With increasing fire danger, the Oregon Department of Forestry will move lands in its The Dalles Unit under its MH-4 protection area to Industrial Fire Precaution Level 3 as of Thursday.  This effects all industrial operations west of Highway 35.  There will be a 2-hour fire watch required after operations are complete.  Under Industrial Fire Precaution Level 3, the use of fire or power-driven machinery in any operation area is unlawful unless such use falls within the time period of 8 p.m. and 1 p.m.  That includes power saws at loading sites, loading or hauling of any product or material; blasting; the welding, cutting, or grinding of metal; and any other spark emitting operation not specifically mentioned.  Other equipment can be used under if mechanized equipment is immediately available to quickly reach and effectively attack a fire start and construct fire lines.  Contact the Oregon Department of Forestry for specific information.
