A house fire in Yakima Sunday afternoon was the latest in a string of fires caused by unsafe use of portable space heaters, according to the Yakima Fire Department.

Sunday's fire was reported at 2:33 p.m. in a home in the 1700 block of South First Street, according to a fire department news release. Firefighters arrived to find black smoke billowing from the home but were able to quickly extinguish the fire, according to the release. No one was home at the time of the blaze, and damages are estimated at $15,000.

Subsequent investigation found the fire was started by a faulty electrical outlet and the use of portable space heaters, according to the release.

This was the fourth fire in a week reportedly caused by use of space heaters:

The fire department said if you have to use portable heaters, give them three feet of clearance, check the cords for damage or wear, and never use extension cords or power strips to power a heater.
