Summary: A haul truck was taking waste to the dump when the driver of the following truck saw fluid coming from truck. He advised the driver via two-way radio and then saw what appeared to be a small flame. The flame grew in size to about 40 cm. After more discussions with the truck driver, the onboard fire suppression system was activated to extinguish the flame.

- activate the fire suppression system
- initiate the mine’s emergency response.
