- Allow time for resorption.
- Supply increased ppO2 to damaged tissue.
What are the temperature limitations for US Navy Chambers?
Over 104 degrees- none.
95-104 degrees- TT5, TT9
85-94 degrees- TT5, TT6, TT6A, TT1A, TT9
Under 84 degrees- all.
Allowable O2 in the Chamber?
19-25%
