Strategy for Protecting the Home from Fire

In theory, the fire occurred if there are no elements, ie fuel, heat and oxygen. By experts, the three elements forming the fire was named the fire triangle. To cause a fire, three elements must be present and connected. Therefore, if you want to put out the fire, then at least one of the three elements that must be removed or separated. Or in other words, the relationship between the three elements that must be decided.
Not All Use Water
The most commonly used to extinguish fire is water. Flushed water will lower the temperature of the hot fire. In addition, some of the water used for steam flushed into the water will evaporate. Well, water vapor is what will separate the fire of oxygen. Because two of the triangle of fire-heat-and oxygen-no, the fire had become extinguished.
But, not all fires can be extinguished with water. Water can extinguish fire fuel from wood, cloth, plastic, or paper. The fire originated from sparks of electricity can not be extinguished with water. Water can actually deliver the electricity thus become a big fire. It could be that the fire instead of electricity shock. If there is a fire caused by electric current, the first thing to do is to cut power, only then could be washed down with water.
Then, what about kerosene or gasoline? Fuel the fire that came from the two elements that must be extinguished with chemicals. Its form can be either foam or carbon dioxide. Using water will not extinguish the fire due to a smaller specific gravity oil from water. When subjected to water, oil will remain above water, and keep in touch with oxygen. Consequently, the flame will remain lit even be more spread out because the water will drain the oil in all directions.
The mothers we’d never taught to cover the fire with wet gunny sacks. This can be done if the fire is still small in scale. Moistened burlap sacks will close the entry point of oxygen so the fire goes out.
Lightweight Fire extinguisher
As first aid to fire, fire department recommends every home have a fire extinguisher lighter (APAR). There are two types of fire extinguisher that is now circulating in the market, namely fire extinguisher and a new tubular-shaped capsule.
Extinguisher (often called fire EXTINGUISHER) is the most famous fire extinguisher. The most commonly used is a tube that contains carbon dioxide (CO2). Once the CO2 is sprayed, will fill the air. Because of its density is greater than oxygen, it will be under and over the relationship of fire with oxygen. The fire was extinguished.
Besides containing CO2, there’s fire extinguisher containing halon gas or dry chemical (containing sodium bicarbonate or potassium bicarbonate). Dry chemical to extinguish fires more quickly assessed by direct fire with powder coating. However, he will leave residues that may damage electronic items.
Capsule Shape
Now there are new technologies for the APAR. The instrument was given the name Bonpet Inno-shaped glass capsules containing liquid chemicals, which can extinguish the fire on medium wood, paper, textile, plastic, linen, rubber, and celluloid.
The workings of this capsule is to lower the fire department shut the inlet temperature and oxygen. When there is a fire, the capsule can be thrown into the fire point or mixed into the water, and will work on the range of approximately 7-10 meters. As temperatures around 85-90 degrees Celsius, the capsule will be broken automatically.
