A protective device includes a pipe in a pipe system for transmission of a flow of a fluid from an upstream end of the pipe system to a downstream end of the pipe system. The device includes a pipe insert, disposed within the pipe system between the upstream and downstream ends. The pipe insert has a cylindrical body. A valve is within the pipe insert and is moveable between open and closed positions. The open position opens the pipe insert, enabling transmission of the flow of the fluid, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid. A sensor is within the pipe insert for disposition within the flow of the fluid to detect a target compound in the pipe insert. The valve moves from the open position to the closed position when the sensor detects the target compound.
