US Patent 7419531 Safety system and process for its operation

A safety system for prevention of the escape of noxious media, such as explosive gas mixtures and/or ignitable substances, has at least one interception element (10; 30) which at least partly encloses and seals off a potential escape point (12) for the medium. The medium is precipitated onto the interception element (10; 30). Once the medium has been collected, it may be removed from the interception element (10; 30). In this way, both aggressive media and fuel-laden gases may be effectively controlled by safety engineering measures.
