Asbestos

Asbestos analysis of building materials, air filters and soil.

Terra Scientific offer asbestos testing services, including identification, fibre counting, and soil testing to ensure your compliance with regulations. Our expert team prioritises accuracy, efficiency, and timely results to provide you with the information you need to make informed decisions.

Asbestos Identification

Products that require testing for asbestos are commonly referred to as “Bulk Samples” or “ACMs” (Asbestos Containing Materials). Bulk samples refer to “manufactured or processed products, including solid and dust matrices, or naturally occurring materials such as ores and soils” (AS4964-2004).
Asbestos bulk material testing is an essential step in identifying the presence of asbestos in buildings and structures. The process involves collecting samples of materials suspected of containing asbestos and analysing them in an accredited laboratory.
Terra Scientific are IANZ accredited for the analysis of bulk materials in accordance with the AS4964- 2004 Method for the qualitative identification of asbestos in bulk samples.

All bulk samples need to be ‘double bagged’ before being submitted for analysis. To ensure the safety of yourself and our team, samples must be properly sealed prior to submission. Terra Scientific supply sample containers and sample bags. If you need any of these items, please get in touch with the laboratory.
Dust samples: It is Terra Scientific’s preference that dust samples are submitted on either black PVC tape or ghost wipes.

Standard turnaround for the analysis of bulk materials is 2-5 business days. Analysis of samples in 2-hour, same day and 24-hour turnarounds are also available, pending the laboratory’s current capacity and the matrix of the sample. Please contact us first if you require urgent analysis as these are dependent on laboratory availability. Urgent fees apply. Some bulk materials are unable to be analysed within 2-hour and same day timeframes due to the sample matrix. These samples include bitumastic materials and larger bulk materials that may require ashing prior to analysis.
Terra Scientific can also provide semi-quantification of asbestos and water absorption of a bulk sample submitted. It should be noted that any quantification of bulk and soil analysis is outside Terra Scientific’s scope of accreditation. We do not recommend asbestos sampling to be undertaken by inexperienced and unqualified personnel. Terra Scientific can organise sampling of potential asbestos contaminated material for you if this is required.

Asbestos Fibre Counting

“Airborne asbestos fibres are generated by the mechanical disintegration of asbestos-containing materials (ACM) and subsequent dispersion of fibres into the air from activities such as mining, use, removal and disposal of asbestos fibres and ACM. Airborne dust has the potential to contain respirable asbestos fibres.” Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres 2nd Edition, 2005
Asbestos fibre counting is an essential process used to determine the levels of asbestos fibres present in the air. It involves collecting air samples using an air monitoring pump and filter cassette, which captures airborne asbestos fibres. The samples are then analysed by a certified asbestos laboratory to determine the concentration of asbestos fibres present in the air.
Terra Scientific are IANZ accredited for the analysis of asbestos filters in accordance with Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres 2nd Edition [NOHSC: 3003 (2005)].

We aim to deliver a same day turnaround on all air monitoring samples received before 3.30pm. Samples received after this time are typically sent by 10am the next working day. 2-hour turnarounds are also available, pending laboratory capacity. Please contact us first if you require urgent analysis as these are dependent on laboratory availability. Urgent fees apply. Terra Scientific stock premade air filters which can be purchased if required.

Asbestos in Soil

The presence of asbestos in soil can pose a significant risk to human health and the environment. Therefore, it is crucial to test for asbestos in soil before any construction or excavation activities are undertaken. Terra Scientific offer both semi-quantification and presence/absence analysis for asbestos in soil matrices.

Semi Quantification

In conjunction with the AS4964-2004, the New Zealand Guidelines for Assessing and Managing Asbestos in Soil (2017) is also adhered to when undertaking asbestos soil analysis. Semi-quantification calculations are outside Terra Scientific’s scope of IANZ accreditation.
Analysis in accordance with the Western Australian Guidelines can be undertaken at the client’s request.

Presence/ Absence (P/A)

Presence/ absence analysis of soils are IANZ accredited in accordance with AS4964- 2004 Method for the qualitative identification of asbestos in bulk samples.

Soil samples can be submitted in containers or plastic ziplock bags (double bagged). At least 500g of soil needs to be submitted for semi-quantification analysis. 100g of soil is required for P/A analysis. To ensure the safety of yourself and our team, samples must be properly sealed prior to submission. We understand that our clients often require soils to be semi-quantified if samples submitted for presence/ absence return positive results. Please contact the laboratory if you require semi-quantification of samples submitted for presence/absence for guidance on sample submission requirements. Terra Scientific supply sample containers and sample bags. If you need any of these items, please get in touch with the laboratory.
Standard turnaround times for soil analysis are typically 3 – 5 business days. Analysis within same day, 24-hour and 48-hour turnarounds are also available, pending the laboratory’s current capacity and the size of the sample. Please contact us first if you require urgent analysis as these are dependent on laboratory availability. Please note that excessively sized soil samples (>1kg) take longer to dry, prepare, and analyse, and may incur an extra preparation fee.
