Whidbey Island firefighting agencies responded to three brush fires over the weekend, two of which were caused by fireworks.

The Oak Harbor Fire Department was dispatched to a brush fire on Barrington Drive around 2 a.m. on Saturday, July 1, according to Fire Chief Ray Merrill. The fire, which spanned about half an acre of grass on a hill where housing is being constructed, took around 10 minutes to put out, the chief said. There were no injuries.

The chief encouraged people who choose to use fireworks to be cautious and keep a garden hose or other water source close by.

Central Whidbey Island Fire and Rescue firefighters responded to a blaze at 1:16 a.m. July 2 on Wonn Road in Greenbank after a group of intoxicated individuals tried to dispose of spent fireworks in a bonfire, according to Fire Chief Jerry Helm. Some of the fireworks reignited and started a fire in a neighbor’s yard.

The property owner discovered the fire and managed to extinguish most of it with a garden hose by the time Central Whidbey Fire arrived. Firefighters finished putting out the 10 by 15 foot blaze, then extinguished the bonfire.

Helm said used fireworks should be disposed of in a bucket of cold water.

A grass fire sparked by a hay mower Sunday evening may have resulted in a medical event, according to South Whidbey Fire/EMS.

Firefighters responded to the small blaze at the intersection of Bayview Road and Cedar Springs Lane around 6:06 p.m. on July 2. The fire was contained to an area about 30 by 50 feet, Deputy Chief Terry Ney said, and was mostly extinguished by citizens by the time the first engine arrived. Crews provided “mop-up work.”

It was determined that the fire was caused by a hay mower striking a rock, which threw a spark into the dry grass. Ney said the person who was mowing the hay did suffer a medical event, presumably due to his exertions in putting out the blaze, and was airlifted to a hospital on the mainland.
