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
Operational Reactor Safeguard Examination Operational Reactor Safeguard Examination An Operational Reactor Safeguard Examination (ORSE) is an examination conducted by senior United States Navy personnel on board U.S. Navy nuclear-powered ships, specifically supercarriers and submarines. The purpose of an ORSE is to ensure that the engineering (submarines) or reactor (aircraft carriers) department of a nuclear-powered vessel is operating their reactor(s) in a safe manner. The exam also ensures the readiness of the engineering department to safely respond to nuclear power plant casualties. The ORSE board is made up of 3 junior board members (prior Engineers/Reactor Officers) and a senior board member (a prior commanding officer)
