Which gas catches fire easily?
The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances. Examples of inflammable substances are petrol, alcohol, Liquified Petroleum Gas (LPG) etc.
What are the 4 behaviors of fire?
Fire behavior includes such things as how fast a fire burns (rate of spread), how hot it burns (fire intensity), the presence of fire whirls, and ember production and spotting.
What are the five stages of fire?
The five stages of fire growth are incipient, free burning, flashover, post flashover and decay. The incipient phase is characterized by localized flame to the fuel source and low heat release.
What is a Level 3 fire?
A Level 3 means those within the evacuation area should leave immediately. The Elbow Creek Fire is now estimated to have burned 9,000 acres.
What are the 10 phases of fire operation?
A welltrained fire fighter knows that there are many phases in a structural fire fighting operation, including rescue, exposure protection, attack, ventilation, confinement, extinguishment, salvage and overhaul.
What is the first stage of fire?
Stages of fire Ignition: Fuel, oxygen and heat join together in a sustained chemical reaction. At this stage, a fire extinguisher can control the fire. Growth: With the initial flame as a heat source, additional fuel ignites. Convection and radiation ignite more surfaces.
What is the biggest cause of death in a fire?
The majority of fire-related deaths are caused by smoke inhalation of the toxic gases produced by fires. Actual flames and burns only account for about 30 percent of fire-related deaths and injuries. The majority of fires that kill or injure children are residential fires.
How does something catch fire?
Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.
