California Launches “One Less Spark” Wildfire Prevention Campaign

July 15, 2026 – CAL FIRE launched the “One Less Spark” awareness campaign which informs Californians on how safe vehicle and equipment use can help prevent human-caused wildfires. CAL FIRE is running paid advertising across digital, radio, and billboards in State Responsibility Area throughout California, paired with a statewide network of partners and organizations that will carry the message into their own communities. CAL FIRE has built a public-facing toolkit of ready-to-use assets, including social media content and educational materials that partners can adapt and share.

Steps you can take to prevent One Less Spark:

• Mow before 10 a.m.: Mowing the lawn on a hot, dry, or windy afternoon can be risky. If the mower’s blade hits a rock, it can create a spark. So, mow before 10 a.m. and avoid mowing on very hot or windy days.
• Secure tow chains: Dragging tow chains can send sparks into dry brush. Secure tow chains so they do not drag on the road while you are driving.
• Get a permit: Before burning debris on your property, check your local laws and get a permit if necessary. Follow safety precautions and always have a hose or other water source nearby.
• Park safely: Something as simple as parking your car on dry grass can ignite a fire. Your vehicle’s exhaust system can get hot enough to spark dry vegetation. Do not park your vehicle on dry grass — whether it’s by the side of the road or on your property — where the engine heat could start a fire.
• Use equipment safely: Welding, grinding, or using power tools near dry vegetation can start a fire if done at the wrong time or without the right precautions.
