Chapter 1: The Technology Of Fire Flashcards
Every human used this to warm themselves, cook food and frighten away predators.
Fire
Roman Goddess of the earth.
Vesta
Bestowed with Godlike powers when he stole the God’s fire to give it to humanity.
Prometheus
They made use of fire so that they can remain active after the sun set protect themselves from predators, warm themselves, cook and make better tools.
Hunter Gatherers
It is one of the oldest methods of starting fires that consists of rubbing two piece of woods together.
Two sticks
It is a more efficient method than two sticks, rapidly spinning a stick of wood against another piece of wood together.
Hand drill
What type of lens used in magnifying glass?
Concave Lens
This method generates a spark to set kindling a fire.
Percussion method
It refers to the study of the organization and function of fire prevention and suppression techniques.
Fire Technology
It is a result of rapid chemical reaction between a fuel, heat, and oxygen.
Fire
Burning is also called?
Combustion
Is a chemical reaction involving combustible materials and an oxidizing agent producing hest or energy.
Combustion
It is the energy to support the fire.
Heat
The material or substance being burned in the combustion process.
Fuel
It is the common oxidizing agent.
Oxygen
A colorless, odorless gas and one of the composition of air which is approximately 21% by volume.
Oxygen
The three elements of fire is commonly known as?
Fire Triangle
When the temperature of a substance is very high, it releases highly combustible vapors known as?
Free radicals
It is a four sided representation of causes of fire.
Fire tetrahedron theory
It is the most important part of the fire Triangle.
Fuel
Fuel comes from three forms known as?
Solid, Liquid and Gas
Ordinary combustible materials that are usually made of organic substances.
Class A fuels
Materials which are in the form of flammable liquids.
Class B fuels
Materials which are normally fire-resistant.
Class C fuels
Material that are combustible metallic substances.
Class D fuels
Materials that are combustible gases.
Class E fuels
This are the second type of solid fuels.
Fibers and Textiles
These are included as ordinary fuels under class A.
Plastics
It is a chemical used in bombs.
Cellulose Nitrate
It refers to the chemical process whereby fire consumes the most solid part of the fuel.
Pyrolysis
It is the thermal decomposition of a solid fuel through the action of heat.
Pyrolysis
Petroleum is also called as?
Crude oil
It is used to provide energy for most motor vehicles and pistol engine airplanes.
Gasoline
Provides powers for most trains, ships and large trucks.
Diesel oil
It provides energy for jet planes.
Kerosene
These are light oils, which are used chiefly to heat homes and small buildings.
Distillate oils
It refers to any liquid having a flashpoint below 37.8°C.
Flammable liquids
It refers to any liquids having a flashpoint at or above 37.8°C.
Combustible liquids
A gas which at all normal atmospheric temperature inside its container, exist solely in the gaseous state under pressure.
Compressed gas
A gas which at all normal atmospheric temperature inside its container, exist in the liquid state and partly in the gaseous state.
Liquefied gas
A liquefied gas which exists in its container qt temperature far below normal atmospheric temperature.
Cryogenic gas
These are customary used for burning with air to produce heat, which in turn is utilized as power, light and process.
Fuel gases
These are used for industrial processes as those used in welding and cutting.
Industrial gases
These are used for treatment and respiratory therapy.
Medical gases
