There is an HSE book concerning working with asbestos. It has generic risk assessments and method statements for almost every situation you could come accross.
IIRC there is a similar process in there to what I have dscribed. I suspect the only thing it mentions that I have not is perhaps the use of water or special vacuum to contain dust whilst drilling.
Having said that Farlo would just want to use extra long plasterboard screws to hit the battons if that's what the sheet is fixed against. No drill needed for these.
If he has to go into masonery then on reflection I would advise him to dampen the area to be drilled with water, then use a specalist vacuum cleaner (special filter) that can be hired for this job.
Just to be absolutely squeaky he may seal the edges/joins of the plasterboard with mastic.
