Approved automatic or manual shutoff valves shall be provided where the transfer hose connects to _________ piping.

Approved automatic or manual shutoff valves shall be provided where the transfer hose connects to _________ piping.

• A. Process piping
• B. Storage piping
• C. Vent piping
• D. Drain piping

Answer: (A)

When transferring product, you need a clear, immediate way to stop flow at the point where the hose meets the system. Placing an approved automatic or manual shutoff valve at the connection to process piping provides a rapid isolation point so a leak, hose failure, or backflow can be contained right at the entry to the processing system, minimizing spills, contamination, and potential overfills. This valve is specifically about the flow path into the system, not the other paths like vent, drain, or storage lines. Vent piping handles vapors, drain piping collects liquids for disposal, and storage piping leads to tanks; none of these are the active route for the transfer into the process system, so they aren’t the appropriate places for this shutoff requirement. Having the valve on the process piping side gives a reliable, immediate stop to flow during a transfer operation.
