Ogun State Governor, Dapo Abiodun, has ordered an investigation into the gas leak at Our Lady of Apostles Secondary School, which left several pupils hospitalised.
The incident occurred on Wednesday shortly after morning assembly, when a gaseous substance spread across the premises, causing panic.
The Eagle Online reported that no fewer than 30 pupils and one teacher were affected, with several collapsing after inhaling the substance.
They were rushed to the General Hospital Ijebu Ode for treatment.
In a statement issued on Thursday, the Commissioner for Environment, Ola Oresanya, said the governor directed security agencies to determine the cause of the incident.
He said the findings would help prevent a recurrence.
The government also ordered the immediate closure of the affected school.
Oresanya said: “Governor Abiodun has also directed the immediate opening of a Situation Room at the General Hospital, Ijebu-Ode which will offer free treatment to other students and residents of the impacted areas such as Makalewo, Ogbogbo, Molipa, Igbegba, Ikoto and Oke-Aje market.”
Residents of the affected communities were advised not to panic, as authorities said there was no confirmed security threat linked to the incident.
Oresanya said officials of the Ogun State Environmental Protection Agency had deployed gas analysers to determine the source and nature of the substance.
He added that government officials visited both the school and the hospital where victims were receiving treatment.
Most of the affected pupils and staff are in stable condition, while investigations into the cause of the leak continue.
