In Koszalin, Poland, an escape room became the site of a devastating incident where five teenagers lost their lives due to carbon monoxide poisoning. The group, comprised of young individuals aged between 15 and 18, was participating in a recreational escape room activity which involves solving puzzles to 'escape' from a locked room within a certain timeframe. However, unbeknownst to them, a malfunctioning gas heater inside the venue was emitting deadly carbon monoxide, a colorless and odorless gas that can be lethal in high concentrations.

Emergency services were called after the group failed to exit the room at the end of the activity. When responders arrived, they quickly realized that the situation was dire. The conditions inside the escape room were most likely exacerbated by poor ventilation, leading to a rapid accumulation of carbon monoxide. Despite the immediate rescue efforts, the outcomes were tragic as the young participants succumbed to the effects of the gas before help arrived.

This incident raised significant concerns regarding the safety regulations governing escape rooms and similar recreational facilities in Poland. In the wake of the tragedy, inspections of such venues were called for to ensure compliance with safety standards and prevent future occurrences. The event sparked discussions about the responsibilities of business owners to provide a safe environment and the measures that should be in place to protect patrons.
