Gas Safety Core Revision Guide - Domestic UK: CCN1, CENWAT, MET1 training for ACS (ACS Gas Knowledge for Trainees and Reassessments)

Concise and to the point does not go too much into detail, made me confident for the re-assessment that is coming soon.

I Literally just opened the page at combustion performance and seen glaring mistakes. First the maximum ratio allowed is 0.004 not 0.008 which is about 800ppm!! If you left that at 0.008, that’s riddor and a visit from the hse, also chance of killing someone if it leaks, jailed. Second, The highest allowed ppm is 400 not 350. I’ve not bothered to look anywhere else in the book. Deleted it, complete waste and the author is a clown. Digest it for your test and your failing lol
