Quick Answer
Ground burns occur when a fire, usually a wildfire, burns hot enough to char the ground. This can create a hazardous environment for those responding to the fire, including firefighters and emergency responders.
Causes of Ground Burns
Ground burns are often caused by extreme heat from a wildfire, which can melt the soil into a glass-like substance called “glassy soil.” This can occur when a fire reaches temperatures of 1000°C (1832°F) or higher. The resulting ground surface can be as hot as 300°C (572°F) for several hours after the fire has passed.
Hazards Associated with Ground Burns
Firefighters and emergency responders are at risk of injury from ground burns due to the extreme heat and reduced traction on the glassy soil. This can lead to falls, slips, and sprains, which can be exacerbated by the weight of heavy firefighting gear. To mitigate this risk, responders should use extreme caution when approaching areas with ground burns and follow established safety protocols, such as using ropes or anchors to secure themselves.
Safety Precautions for Ground Burns
When encountering ground burns, responders should wear personal protective equipment (PPE) that includes heat-resistant gloves, boots, and face shields. They should also use a fire-resistant mat or other safety equipment to protect themselves from the heat. Additionally, responders should be aware of the temperature of the ground surface and use a thermal imaging camera to detect hot spots.
