Abstract: A technique provides protection against unwanted conditions in wellhead structures and other structures. According to the technique, a system provides a feed through in a wellhead structure or other type of structure. The feed through may accommodate a communication line routed therethrough. A closing device is positioned in the structure at a location to enable closing of the feed through via the closing device. Additionally, a condition-sensitive device is operatively engaged with the closing device to initiate actuation of the closing device once the condition-sensitive device is exposed to a predetermined condition. Upon exposure to the predetermined condition, the condition-sensitive device initiates closing of the feed through via the closing device.
