One conclusion is that it was particularly cold that day and everyone in the household must have stayed near the space heater. One of the children could have left a blanket near it before they have all gone to sleep.

Some advice on how to protect oneself from fire at home:

1. Never run a power extension cord under a rug

2. Make sure to stay in the kitchen when cooking

3. Unplug all appliances when not in use

4. Check for faulty wirings

5. Keep a fire extinguisher and install smoke alarms

6. If caught in a fire, stop, drop and roll
