DC Flashcards
What are the three types of heat transfer?
Conduction, Convection and Radiation
Which heat transfer is the transfer of heat through an object like metal?
Conduction
Which type of heat transfer is the transfer of heat through a motion of gases or liquids?
Gases are lighter than air and will rise, gases will become hot enough to ignite other fuels in its path
Convection
Which heat transfer is the transfer of heat across a gap? (feel heat without touching the flame)
Radiation
What is spontaneous combustion?
It’s a type of combustion which occurs by self heating, an increase in temperature due to exothermic internal reactions followed by thermal runaway and finally auto ignition.
What is an ALPHA Fire?
A alpha fire is a fire that leaves embers, an ash. Like wood or paper products. It has white grey smoke. Extinguishing agent is water or AFFF. Overhaul method is to break up embers with straight stream water from various nozzle.
What is a BRAVO Fire?
A bravo Fire is a flammable liquids fire. It has black smoke. Preferred extinguishing agent is AFFF, could also use PKP or CO2. The overhaul method is to cool the fuel source.
What is a CHARLIE Fire?
It’s an energized electrical fire (arching and sparking). The smoke is blue in color. Secure the power source. Extinguishing agent is CO2, or water fog from 4’ away with short bursts. Overhaul method is get rid of the electrical item.
What is a DELTA Fire?
A delta fire is combustible metals. The color of smoke varies. Extinguishing method is water in quantity from a safe distance, Sand or jettison over the side. The overhaul method is get rid of the object.
What are the different types of extinguishing agents?
Water, CO2, AFFF, PKP or APC
What is a straight stream of water as an extinguishing agent used for?
Applied to the seat of the fire at a great distance, it cools and breaks up burning material.
What is a narrow angle (30 degree) pattern used for?
Pattern removes heat, water shield for personnel.
What is the wide angle (90 degree ) pattern used for?
Pattern creates a protective shield for firefighters. Too much water creates steam which absorbs heat and displaces oxygen. Don’t put more than 1” on deck, what you put in you need to take out of the space.
What is CO2?
It’s a colorless and odorless has which is heavier than air. CO2 displaces oxygen. It’s stored under pressure in a liquid state, when released it turns into a gas. Doesn’t cool a fire. Can be used as a re-flash watch fire extinguishing agent.
What is AFFF?
It’s a mixture of water (97 percent)and foam (3 percent). Mixed with an inline inductor from a 5 gallon jug or by fixed system. It floats on top of liquid fuels, forms a vapor barrier.
What is PKP?
It’s non toxic, does not prevent a re-flash. It interrupts the chemical chain reaction of the fire. Does not displace O2 or remove heat.
What is APC?
It’s used to extinguish cooking oil and grease fires. It creates a foam barrier. Fixed systems are manually or automatically activated, 42 percent potassium carbonate and 58 percent water.
