AS 5370:2024, Sampling and qualitative identification of asbestos in bulk materials (ISO 22262-1:2012, MOD), seeks to advance asbestos safety protocols in Australia. This updated standard adopts ISO 22262 with modifications tailored for Australia, using modernising practices and aligning with global benchmarks.
Why AS 5370:2024 matters
Asbestos safety remains critical for public health and industries such as construction, mining, and land management. AS 5370:2024 replaces the now-withdrawn AS 4964-2004, Method for the qualitative identification of asbestos in bulk samples, introducing guidelines that expand testing methodologies. This shift seeks to support consistent and reliable asbestos identification, and the safety and efficacy of analytical procedures.
Key updates in AS 5370:2024
The transition to AS 5370:2024 introduces several updates to asbestos analysis:
· Advances in Polarised Light Microscopy (PLM): Building on the foundation of AS 4964, PLM remains the primary method for asbestos identification. The updated standard specifies procedures for sample preparation, mounting, and microscopic examination, aiming to enhance precision in identifying asbestos fibres.
· Inclusion of supplementary techniques: The standard incorporates Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) as optional methods to help confirm ambiguous results, particularly in complex or fine-grained samples.
· Broader analytical scope: AS 5370:2024 introduces guidelines for testing asbestos in soils and naturally occurring asbestos species, making it particularly relevant for industries involved in site remediation and resource extraction.
· Detailed sampling requirements: Protocols for sampling size, volume, and handling look to minimise cross-contamination and support accuracy across laboratories.
· Health and safety focus: Updated safety measures seek to protect laboratory personnel by incorporating rigorous protocols for personal protective equipment (PPE), safe sample disposal, and cross-contamination prevention.
Potential benefits of AS 5370:2024 for industries and public health
The publication of AS 5370:2024 seeks to deliver a range of benefits:
· Enhanced analytical accuracy: By incorporating advanced techniques and refined PLM procedures, the standard looks to support more reliable asbestos identification.
· Support for safety: Health and safety measures can support safer environments for professionals handling asbestos materials.
· Global alignment: The adoption of ISO 22262 promotes consistency in global practices and can foster confidence in Australian asbestos safety measures.
· Operational improvements: Clear guidelines and modernised methods aim to streamline processes, reducing errors and supporting efficient resource use.
Who should use AS 5370:2024?
AS 5370:2024 supports a wide range of professionals and organisations, which could include:
· Laboratories and analysts: Those conducting asbestos testing could benefit from updated methodologies that support precise and reliable analysis.
· Construction and mining sectors: Guidelines for managing asbestos in soils and bulk materials can be vital for industries addressing contaminated sites.
· Regulatory and compliance professionals: The standard provides a structured framework for asbestos identification, supporting efforts to align with safety best practices.
