[PSUBS-MAILIST] venting batteries

[hank pronk]

Vance,
I get that for sure, it just seems logical to vent the battery directly.  What am I missing here?  Why vent the Hydrogen into  a space then vent the space, makes no sense.

Hank,
The vent system should be used for half an hour prior to charging to clear the keel, then throughout the charge and finally for another half to one hour afterward. What the maintenance log does not say is that somebody forgot to turn on the LP supply air during a charge. It happened once on Delta, too. Bang! Her deck plates all have a slight upward bulge as a result. Oops.

Steve, 
>I am thinking interior of the hull.  Gamma has interior batteries sealed in a box.  There is an air system to purge the box after charging.  When I was reading the daily service reports, I read about an instance where the box had an explosion due to a faulty cable connection.  I was thinking of going one step further and drilling in vent tubes in the sealed caps to carry the hydrogen away.  I am not sure if this is a good idea or not, seems simple and effective.
