Owners of older villas in Dubai have been urged to install a new type of smoke detector. Dubai Civil Defence has launched a campaign to urge people living in old villas to install the new smoke detectors, which can help to save lives from smoke inhalation if a fire starts while residents are sleeping. Major General Rashid Thani Al Matroushi, Directorate General of Civil Defence, said smoke is the main reason for death during fires. He added: “Smoke is the silent killer in fires as 70 per cent of people die due to suffocation while they are asleep. People always escape from the flames but they don’t know smoke is more danger.” The recommended system has detectors in all rooms and is linked with a Bluetooth system. So if one detector starts it alerts the others.
