Claim 4:
5. A method, comprising:
at least partially depressurizing a hydraulic fracturing discharge manifold to a surface location when the hydraulic fracturing discharge manifold is fluidically isolated from a plurality of hydraulic fracturing pumps, said hydraulic fracturing discharge manifold being operably coupled between the plurality of hydraulic fracturing pumps and one or more wells,
wherein at least partially depressurizing the hydraulic fracturing discharge manifold to the surface location when the hydraulic fracturing discharge manifold is fluidically isolated from the plurality of hydraulic fracturing pumps comprises:
opening one or more valves, operably coupled to the hydraulic fracturing discharge manifold when a plurality of additional valves are closed, the plurality of additional valves being:
operably coupled between the hydraulic fracturing discharge manifold and corresponding ones of the plurality of hydraulic fracturing pumps; and
closable to fluidically isolate the hydraulic fracturing discharge manifold from the plurality of hydraulic fracturing pumps,

and
receiving fluid flow to the surface location from the hydraulic fracturing discharge manifold through the one or more valves;

while at least partially depressurizing the hydraulic fracturing discharge manifold to the surface location, detecting, using one or more sensors, one or more fluid conditions of the hydraulic fracturing discharge manifold; and
based on detecting the one or more fluid conditions of the hydraulic fracturing discharge manifold using the one or more sensors, impeding additional depressurization of the hydraulic fracturing discharge manifold to the surface location,
wherein impeding additional depressurization of the hydraulic fracturing discharge manifold to the surface location comprises closing, or at least partially closing, the one or more valves.
