Hundreds of properties across Sheffield are having lifesaving sprinkler systems installed thanks to a partnership between the fire service and council.
More than 540 flats in Gleadless Valley, Westfield, Stannington and Netherthorpe are being targeted to dramatically improve fire safety measures.
One hundred homes have already benefited from the project that started in November and was devised by South Yorkshire Fire and Rescue and Sheffield Council.
The rest of the sprinkler systems are due to be fitted by September.
Technical fire safety manager Amy Jenkinson, urged any residents involved in the scheme to arrange for the work to be carried out immediately.
She said: “The combination of working smoke alarms and a home sprinkler system reduces the risk of death from fire by more than 80 per cent.
“Automatic fire sprinklers are most effective during the initial stage of a fire occurring, as a properly installed sprinkler will detect heat, initiate an alarm, and activate just moments after the flames appear.
“I would encourage everyone who receives a letter about the work to call the number provided as soon as possible so access can be arranged to carry out this essential work.
“The quicker the project is completed, the faster everybody’s safety is improved.”
A Sheffield Council spokesman said: “We are working hard to make sure that our tenants and leaseholders are fire safe and fully aware of the dangers a fire can bring, especially in flats and maisonettes.
“The fire suppression and sprinkler projects are a part of a large four-year investment programme for council housing in the city to ensure tenants are safe in their homes.”
The project follows the successful retrofitting of an automated sprinkler system at the Callow Mount block of flats in Gleadless Valley, which was internationally recognised for the improved safety it offers residents.
