Arrangement for releasing highly volatile substance into closed volumes has reservoir containers for volatile substance in e.g. bounding walls, valves on reservoir containers, actuator

摘要

The arrangement has reservoir containers for the volatile substance in the walls, ceiling and/or floor bounding the enclosed space, valves on the reservoir containers and an actuator for opening and/or closing the valves. The actuator is located outside the closed space and is protected against unintentional valve opening. A detection device checks the authority of the person operating the actuator.
