Sparks start fires all the time. That is why there is no grinding of any kind in the pit. One of the most spectacular spark generated fires that I know started in the roundhouse of the Durango Silverton Railroad a few years back. A worker was doing some bench grinding and some of the sparks ended up in the insulation between the inside and outside walls behind the bench. It smoldered for hours before setting the building on fire during the night. No one was hurt but a lot of antique equipment was damaged.
