Recently, a excavator caught fire while working at the dam construction site in Wuzhu Village, Qiupu River, Chizhou, Anhui. After receiving the alarm, firefighting and rescue personnel quickly rushed to the scene. The firefighters who arrived discovered that the excavator was burning fiercely, and thick smoke was billowing at the scene. Based on the on-site situation, the firefighters laid water gun positions to deal with the fire, and soon the open fire was successfully extinguished. To prevent it from reigniting, firefighters used water guns to continuously cool the excavator. After the fire was extinguished, the excavator had already burned into an empty shell. Fortunately, the accident did not cause any casualties.

After entering summer, the temperature gradually increases. Before working on excavators, it is necessary to conduct safety performance checks to avoid spontaneous combustion. The following knowledge about self ignition prevention should be familiar with:

1. Keep the vehicle body clean and free of oil stains, and eliminate dirt.

2- Regular inspection of various oil pipes is required.

3- Regular inspection of electrical circuits is required, and aging circuits should be replaced in a timely manner.

4- Operators should develop good personal habits.

5- Fire extinguishers should be readily available in the vehicle.
