No matter what the exam, the importance of past exam questions goes without saying.
Although the number of questions that can appear in past exams is decreasing, more than 20-30% of them still appear in past exams.
Firefighting and firefighting law are specialized subjects, so the terminology used can be difficult.
First, it is necessary to understand and memorize the terminology.
For example, there are things around us, such as windowless floors, emergency exits, and indoor fire extinguishers, but we do not know much about them because we do not pay attention to them.
If you are interested in firefighting, you will easily understand.
There is definitely a flow.
For example, if you look at the Chinese characters for fire fighting, it is 消防, which means to put out and to block.
The fire department came out to put out the fire and stop it, but the combustion continued and turned into a fire.
So, we need to know what combustion is and what elements are needed for combustion to occur.
Combustion is a rapid oxidation reaction in which a combustible substance combines with oxygen to produce heat and light.
To smoke a cigarette, you need cigarettes, a lighter, and oxygen.
Cigarettes are combustible, lighters are ignition sources, and oxygen is an oxygen source.
If you remove the cigarette, you can't smoke.
That is what elimination digestion is.
If you put the lighter out with water, it will cool down and extinguish, and if you remove the oxygen, it will suffocate and extinguish.
Then we need to see what kind of medication is needed to digest it.
There are two types of fire extinguishing agents: water-based and gas-based.
In the water system, there is water and foam, and in the gas system, there is carbon dioxide, halons, cleaners, and powders.
There is a flow to putting out fires.
This is what fire science is all about.
