How dangerous is this?
Work on any asbestos can be dangerous. However, some short-duration work (less than 1 hour for one person in a seven day period, not to exceed 2 hours spent by all workers) for small or minor tasks on AIB can be carried out by non-licensed workers who are appropriately trained.
Short duration work to remove AIB as part of demolition or major refurbishment would be notifiable.
Any work lasting more than 1 hour for one person in a seven day period or more than 2 hours by all workers would require a licensed contractor.

We recommend samples of this material are only taken by a suitably trained person
