Mistake 1: Pour the flour next to the gas stove.

Explosion principle: Flour is a very fine dust particle. When it is dumped, it will spread into the air. When it reaches a certain concentration, even if it encounters a naked flame, it will cause an explosion, which is as powerful as a Grenade!

Correct demonstration

Never pour flour, starch, coffee powder or milk powder in a kitchen with an open flame.

Mistake 2: Put the frozen food directly into the oil pan.

Explosion principle: If unfrozen frozen food is directly put into a hot oil pan, the ice on the outer layer of the food will quickly turn into steam, making the oil pan boil immediately. Not only will the food in the pot explode and hurt people, but the boiling oil will overflow and fall on the flames of the gas stove, and it will catch fire!

Correct demonstration

Frozen food must be thawed before frying, otherwise it will easily lead to uncontrollable consequences!

Mistake 3: Pour water after the oil pan catches fire.

Principle analysis: The boiling point of water is 100C, while the boiling point of oil is about 300 C. When you add water to the oil pan, the water sinks to the bottom of the pan heavier than the oil, and then boils and evaporates quickly. At this point, the oil will become tiny oil droplets floating in the air, and mix with the air to form combustible gas, which may cause flames to rush and make the whole kitchen catch fire.

Correct demonstration

After the oil pan catches fire, turn off the fire first to avoid the fire from increasing due to continuous heating; Then slowly cover the pot from the side and extinguish the flame. During the whole process, do not move the burning pot to prevent safety accidents.

Mistake 4: Cooking soup in the kitchen is unattended

Principle analysis: Never leave the kitchen when cooking soup! Boiling soup can be easily rescued and put out the fire. At this time, if the gas has leaked, if it reaches a certain concentration, it is easy to cause fire or even explosion if it is ignited again!

Correct demonstration

When people leave the kitchen, they must put out the fire and never leave the gas stove on when no one is at home.

Mistake 5: The range hood is not cleaned for a long time.

Principle analysis: The oil dirt in the range hood seems inconspicuous, but it is actually a time bomb. If it is not cleaned for a long time, if the fire in the oil pan reaches the range hood, the consequences will be unimaginable. In addition, during the operation of the machine, the oil residue in the rotating shaft is easy to catch fire due to frequent friction, which endangers personal safety.

Correct demonstration:

Clean the range hood regularly, preferably once every three months, and the oil cup will be emptied when it is 6 minutes full.

Myth 6: gas appliance is over age.

Principle analysis: The "aging" gas stove will not only affect the normal operation, but also lead to air leakage, incomplete combustion and excessive carbon monoxide in the exhaust gas due to the wear and aging of parts.

Correct demonstration:

The normal service life of household gas stoves is generally 8 years, and they should be replaced in time after expiration to avoid hidden dangers caused by extended use.
