Dark-light inspection of the hydrogen system

I conduct a dark-check of my hydrogen system every ten days, but no problems have been detected during these checks; basically, all fires were not discovered through such dark-checks. Please discuss whether it is necessary to carry out dark-checks on hydrogen systems.
For hydrogen-handling systems or the reaction-recovery systems in catalytic cracking, it is very necessary to conduct inspections in a dark environment. The purpose of checking with the lights off is not only to identify leak points (as it is difficult to detect fires caused by hydrogen leaks during the day), but also to determine whether the lining inside equipment with linings has come loose; therefore, I think it is quite necessary.
