Claim 0:
1. A system, comprising:
a hydraulic fracturing discharge manifold;
one or more valves operably coupled to the hydraulic fracturing discharge manifold,
wherein a plurality of additional valves are operably coupled between the hydraulic fracturing discharge manifold and corresponding ones of a plurality of hydraulic fracturing pumps,
wherein the plurality of additional valves are closable to fluidically isolate the hydraulic fracturing discharge manifold from the plurality of hydraulic fracturing pumps,
wherein the one or more valves are openable when the plurality of additional valves are closed to receive fluid flow therethrough from the hydraulic fracturing discharge manifold, thereby at least partially depressurizing the hydraulic fracturing discharge manifold to a surface location when the hydraulic fracturing discharge manifold is fluidically isolated from the plurality of hydraulic fracturing pumps, and
wherein the hydraulic fracturing discharge manifold is operably coupled between the plurality of hydraulic fracturing pumps and one or more wells;

one or more sensors operably coupled to the hydraulic fracturing discharge manifold,
wherein the one or more sensors are configured to detect one or more fluid conditions of the hydraulic fracturing discharge manifold while the hydraulic fracturing discharge manifold is at least partially depressurized to the surface location;

and
one or more controllers configured to close, or at least partially close, based on detection of the one or more fluid conditions of the hydraulic fracturing discharge manifold by the one or more sensors, the one or more valves, thereby impeding additional depressurization of the hydraulic fracturing discharge manifold to the surface location.
