Yesterday I pulled up to my girlfriends house got out of my truck and started toward the door. I glanced over at the rival companies trailer which was parked by the next door neighbors house and I saw fire. I instinctively ran up to see what was burning. Right about that time one of the crew members from the rival company noticed it and ran up as well . I told him to go to another neighbors house who was mowing the lawn and ask for a fire extinguisher and to call 911. He did while I ran to my girlfriends house to ask the same question. I ran over with a 30 year old extinguisher and squeezed the trigger. EMPTY. So I ran back to my girlfriends house and extended the hose which had to have been 150 feet long as close as I could to the mower that was on fire and sprayed it which barely made it. But it did and it made a decent knockdown on the fire which thankfully had not spread to the gas tank. It turns out it was just a debris bag on a Exmark walk behind burning that started from a Wright Standers exhaust making contact with the bag Lesson Learned YOU MUST HAVE A FIRE EXTINGUISHER OR YOU COULD LOOSE YOUR EQUIPMENT! Although the gas tank wasn't at risk in this particular situation it could have been rendering the water useless. Coincidentally I also serve as a firefighter for the local township that the fire occured in so I'll have something to talk about next shift at the firehouse.
