Athens Grava school complex evacuated over gas odor as inspections find no leak

Morning alert and campus evacuation

Authorities ordered the preventive evacuation of the Grava school complex in Athens on Friday, 2 October 2026, after staff and students reported an intense odor resembling butane gas. The facility serves as one of the largest educational hubs in the capital, accommodating approximately 3,000 students and more than 400 teachers across primary, secondary, and upper secondary institutions. At 09:05, the Director of Secondary Education placed an urgent phone call to Athens Deputy Mayor of Technical Services Paris Charlaftis and Deputy Mayor of Education Thomas Georgiadis to report the condition. School administrators immediately began sending students out of the classrooms as emergency responders were mobilized. By approximately 11:30, classroom activities, including a scheduled fifteen-member student council session, were halted as doors opened and occupants exited the grounds.

Technical inspections and municipal response

The Hellenic Fire Service deployed two fire engines and six firefighters to carry out an on-site assessment of the infrastructure. Municipal officials alerted the Greek Gas Distribution Company, Enaon, which dispatched an inspection team to conduct atmospheric and technical measurements across the campus. The initial inspection by technical teams detected no gas leak across the inspected network. Despite the negative initial result, the Municipality of Athens deployed a second municipal crew to execute an independent inspection and draft a comprehensive safety report. Municipal police and Hellenic Police officers assisted in securing the area while technical personnel continued evaluating the school buildings.

Safety complaints and evacuation procedures

Teachers and parent representatives stated that the gas smell had been reported multiple times over the preceding sixteen days. Andreas Kargopoulos, president of the Secondary Education Teachers Federation (OLME), arrived at the campus during the morning response. Kargopoulos explained that formal complaints had been filed as early as 16 September, but schools had received no written guarantees verifying safety. He identified the 21st Gymnasium, the adjacent 40th General Lyceum, and nearby primary schools as the primary areas where the odor was strongest. Kargopoulos also noted logistical difficulties during the evacuation, pointing out that two primary schools lacked a formal evacuation protocol, obliging teachers to phone parents directly to pick up their children.

The federation president stressed that school principals could not rely on unverified verbal statements to ensure student safety.

What the principals asked for, and they are right, is that there must be a written assurance that there is no problem. When you have 250 students in here and you are responsible, you cannot take the responsibility with a verbal order or interpretation.

Parent federation response and next steps

Representatives from the Supreme Confederation of Parents of Students of Greece (ASGME) visited the campus following calls from concerned families. ASGME president Vangelio Platania noted that parents had experienced severe anxiety due to the recurring smell and the unresolved risk of a pipeline leak. Platania stated that written complaints demanding inspections had been submitted by parents and staff since 16 September. Municipal authorities declared that city officials, fire crews, and police forces will remain stationed at Grava until technical teams eliminate any possibility of hazard. School administrators are awaiting the final written verdict from the Fire Service and inspection crews before deciding on the resumption of normal operations.
