Fire restrictions at the Six Rivers National Forest wentinto effect Friday.

Restrictions include limiting open campfires to developed recreation sites, designated fire-safe sites and the Siskiyou and Trinity Alps wilderness areas, according to a national forest press release.

Smoking is limited to enclosed vehicles, buildings, developed recreation site and within designated fire-safe areas. Internal combustion engines are prohibited except on National Forest System roads or designated trails. Explosives, welding and operating acetylene or other torches with an open flame are also prohibited, according to the press release.

Lanterns or portable stoves using gas, jellied petroleum or pressurized liquid may be used with a valid free California campfire permit. Barbecue grills using briquettes are not allowed however.

Anyone in violation of these restrictions may be subject to a fine, six months in jail or both. A person found to have caused a wildfire may be held liable for firefighting and resource damage costs and any injuries that occur, according to the press release.
