Well said, Brian!
It's about time that this forum became the place to exchange ideas and
opinions, without fear of being ridiculed, and with no animosity to each
other. There will always be competition and we will always think that our
product is the best, but because of this we will always strive for
improvement, which can only be good for everyone. Standards do have to be
set and maintained, because at the end of the day we are in the business of
saving lives and property, but we don't have to stand still - by putting
forward ideas, no matter how stupid they may seem to some, this will only
serve to broaden our minds and help us to be innovative - what happened to
the dinosaurs? - should we not learn a lesson here?
And will someone please come up with flexible pipe that is totally fireproo=
f
- and make it quick - I have orders waiting for them!
