HOUSING bosses ordered fire safety work on two high-rise blocks of flats in Glasgow just days after a blaze in which a man died.

Glasgow Housing Association, which manages the flats in Toryglen, say they carried out the work after discussions with Strathclyde Fire and Rescue.

The Evening Times understands concrete was laid around vents on an old internal hot air heating system in two buildings in Prospecthill Circus. The work was completed last Monday, six days after the fatal fire.

GHA stress the move is a "belt and braces" measure, and that the tower's disused heating system has been there since it was built, without incident.

A GHA spokeswoman said: "The investigation into the fire is not yet complete but there is absolutely no indication that it was caused by any technical or construction issues with the building.

"The safety of our tenants is of the utmost importance and we have been working with Strathclyde Fire and Rescue since the fire to offer extra home safetychecksto all residents and put in place some additional safety measures at the flats.

"This has included concreting works to the floors and ceilings of the corner flats, around the ducting for the old hot air heating system.

"The concreting work was a precautionary measure to ensure our tenants are belt and braces' safe in their homes."

Further flats in the city have also been checked, she added.

The fire, which took hold in the second-top 19th floor flat, then spread to the floor above.

The man who died was named as John Paterson, 50. Ten other people, including three-week-old twins, were evacuated.

Immediately after the fire, residents told the Evening Times they wanted out of the flats.

One tenant, who lives several floors below the 19th, said yesterday that she did not feel safe in her home. She said she had felt heat coming through open heating vents in her hall and bedroom during the fire, but did not see any smoke.

The 27-year-old mum said: "They came out afterwards and put concrete into the holes. With two kids here, it's worrying."

One expert said it was possible open heating ducts could provide a route for fire to spread.

Dr Chris Pearce, a reader in civil engineering at Glasgow University said: "One of the things you look for in a building is compartmentalisation, where you contain a fire for a certain amount of time.

"If a building has some kind of ducting running through it, that's going to provide a route for fire."

GHA say the flats met minimum fire containment times prior to the recent work.
