You don`t need a radio tire truck. You need a SOUND TRUCK with an AIR
HORN to get the audience`s attention to listen to the message.

Amen to that Richard.
I also question the wisdom of transmitting RF in a hazardous chemical
spillage area.

That is not on our side of the table though. How this sytem is ultimately
used is out of our hands.

I have seen these systems and they have failed to do two things.

Be heard in a modern car with loud radio and great insulation and 2) pass
the populace acceptance test.

And you've offered this is during an obvious emergency? :
1 Why would they play music loudly in an insulated car when doom is
on their heels?
2 Why would neighbors complain of noise telling them they were about
to be die?

Richard's description adequately suits:
Local - that would reach out approximately 1 mile and "overbroadcast"
to those immediately in danger within a stationary site.

Your objections are more tailored to suit your solution than the
problem.

The acoustic testing has been done, yes, and the PA is obviously intrusive
to the nth degree and is not a panacea for all emergency commo.

1 Why would they play music loudly in an insulated car when doom is
on their heels?

Because they haven't yet been informed, perhaps.

2 Why would neighbors complain of noise telling them they were about
to be die?

It's not always a "death or flee" scenario, it could be hazardous but not
deadly.

I have a client who is much more knowledgeable in these situations than I
am, maybe even you. It's a custom build, not an Ari build.
