46 CFR §28.835(h) requires that the positive shutoff valve on fuel oil piping subject to internal head pressure be capable of remote actuation from outside the space in which the tank or piping is located, be accessible at all times, and be suitably marked. The regulation does not restrict remote actuation to the wheelhouse, nor does it require automatic actuation.
