Falling fans are very infrequent. Few fan falls have been recorded in the last ten years. Mainly, fans would not fall by themselves. They only collapse due to rotten wood, damaged ceilings or improper installation.
How do I know if my ceiling fan is going to fall?
Wobbling will not cause the fan to fall, and there have been no such reports. Wobbling can, however, cause light fixture covers or shades to loosen and potentially fall. These items should be securely attached, with all screws tightly set in place.
How many deaths a year are caused by ceiling fans?
About 19,700 people are injured from ceiling fans falling due to improper mounting every year. Between 1995 and 2003 there were 4.5 deaths a year reported due to electrocutions from improperly wired ceiling fans.
