What are the differences between a carbon fiber cylinder and a Kevlar cylinder?
Carbon fiber - gray, weigh 17.1 lbs.
Kevlar - yellow, weigh 20.4 lbs.
Describe the conditions that would cause your Vibralert to activate.
Low air (33% or less)
Failure of the primary pressure reducer either open OR closed
When pressurized to 4500 lbs., the 60-minute cylinder contains how many cubic feet of air?
87
Describe the difference between diabetic coma and insulin shock as it pertains to the amount of insulin in a patient.
Coma – not enough insulin or the body is not properly utilizing insulin
Shock – body response to hypoglycemia due to high levels of insulin
What could you do while on scene to assist and comfort the family of a SIDS baby?
Allow the family to grieve in their own way
Be empathetic/understanding
Initiate CPR if requested by family, even if patient is clearly deceased
Do not speculate on cause of death
Learn/use child’s name
Maintain eye contact with family
Acknowledge their feelings
Offer to make calls on their behalf
Ask if they would like to hold the child
Name 5 types of shock and identify the causes associated with each. (NASHCOP)
Neurogenic - high spinal cord injury
Anaphylactic - occurs when a patient reacts quickly to a substance to which they have been sensitized
Septic - a result of severe infections where bacteria damage vessel walls with toxins
Hypovolemic - inadequate amounts of fluid in the circulatory system
Cardiogenic - inadequate pumping of the heart or pump failure
Obstructive - an obstruction that prevents distribution of adequate blood volume
Psychogenic - sudden reaction of the nervous system that produces temporary, generalized vasodilation and syncope
What is the patient criteria regarding the use of the AED?
Pulseless
Over the age of 1
Non-trauma patients
What is the adult “Chain of Survival”? (RIRBAR)
Recognition/activation of EMS
Immediate high quality CPR
Rapid defibrillation
Basic/advanced EMS
ALS and post arrest care
Recovery
What are the potential uses of the Flamefighter nozzle? (CARB CMC)
Confined spaces
Attics
RVs
Basements
Car fires
Mobile homes
Compacted material
Why is it important that a hydrant be utilized in the fully opened position?
If not fully opened, the drain hole will remain open which can cause erosion of the ground around the hydrant.
What types of nozzles are on the transverse bed of your apparatus? What are the GPM settings on these nozzles?
Akron Turbojet fog nozzle - 95, 125, 150, 200, Flush (up to 5/16”)
7/8” Akron Smooth Bore - 161
Describe the process for testing 1 3/4” and 2 1/2” hose.
Connect hoses to test gate valves, fill to 50 PSI, then purge air. Hose length is recorded and couplings marked/checked for leaks. Valves are closed and hose is pumped to 300 PSI (NFPA 1962) for 5 minutes. Lines then bled and couplings checked for slippage. Tag hoses that failed and place out of service, mark hose that passed, record results.
What is Class A foam used for?
Fires involving ordinary combustibles
Wildland fire
You are at a fire scene and need to extend your 1 3/4” transverse hose line. What are your options? (TBACH)
Transverse (other bed)
Bumper load on newer Pierces
Attack packs
Connect 2 1/2” with reducer
Handy folds with reducer
Using the proper double female and double male, can you use a siamese for a wye?
No, because the siamese contains clapper valves and only allows water to flow in one direction (smaller to larger).
How much booster line is carried on TFD pumpers?
200’
What are the characteristics of a good fire stream?
90% of stream within 15” circle or 75% of stream within 10” circle at the breakover point
A stream that is stiff enough to attain height required with a stiff breeze blowing
At what angles are the maximum reaches of horizontal and vertical fire streams achieved?
Horizontal - 32 degrees
Vertical - greatest actual is 90 degrees, greatest practical is 70 - 75 degrees
What are the disadvantages of a fog stream?
Less reach/penetrating power than solid
More susceptible to wind currents
Can create heat inversion when improperly used
What is a disadvantage of an automatic nozzle?
If the nozzle is partially closed (or supply pressure low), it is possible to create a stream that appears effective but is actually not
What is the equation used to determine engine pressure?
Engine Pressure = Nozzle Pressure + Friction Loss +/- Elevation + Appliance Pressure
Describe the placement of ground ladders for the following emergency operations:
A - Rescue
B - Ventilation of a roof
C - Ventilation of a window
A - If size permits, extend 2 - 3 rungs into window, otherwise place at bottom of sill. If victim conscious, set up ladder and then roll into place
B - Extend ladder 5 - 7 feet, or 3 - 5 rungs, above roof or parapet. Minimum 2 ladders required (opposite sides of building)
C - Beside opening with tip of ladder at top of window on upwind side
How often are ladders inspected?
Monthly (quarterly per shift) on Thursday before Saturday inspections
