An electrical machine such as an alternator has a first fan and second fan rotatably disposed within a first housing portion and a second housing portion. A rising pipe arrangement is arranged in the interior of the cladding tube and is connected, in the vicinity of the first base, with an outlet which is guided outward for the product resulting from the catalysis of the process medium. In the safety program definition phase, a safety program is thoroughly defined through the generation of system safety plans and the establishment of the safety team.
