(Baonghean.vn) - Due to the increasing demand for business premises, houses along the main roads have been renovated and converted to rental businesses. Many families rent out the lower stalls and renovate and solidify the upper floors for living, which poses many dangers if a fire or explosion occurs. The program "Citizens ask, authorities answer" recently had a discussion with Lieutenant Colonel Nguyen Dinh Hanh - Deputy Head of the Fire Prevention and Rescue Police Department of Nghe An Province Police on this issue.
