According to 46 CFR §28.835, fuel oil piping subject to internal head pressure from diesel oil in a tank must be fitted with a positive shutoff valve at the tank. Which additional requirement applies to that valve?
- A. It must be a gate valve operable only from within the machinery space
- ✓ It must be capable of remote actuation from outside the space where the tank or piping is locatedCorrect
- C. It must be a spring-loaded valve that closes automatically upon loss of electrical power
- D. It must be located at the fuel pump rather than at the tank
Why B is correct
46 CFR §28.835(h) requires the positive shutoff valve on fuel oil piping subject to internal head pressure to 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. Operation from within the machinery space alone does not satisfy this requirement.
