Take rules for steam plant currently published for steam testing etc for your rules. It will save reinventing the wheel. Also,for the sake of the rep, these will show that such activities are covered by responsible authorities and responsible people, and live steam will pose little risk to the public.
tank testing is different from operating in an open public space.
1. you have to have insurance
2. the boiler must have the required test certificate
3. safety procedure must be paramount when the public are around
4. a risk assessment must be approved by the local authority
5. proof that safety procedure are adhered to when operating steam.
whilst all of these have been covered in various documents already submitted, we are at the will of people who do not/will not understand. also at tge same time tge local authority is trying to reduce its exposure to being sued by the public for allowing "dangerous practices".
i am willing to do practicable information whereby people are shown how things "should" operate, but remember we are dealing with a public authority, who while they are the driving force behind the formation of the club, are alsp the same people who can close ot down just as quick. indeed there is a whole section dedicated to just that!
