Quick Answer
To monitor a ground burn's safety, keep a safe distance, maintain a clear escape route, and be prepared to extinguish the fire with a fire extinguisher or by digging a firebreak.
Assessing Fire Behavior
When monitoring a ground burn, it’s essential to understand the fire’s behavior and potential spread. Look for signs of wind direction, temperature changes, and fuel availability. Be aware of the fire’s rate of spread, typically measured in inches per minute. A slow-moving fire is more manageable than a fast-moving one. Keep in mind that a fire can spread rapidly in dry conditions, with rates exceeding 10 inches per minute.
Firebreak Creation and Maintenance
Creating a firebreak can help contain a ground burn and prevent its spread. A firebreak is a barrier of bare earth, gravel, or other non-combustible materials that can stop the fire’s progress. To create a firebreak, dig a trench at least 10 feet wide and 1-2 feet deep, removing any combustible materials. Maintain the firebreak by regularly inspecting and repairing it as needed.
Fire Extinguishing Techniques
In the event of a ground burn getting out of control, know the proper techniques for extinguishing it. For small fires, use a fire extinguisher rated for Class B or Class C fires. For larger fires, create a firebreak and use water to starve the fire of oxygen. Be cautious when approaching the fire, as hot embers can persist for hours after the main fire has been extinguished. Keep a shovel or other tool handy to scoop up embers and prevent re-ignition.
