Hopefully all have enjoyed the extra hour sleep they would have gained on Sunday morning because of the changing time.

This adjustment of time means that many of the earlier risers can now also appreciate the break of dawn rather than waking in the dark each morning, but darkness will fall earlier in the evening.

Daylight Saving has attracted its fair share of supporters and critics alike. However, one initiative of the concept has become invaluable in recent years.

That is the campaign to encourage people to check their smoke alarm batteries at the same time as they wind back their clock.

It is the perfect reminder for a very important household safety issue.

Smoke alarms are life-saving devices, capable of detecting smoke well before it would be detected by a sleeping occupant.

This is why the NSW Government took steps to make smoke alarms compulsory where people sleep - in houses, other accommodation buildings, and moveable dwellings such as caravans.

But these potentially life saving devices are only effective if they are working properly, which includes ensuring that the battery is in full working order.

If you haven't already changed the batteries on smoke alarms in your home then now is the perfect time to tend to the job.

Such a move could mean the difference between life and death in the case of a house fire.

Fire and Rescue NSW can also assist the elderly and people with disabilities to change their smoke alarm batteries as part of the SABRE program.

Eligible residents can contact their local Fire and Rescue NSW Fire Station or call 1800 151 614.
