The heating boiler exploded in a standalone boiler room near the Bauyrzhan Momyshuly secondary school in the village of Urjar, Abay region. Part of the building's roof collapsed.
The boiler operator sustained second and third-degree burns. He has been hospitalized in the surgical department of the district hospital, and his condition is reported to be stable.
According to the local administration, preliminary data indicates that the accident occurred due to a disruption in the heating system's circulation, which led to increased pressure in the boiler. The educational process for 943 students and 117 teachers has not been disrupted. A backup boiler is heating the school building. Local authorities also promise to install a new boiler in the coming days.
