A blowout preventer (BOP) safety system for testing the integrity of safety valves at the sea floor is disclosed. The system includes a BOP stack including a BOP, the BOP comprising a BOP shear ram and a first hydraulic circuit, the first hydraulic circuit in fluid communication with the BOP shear ram and having an open side and a close side. The system further includes a manifold, wherein the manifold is disposed proximate to and in fluid communication with a dump valve, a first sensor, and a supply valve and a first safety valve disposed between and in fluid communication with the manifold and the BOP on the close side, wherein the dump valve is operable to allow flow from the BOP to the manifold through the safety valve, and wherein the first sensor is operable to detect the flow from the BOP to the manifold.
