Demonstrate:
1. Why SCBA is necessary?
2. What are limitations – equipment ,
environment and user?
3. Maintence & Use

BUCKLEY FIRE
The ONLY Approved
Respiratory Equipment:
MSA FireHawk SCBA
& N95
SCBA Mandatory use
1.All Fire Department Personnel shall wear
SCBA when operating in any of the following
atmospheres.
a. Any IDLH atmosphere.
b. An oxygen rich or deficient atmosphere.
(Under 19.5%, Over 23.5% oxygen)
c. An atmosphere of particulate, gas or
vapor contaminants. ie: asbestos, CO,
HCN
SCBA Mandatory use
d. In any permit-required confined space
that has not been tested and monitored
to establish respiratory safety.
e. Any possible signs of WMD event.
Gross Decon shall be performed prior
to removal of face piece.
SCBA Mandatory use
2. SCBA shall be used by all personnel who
enter into hazardous atmospheres during
structural firefighting activities or other
IDLH or potential IDLH atmospheres,
including:
a. In an active fire area.
b. Directly above a fire area.
(vertical ventilation)
c. Directly under the active area.
d. In potential explosive or fire area,
including gas leaks or fuel spills.
SCBA Mandatory use
e. Where products of combustion are visible in an
atmosphere, including vehicle fires and
dumpster fires.
f. Where invisible contaminants are present or
suspected. This includes the overhaul stage
of a fire.
g. Where toxic products are present, suspected of
being present, or may be released without
prior warning.
h. In an active chemical spill area where the
chemical presents an inhalation hazard.
SCBA Mandatory use
• SCBA use is mandatory if you are
working in atmospheres where CO, HCN
and other toxic gasses are suspected to
be above safe levels.
• Fiberglass dust and other particles in the
air, or suspected in the air, require SCBA
use.
N95
When transporting an individual with
suspected or confirmed infectious
tuberculosis or meningococcal bacterium
or other infectious air borne illness,
(H5N1, H1N1) even if individual is masked.
Not used for overhaul.
Hazardous atmospheres members
may be exposed to during Routine
and Emergency Operations:
• Oxygen deficient
• Aerosols
• Gaseous
• Elevated temperatures
• Flashover
• Irritant particles
• Toxic gases
•Unknown
•Overhaul operations
Cleaning the SCBA
•
•
•
Keep water
out of 2nd
stage
regulator.
Use brush,
check bell
for sheet
rock.
Hang to air
dry.
Cleaning the Face Piece
1.
2.
3.
4.
Remove voice amp before starting
Water temperature below 120 degrees
Rinse large debris off with water
Wash with MSA disinfectant wipes
provided at station (no alcohol on
facepiece)
5. Confidence Plus- ½ oz in a gallon of
water or use spray bottle of Spirit II.
6. Rinse with water
7. Towel and AIR DRY- hung upside down.
User Limitations
• Physical condition – maximize work
effort
• Agility – restrictive movements
• Facial Features – seal issues
• Contact Lenses – otherwise glasses
inserts are provided
• Respiratory – any smokers?
• Mental – training, confidence, “cool”
Equipment Limitations
• Limited visibility – peripheral vision is
reduced, fogging
• Communication – failures of lapel mics,
amplifiers not turned on.
• Weight – 25-35 extra pounds
• Mobility – backpack and straps reduce
ability to move freely
• Equipment malfunction – Know what to
do if your equipment suddenly
malfunctions
Environmental Limitations
• Cold Weather – water spray from fire
fighting activities can cause SCBA to freeze
up and not function properly.
• Chemicals – while the SCBA protects your
respiratory system, many chemicals are
absorbed through your skin. DECON.
• Extreme Heat – Elevated temperatures
such as flashover may damage SCBA
beyond use.
Air Supply Limitations
• “30 minute” bottle = 45 cubic feet, 20 – 25
minutes working time (or less).
• “45 minute” bottle = 66 cubic feet, less than
40 minutes working time.
• “1 hour” bottle = 88 cubic feet, less than 45
minutes working time.
AIR CYLINDER
Level 1 damage:
OK to continue using.
Level 2 damage:
Circle damage with permanent
marker and send in for repair.
Level 3 damage:
Not repairable.
Must be taken out of service.
FIRST STAGE REGULATOR
Audi-larm
• Audi-Larm Rings at 25% of service
pressure remaining - approximately 550
psi
• O-ring must be seated at connection
from cylinder to coupling nut. Daily
check!
Second
Stage
Regulator
Carrier and
Harness
URC
Universal Rescue Connections
Buckley has
chest URC.
SCBA made after 2002
have URC 4 inches
from the cylinder
valve.
PASS device
Analog
Digital
All Gauges should read within 5% of each other.
Place out-of-service if difference is +/- 110 psi.
Emergency Operations
Buddy Breathing
vs. Transfill.
Buddy Breathing
is sharing a
regulator.
Note: Offset
placement of
regulator to mask
Transfilling uses hose or RIT/RIC kit to URC to
equalize the pressures of both cylinders.
RIT/RIC Kit
•
•
•
•
•
Each engine has a RIT/RIC kit
3 or 6 foot trans-fill hose
Mask is attached to 2nd stage regulator
May crack open bypass for unconscious
It is normal to have a slight positive
pressure to the mask when bottle is
turned on.
Setup is exactly
the same on each
engine.
Time for a quiz…
Then go Donn some SCBA!!!
