TOI was busted multiple times for the state of the vents/fire dampers on many of their ships/semi’s and have had a few of their ships go on down time until ALL vents were 100% - we heard a story about a ship where, during a USCG inspection, was asked to function a few theirs…one inspector was going to be on the bridge at the panel an one locally at the vent…the C/M actually sent an AB with the inspector to the vent with a rubber mallet to make sure he could beat the vent shut if he had to…with the inspector witnessing. Unfortunately, HVAC systems in general and fire dampers/vents in particular seem to be given the least amount of attention while in the design phase. I’ve always had the policy that no matter where you are, who you are with, etc, that vents thrive on attention and need a bit of Kryoil sprayed on their moving parts ever single time you look cross eyed at them, which keeps you out of trouble and from having to spend a lot of time of them…because no matter what you do, especially if you DON’T give them a lot of attention, you are going to spend a lot of time and money eventually anyway.
