Every workplace that requires respirators has a legal obligation to provide proper respirator fit testing training. Understanding the Australian standards behind that requirement is the first step to genuine compliance. Respiratory illness caused by workplace exposure is not a minor risk. Silicosis, asbestosis, and occupational asthma affect thousands of Australian workers each year, and inadequate respirator fit testing training is consistently identified as a leading contributing factor.
This guide outlines the key standards, what they require, and how structured respirator fit test training ensures your workers are protected — not just on paper, but in practice.
The Two Foundational Australian Standards
Australia’s respiratory protection framework is built on two core standards that every employer needs to understand:
AS/NZS 1715:2009 – Selection, Use and Maintenance of Respiratory Protective Equipment governs how respirators are used in the workplace. It covers hazard assessment, device selection, programme management, and training and fit testing requirements that apply to every worker required to wear a respirator. Under this standard, all users of tight-fitting respirators must be fit tested before starting work and at least annually after that.
AS/NZS 1716:2012 – Respiratory Protective Devices sits alongside 1715 and sets the performance and testing criteria for how respirators are manufactured. When respirator use is required at work, the devices must conform to AS/NZS 1716. This is the standard that underpins the certification markings on the respirators your workers wear.
Together, these two standards form the compliance baseline for Australian workplaces — but the framework is now transitioning.
The Standards Are Changing: What’s Coming by 2030
Australia is currently in an active transition period, moving from the existing AS/NZS 1715 and 1716 standards to a new suite of internationally harmonised ISO standards. The key documents now in force or coming into effect include:
- AS/NZS ISO 16975.3:2023 — now the primary governing document for fit-testing procedures, operator competency requirements, and record-keeping
- AS/NZS TS ISO 16975.1:2023 — covering how to establish and maintain a respiratory protection programme
- AS/NZS ISO 16975.4:2024 — addressing RPE selection specifically for infectious disease outbreak scenarios
The older AS/NZS 1715 and 1716 standards are expected to be phased out by 2029–2030. Both sets remain current during the transition, but workplaces should be aligning with the new ISO-based requirements now. The main one is AS/NZS ISO 16975.3:2023, which already governs fit testing practice.
What the Standards Actually Require for Training
Under AS/NZS 1715:2009 and AS/NZS ISO 16975.3:2023, the training obligations for workers who wear respirators are clearly defined. Workers must receive formal instruction in:
- The different types of RPE and when each is appropriate
- How to correctly fit and wear their respirator to achieve an effective seal
- The limitations of their specific equipment type
- How to inspect, clean, and maintain their respirator to keep it performing effectively
- The relevant requirements of AS/NZS 1715:2009 and AS/NZS ISO 16975.3:2023 as they apply to their role
This is not a one-time induction. It is a continuing requirement as part of an overall Respiratory Protection Program which must be established and reviewed regularly by the employer.
A respirator that has not been fit tested on the individual wearing it offers no reliable protection, regardless of its classification or certification.
Who Is Responsible for Training, and Who Delivers It?
The WHS Act places the primary responsibility for providing training to workers and ensuring any RPE issued is suitable for the hazard, correctly fitted and used properly on employers and persons conducting a business or undertaking (PCBUs).
In practice, that means training must be delivered by someone with the knowledge and competency to cover both the theoretical requirements of the standards and the practical skills workers need. Generic, off-the-shelf content rarely meets the intent of the legislation. This is because training needs to be tailored to the specific hazards, equipment, and conditions workers face on the job.
Fit Test Clinic’s Respiratory Training course is built around exactly this requirement. The course runs for four hours and is aligned with both AS/NZS 1715:2009 and AS/NZS ISO 16975.3:2023, covering RPE types, correct fitting and wearing technique, equipment limitations, and maintenance. All of these are tailored to the client’s specific industry, hazards, and equipment. It is suitable for workers required to wear respirators, as well as safety officers and supervisors responsible for managing respiratory protection in their workplace.
Fit Testing: The Non-Negotiable Requirement
Fit testing is mandatory for all users of tight-fitting respirators under AS/NZS 1715, and the requirement carries over into AS/NZS ISO 16975.3:2023. There are two methods recognised under Australian standards:
Qualitative fit testing is a pass/fail method that relies on the wearer’s sensory response to a test agent such as saccharin or Bitrex. It is simpler and lower cost, but limited to certain respirator classes.
Quantitative fit testing measures the actual ratio of the contaminant inside and outside the mask, and therefore produces numerical data that is independent of the wearer’s senses and can be used with a wider variety of respirator types.
Under AS/NZS ISO 16975.3:2023, fit tests must be conducted by a competent person — someone with adequate knowledge, practical understanding, and demonstrated skill in the specific method being used. This is where respirator fit tester training becomes essential.
RESP-FIT Accreditation: The Gold Standard for Fit Testers
RESP-FIT is Australia’s national accreditation programme for respirator fit testers, developed by the Australian Institute of Occupational Hygienists (AIOH) in collaboration with industry and regulators. It is the clearest demonstration of competency available in Australia for those performing fit testing.
A RESP-FIT accredited fit tester has completed approved theoretical training aligned with AS/NZS 1715 and AS/NZS ISO 16975.3, demonstrated practical competency in both qualitative and quantitative methods, and committed to ongoing professional development to maintain their accreditation.
RESP-FIT accreditation is not a legal requirement. As things stand, the legislation requires a “competent person,” not a specifically credentialled one. However, using a RESP-FIT accredited provider is the most defensible position if your programme is reviewed by a regulator or examined in a legal context. It also ensures that the fit test was conducted in accordance with the current Australian standard, with records kept in the format required for compliance.
For those looking to perform fit testing within their organisation, Fit Test Clinic’s Respiratory Fit Tester Training Course provides the complete eight-hour pathway, covering both theory and practical competency. It is aligned with AS/NZS 1715 and AS/NZS ISO 16975.3, and designed to prepare participants for RESP-FIT accreditation.
What a Complete Respiratory Protection Programme Looks Like
Training and fit testing do not exist in isolation. Under the Australian standards, a compliant respiratory protection programme includes:
- Hazard assessment to identify airborne risks and determine when RPE is required
- Medical assessment of workers prior to respirator use, particularly those with conditions that may affect their ability to wear one
- Equipment selection based on the hazard, the assigned protection factor, and maximum use concentration
- Fit testing of all tight-fitting respirator users before first use and annually thereafter
- Worker training in the correct use, limitations, and maintenance of their specific RPE
- Inspection, cleaning, storage, and replacement of equipment at appropriate intervals
- Programme review to verify the system is operating effectively and remains current with standards
Each element of this programme depends on the others. A correctly selected respirator that fits poorly provides no reliable protection. A correctly fitted respirator worn by a worker who has not been trained in its limitations is equally vulnerable to failure.
Why Training Is the Foundation — Not a Formality
It is tempting to treat respirator fit test training as an administrative obligation — something to document and move on from. The reality is that workers who understand their equipment are far more likely to use it correctly, maintain it properly, and recognise when something isn’t right. That understanding comes from quality training, not a one-page handout.
For safety managers and supervisors, investing in proper respirator fit tester training builds internal competency that pays dividends across the entire respiratory protection programme — reducing reliance on external providers, improving the quality and consistency of fit testing, and strengthening the organisation’s overall compliance position.

Frequently Asked Questions
1. Is respirator fit testing training a legal requirement in Australia?
Yes. Under AS/NZS 1715:2009 and AS/NZS ISO 16975.3:2023, all workers required to wear a tight-fitting respirator must receive formal respirator fit testing training before starting work. This is a mandatory obligation for employers and PCBUs under the WHS Act, not a recommendation.
2. How often does respirator fit testing need to be done?
AS/NZS 1715:2009 requires that workers be fit tested before first use and then at least annually after that. Retesting is also required if the worker’s facial structure changes — due to significant weight change, dental work, or scarring — or if a different respirator model is introduced.
3. What is the difference between qualitative and quantitative fit testing?
Qualitative fit testing is a pass/fail method that relies on the wearer detecting a test agent such as saccharin or Bitrex. Those who complete respirator fit test training at the quantitative level learn to operate equipment that generates a numerical result, measuring actual leakage without relying on the wearer’s senses. Quantitative testing applies to a wider range of respirator types and is generally considered the more rigorous method.
4. Do I need to be an occupational hygienist to become a fit tester?
No. Anyone can pursue respirator fit tester training and apply for RESP-FIT accreditation — you do not need a background in occupational hygiene or safety. The key requirement is completing approved training aligned with AS/NZS 1715 and AS/NZS ISO 16975.3, and demonstrating practical competency in both qualitative and quantitative methods.
5. What is the difference between the Respiratory Training course and the Fit Tester Training course?
The Respiratory Training course is designed for workers who wear respirators as part of their role. It covers correct use, fitting, limitations, and maintenance of RPE. The Fit Tester Training course is for those who want to conduct fit testing on others within their organisation. Many workplaces benefit from both. Workers trained in correct use and an internal fit tester qualified to run compliant testing on-site.
