They should have learned from Australia!

Phenomenal !! The Chinese certainly take a longer term view of investments than 'we' do (when the Politicians are looking only at will give a quick return) You have to have respect for their technologies. Shame other aspects of the country are less wholesome.

And that's a principal going back to Victorian times - maybe we should re-introduce the "Workhouse", where the poor can live, work and earn a copper or two.

When I fitted the new kitchen in the camper, the "Gas Man" said I needed bigger holes in the floor, a bigger hole in the gas locker floor, and a CO alarm (no mention of a Smoke alarm, but I fitted both.

Budget ?

One of the early uses of Raddle was to show if a ewe had been covered - still in use today. The raddle was/is held in a small container on a chest harness worn by the ram, when he mounts the ewe the raddle rubs off and leaves a mark on the ewes back,the shepherd could then note the date, and when the time came, make arrangements for her containment. The 1st known (written) records for the use of Raddle (Ruddle in some places) as markings for sheep goes back to 1648 1648 I marked my sheepe, 101 ewes of my owne with fresh redle on the narr sholder, (Thurlstone) 1669 a fat Wether out of his Croft, marked with raddle on the head, one Eare slitt the other cropt, (Sheffield) 1688 one other sheep ridled on the head, (Kilnsey) 1701 a raddle marke along the Rigg, (Skipton). The varied spellings are found also in minor place-names: Raddlepits, Riddle Clough, Riddle Pit.

C&RT do say that it is suggested that having to be in a fixed location for work / school/ doctors etc is not really possible whilst meeting CC requirements. It depends on how much inconvenience you are prepared to suffer.

I'm guessing that she thinks it requires an electrical switch, and doesn't understand that something like a manually operated T-valve is required to be put in the pipe lines (DIY or by a plumber) Something like this would do the job.

I said (or maybe implied) that if the ISO standards were up dated to include the various types of Li batteries and detailed the correct methods of installation, THEN they could be used to check compliance. Yes - you are repeating again what I said "the current standards just say 'refer to manufacturers recommendations'".

So you are agreeing with me ? The RCD inspectors are very experienced, multi discipline engineers - they have to be they are signing off everything from the strucual steel and welds to the gas, fuel and electrical systems

The part 2 is the one approved for boats, but, when the BSS first came out they did not seem to know there was a Part 1 and a Part2 and were happy with Part 1 alarms being fitted - now they are stuck with them until they break / wear out which is why they say replace them with the Part 2 alarm.

Currently narrowboats have an exemption in the RCD/RCR in that the builder is able to sign-off compliance. Other categories of boats are required to have an RCD/RCR approved surveyor sign-off the boat. Mabe it is the time to have the canal boats exemptions removed and the boats signed-off by 'competent' inspectors (ie not BSS examiners) The RCR/RCD has detailed ISO specifications, which, if installation is in accordance with those specs, it gets the automatic certificate of compliance. If the boating ISO standards are up to date & cover the latest technology it shouldn't be an issue. Currently the norm is for the standards to say "should be installed in accordance with the manufacturers requirements". Nothing will stop 'tinkerers' and "I can do it better" boaters from fiddling about and changing settings post purchase.

The installation instructions are pretty clear - they should not be installed on the celing, or at height' as there is a dead-air-space. They should (ideally) be installed at head height, when lying down, as that is the air level you are breathing when asleep and, most unlikely to notice you are being poisoned. Smoke rises - so the ceiling is the place for a smoke alarm. CO is virtually the same weight as 'air' and it is said, "floats around" generally between waist & shoulder height
