Some of you may find the following of interest.
When I took my Coxwain's and during our fire fighting practicals they asked for us to bring in any old flares we had and we could fire them at the facilities in a safe manner. So lots of us brought outdated flares. We put turn out gear
(bunker) on and face shields after a visual was checked and fired them off.
Several of smoke, red, some parachutes a few whites etc were fired. None failed. But the most interesting was a fellow brought in a pack that were I believe from early 1980's looked to have been wetted at one point at least a bit but relatively in okay shape. So they rigged it to fire from a remote
pull just in case but it worked fine.
Lots of the ones we were letting off were well over 10years old and on that day their was not a single
failure. Of corse we were on dry land at the time and Murphy that sneaky bastard was no where to be found or maybe be was helping them go off.
Anyway I thought it was interesting. (BTW they were done in a fire fighting mine safety
As to the comment of them not being of any use because of the reaction they instill I think that is totally dependent on the situation.
Just let off a flare with nothing else and its true maybe not much will happen.
But have you ever watched I shouldn't be alive? The amount of times people can see the rescuers passing for days but are not found is staggering. If they had a flare it could make all the difference.
Having led flares that are compliant may work but they are directional at least the ones I've seen where as a flare is omnidirectional relatively stable, reliable even out of date in an emergency
and doesn't have any batteries corroding inside (I'd definitely want a lithium stable non leaking corrosion
proof connected and sealed battery
assembly in one.)
At any rate the energy stored and released in a flare will be hard to surpass with batteries. Wash up on shore somewhere and a flare can ignite a signaling fire fairly quickly too.
