Airborne asbestos

Any fibres of asbestos small enough to be made airborne. For the purposes of monitoring airborne asbestos fibres, only respirable fibres are counted.


The asbestiform varieties of mineral silicates belonging to the serpentine or amphibole groups of rock forming minerals, including actinolite asbestos, grunerite (or amosite) asbestos (brown), anthophyllite asbestos, chrysotile asbestos (white), crocidolite asbestos (blue) and tremolite asbestos or a mixture of any of these. 


Asbestos containing material  (ACM)  

Any material or thing that, as part of its design, contains asbestos. 

Asbestos-contaminated dust or debris (ACD)

Dust or debris that has settled within a workplace and is (or is assumed to be) contaminated with asbestos. 

 Asbestos related work 

Work involving asbestos other than removal work.  Includes sampling and identification, maintenance and service work on non-friable asbestos or ACM, transport and disposal, demonstrations and training and mining for non asbestos minerals. 


Competent person (asbestos management)

Someone with knowledge and skills of the asbestos removal industry practice through training and experience (e.g... license holder, removal supervisor, removal worker). They should also hold specified VET certification for asbestos or tertiary qualifications in OHS, occupational hygiene, science, building, construction, or environmental health to carry out asbestos assessor work. For all other purposes, competent person means a person who has acquired through training, qualification or experience, the knowledge and skills to carry out the task. 

Friable asbestos

Material that is in a powder form or that can be crumbled, pulverised or reduced to a powder by hand pressure when dry, and contains asbestos.  

Non-friable asbestos

Material containing asbestos that is not friable asbestos, including material containing asbestos fibres reinforced with a bonding compound, often called bonded asbestos. Please note, sometimes non-friable or bonded asbestos can become friable (e.g. via weathering, abrasion or fire). 


A person carrying out work for a PCBU including employees, contractors, subcontractors, outworkers, apprentices and trainees, work experience students, volunteers and PCBUs if they perform work. 

Health and Safety Representative (HSR)

Elected by their work group to represent them on health and safety issues (replaces the term ESR). An HSR may also: monitor the compliance of the PCBU with Work Health and Safety Legislation and regulations, investigate complaints from work group members about work health and safety matters inquire into anything that appears to be a risk to the health or safety of work group members inspect the workplace at which work group members work, after giving reasonable notice to the PCBU. (An HSR can inspect the workplace without giving notice, in the event of an incident or a situation involving a serious risk to the health or safety of a person emanating from an immediate or imminent exposure to a hazard) accompany an inspector during an inspection of the workplace, or part of the workplace, at which a work group member works, and if they have completed the required training, direct a work group member to cease unsafe work and issue a Provisional Improvement Notice (PIN). If it is safe to do so they should consult with the PCBU first.  There is no obligation to consult if the risk is so serious and immediate.


Person conducting a business or undertaking (PCBU)

The Work Health and Safety Act 2012 no longer uses the term  ‘employer’ recognising that there are many different types of working relationships in the modern workplace, not just the traditional employer/employee relationship. PCBU includes a person conducting a business or undertaking alone or with others, whether or not for profit or gain, including as a partnership, self-employed person and as an unincorporated association.
