[Home Firefighting] Why is the oil smoke road causing fire?

Most flue fires are due to no cleaning flue or cleaning is not timely or incomplete, resulting in accumulation of grease inside the flue, and the flue gas is too high to be ignited. The seemingly insignificant grease stains are very dangerous. Let's take a look at the fire tests to see how grease has become a time bomb that threatens the safety of the kitchen.

Firefighters prepared a stove and a pot. The pot is the cooking oil used for daily cooking, and then a soot pipe is placed on it to simulate the environment of the restaurant kitchen. The oil smoke pipe has also been specially treated to accumulate some grease. The oil pan produced a large amount of smoke after heating for nearly five minutes, and soon the flames were pulled out. The firefighters were dressed in professional fire-retardant suits and poured a small amount of water into the pan to simulate the explosion environment in the hotel kitchen. . At this time, the flames in the pan quickly ignite the grease stains inside the oil pan pipe, and the inside of the oil smoke pipe burns violently. The flame rapidly spreads out and spreads, and directly rushes to the top of the pipeline.

Then, switch to a household hood to continue experimenting. The experimenter prepared a hood that was used for three to four years. When the oil pan caught fire, the simmered fire quickly rose into the hood, and it quickly became red. Fortunately, the fire extinguisher was on hand and it could not be disastrous.

â–  To prevent post-kitchen fires, the following points should be noted:

1. During the purchase and installation of exhaust pipes, attention should be paid to quality clearance and installation specifications, so as to avoid the troubles caused by use and cleaning, and to avoid fixing the soot pipes to combustibles such as wooden boards.

2. The food and beverage establishments shall increase the fire education for their employees and regularly or irregularly train them to master the knowledge and methods for preventing and extinguishing the initial fire of the oil flue, and formulate corresponding fire safety management systems.

3 , restaurants, hotels and other business premises should be cleaned every two months by a professional company oil fumes Road, residents of the home range hoods should also be regularly cleaned to prevent grease blockage channels, causing fire accidents.

4 , kitchen staff must be done in the open fire, people go out of heat, cooking as much as possible to control the height of flame, to prevent the flame when cooking too high lead smoke grease pipe, and in the kitchen fire extinguishers and other fire equipment to deal with accidents.
