Asbestos Insulating Board was commonly used as fireproofing material but it had many other uses such as:
Normal building items such as wall panels boards, ceiling tiles and plasterboard. It is difficult to tell the difference between asbestos insulating board items and non-asbestos materials.
Work on any type of asbestos can be dangerous. However, some short duration work (less than 1 hour for 1 person in a 7 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 1 person in a 7 day period, or more than 2 hours by all workers would require a licensed contractor.
Asbestos essentials includes a number of task sheets which will show you how to safely carry out non-licensed work on AIB.
