Nigerian teachers emerge as 2018 safe school safety award winner

I think there may be a mistake here. There is no such thing as the "2018 Safe School Safety Award" that I'm aware of. Additionally, it's unlikely that Nigerian teachers would be the winners of a non-existent award.

However, I did find some information on the "Safe School Award" which is an annual award given by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to recognize schools that have made significant efforts to ensure a safe and supportive learning environment for their students.

If you're referring to this award, I couldn't find any information on Nigerian teachers winning the award in 2018. If you have any more information or context about the award, I'd be happy to help you verify the information.
