I see no reason why trainees shouldn't have access to the CC. Any suggestions how admission to could be organised for people without a corgi number?
We could prepare a set of a dozen questions (maybe modified from the current ACS), such that anyone who got them right was serious about his gas!
Off top of my head:
1) What do you do after "stabilisation"?
2) describe two FFD's which each contain two dissimilar metals?
3) why could a case seal leak be dangerous on a negative case pressure boiler?
4) What could you do with a flue with leaking feathers?
5) When do you do a RIDDOR?
6) What's the BS on pellets?
7) What's Sulphide?
8] When might you have to measure sox and nox?
9) What drop is allowed: E6, 1¼" barrel, old flat with old carcass, no smell of gas, new boiiler?
10) What's blocked if a flame's lifting off?
11) Flue/vent problems aside, what boilers can you not put in a basement?
12) What do you do in the bathroom before doing a spillage test?
Should sort them out >
On second thoughts, some of the ACS candidates I see wouldn't get many of those
