As we approach the Fourth of July holiday weekend, the Boulder County Sheriff's Office urges all residents and visitors to be mindful of the heightened fire danger in our area. Please take extra precautions to minimize potential ignition sources, including:

• Avoid using machinery that creates sparks, such as lawnmowers, chainsaws, and welding equipment, especially in dry grassy areas, near wooded regions, and on windy days.
• Refrain from using fireworks.
• Properly extinguish campfires and dispose of cigarettes.

Additionally, please stay aware of any fire restrictions that may be enacted and keep up-to-date with current conditions, as they can change rapidly.

Let's all work together to keep Boulder County safe and prevent wildfires.
