Abstract: A lockout device to secure access to a pipeline valve through a utility valve box having an inwardly directed ring is described. The lockout device includes a tube with a shackle, a plate with an opening, and a lock. As installed, the tube fits within an interior space of the utility valve box. The lock locks the plate and tube together. The width of the plate is greater than the inner diameter of the ring.

Abstract: An underground vault security system. The security system includes a portal covering which is capable of being latched, a fluid-operated latching mechanism, and a wireless communication device. The communication device sends signals to a solenoid valve to allow fluid from a fluid source to be transported to the piston to retract the bolt and allow the portal covering to open. In one embodiment, the communication device also sends signals to the solenoid valve to allow fluid from the piston to return to the fluid source, allowing the bolt to extend into and lock the portal covering. In another embodiment, a cable is attached to the bolt and pulled through a one-way ratchet assembly to lock the portal covering.
