Social networking company Facebook has activated its safety check feature following the collapse of a building in Itafaaji area of Lagos Island, southwest Nigeria on Wednesday.
The safety check feature is activated by the company during natural or man-made disasters and terror-related incidents to quickly determine whether people in the affected geographical area are safe.
Concise News observed on Thursday that Lagos residents and other residents in other state have since started using the feature on Facebook.
It was gathered that when an incident such as an earthquake, hurricane, mass shooting or building collapse occurs where people might be in danger, a global crisis reporting agency alerts Facebook.
At least 10 persons, including four schoolchildren, were feared dead on Wednesday when a three-storey building, which housed a school, Ohen Nursery and Primary School, and residential apartments, crumbled around 10am.
Rescue efforts have been underway since the incident occurred, with about 50 persons rescued by officers of the Lagos State Emergency Management Agency and other emergency responders, including the National Emergency Management Agency, the Nigeria Police Force and the Nigeria Red Cross Society.
However, Lasema has said there is no casualty left under the debris of the collapsed building in the area.
General Manager of Lasema, Adesina Tiamiyu, who spoke with newsmen at the site of the incident on Thursday morning, said those trapped in the collapsed building had been rescued.
“We stopped work at 3: 00 a.m after recovering the lifeless body of a male and we are sure there is no casualty left under the debris,” he said.
He, however, said Lasema could not confirm the total figure of casualty, saying the ministry of health would release the accurate figure later in the day.
Tiamiyu also denied claims that over 100 pupils were trapped in the collapsed building.
He said: “I have seen the picture of the building before it collapsed and I can confirm to you that the floor that housed the school cannot accommodate up to 100 pupils.”
He added that “only the school administrator can tell us the number of pupils in the school, but the proprietor is also at the hospital receiving treatment and we can’t confirm that now.”
