Officials are urging people across the Northwest to refrain from having any campfires or setting off fireworks as hot, breezy weather poses a severe risk of wildfires.  Due to increasing fire danger, restrictions have been imposed on firewood cutting and other industrial activities on the eastern portions of the Mt. Hood National Forest.  Known as Industrial Fire Precaution Levels Units 1 and 4 to industrial operators, the restricted area covers all of Barlow and most of Hood River Ranger Districts, which have high fire danger levels.  For the average firewood cutter, the restrictions mean that they will only be allowed to operate power saws from 8:00 p.m. to 1:00 p.m. in those areas.  A one-hour fire watch is required after shut down of power saws and other equipment within the affected area.  All power saws and motor bikes are also required to have an approved spark arrestor installed while operating on the national forest.  In Washington, Public Lands Commissioner Peter Goldmark expanded a statewide fire ban to prohibit all outdoor burning, including campfires in fire pits and the use of charcoal briquettes, on state forests and parks protected by the Department of Natural Resources.  Goldmark says the greatest fire danger right now comes from carelessness.  The National Weather Service is issuing similar warnings, asking people not to burn anything outside, not to toss burning materials from vehicles and not to use fireworks.
