Section A Pt. 1 Flashcards
The temperature at which a liquid fuel will produce vapors sufficient to support continuous combustion once ignited.
Fire Point
Heat may be transferred from one body to another by direct contact of the two bodies or by an intervening heat-conducting medium.
Conduction
The minimum temperature at which a liquid fuel gives off sufficient vapors to form an ignitable mixture with the air near the surface.
Flash Point
The transfer of heat by the movement of air or liquid.
Convection
Occurs when an oxygen-starved fire in an enclosure suddenly gets enough oxygen under conditions that will cause an explosion.
Backdraft
The systematic removal and replacement of heated air, smoke, and gases from a structure with cooler air.
Ventilation
Fires involving ordinary combustible materials such as wood, cloth, paper, rubber, and many plastics.
Class A Fires
Fires involving flammable and combustible liquids and gases such as gasoline, oil, lacquers, paints, mineral spirits, and alcohols.
Class B Fires
Fires involving energized electrical equipment such as household appliances, computers, transformers and overhead transmission lines.
Class C Fires
Fires that involve combustible metals such as aluminum, magnesium, titanium, zirconium, sodium, and potassium.
Class D Fires
When rescuing victims from collapsed buildings firefighters prevent further collapse of the building by using ____ , a process of erecting a series of timbers or jacks to strengthen a
wall or to prevent further collapse.
Shoring
When used in fire service terms, ____ is the velocity of water in a conduit (either pipe or hose) of a certain size. ____ , in the fire service sense, is measured in pounds per square inch (psi).
Pressure
The part of total pressure that is lost while forcing water through pipe, fittings, firehose, and adapters.
Friction Loss
Consists of the search for and extinguishment of hidden or remaining fires; placing the building, its contents, and the fire area in a safe condition and protecting them from the elements; determining the area of origin and cause of the fire; and recognizing and reserving any evidence of arson.
Overhaul
Consists of those methods and operating procedures allied to firefighting that aid in reducing fire, water and, smoke damage during and after fires.
Salvaging
Occurs when smoke and heat travel upward to the top floor of a building and then, unable to escape or travel further upward, spreads horizontally.
Mushrooming
A quick assessment of a situation to determine the nature and extent of the emergency scene, and decide what resources will be needed to resolve the emergency.
Size-up
The collection of fire vehicles at a central location for distribution as needed at a major incident scene.
Staging
The act of sorting patients by the severity of their injuries.
Triage
Situated in front or in the forward part of the body.
Anterior
A decrease in the amount of oxygen and an increase in the amount of carbon dioxide as a result of some interference with respiration.
Asphyxia
Acute reaction to heat exposure. Blood pools in the vessels as the body attempts to give off excessive heat. It can lead to collapse due to inadequate blood return to the
heart.
Heat Exhaustion
First aspect of the patient assessment, designed to determine any immediate threats to the patient’s life. It assesses airway, breathing, and circulation, and looks for significant hemorrhage.
Primary Assessment
Part of the physical assessment process where detailed historical
and physical findings are evaluated in order to determine the patient’s medical or traumatic problem.
Secondary Assessment
A life-threatening condition caused by exposure to excessive heat. Symptoms include dry skin, dizziness, headache, nausea, and muscle cramps.
Heat Stroke
Signs of life; pulse, respiration, blood pressure, and temperature.
Vital Signs
The back or dorsal surface of the body.
Posterior
A temporary loss of partial or all of the abilities of the brain to function without physical damage to the brain.
Concussion
Severe shock caused by an allergic reaction.
Anaphylactic Shock
A state in which not enough oxygen is delivered to the tissues of the body.
Cardiogenic Shock
Condition in which low blood volume, due to either massive internal or external bleeding, results in inadequate perfusion.
Hypovolemic Shock
Shock caused by severe bacterial infection.
Septic Shock
To shock a chaotically beating heart with a specialized electric current in an attempt to restore a normal rhythmic beat.
Defibrillate
Rapid heart rhythm.
Tachycardia
Small spots of generalized itching and/or burning that appears.
Urticaria
