What is the max service life of a cylinder?
15 years
According to the E & M manual, 1 3/4” hose is tested annually at ___ PSI for ___ minutes.
300, 5
5” hose is tested annually at ___ PSI.
200
A 100’ section of 5” hose has 3 markings on it. What are these markings and where can they be found?
Single white stripe at 25’ and 75’
Double white stripe at 50’
Constant Gallonage Nozzle
Will flow constant amount of water regardless of stream shape
Does so through a selector ring that increases/decreases size of discharge orifice
Automatic (Variable) Gallonage
Increase in pressure increases orifice size, allowing more volume (deflector moves out as pressure is increased)
Smooth Bore Nozzle
Fixed orifice and single pattern
According to IFSTA, a fire stream is identified by its size and type. Size refers to ___ and type refers to ___.
Volume (GPM), pattern/shape
List 2 ways to reduce friction loss. (SIRUM)
Shorten hose lay Increase hose diameter Reduce kinks Use smaller tip More lines
The tip of a smooth bore nozzle should be no larger than:
1/2 the diameter of the hose
Ladder weight limits:
Folding - ___ lbs.
Straight/roof - ___ lbs.
Extension - ___ lbs.
300
750
750
When moving or removing a ladder that was previously placed by someone else, it is first necessary to:
Coordinate with those who originally placed the ladder.
A ladder with a working height of 16’ should be ___’ away from the wall at the bottom.
4
Name 3 locations to avoid when placing ladders, according to the E & P manual. (HOBI)
Horizontal openings
Overhead obstacles
Blocking access to the fire structure
Immediate area of involvement
Give three reasons for ventilation, according to IFSTA.
Life safety Speed of fire attack Fire spread control Reduction of flashover/backdraft potential Property conservation
Backdraft is best prevented by using ___ ventilation.
Vertical
Describe positive pressure ventilation.
It uses a high-volume fan to create a slightly higher pressure inside the building than outside.
An important, general ventilation consideration is that:
A rectangular opening is easier to cut and then repair after the fire.
What is the “Emergency Radio Traffic” signal and when is it used?
It is a background tone that is audible anytime someone is transmitting. It is used whenever the air needs to stay clear of non-emergency traffic.
What tools are paired together to make the “irons”?
Halligan bar and flathead axe
What are the 4 types of blades used with circular saws?
Wood cutting
Metal cutting
Masonry
Rescue blade
According to the E & P manual, power extrication tools will perform what 3 basic functions?
Spreading
Compression
Cutting/shearing
What are the 4 components of the fire tetrahedron? (OHFUCCR)
Fuel
Heat
Oxygen
Uninhibited chemical chain reaction
Name the 5 classifications of fire.
Class A - Ordinary combustibles Class B - Flammable/combustible liquids and gases Class C - Energized electrical Class D - Flammable metals Class K - Cooking oils/greases
On TFD, Microblaze is added to pressurized water extinguishers for use on hydrocarbon spills and works by:
Breaking down hydrocarbons into harmless by-products reducing environmental hazards. The cost of disposing of the hazardous waste is reduced compared with shipping and incineration of the contaminated absorbing agents.
CO2 extinguishers should be recharged at what percent of weight loss?
10
The 3 extinguishers carried on TFD apparatus are:
Pressurized water
Carbon Dioxide
ABC Dry Chemical
CO2 is stored in the cylinder as a ___ and converts to a ___ when discharged.
Liquid, gas
A water extinguisher with a “2A” rating contains ___ gallons of water.
2 1/2
Static kernmantle rope used by TFD is ___” in diameter and has a maximum working load of ___ lbs.
1/2, 600
Name the 7 types of rope damage. (HUHCASH)
Heat fusion UV rays Heat Chemical Abrasion Shock loading Heat friction
The family of eights reduce tensile strength by ___%.
20
What are the 3 physical states of matter?
Solid
Liquid
Gas
During the ___ search, be sure to check the known or likely locations of victims as quickly as conditions allow.
Primary
The ___ search is conducted after the fire is under control and the greatest hazards have been controlled.
Secondary
The secondary search should be conducted by personnel other than those who conducted the ___ search.
Primary
List the 3 stages of fire and the danger associated with each.
Incipient - rollover
Free burning/growth - flashover
Smoldering - backdraft
The type of shock resulting from the loss of blood or fluid is known as:
Hypovolemic shock
OPQRST stands for:
Onset Provocation/palliation Quality Radiation Severity Time
With a venous bleed, blood ___ from the wound and is ___ in color.
Oozes, dark red
With a arterial bleed, blood ___ from the wound and is ___ in color.
Spurts, bright red
