Frequently asked

What qualifies as friable asbestos?+
Asbestos material that can be crumbled, pulverised, or reduced to powder by hand pressure when dry. Includes most pipe lagging, sprayed coatings, loose-fill insulation, and asbestos-contaminated soil.
Why is a Reg 64 assessor mandatory?+
For Class A friable removal, an independent Reg 64 licensed assessor must perform the clearance inspection and air monitoring before re-occupation. The licensed removalist cannot self-clear.
Can a Class B holder do Class A work?+
No. Class B licence does not cover friable removal. A Class A licence is required, and the licence holder must have completed Class A removal training and meet experience requirements.
How long before the job must WorkSafe be notified?+
HSWR 2016 Reg 47 requires notification at least 5 working days before licensed asbestos removal work commences.
Is air monitoring mandatory for Class A?+
Yes. Air monitoring is mandatory throughout Class A removal work — background, control, leak, and clearance — per Subpart 6.
