Fire District 3 firefighters were called to Rabbit Run Road on Saturday night after a caller reported the inside of a car was coated with a suspicious yellow powder.

Emergency responders trained in dealing with hazardous materials went to the scene, and Deputy Chief Paul Busch said they discovered a simple case of mischief.

“Somebody shot off a fire extinguisher inside of a car — vandalism,” Busch said.

The call was one of few noteworthy incidents in an unusually slow summer weekend for South Whidbey’s firefighters and EMTs.

In total, from Friday to Sunday, firefighters answered seven calls. A typical summer weekend has about 20.

“That’s fine with me, though,” Busch said. “I’m not complaining.”

Two of the calls were for illegal burns or fires.

“We just asked them to put it out and advised them there’s a burn ban,” he said.

A burn ban has been in place since Aug. 8. Fires with natural debris are prohibited, but the ban does not include cooking fires in barbecues.
