The factory produces semi-trailers and buses. It’s just a factory—big, with cranes, warehouses, carts, blanks, sawdust, noise, and workers. Dirty windows in the workshop ceiling, powerful lamps. A laser cutting machine. It needs a large refrigerator. There was a significant leak, but it was fixed before we arrived. We came to check on things. Since the installation is large and there’s no way to evacuate the freon, we couldn’t check the quality of the circuit with a pressure test. So, we used an electronic leak detector. We also wiped up the oil that had leaked during the incident. Everything is in order.
