I have a fire chief friend. He’s made me paranoid about fire hazards. I unplug all small appliances after each use.
As a property manager, one of the worst blazing fires was caused by a cheapo (glade or likewise) candle. The sprinklers & the fire department put it out quickly.
But, the worst damage to an apartment was caused by a hair dryer that was left plugged in prior to the tenant leaving for a weekend trip. Prior to actually burning, the dryer which had been propped on the vanity, slipped into the sink, and turned on. The dryer over heated. The plastic began melting. The melted plastic then blew all over the entire apartment. Fire damage was minimal since it was contained in the sink. However, the plastic damage ruined ll fixtures, appliances, cabinets, carpet -etc. It looked like a thousand spiders wove black silk webs down from the ceilings and onto every surface.
