Evening

Wiring a building I need to fix some conduits to a ceiling that looks like asbestos

Do we follow the HSE guidelines for into the board

Or will I be hung drawn and left out to dry if I touch it

No asbestos register for building so I'm not sure it is asbestos

Cheers

Find out, if you can safely take a sample. Costs about £70. Or walk away if you have any doubts.

that depends on your employer
However, regardless you have a duty to think about yourself and other building users.
If there is no asbestos register, and it is a public or commercial building, someone is a bit remiss. IF its a private house, well, not surprised. What follows assumes asbestos cement, the hard board, not the furry stuff - whcih you should take far more seriously.

The HSE guidelines are a good starting point, to treat as asbestos when it isn't is safer than the other way about, but it is a slow == expensive if there is a lot of it, and it was not needed.

If there are many parallel tubes to fit, it may be better to attach something to bolt it to, be that wooden battens or unistrut, if that ends up with less holes than one per saddle clamp.

Equally if it really is a mere handful of 1/4inch holes then even some of the HSE working with asbestos guidance starts to look slightly overkill.

We can't see it so to an extent it has to be your call.

If you think it is asbestos, then you don't do anything with it.
Don't risk it as hinted at above, you can be prosecuted for working on it.
Find another route for the cables, or get the ceiling sampled to see if it is asbestos.
You cannot take a sample yourself.

Has that changed very recently then ? - under the 2012 regs, minor works with asbestos cement panel were Not Licensable work, that is did not require an approved asbestos contractor.
These then could be done by anyone capable of following good practice, the official line being that the fibres are mostly bonded, and therefore apart from a few highly unlikely activities like milling the stuff, normal works like removing or refitting a panel and small holes counted as low exposure activities so long as dust was controlled ?
It always used to be the insulating panels and cloth pads where the fibres readily detached that were considered high risk.
self sampling kits are certainly still available, where you put a bit in the envelope and send off to the lab, and they test and tell you what it is.

Who knows if it is cement board - he says "a ceiling that looks like asbestos".
Is that cement board, or soft white asbestos board? Artex with asbestos?
If it is suspected to be asbestos, you need to take appropriate precauitons, and, being as the OP isnt sure, a test of the substance is the only way to comply with the Law.
Taking samples yourself - I've always been told at the courses I've been on that you should not disturb the material unless you have the specific training to do that.

It is simpler than that. Simply ask to see the asbestos register, and if there isn't one ask for a letter stating that there is no asbestos present. The real risk of a few holes is negligible, and it is the building owners responsibility to inform you. The ceiling may be other kinds of cement fibre board, and it is very difficult to tell by inspection. Alternatively ask the building owner to arrange for another contractor to fix you a few lengths of unistruct, which takes you out of the risk route.
