How Do Fire Blankets Work to Extinguish Fires

1. Suffocate the fire source: The fire blanket is a passive fire-extinguishing equipment. Its main function is to suffocate the flame by blocking the connection between the fire source and the air. When a fire blanket is dropped onto a fire area, it will quickly unfold and cover the fire source, forming a sealed isolation layer. This isolation layer effectively cuts off the contact between the flame and the surrounding air, reducing the oxygen supply to the fire source, causing the flame to gradually suffocate and extinguish. This method of extinguishing fires is especially suitable for small-scale fires, such as oil pan fires or paper fires.

2. Heat insulation function: In addition to suffocating fire sources, fire blankets also play an important role in heat insulation. During a fire, the flame releases a large amount of heat. This high-temperature heat will quickly spread and ignite surrounding combustible materials. The coverage of the fire blanket can effectively prevent the flame from transmitting heat to surrounding objects and provide a certain degree of heat insulation. This is critical to preventing the spread of fire, especially as fire blankets can temporarily control the fire until firefighting teams arrive.

3. Prevent the spread of liquid fires: For liquid fires, fire blankets can also play an effective fire-extinguishing role. Liquid fires usually start at the point of origin and spread further by burning on the surface of the liquid. In this case, quickly covering the fire source with a fire blanket can effectively cut off the contact between the flame and the liquid, thereby quickly extinguishing the fire. The covering effect of the fire blanket can not only control the spread of liquid fire sources, but also reduce the threat of fire to the surrounding environment and personnel.

4. Prevent sparks from flying: During the fire extinguishing process, fire sources such as sparks and sparks may fly when the flame is extinguished. These sparks may cause new fires and aggravate the spread of the fire. The covering effect of the fire blanket can effectively prevent the splash of sparks, completely extinguish the flames, and ensure the safety of the surrounding environment. This function of preventing sparks from splashing is especially suitable for fire scenes such as wild areas, forests and oil fields, and can minimize the damage of fires to the environment and personnel.

5. Safety: The fire blanket is a very safe and easy-to-use fire extinguishing equipment. It does not require complex operating skills and can be used easily by anyone. Compared with other fire extinguishing equipment, fire blankets do not produce any violent chemical reactions or release harmful gases, so the safety risk to users during use is very low. This makes fire blankets a necessary fire-fighting equipment in homes, schools, offices and other public places, which can effectively improve fire-fighting emergency capabilities and ensure the safety of people's lives and property.
