Next Question

• Process of creating gasses from a solid is called ______. Process of creating gasses from a liquid is called ________.

• Pyrolosis and Vaporization

Next Question

• What two characteristics of a solid will influence the rate of fire spread

• Surface to mass ratio and vertical positioning

Next Question

• State the law of conservation of of mass

• Mass and energy may be converted from one to another, but there is never any net loss of total mass energy

Next Question

• List the components of the fire triangle

• Heat, Fuel and Oxygen

Next Question

• List the parts of the fire tetrahedron

• Fuel, Heat, Oxygen, Uninhibited Chemical Chain Reaction

Next Question

• List, and define 3 of the phases of fire

• Incipient, Free Burning, Hot Smoldering, Roll Over, Flashover

Next Question

• List 3 characteristics of a potential backdraft

• Puffing Smoke, minimal flame, dense gray yellow smoke, “moaning” sounds coming from the building, smoke stained windows

Next Question

• Define thermal layering and its impact on interior fire attack

• Layers of heat in a building, hottest at the top. Can become upset by improper water application and improper ventilation

Next Question

• Provide 2 examples of class A fire and 2 examples of a class B fire

• A = Normal Combustable (Ash), B = Flammable Liquids (Boiling)

Next Question

• Water extinguishers are designed to eliminate what part of the fire tetrahedron

• Heat – Note: foam is often added to help break surface tension of water to help it penetrate better.

Next Question

• According to the Fire Tetrahedron, what is the most effective method for extinguishing a Class B fire?

• Excluding the Oxygen

Next Question

• What is the safest way to handle a Class C fire

• Deenergize the source and treat as a class A or B

Next Question

• What class of fire extinguisher is rated based on effectiveness when used by a non expert?

• Class B

Next Question

• Which of the following is NOT part of your turnout gear

• Helmet

• Turnout coat and bunker pants

• Pocket spanner wrench

• SCBA

• Pocket spanner wrench

Next Question

• You are part of an interior attack team and your face shield begins to melt. What does that mean to you?

• Very hot, Very dangerous. They will melt between 250 and 300 degrees

Next Question

• Turn out coats are made of how many layers?

• 3 as required by NFPA 1971

• An outer shell

• Moisture barrier

• Thermal barrier

Next Question

• Is there any safety difference between a dirty turnout coat and a clean turnout coat?

• Dirt absorbs heat faster than the turnout coat subjecting the wearer to higher heat conditions.

Next Question

• Reflective trim should be positioned where on turnout coat, and how wide should it be?

• Should encircle the sleeves and hem of the coat and should be 2 inches wide.

Next Question

Round 2

• What set of letters is used to help people remember how to use an extinguisher, and what does each letter mean?

• P- pull, A- Aim, S- Squeeze, S- Sweep

Next Question

• What are the shapes and colors for ABC and D fire extinguishers

• A- Green Triangle, B – Red Box, C – Blue Circle, D – Yellow star

Next Question

• What type of extinguisher might you use on computer equipment

• Halon or CO2

Next Question

• When using an extinguisher, where should the stream be directed

• At the base of the flames

Next Question

• What is the difference between dry chemical extinguishers and dry power extinguishers

• Dry chemical ABC or BC, Dry Power D only

Next Question

• Open Circuit and Closed Circuit are the two different types of SCBA’s. What is the major difference, and which is used more if fire service?

• Differences

• Closed – compressed or liquid oxygen (also rebreather)

• Open – compressed air

• Open is used more often

Next Question

• What is the benefit of a positive pressure SCBA?

• Positive pressure prevents contaminants from entering facepieces if a leak develops

Next Question

• List three ways to prevent/correct internal fogging of your SCBA mask

• Nosecup, anti-fog chemical, briefly turn on the bypass valve
