SCBA Flashcards
What is a toxic product of combustion that can be deadly at high levels? At low concentrations, it can go undetected and contribute to nagging illness.
Carbon monoxide (CO)
leading cause of accidental death in the U.S.
Carbon monoxide (CO)
Number of Carbon monoxide (CO) deaths and illnesses
1500 accidental deaths and 10,000 illnesses annually.
Carbon monoxide is a ____, ____, and ____ gas that is a common industrial
hazard.
Colorless, odorless, tasteless
carbon monoxide poisoning symptoms
Mild poisoning can cause such symptoms as nausea, dizziness or headaches, while
severe poisoning can result in brain damage, heart damage, and even death.
Be suspicious of carbon monoxide poisoning if you develop headache, flushed face,
dizziness or weakness.
What PSI for hydro testing
50 psi
What are the psi’s for full, 3/4, 1/2, and 1/4 of the bottle
Full = 4500
¾ = 3375
½ = 2250
¼ = 1125
Type 1 Engine & Trucks
4 SCBA, 8cyl., 1 mask, 1 reg.
1 Hour Bottles IN RIC packs (Trucks & Rescues)
Type 3 Engine number of SCBA’s, Regulators, Cylinders, and Masks
3 SCBA, 3 reg, 6cyl (30min), 1 mask
When does the Vibralert LOW pressure ALARM kick on?
At 1125 (25%) 135psi (2nd) piston kicks on.
Purge valve
0-125 LPM
When to Wear YOUR SCBA?
Anytime visible smoke is in the structure
Whenever there is a potential for your atmosphere to change
Blown in Insulation
Wear it till the IC determines otherwise
HazMat-Use outlined in CFR1910.120
Confined Space
All Vehicle Fires
Investigators APR’s
SCBA out of Service
Notify your company officer
Tag and route: who, what, when, where
Cylinders needing Hydro drain to 50psi
Repair drain empty
What is a full bottles PSI?
4500 regardless of size
Pressure Reducer Stages
2 Stage Pistons
1st @100 psi
2nd @ 135 psi
Lights indicate a range
Two green rectangular lights = between full and ¾
One green rectangular light = between ¾ and ½
One amber rectangular light = between ½ and ¼
One blinking rectangular red = less than ¼ left
Add __ degrees for bunker gear
10
Fill SCBA at what PSI per/min
1500 psi per/min
STAYING HEALTHY:
HYDRATION, NUTRITION AND SLEEP
DANGERS OF OVEREXERTION
MYOCARDIAL INFARCTION/CARDIAC ARREST
RHABDOMYOLYSIS
LIGHT WORKLOAD:
COMFORTABLE,
LITTLE TO MINIMAL SWEAT
NORMAL BREATHING AND PULSE
MODERATE WORKLOAD:
SOME SWEATING,
HR 80-100
MAY BE SLIGHTLY WINDED.
HEAVY WORKLOAD:
ACTIVE SWEATING,
HR USUALLY > 100-120,
WINDED, USUALLY LESS THAN 5 WORD SENTENCES
HYDRATION:
HEAVY WORKLOAD
DRINK SPORTS DRINKS WITH ELECTROLYTES FOR HEAVY WORKLOAD
AVOID CAFFEINE ALTOGETHER WHEN HYDRATING FOR HEAVY WORKLOADS.
HEAVIER EXERTION/TRAINING INCREASES PERSPIRATION AND SALT LOSS.
OVER CORRECTION BY DRINKING PLAIN WATER CAN CAUSE LOW SODIUM- (HYPONATREMIA)
Best Practice per CDC- PREHYDRATE FOR HEAVY WORK WITH 16 OZ SPORTS DRINK THEN
MAINTAIN WITH 8 OZ PER 20 MINUTES OF HEAVY WORK. OPTIMUM LEVELS OF CALORIES,
POTASSIUM AND SODIUM ARE IMPORTANT.
HIGH PROTEIN/FAT DIETS ARE
HARD ON KIDNEYS
REDUCE TOTAL BODY WATER (DEHYDRATING)
SALT IN MODERATION IS GENERALLY GOOD, NO LESS THAN…
2000 MG/DAY
AVOID:
ALCOHOL
TOBACCO
ENERGY DRINKS
STIMULANTS, HERBAL REMEDIES ETC.
EXCESSIVE WATER
All Hazard Response
BOMB THREAT
EARTHQUAKES
FIRE & EXPLOSION
MEDICAL EMERGENCIES
SHELTER IN PLACE
WORKPLACE VIOLANCE
How often do bottles get hydrostatic tested?
5 years
How long do bottles live?
15 years
