Why is the Gravas school reopening occurring with the gas supply shut off?
The Gravas school reopening on November 2 follows a unanimous vote by the Athens Municipal Council to prioritize extreme caution. Although the schools could have technically reopened sooner, Mayor Charis Doukas opted to delay the date to allow the educational community time to prepare for the transition from remote to in-person learning. The primary safety mandate is that the gas supply to all systems must remain closed during the initial phase of reopening.
This precautionary measure ensures that even though no active leaks were detected, the school environment remains controlled. The municipality intends to keep the gas supply disconnected until the end of November, once all additional technical actions recommended by expert reports have been fully implemented and certified. This approach aims to provide peace of mind to parents, teachers, and students after the period of remote learning that began on October 9, 2026.
What were the results of the gas leak investigations?
Six independent inspections conducted by specialized entities confirmed that no natural gas leaks were detected within the Gravas school complex. The investigation involved three distinct professional bodies: ENAON (the network operator), ICON (the company responsible for burner maintenance for the Municipality of Athens), and the Technical Chamber of Greece (TEE), which serves as a state institutional advisor. All three organizations reached the same conclusion regarding the absence of a leak.
To address concerns regarding gas odors, ENAON performed three additional high-precision checks using the advanced Picarro detection method. These specialized tests were carried out during three separate windows: October 2–3, October 9–10, and October 26–28, 2026. In all three instances, the Picarro system recorded no evidence of gas odors or chemical traces, reinforcing the findings of the initial inspections and supporting the decision to allow students back into the buildings.
How will the municipality ensure long-term safety at the site?
The Municipality of Athens has committed to a phased return to normalcy that relies on continuous technical verification. While the schools will host in-person classes starting Monday, the gas supply will only be restored after a final decision is reached following the completion of all expert-recommended studies. The municipality is currently awaiting the approval of a specific technical study before any physical work on the gas network can commence.
A representative from the gas supply company attended the Municipal Council meeting to confirm that all preparatory works are ready to begin as soon as the necessary study is approved. The municipality's strategy involves a dual track: resuming educational activities through physical presence while simultaneously finalizing the technical certifications required to safely reactivate the heating and cooking systems. This ensures that the transition from Webex-based remote learning back to the classroom is both stable and scientifically validated.

Key takeaways
- The Gravas school complex reopens on November 2, 2026, with the gas supply remaining shut off.
- Six separate inspections by ENAON, ICON, and TEE found no evidence of natural gas leaks.
- Additional Picarro method tests conducted in October confirmed no traces of gas odors.
- Full gas restoration is expected only after the end of November following technical studies.
Conclusion
The decision to reopen the Gravas school complex under restricted gas conditions reflects a balanced approach between educational continuity and public safety. By utilizing high-precision detection methods like Picarro and involving multiple institutional experts, the Athens Municipality has addressed the initial concerns regarding gas odors with scientific rigor. While the immediate return to classrooms provides much-needed stability for the educational community, the continued suspension of the gas supply serves as a vital safeguard. The final reactivation of the system will depend entirely on the successful completion of technical studies and the subsequent verification of safety protocols.
