With the arrival of summer temperatures and the Fourth of July holiday, the Washington State Department of Natural Resources is urging people to be cautious of rising fire danger.

DNR records show wildfires occur more on weekend and holiday afternoons, when more people visit DNR-protected lands. Unattended campfires, faulty vehicle or motorcycle mufflers, careless disposal of cigarettes, and dragging tow chains behind vehicles also increase the risk of wildfire during the long holiday weekend.

The 2016 wildfire season burned 305,153 acres and cost Washington taxpayers more than $40 million. Those who start wildfires can be held responsible for suppression costs.

To avoid accidental wildfires, practice these prevention tips:

Camping and recreating

· Only build campfires where authorized and when not under a burn ban; put them completely out before leaving camp, even for a few minutes; use plenty of water and stir until the coals are cold to the touch.

· Dispose of lit smoking materials appropriately.

· Fireworks, incendiary ammunition and exploding targets start fires and are illegal to use or discharge on public lands, including all state forests.

Vehicles and Towing

· Be sure chains and other metal parts aren’t dragging from your vehicle or trailer. They can throw sparks and start fires.

· Make sure all off-road vehicles have a properly functioning and approved spark arrester.

· Be careful driving through or parking on dry grass or brush. Hot exhaust pipes can start the grass on fire. You may not even notice the fire until it’s too late.

· Check tire pressure and condition. Driving on an exposed wheel rim can cause sparks.

· Have brakes serviced regularly to prevent brake pads wearing too thin; metal on metal can spark or drop pieces of hot brake pad.

Outdoor burning

In Washington, outdoor burning is a leading cause of wildfire ignition. Be aware of shifting winds, especially if burning outdoors.
