Petro-Hab’s economical ATEX certified Safe-Work™ Modular Control System (MCS) provides a safe work environment within Zone 2 rated hazardous locations. This system is integrated into the Petro-Habitat in the same way as the ATEX Zone 1 rated Safe-Stop™ Modular Shut Down System, but eliminates the extra services, and costs required for Zone 1 rated areas.
