"Hot Pot Restaurant Explosion" Can a single lighter send an entire table of diners to the hospital?

Worth being vigilant about. This was no accident; it was a deliberate act despite knowing the danger.

The incident took place at a hotpot restaurant in Shenyang, Liaoning. After the meal, a man threw a cigarette pack and a lighter into the boiling hotpot, triggering an explosion on the spot. The restaurant’s account was straightforward: a conflict had first broken out between customers, and staff had stepped in to dissuade them, but failed to stop it. As a result, red chili oil splattered everywhere, contaminating the tables, chairs, and walls, and the scene quickly spiraled out of control.

The most important point to make clear is that a lighter is not a toy, but a miniature pressurized container. It contains liquefied butane, and when exposed to high temperatures, the internal pressure can rise rapidly, making an explosive flare-up far from unusual. The article mentions experimental data: in an open flame, it may explode in as little as eight seconds; at 30°C, the internal pressure can reach four times atmospheric pressure, and at 50°C, it can rise to seven times.

Many people handle lighters too casually in daily life, and that is the real root of the problem. A lighter falling into hotpot and scalding multiple people, prying open a bottle cap with a lighter and causing leakage and burns, or a spray gun in a high-temperature environment igniting a nearby lighter and injuring someone’s face—none of these are new cases. It may look cheap, but its risks are anything but cheap.

No one was hurt this time, which was luck, not because the risk was small. The restaurant later spent a long time cleaning up the oil stains, and because there were no bodily injuries, the police were ultimately not called. That outcome is understandable, but it does not mean the incident was minor. It can be said that everyone at that table merely brushed past the edge of disaster.

From the perspective of public-place management, restaurants still lack a tougher layer of measures for dealing with this kind of conflict. Staff intervention is of course important, but when faced with clearly dangerous behavior, verbal warnings alone are not enough. Preserving in-store surveillance footage, calling the police immediately, and promptly evacuating nearby customers are all far more valuable than wiping down walls afterward.

Ordinary people should not count on luck either. Don’t leave lighters in the sun, don’t drop or smash them, don’t keep them in the car, don’t use them directly to light a gas stove, and after use, store them in a cool place, away from flames and children. This is not a fire safety slogan; it is the lowest-cost form of self-protection.
