Greater Manchester Fire and Rescue Service (GMFRS) and Manchester City Council say they are working with the owners of a block of flats which caught fire over the weekend.
The fire, which started at around 4pm on Saturday, spread over multiple floors in the 12-storey building on Joiner Street in the city's Northern Quarter.
Images posted on social media showed flames engulfing a number of floors and smoke billowing out, while crowds of people watched on from below.
More than 50 firefighters tackled the blaze which started in the open plan kitchen area of a ninth floor apartment.
Whilst some residents claimed that alarms couldn't be heard as flames spread to other floors, GMFRS said the building's alarm systems worked as they were designed to do - with a smoke detector warning the occupant of the fire, who then evacuated. When the building-wide communal fire detection subsequently activated, it initiated a call to the fire service and triggered the safety features of the building installed for firefighting.
Since the incident, crews and specialist officers say they have thoroughly checked the 20-storey building. Inspections have established that the building's integrity and safety is suitable for the majority of people living in the apartments to return to their homes. Landlords have arranged alternative accommodation for the residents of the seven apartments affected on the ninth floor.
As an additional precaution and reassurance measure, GMFRS specialist fire safety officers say they are working with the managers of the building to instigate a phased evacuation process for any future incidents as an interim measure.
Officers inspecting the building have concluded that the cladding systems did not contribute to the fire, and the fire spread is down to the external timber balconies adjoined to each apartment. Inspections have also detailed that the construction of the building does meet the national building regulation requirements.
Deputy Mayor of Greater Manchester – Crime, Policing, Criminal Justice and Fire, Beverley Hughes said: “
GMFRS say they have been in discussions with the National Fire Chiefs Council and are seeking national guidance regarding wooden balconies on apartment blocks. Following this, they will consider if further fire protection is needed.
