On Oct 27 at about 8:45 a.m., a gas explosion hit a ground‑floor restaurant in Incheon’s Geomdan District. The story shows how a quick, simple act can stop a bigger disaster.

Yoon Dae‑yeol, 48, was walking nearby when he saw two LPG cylinders with open valves outside the restaurant. He closed the valves and then reported the blast to police.

Police said that if the gas had kept leaking, the danger could have continued. They also said the renovation work may have been done without closing the gas valve, so an investigation is under way.

Four people in their 60s – three workers and the restaurant owner – were injured. They suffered burns and one of them had a facial fracture.

Yoon’s fast action helped stop more gas from escaping and may have saved lives. The incident teaches that ordinary people can make a big difference in emergencies.
