is this asbestos (Ed.)

[0Floz0]

Hey everyone,

Images attached. Hoping it’s just cement board but think it probably has asbestos in it. I was uplifting my floors to insulate underneath and noticed some packers made out of this as well as spare bits dotted around. Wary that they may have been cutting the boards and that’s all in the dust underneath the joists.

Just had me a bit worried. I’d appreciate any thoughts.

Thanks

Possibly, but no way to tell without testing.

Completely get that. But if it is the type to have it, is it the really dangerous type? I hear so many different things and some say it’s not much worse than Mdf dust for the less dangerous stuff.

asbestos cement board contains chrysotile asbestos fibre, considered less dangerous than the others, but its all dangerous

I would not compare it to mdf dust

theres no need to be worried unless youve been disturbing it -like clouds of dust etc

maybe wear a mask and / or you could douse the dusty areas with a fine spray of water from a garden type mister

the biggest risk is cutting it up

Thanks Notch.

Nah there won’t have been clouds. Obviously moving around is creating dust from the floor where all the dirt is. But there are only a few small pieces. A couple have been used under joists as packers and we’ve been bashing the floorboard on top of those with a hammer so may have had some movement across it. But we aren’t cutting anything.

Get a garden sprayer full of water and douse each bit before you move it.

Treat the surfaces around it similarly.

It'll dry out pretty quickly at the moment.

I’m not touching the actual stuff. It’s just near to where I’m working. Trying to go with best practise or not disturbing it but got all windows and front and back door open. Not much of a breeze though. Picture of what I’m working with attached. It’s not under every joist. Just a few of them so it’s at most about 10 packers. Then a couple of loose bits which I’m trying to avoid.

Rockwool is going in once I finish netting and then boards are going back over. I’m just wary if they did any cutting by the dirt but I can’t really douse the whole thing.

Yes it does look like asbestos cement sheet which contains chrysotile - the least hazardous type. Not AIB which is more hazardous.
It's OK left in place. Don't be overly worried about working by it or touching it, the mount of fibres that would be released miniscule and not concerning

If you want, brush some gloss paint on it.

Thank you. That does make me feel a lot better. It would make sense as I think that’s what’s been used in the soffits and along the edges under the roof tiles.

I’ve covered it all over now with 170mm of rockwool so floorboards are going back on today and I’ll crack on with the rest.

I’ve stuck all the clothes I was wearing at the time in the washer just in case. Plus used a dust mask for most of it anyway. Just got to clean all the surfaces down.
