Someone cleaned this a month ago??

Here are pictures from a job just started and these pictures are new from 2 days ago. This job has been getting done on a regular basis every 3 months by a National Company who is also certified and was taking pictures. I wonder where the pictures were actually taken from?  The first job from this chain that was done had over 650 LBS of scrapped out grease the first night. Everyone thought that was bad until this location. Obviously the National Cleaning Company forgot about much of this ductwork. How to save money on cleaning grease ducts? This National Company has been finding out how, just skip most of it as you can see by these pictures!! Here are pictures from just the first nights work including a 6" chisel stuck into the grease to show how thick and the 30 gallon barrels and bus pans full of the scooped out grease that was taken out of just the first 30 feet. The KEC crew had to use a shovel for removing a lot of the grease once loosened up. You can see knee marks in the grease showing how thick it is where the KEC team crawled into the horizontal. You can also see the old towels sitting in the pools of grease. Imagine if a fire started in this duct. THere is more fuel that I have ever seen before. It would have been catastrophic. There is over 100 feet of horizontal ductwork at this location plus multi story verticals. None of this appears to have ever been touched. Access plates had to be installed in multiple locations. Only a few inches appears to have been cleaned up from the hood. I will post additonal pictures of the cleaning in progress and when complete on a later post for all to see. And yes- it is ethnic style stir fry grease. WOW!!!!
