textured ceiling coating containing asbestos
Rank: Super forum user
|
I have a question about the complete removal of a textured ceiling coating that contains small amounts of asbestos. I'm hoping cutting and using a trowel may allow removal of the coating in sections in a dry state by a non-licenced contractor and not notifiable, as is explained in various sections in ACoP L143. If there are problems with adhesion then a 'wet' method would be an option. For a wet method, 'Asbestos Essentials a28' describes a 'bucket and damp cloths' method: Quote:What this sheet covers This sheet describes good practice when you need to remove a small area of textured coating, eg around 1 square metre, in preparation for other maintenance work. This sheet is not appropriate for large areas. The work is still non-licensed but you need to make a risk assessment.
So I'm trying to understand the last comment..... If there are some large areas which won't peel off, if a throrough risk assessment is made/written, then IS the method a28 appropriate for larger areas, by non-licenced contractors? Or for a complete ceiling or larger areas would the spray-wetting method detailed in 'Asbestos Essentials em5' be recommended, and could it still performed by non-licenced contractors? JohnW

Since the introduction of the Control of Asbestos Regulations 2012 in April 2012, this activity now falls into the category of being “Notifiable Non-Licensed Work”. An electronic submission, using the form ASBNNLW1 must be made to the “relevant enforcing authority”. (This could be either the HSE, Local Authority or the Office of Rail Regulation). This submission must be made prior to the commencement of the activity. A copy of the completed Notification should be on site within the Site Documentation. All other requirements remain unchanged.
With the introduction of the Control of Asbestos Regulations 2006, (now CAR 2012), Asbestos Textured Decorative Coatings (ARTEX) were, controversially removed from the materials requiring to be undertaken by companies that held an asbestos license granted by the HSE. The HSE stressed however that low risk did not equate to no risk. Textured Decorative Coatings (TDC’s) are materials that have been used historically on ceilings and walls to give a decorative finish. Chrysotile (white) asbestos was used in a plaster mix approximately 2-5% by weight. When set, the material gave a hard finish that was flexible enough not to crack. These properties meant that while wet, the material could be shaped into a variety of different patterns.
Until 2006, TDC’s had been subject to the licensing regulations. However, the HSE conducted research that concluded that asbestos fibre release from such coatings was not sufficient to warrant the strict controls of the licensing regulations. As a result, when the Control of Asbestos Regulations 2006 came into force in November 2006, work on, or removal of TDC’s was no longer a licensed activity.
NOTE.
While working with TC’s has been de-licensed, it has not been de-regulated.
Would suggest that you need to contact a licensed contractor to ensure that it is done correctly

Rodger, thanks for your response. rodgerker wrote:Since the introduction of the Control of Asbestos Regulations 2012 in April 2012, this activity now falls into the category of being “Notifiable Non-Licensed Work”..... submission must be made prior to the commencement of the activity. I'm not convinced that the work will be NNLW. This is what I have read on page 21 of the ACoP L143 (2013), Quote:Table 2: Examples of non-licensable work that will NOT normally be NNLW......
.... Removal without deterioration, of textured decorative coatings (eg if the backing board is carefully cut around to achieve virtually intact removal).
and on page 22, that large scale removal IS NNLW when, Quote:Table 3: Examples of non-licensable work that WILL normally be NNLW.....
..... Large-scale removal of textured decorative coatings using steaming or gelling methods My interpretation then is that if we do the removal safely, dry and intact, or with some of the 'bucket and wet cloths' method then it won't be NNLW. JohnW

You will of course make your own mind up on what to do.
However, may I suggest that you look at the information on the HSE website regarding Notifiable Non-Licensed Work (NNLW) before undertaking this work.
Pay particular attention to the pretty little chart that illustrates what is and not "notifiable"
It states:
"Textured Decorative Coating-using gels/steam to for large-scale removal". "Notifiable Non-Licensed Works"
"Textured Decorative Coatings-only when carefully cutting around backing sheets to achieve removal intact". "Non-Licensed Work".

Yes, that's on the 'Asbestos Work Categories' chart. I suppose the bucket and damp cloths comes somewhere in between...... though I hope they could achieve removal of any 'damped' material intact and a28 does say of 'bucket and rags' : "The work is still non-licensed" So as you say, my decision or, based on my guidance/options, it'll be the designer/PC decision :) I'm considering letting them set up to do the job themselves with all the necessary controls that I will demand (enclosure, PPE, H vacuum, damp-rag clean-up, personal decontamination, statement of cleanliness) and if they find the majority of the ceiling needs damping then declare that it will now become NNLW.

John.
Your original post states "complete removal of TDC ceiling--"
Then you talk about guidance in Asbestos Essentials A-28.
A-28 is entitled "Removing TDC from small area eg 1 square metre"
Can't understand how the two can be related.

Rodger, please real all of my original posting and the question I asked. The two are related because a28 says 'This sheet is not appropriate for large areas. The work is still non-licensed but you need to make a risk assessment'. and in my original posting I'm saying: Quote: ..... I'm trying to understand the last comment .....
If there are some large areas which won't peel off, if a throrough risk assessment is made/written, then IS the method a28 appropriate for larger areas, by non-licenced contractors?
Or for a complete ceiling or larger areas would the spray-wetting method detailed in 'Asbestos Essentials em5' be recommended, and could it still performed by non-licenced contractors?

The HSE are really very optomistic to say bucket of water and damp rags are wet removal. You actually need a steamer and scraper to wet remove and this really is then a specialist task. Why not remove the ceiling complete and then re board with plasterboard. Lot of dust but not asbestos release. You may also find that the total weight of asbestos in the whole mass of ceiling takes you below the point where an asbestos licensed tip is not required. Artex removal WILL produce the need for a licenced tip and the associated costs.

Thanks Bob. Yes, too many what ifs. I don't think removal of complete ceilings is an option (several small rooms, 1 large room, total ~100sqm).
I think I will ask them to kit up someone to do a trial dry removal, see how easy the coating comes away from the ceiling.

Be careful - assuming that this is a work situation then
1) The EA WM2 changed last Oct and it is highly unlikely that you could consider textured coating as anything other than asbestos waste.
2) It is normally pure fantasy to hope that you can take the ceiling down whole.
3) The work is likely to be NNLW
4) You will need an enclosure - 2 stage etc
5) You will need appropriate training and face fit for the RPE. I think it would quite difficult to get an acceptable level of cleanliness without the use of a type H
6) The reason that the task sheet refers to doing a risk assessment is that the requirement under CAR is more detailed than the info on the task sheet
7) once done you will need a self declared clearance
Have fun.....

Thanks Bruce, Yes, this is a work situation, a refurbishment project that is F10 notifiable.
1) yes, in all my discussion above the textured coating is accepted as being asbestos waste and it's why Asbestos Essentials options are being considered; a survey with analysis was conducted. Some samples were positive some negative which is often the case with textured coating. 2) right, not an option 3) I will agree NNLW if the coating can't be dry cut and peeled off intact 4) yes 5) face fit yes; I have stated type H vacuum, can be hired from Envirog.... oops no commercial names, mod 6) RA will be detailed 7) yes asbestos essentials em10

Bob, How does this work? "you may also find that the total weight of asbestos in the whole mass of ceiling takes you below the point where an asbestos licensed tip is not required"

Well, reviewing the project again with the PC, I've decided the necessary management and advice required for the textured/asbestos removal job is beyong my competency/training.
Also the PC's site risk assessments for WAH and steel erection were so inadequate that I would need to spend at least 1/2 a day every week re-writing everything, and to also provide training, and doing site and scaffold inspections - I just don't have the time.
So if anyone can offer CDM-C and Safety Adviser services to a medium-sized business unit refurbishment, in the Coventry/Kenilworth area, please PM me and I'll pass your details to the PC. The project will last about 16 weeks April-July.

Bruce - Not as fantastic or unbelievable than the HSE method is a wet removal. It can be done and have done it many times. It is far quicker and much easier to control potential exposures.
Redken
It is all down to the EA definitions of when a material that is hazardous is in low enough proportion of the whole the and is well bound for it to be classified as normal demolition waste. The figure is 0.01%w/w from memory. Thus you can estimate the weight of asbestos from the weight of artex in total and also the total mass of the ceiling thence the %ge of asbestos in the whole. Remember you that 25kg of artex went a long long way ( around 50-70m2) and this contains less than 1 kg of asbestos. Plasterboard is between 6 and 8 kg/m2.

When I was speaking to the PC about leaving the project we did briefly discuss your suggestion/option of removing the ceiling, or removing plaster-board + coating, and it might be the option they choose. The small rooms would not be difficult with short towers, but the larger room with ~6 metre high 90 sq.m. sloped ceiling would be the real challenge.
I'm well out of this project :o)

You state that "you are well out of this project" and I can fully understand the reasoning behind your comment and actions.
However, are we not possibly heading for the position that this work will be undertaken with little or no health and safe input?
While I stated earlier that the HSE consider Artex removal as "low risk", they certainly don't consider it to be "NO RISK".
There is now a distinct possibility that this will be "a crash bang wallop job" with the artex just dumped into a general waste skip. (It does happen, I have seen it).

I suggest taking a punt on getting a sample tested. Only this week I've been surprised by negative results (plural) for coatings that I would have sworn were Artex of an age that they would be asbestos. And if you get negatives, it's been money well spent!

John,
I mentioned in an earlier post that there was a full survey published, samples had been analysed last year, some positive 3-5% and some negative. With over 100 sq. mtrs. and including a rather awkward large sloping ceiling the job needs the necessary precautions
Rodger,
They still have 2-3 weeks to make the arrangements before work should start. The site is on a large highly 'visible' 1000 acre industrial/business estate near Kenilworth where the district council and HSE have a frequent presence so I would not expect the project to proceed without the care that is necessary. The client is also resident on the estate, they own the whole estate and are spending £50M revitalising it.
I had hoped to work on this small project and get some follow-on business but I don't have much spare time to take on difficult projects, and, as I concluded, although I'm familiar with Asbestos Essentials I'm really not qualified/competent to advise on significant asbestos removal work. I expect every building on the estate will have this problem, most having been built before 1980.

And it's just as well that I came to that conclusion as just this week my PI insurance comes under review and I've noticed (been reminded.. :o) ....) that the policy excludes any work with asbestos. I have, though, enquired with the brokers about me providing Asbestos Awareness Training. I feel I always have to provide this training to ANY building contractors who work in pre-2000 buildings be they electricians, plumbers or construction/refurbishment workers. The insurance company have said they are happy to renew my policy, but added the note: Quote:We shall not be liable to pay or indemnify you against loss resulting directly from, in consequence of or in any way involving the manufacture, mining, processing, distribution, testing, remediation, removal, storage disposal, sale, use of or exposure to asbestos or materials or products containing asbestos.
The training I provide explains how to recognise asbestos, and what to do if it is encountered, and also explains that any suspicious material be treated the same way (small amounts of dust on sleeves, shoes, can be wiped off with a wet cloth, larger amounts or dust in hair requires undressing and a shower etc etc). The training also includes a knowledge test. Assuming my training is adequate any (asbestos exposure) liability should be the employer's ??? JohnW
