Due to failures in ozone converters used in the aerospace industry and manufactured in a company located in the city of Mexicali, and that generated a health problem in commercial aircraft interiors due to the malfunction of ozone converters, the internal environment was evaluated of the company mentioned and located in the desert area of the northwest of the Mexican Republic. The analysis was carried out with specialized equipment and a device for detecting and controlling chemical substances derived from sulfur and deposited on metallic surfaces of electrical connections of ozone converters installed in a section of aircraft cabins. With the monitoring equipment, the corrosive environment in the interiors of the company was quickly detected and with the development of an electrical fault detection device in the ozone converters, the failures were reduced by 70%. Microanalysis was performed using the Electronic Scanning Microscopy (MBE) technique, to identify the contaminating substances deposited on the metallic surfaces of the electrical connections of the ozone converters, as well as the concentration levels of said substances. The automated device for micro corrosion control was designed, manufactured and tested, to detect periods of deposition of sulfur-derived chemicals. In addition, specialized filters were installed to reduce the entrance to the interiors of the company in Mexicali, and thus have a regulated environment and thus avoid the generation of micro corrosion. The study was conducted from 2017 to 2018.
