Hi Ollie
as this is a commercial show on a licenced entertianment premises that people are paying money to take part of.....
You need to look at the following
1, are you proposing to undertake audience scanning at this event
2, Do you have insurance and public liability cover to do laser shows
3, will you be carrying out a prior risk assesment of the venue
4, will you be submitting all the correct paperwork including risk assesment to the local athorities in advance to the event
5, will all the projectors meet the safety requirements
The reason i ask is .... Most proffesional laser show companies will have to follow these rules .... and as Pelosh said ... that why proffesional laser hire is expensive
if you are cutting the cost ..... you are more than likely cutting corners and could put the public at risk
i dont want to frighten you away from doing public shows but if you want do them you will have to make sure you do it properly
last thing we want is to see any forum members get into trouble
all the best ... Karl
