BONNYRIGG firefighters are urging residents to change their smoke-alarm batteries when they adjust their clocks this Sunday, April 6.
Fire and Rescue NSW is also encouraging people who are most at risk, such as seniors, to contact their local fire station if they need help to change an alarm battery.
Bonnyrigg Heights Fire Station commander Wayne Rush said the Duracell-sponsored smoke alarm and battery-replacement program will be offered to seniors for free.
"If you cannot climb a ladder and have no family, friends or neighbours to help you we'll come out and replace seniors' smoke-alarm batteries," he said.
"A fifth of all house fires involve seniors. So far in 2014, four people have died in house fires and all have been over 65.
"The most important thing those over 65 can do to reduce their risk of fire in the home is to have a working smoke alarm."
Mr Rush said a working smoke alarm gives people vital seconds to get out. Fire and Rescue NSW Commissioner Greg Mullins agreed.
"A fire can take hold in less than three minutes, filling your home with deadly smoke," Commissioner Mullins said.
"A working smoke alarm gives you vital seconds to get out before you're overcome. When daylight saving ends on April 6, change your smoke-alarm batteries, too.
