David,
The Flare demos we do are hands on, we dont let them off, the people being trained let them off. WE have done these many times. And yes it would be opened up to people that have flares coming up on their expiry, or hey a couple of mates get together and split the cost and its pretty cheap to learn how to use something that may save your life. What do they cost $75 odd dollars for 2 orange and 2 red.
