I have two of the banners, one is the 6 inch and the other is a 12 or 16
inch.  I found them on sale because they, like flares, have expiration
dates.  Since I carry other devices to meet my obligation to have current
daytime devices and I don't think the banners will, with age, have an
increased probability of failure, on long trips, I keep one attached to the
stern of my boat as a safety device.

Really?  What expires?  Does the fabric dry rot or something?

Probably the orange dye in the banner fades over time, as do most dyes, and
the color gets "out of specification". I suppose they last a bit longer than
flares though. Anybody knows?

I don't see anything that will expire.

The banner appears to be international orange polyethylene.  It is contained
in a black tube until used.  The banner is held open to width and given
additional floatation by small diameter plastic tubing.  The dye in the
plastic is probably not light stable, but until the banner is used and
exposed to sunlight for a long period, that is not an issue.

Hi all,

my previous post about the orange dye in banners fading over time might not
have been entirely correct, although some other ageing mechanisms may apply
(plastic becoming brittle or sticking together, tubes leaking). The
manufacturer should know best how long his products are supposed to be
useable, especially under "non-optimal" conditions, and he puts on a date
accordingly (I suppose).

Anyway, I think it is sensible that ALL safety related equipment is labeled
with an expiry date. This way, you are forced (or at least encouraged) to
inspect it periodically, and see if it is still useable. 

happy (and safe) paddling,

    Kees
