As Labor Day weekend begins, fire restrictions have been eased for national-forest and BLM lands in the state of Colorado. Moisture from scattered thunderstorms is continuing to reduce wildfire risks, agency officials say.

Campfires and charcoal grills are now allowed in developed recreation sites only. Fires are still prohibited outside of developed recreation sites.

Further rainfall will be needed to eliminate fire restrictions, according to officials. Public-land agencies will continue to review the broad-scale restrictions after the Labor Day weekend.

As of Friday, the following activities are prohibited on San Juan National Forest and San Juan Field Office-BLM lands in southwestern Colorado:

• Building, maintaining, or using fire, campfires, or charcoal grills except in a developed camp or picnic area. Petroleum-fueled stoves, lanterns and heating devices can be used in the backcountry, and resident owners and lessees of land within restricted areas can have fires within a residence.

• Smoking, except in enclosed vehicles, buildings, or developed recreation sites, or while stopped within an area that is at least 3 feet in diameter and barren or cleared of flammable materials.

• Welding, or operating acetylene or other torches with an open flame.

• Operating or using any internal- or external-combustion engine without a spark-arresting device properly installed, maintained and in effective working order. Woodcutters should also carry water, a shovel and a fire extinguisher.
