Nassau County Firefighters conducted the demonstration by lighting a Christmas tree on fire. It took just seconds for the tree to spark and within 3 minutes, the tree was fully engulfed.

Firefighters have some important safety reminders.

Never put your tree near an exit or staircase.

Check your holiday lights. There shouldn't be any loose wiring and replace them if they are more than 3-5 years old.

Avoid using candles and extension cords. They are a big hazard this time of year.

It's also a good time to check your smoke detector to make sure it works.
