Asbestos Insulating Board (AIB)

Where do you find this?

Asbestos Insulating Board was commonly used as fireproofing material but it had many other uses such as:

  • partition walls
  • fireproofing panels in fire doors
  • lift shaft linings
  • ceiling tiles
  • soffits
  • panels below windows

What does is look like?

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.

How dangerous is this?

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.

When asbestos is disturbed or damaged, it releases tiny fibres into the air. These fibres can easily be inhaled without the person even noticing. They can become trapped in the nose or throat, or they can work their way into the lung or digestive tract. Once the fibres enter the body, this is when they start to cause health problems.
