CFD SCBA and Fill Stations Flashcards
SCBA air management - reserve air
FF should not use their reserve air (final 33% or 1575psi) for completing task or exiting the hazardous atmosphere
This reserve air is for emergency use only
BOA
Breathe, organize, act
is helpful in reducing the mental and physical reactions that can occur
four breathing techniques
skip breathing
box breathing
the reilly emergency breathing technique (hum)
straw breathing
Emergency breathing - wheel breathing
can be done in low air situations or in the event of a severed or cut air supply line
technique is done by shutting the cylinder off at the handwheel and turning it on to get a breath then turning it back off
heat stress
heat cramps
heat exhaustion
heat stroke
Heat cramps
least severe and can be treated with rest and fluids
heat exhaustion
more severe and often present similar symptoms to heat stroke
dehydration and hypovolemia
heat stroke
very serious medical condition
dehydration and inability to sweat
MSA G1
is an open-circuit, pressure-demand self-contained breathing apparatus
Personal alert safety system (PASS)
provides the user with the ability to monitor movement through motion sensors (also monitors cylinder pressure and battery status)
full alarm
motionless for 30 seconds
pre alarm
motionless for 20 seconds
Facepiece
available in 3 sizes

500 degrees Fahrenheit
regulator
pressure-demand regulator which maintains positive pressure in the facepiece while the SCBA is in use
push to connect connection, equipped with an emergency bypass valve
Left side of HUD
status icon
evacuation icon
low batter icon
right side of HUD
air level indicator
primary low pressure warning device
alarms when there is approx. 35% of the SCBA rated service time remaining and when the cylinder valve is first opened
power module
serves as the power supply and provides all of the information for the control module, regulator and speaker module
has 4 buddy lights
pressure reducer
reduces the pressure from 4500 psi to 102-113psi
Integrated TIC
hold either green button for 3 seconds to activate/deactivate TIC
TIC colour pallets

black hot
white hot
red hot
rainbow
iron bow
fire and ice
Buddy lights
7 in total - are viewable 360 degrees
three stage colour coding (green, yellow, red)
buddy light on regulator only has two colours (yellow and red)
backplate
D rings on each side are rated to 500lbs and the top ring is rated to 1000lbs
quick fill pouch
right side
contains a 3 foot (.75m) hose
Three functional safety tests
A- regulator and facepiece can hold negative pressure
B- test the function of regulator and speaker module
C- test the function of power module, control module, primary low pressure warning device and HUD
three pre entry safety checks (must be done in this order)
tug test
bypass
negative pressure
HUD pressure status
HUD Alarm status
HUD alarm status - three icons
battery icon
running man icon
caution triangle
start up sequence - primary screen
go icon
maintenance
do not use
“Go” icon - start up sequence
successful self test will display a go icon to indicate the unit can be put into service
Maintenance Icon - start up sequence
if maintenance is required, a maintenance icon will appear indicating the unit should be removed from service after use
Do not use icon - start up sequence
if the device should not be used, a do not use icon will display on the control module and the full alarm from the power module will be alarmed
colour background
green indicates 50% or higher
yellow indicates 36-49%
Red indicates lower than 35%
thermal alarm
is the user is exposed to more than the pre-set limit of thermal load, the secondary alarm on the control module will display and the power module will sound a tone every 5 seconds
secondary screen displays
temperature icon
short range radio icon
long range radio icon
battery icon
time remaining calculation
secondary screen displays image
green reset buttons - single press
activate the backlight and refresh the HUD
toggle between primary and secondary screen
green reset buttons - double press
reset PASS pre-alarm (or shake)
Reset PASS full alarm
confirm evacuations
turn off device (when below 200 psi)
clear primary alarms
Alarm button (red)
activate PASS full alarm by pressing and holding the alarm button, will occur if unit is on or off
facepiece cleaning
use Ecolab neutral disinfectant cleaner
let solution remain on facepiece and nose cup for a minimum of 10 minutes
back frame and harness cleaning
use soapy water
when cleaning regulator
To clean the regulator, ensure SCBA cylinder is attached and open to pressurize the system, immerse the regulator in the Ecolab® Neutral Disinfectant Cleaner (wash bucket) and agitate it. Rinse the regulator by agitating it in a sink of clean, warm water.
Shake the regulator to remove excess water. With air turned on, open the bypass until all mist has disappeared. Dry with lint free cloth (Wypall X60) and replace the rubber cover.
cylinder storage
for maximum safety, the cylinders should be stored full or at a pressure above ambient but less than 100psi
charger lights
red - charging
flashing green - charging
green - fully charged
Rechargeable Lithium Ion Battery
Recharge batteries at 60% or at start of each Day shift; audible tone is emitted every 30sec; the Control Module displays an empty battery icon; and a YELLOW LED flashes on the HUD
6-bank recharger station will NOT overcharge batteries
Before filling a cylinder, a visual inspection must be performed
Any damaged or outdated air cylinders must not be filled and should be taken out of service, tagged and sent to equipment and supply for repairs and inspection by a certified technician
Cylinder damage - level one
Minor abrasions, scuffs, cuts or scratches resin to the exterior coating are acceptable
Cylinder damage - level two
Abrasions that penetrate partially or completely through the outer glass fiver layer must be repaired by a qualified technician using epoxy to reseal the fibers
Cylinder damage - level 3
If the damage penetrates completely through the outer fibreglass layers to the carbon fibers or to the aluminum cylinder shell the cylinder must be condemned
Cylinder serial number 45 minute
Serial number is 3-letters followed by a 6-digit
Cylinder serial number 60 minute
Serial number is 3-letters followed by a 5-digit
Hydrostatic test date
Insert the most recent test date
If older than 5-years or unreadable do not fill the cylinder, tag it and send it in for service
Cascade
When filling from the cascade system with out compressor operating
Boost
When filling from the compressor operating in boost mode
Shoreline
When filling from the compressor when running only on electricity
Diesel
When filling from the compressor with diesel motor running and from the surrounding atmosphere
CFD training academy
Wind is from the east to southeast
Greater than 15 knots
Tower or burn pans are active
Air intake might be exposed to higher than normal levels of contaminants
SCUBA cylinders cannot be filled
the vehicle and maintenance facility
Training academy
What psi when filling escape cylinders and SCUBA cylinders
3000psi
Hot fill
If a cylinder is filled too fast (more than 300psi per min) you will not achieve maximum fill capacity
fill station log books
tag colours
