Electrical safety testing that all connections are sound. Live testing Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified RCD testing: on modern electrical systems RCD’s and RCBO’s are regularly fitted, these devices react to electricity missing from the circuit or installation such as when a person is receiving an electric shock as the electricity passes through his body to the ground (earth). The competent person will then issue an Electrical Installation Condition Report (EICR) also known as Periodic
USNS Safeguard (T-ARS-50) up to 1,000 gallons per minute of seawater or aqueous film forming foam (AFFF) When originally built, "Safeguard" had a fourth remotely controlled fire monitor mounted on her forward kingpost, but this was later removed. "Safeguard" has a 3,600-gallon foam tank. In addition to the equipment carried by "Safeguard", the US Navy Supervisor of Salvage maintains a stock of additional emergency fly-away salvage equipment that can be deployed aboard the salvage ships to support a wide variety of rescue and salvage operations.
