What is the asbestos 'B' class certificate and when do I need one?

People at workplaces removing 10 square metres or more of bonded asbestos must hold a B class certificate (or bonded asbestos removal certificate). This is equal to about four standard sheets of plasterboard.

Bonded asbestos materials include asbestos cement sheeting, often called fibro, used in many Queensland buildings before 1990. The sheeting was used for cladding and roofs, and can often be found as backing boards in wet areas like kitchens and bathrooms.

An 'A' class certificate, also known as an Asbestos Removal Business Certificate, is required to remove any quantity of friable (easily crumbled) asbestos.

A person that is carrying out the removal of bonded asbestos is not required to hold a ' B' class certificate if the person:


A 'competent person' for an 'A' class certificate is not required to hold a ' B' class certificate.

Why is there a 'B' class asbestos certificate?

Any tradesperson or other worker who is required to remove significant amounts of bonded asbestos material needs to know how to do it safely.

Although a certificate is not required to remove less than 10 square metres of bonded asbestos material, all asbestos removal work must be carried out in accordance with the national asbestos removal code of practice. It's the law.

Queensland is the first state to wholly adopt national codes of practice for managing and removing asbestos, which is the most effective way of minimising the potential exposure to asbestos.

How do I obtain a 'B' class certificate?

To obtain a 'B' class certificate an applicant (or employee of an applicant) has to demonstrate they are familiar with the practices and procedures for removing bonded asbestos material that are set out in the National Code of Practice for the Safe Removal of Asbestos 2nd Edition [NOHSC:2002 (2005)] (non-Queensland Government link) as stated in Information Paper AR3: Approved criteria for a certificate to perform work to remove bonded asbestos containing material (PDF, 34 kB).
