Anytime work is done on any part of the gas system, or there is an occurrence that could possibly have damaged the gas system, the system should be carefully inspected and checked for leaks.
The flammable gas detector heads and control system should be tested periodically for proper operation, in accordance with the manufacturer's recommendations and the TJNAF fire safety program.
Each sensor feeding the Gas Interlock Panel should be exercised at least annually for proper operation. The interlock system itself should be tested at the same time to insure that it interrupts the supply of gas when it is tripped.
The high-pressure manifold and bottle connections should be regularly checked for leaks and damage. In particular, the CO2 system (CGA-320) uses plastic seals at the bottle connection which must be replaced periodically.
