Rain will reduce the risk of certain types of fire, but it will also increase the risk of certain types of fire.

A villager in Yongfu Village, Chedun Town called the police, and white smoke was emitting from the cabin of a truck in front of the village committee. After receiving the alarm, the firefighters rushed to the scene immediately.

When the firefighters arrived at the scene, they saw white smoke coming out of a truck parked in front of the village committee. After opening the carriage, they saw flames jumping from the surface of a metal-like substance. At this time, there was no one in the cab. When the firefighters didn't know what it was, he was not in a hurry to put out the fire, so he immediately contacted the driver. laser cutting machine fume extraction system

After the driver arrived at the scene, upon questioning, the firefighters learned that aluminum powder residue was installed in the compartment. At that time, the strong wind overturned the rain cloth, causing the rainwater to react with the substance after entering the carriage, producing flammable gas, and then causing a fire. Considering that there are more houses around, the space in the carriage is relatively closed and there is a risk of deflagration. So the firefighters asked the driver to drive the car into an open area, and then used a shovel and other tools to extinguish the fire and unload the cargo. About two hours later, the unloading was completed, the fire was extinguished, and there was no loss of personnel and vehicles. laser cutting machine fume filter

It can be seen from the above that the daily aluminum powder will cause these accidents, and the consequences of the industry will be uncontrollable.
