Abstract
A safety system for connection to a toxic gas detector and a toxic gas producing engine, and its operating method, includes an interrupt device coupled to connections to the detector and the engine. The interrupt device includes a toxic gas signal detecting circuit and a circuit for permitting starting of the engine. The detecting circuit activates the permitting circuit if the toxic gas signal represents a toxic gas concentration below a predetermined level. In one embodiment, the permitting circuit is activated if the safety system is healthy and fully functional. Similarly, a safety system for connection to a toxic gas detector and a toxic gas supply, and its operating method, includes an interrupt device coupled to connections to the detector and the toxic gas supply. The interrupt device includes a toxic gas signal detecting circuit and a circuit for permitting of flow from the toxic gas supply. The detecting circuit activates the permitting circuit if the toxic gas signal represents a toxic gas concentration below a predetermined level.
