I am hoping someone can advise me on the PPE and LEV requirements for intermittent drilling of MMMF (Carbon Fibre) as in repairing damaged panels and fitting of subsidiary equipment.

I believe MMMF dust it classed as nuisance dust,so the odd hole with dust not falling directly into the face would not be regarded as a significant risk. If higher work rate or dust likely to enter breathing zone then as sensible precaution FFP3 mask correctly face fitted. If product is RCF (cat 2 carcinogenic)for obvious reasons be more cautious & the mask for all but the smallest simplest job should be used.

Trying to be helpful but just another thought after posting and reading your question again I am not sure if carbon fibre has a sepatate classification to the generic MMMF

I have a device I acquired in Germany, in a DIY store, intended to limit the amount of dust created when drilling into plaster, brick, etc. It simply attaches to a vacuum cleaner. The vacuum cleaner is switched on, the device placed on to the surface to be drilled. The drill is then inserted into a hole in the device and any dust is drawn away. It works a treat, but I have never seen anything similar in the U.K.
However, it would not be difficult to fabricate something similar and this would be a simple means of controlling dust from drilling.

Thanks Chris, yes I have also seen these on sale in UK DIY stores. What then would we need in the form of a compliant vacuum cleaner? (What filter/bag/dust collector should we use?) I am assuming that the dust collected would have to be disposed of through a controlled waste procedure.

I would not suggest a standard vacuum cleaner for an industrial application, but would contact one of the suppliers of LEV systems. Almost certainly one of their smallest units would suffice, probably with a simple filter.
As far as disposal is concerned, I am no expert, but I would have thought that as this is an inert material no special arrangements would be needed. However, again I would check this with a specialist in this field. No doubt someone on this forum will be able to comment.

Ask the manufacturer.
If they get stroppy ask to speak to their H/S department. If they make the stuff they will have the knowledge etc for working or re-working the material.
Crack on.
