Smoke alarm laws were introduced after findings indicated 144 people died in house fires over a five year period in NSW. 60 percent of deaths occurred during sleeping hours.
It is compulsory for all homes to have smoke alarms installed. The legal obligation to have smoke alarms installed rests with building owners.
Smoke alarms should be positioned to detect smoke before it can reach people who may be sleeping. The sound emitted by the alarm is designed as an early warning device to wake occupants, giving them time to evacuate.
