Everyone of the people I was with and myself regularly use the gas furnace for several reasons.
At work, the gas furnace is used to heat up the area where everyone has to stand.
During winter the temperatures are downright frigid and having heat easily helps the situation. Everyone of us keep most of the doors open while we are in production seconds plus this lets in cold air. There is a river located behind the factory and the air is Cold Plus wet plus even worse. Every one of us regularly use the gas furnace to help us at the factory with production. The gas furnace is regularly used to heat parts that we need to make out of a mold. Production has to shut down if there are any problems that keep the gas furnace from working properly. We even have a regular engineer on the staff to handle gas furnace problems. The night shift guy is not as smart as the person that works the afternoon shift, so there are a lot of times when we have to shut down production while the guy figures out the problem. Just last week, the plant was shut down because the guy could not figure out how to fix the gas furnace. The problem abruptly appeared and the furnace could not be repaired by the guy that was on night shift. We had to go home early because there was no way that we could continue with production. It was nice to get out early just because the machine broke down.
