More than 30 students have been hospitalised following a fresh gas leak at schools in Ogun State, marking the fourth reported incident in the state since April 2026.
The incident occurred on Wednesday at Anglican Girls Grammar School in Obalende, Ijebu-Ode, including its public and private sections, and Ijebu-Igbo Girls Grammar School, among other schools.
An unusual odour was also reported in Ago-Iwoye, prompting school authorities to close their facilities and send students home.
According to a report by TheCable, the affected students were taken to general hospitals in Ijebu-Ode and Ijebu-Igbo for medical attention.
Ola Oresanya, Ogun State Commissioner for Environment, said the situation was under control and that investigations had begun to establish the source and extent of the emissions.
Speaking during an assessment visit, Oresanya said medical findings showed that the students experienced symptoms including shortness of breath, stomach disorders and drowsiness.
He explained that some students required oxygen to stabilise their conditions, while others received less intensive treatment.
Most of the students had been discharged by the time government officials completed their hospital assessment, although a few remained under medical observation.
The assessment team also visited Ijebu-Igbo Girls Grammar School to examine the situation and investigate the surrounding environment.
Oresanya said the chairman of Ijebu North Local Government Area had confirmed detecting the unusual odour, including at the council secretariat.
A team from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) also arrived at the scene to participate in the assessment and investigation.
Fourth Gas Leak Incident Since April
The latest incident follows three similar occurrences reported in Ogun State since April, raising concerns about the recurring gas emissions and their potential impact on students and school communities.
On April 1, at least 30 students of Our Lady of Apostles Secondary School in Ijebu-Ode were hospitalised after a suspected gas leak caused breathing difficulties among students and teachers. The government initially suspected fumes from nearby carbide cylinders.
On May 15, another incident affected students at Anglican Girls Grammar School in Ijebu-Ode, with several reportedly fainting and requiring medical attention.
The state government subsequently activated a multi-agency environmental and public health assessment team.
On June 3, students of Our Lady of Apostles Secondary School were hospitalised again following another suspected gas leak. It was the third reported incident in the community within two months.
In June, Oresanya attributed the recurring emissions to a possible natural geological occurrence in which underground gases escape through fractures associated with geological and tectonic fault lines.
He ruled out sabotage and gas pipeline leaks as possible causes of the earlier incidents.
However, the investigation into the recurring emissions had not been concluded as of September, when TheCable contacted the commissioner for an update.
Authorities are expected to establish the source of the latest emissions and determine what caused the symptoms reported by the affected students.
