Identification of the cause of the stove fire

Gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas for direct fire heating. There are always incidents involving gas stoves every year, and some even pose fire and explosion risks. Due to long-term use of gas, gas is prone to phenomena and failures such as failure to ignite, yellow fire, red fire, off-flame, off-fire, and backfire, especially failures such as off-flame, off-fire, and backfire. When certain conditions are reached, fire and explosion accidents will occur.
In the case of stove fire cause identification cases, Zhongke Testing can provide stove fire cause identification services.

1. Gas leakage: Gas leakage occurs due to problems such as broken pipes, loose joints, aging faucets, etc. Once it encounters an open flame, it will cause a fire.
2. Grease blockage: During use, grease will accumulate on the burner head, which will lead to insufficient gas and easily cause fire.
3. Improper use: such as cleaning the stove with flammable materials, improper placement of the stove, accidentally touching the stove fire, etc.
4. Aging of gas stoves: Due to long-term use, the pipes and valves in gas stoves age, causing leaks and fires.

Zheng bought a stove and a pressure reducing valve in the market and installed them in his kitchen. One day while cooking, the fire on the stove suddenly became uncontrollable and Zheng was seriously injured. His family rushed him to the hospital in time, but he was diagnosed with extensive burns. Therefore, Zheng sued the court and asked the stove company to compensate for economic and mental losses.
was entrusted by the court to conduct an identification and analysis of the cause of the stove fire involved in the case.
identification analysis results:
identification analysis experts investigated the stove and found that there were no quality problems. So the goal shifted to other possibilities, and finally the pressure reducing valve was locked. It turned out that there was a quality problem with the pressure reducing valve clamp and it was not fully locked, causing gas leakage and eventually causing the stove to burst into flames.
