Hello
Just want to double check, cement sheeting removed using controlled methods by competent persons and waste disposed of correctly - still non licensable even though it contains crocidolite and chrysotile?

I believe you are correct aslong as you can demonstrate that you will not exceed the exposure limit. So you will have to look at the condition of it and how you were intending on removing it etc.
In effect this means that you will have to do a risk assessment however it always frustrates me when people who want advice just get that as a stock answer.
On the disposal side it will be classed as hazardous waste (England & Wales) and the premises from which is came will need to be registered with the EA.
Hope this helps,
David

You shouldn't have any problems with this as long as you follow the HSE task cards in particular A14 which explains all.
Interesting in that there is a certain company out there who swear blind that AC sheets NEVER contained Crocidolite!!!
Its not about the type of fibre but the potential for release of that fibre and AC is Low risk.

For larger scale work, you might like to refer to HSG 189/2, IMO the guidance contained in there is a bit more comprehensive than the task sheets.

I did a survey a few years ago on a MOD site. There were some garages at one barracks with AC roof sheets of the 'tell-tale' blue/grey colour. These had recently been scrubbed clean and produced a lovely blue slurry leading from the downspout to the nearest surface water drain (I informed the Adjutant straight away and thankfully he arranged for a contractor to come in and deal with it). I still have the photos somewhere!

They refuse to accept that crocidolite was used in cement? We have had loads of it come into to our lab for analysis. And you dont beleive is and all the other labs, check out MDHS 100 (are you going to argue with Bill Saunderson?).
However sometimes we will get samples of cement sheet with bright blue fibres sticking out of it and you think 'ah a bit of croc in this!'. However upon analysis it turns out to be chrysotile (white). Why? well apparently blue ase used to fetch twice the price of white years ago and so some interprising individuals soaked their chrysotile in blue dye! Human nature eh? hever changes. Some people will do anything to make a few quid.

I would add a couple of things.
Whilst for the purposes of Reg 3(2)(c)(ii) Acbestos cement is a material listed in the ACOP L143 as one in which the fibres are firmly linked in a matrix (para 34), the ACOP then goes on to state "the exceptions listed.... can be applied to most work with these materials but only when a suitable and sufficient risk assessment demonstrates that the control limit will not be exceeded."
For the RA, the ACOP also provides guidance on what a "suitable and sufficient" RA for work with asbestos should contain (Reg 6- para 67 of the ACOP- also note para 66 about competence to undertake the RA).
So I would recommend taking a look at the ACOP- lots of detail and info in there.
