I say at least 5 but using a ladder maybe 10!

Not sure how many Regs, but it only takes 1 H&S professional:

You stand there with the bulb above your head and the world rotates around you - you wish!

12. asbestos regs

if it's at work:
15. RIDDOR for when the accident happens
16. Workplace Regs to ensure that an appropriate replacement is made.
17. Employers’ Liability(Compulsory Insurance) Act 1969
18. All the environmental stuff

20. WEEEEEEEEEEEEEEEEEE!

The answer is - NONE. End of thread.

Consider yourself forgiven. Are you by any chance thinking of Bell Rock (off Arbroath & St Andrews) or Muckle Flugga at the northernmost tip of the Shetland Islands? Anyhow, if the lens assembly of whichever lighthouse is involved happens to rotate on a circular trough of mercury, COSHH might need to be considered as regards the effectiveness or otherwise of the measure to prevent mercury evaporating from the trough and lurking as a vapour inside the lamp room if it's not reasonably well ventilated. Also, if birds are attracted to the light and are killed through colliding with the windows around the lamp room, there could be an accumulation of rotting corpses on the walkway outside the windows. (Ugh!)

Also, on a note of pedantry or precision, your thread title asked about OS&H regulations rather than legislation: Therefore, any allusion to the Health and Safety at Work, Etc. Act 1974 should be discounted as an answer because, er, it's an Act rather than regulations. :-)

p.s. I couldn't resist an opportunity to mention Muckle Flugga again on this forum. One of my aspirations, for what they're worth, is to visit the light there or at least go by boat around the imposing rocky islet on which it stands.

Shouldn't there also be some sort of support group, so that you can sit down after the job is finished and talk about how it was for you?

You are all wrong! If this was a NEBOSH question, you would get 0/8. Tut tut. There ARE NO REGULATIONS "about changing light bulbs".................READ THE QUESTION! All the other regs are about other things eg COSHH, Electricty at work etc.................... A great conundrum to ask one of those clever safety so and sos we meet at branch meetings!

Ok then, the original question does not specify regulations regarding the safe installation of the light bulb, so could be taken as the need for a light bulb to be changed. That being so, it is not unreasonable to assume that light fittings are only installed where they are needed (especially emergency lighting). So if one or more was out you would be failing under “The Workplace (Health, Safety and Welfare) Regulations 1992 reg 8, where

8 (1) Every workplace shall have suitable and sufficient lighting.

And

8 (3) Without prejudice to the generality of paragraph (1), suitable and sufficient emergency lighting shall be provided in any room in circumstances in which persons at work are specially exposed to danger in the event of failure of artificial lighting.

So if one or more is not working then you potentially fall foul of this regulation. Therefore the answer is also not “None”

Don’t you just love Fridays

A bulb goes in the ground a lamp goes into a light fitting

[The ones i bought from B&Q say otherwise....and are an absolute waste of time once planted.

score - You added at #12 that the bulb is in a lighthouse in the North Sea but didn't indicate whether the lighthouse is a British one or not. If it's outwith the UK, then answering your thread title question might be difficult for most of us. Furthermore, if the lighthouse is covered by another country's OS&H legislation, most of us probably won't care unless we happen to have some involvement with whoever goes to change its bulb! :-)

colinreeves - surely midges are unlikely to be a problem because there's almost always some breeze at the locations occupied by lighthouses. At one very remote Scottish lighthouse I inspected for HSE in the late 1970s I discussed maintenance arrangements with the keepers, including how and when they repainted the metal sides and dome of the lamp room located on top of a 55m/180ft high granite tower. They explained that they used harnesses and clipped onto a series of fixed metal eyelets located on the metal structure when repainting it on an annual basis. As for timing, they said they kept such a task for one of the very few days, usually during the summer months, when there was no breeze whatsoever. It's worth adding that the standards of maintenance and OS&H at the lighthouse and others operated by the Northern Lighthouse Board seemed to be exemplary at that time.

Try living in Shetland!!! They are very resourceful midges up here ;-)

there are less H&S laws than there are environmental and tax laws

Some threads make me laugh anyway - others make me cry !
