when you get twattish posters thinking that the work is so simple any idiot could do it; and then you get others questioning the point of basic safety measures
I presume you're including me in that. I never said that the work was simple; I was partly basing my comments on PPs' perceived observations. I also realise that it's very dangerous (when there is actually somebody there) and that basic safety measures are crucial. I just find it strange that all of the skills are apparently so specialised that individual workers apparently can't learn more than one of them.
Gas is obviously a highly regulated industry, but when I've had boilers replaced, it's been one man setting the boiler up, turning the water off, attaching it to the wall, drilling through for the flue, connecting it to the electric supply - even redoing brickwork. I've never know them have a team of 8 men to do every stage of it. Probably as well if each of them has to be paid a full day's wages in order to be there when it's time for their small bit.
I'm amazed that somebody has to be trained and get qualifications to know how to put cones out. I'm sure there are guidelines as to distance between cones and the angle at which a lane is gradually coned off before disappearing, but a qualification? Really? Is it like when firefighters are told they have to be trained to climb an 8-foot ladder before they can use it?
I've lived in western Europe and seen equivalent jobs being done - often at night and/or over the weekend. With my untrained eye, it always looks like a number of blokes working tobether, getting on with doing things (and I very much include carefully observing or monitoring progress and safety as 'doing things' as opposed to looking into space, scratching your arse and retuning the radio) and finishing the job quickly and efficiently. Surely they don't all have far inferior standards to us, do they? It's not even like they do a shoddy job either, as any user of the beautifully smooth Autobahn will attest.
Of course safety is crucial in a dangerous environment, and it is skilled work - but how do you explain coned-off lanes and reduced speed limits for weeks on end when you never see anybody there at all, day or night, weekday or weekend?
