Presentation brings a reinvigorated conversation on measurement uncertainty & how it can silently impact upon our professional work.

An overview of the lessons learned to support the management of silica dust on future demolition sites.

A look at silica risks in construction, alternative technologies for preventing dust, engineering controls and benefits of controlling dust.

This webinar provides a comprehensive update for occupational hygienists and OHS professionals on the Work Safe VIC Silica legislation.

This webinar will address the variability of health hazards associated with the processing of engineered stone. The materials science of conventional benchtop engineered stone, new low-silica engineered stone products, as well as other construction materials, will be covered. The complexity of pathogenesis and implications of recent research will be explored. Some challenges, misconceptions and future research directions will be discussed.

Winner - 2023 AIOH Conference 3M Best Paper Award. This paper discusses the controversy over the use of the linear non-threshold (LNT) model and presents the case for the existence of a threshold of effect for both asbestos and crystalline silica. The existence of threshold affect does not support the suggested need to further reduce the current OELs for these substances and others. Presented by Ian Firth

Isocyanate Resins Exposure Monitoring- 22nd March 24 Isocyanate-based polymeric chemicals are used extensively in mining and construction to fill cavities and reinforce or stabilise strata in the underground environment. Methylene diphenyl isocyanate (MDI) is a common ingredient and is a known respiratory sensitiser and skin allergen which can be inhaled or absorbed through direct skin contact. RSHQ has been investigating the adequacy of current atmospheric and biological monitoring techniques.

The panel will discuss the recent change to the welding fume (not otherwise specified) exposure standard, how can exposure to welding fumes be controlled, how can occupational hygienists help the industry understand the risks associated with welding fumes and what does the future hold with the announced Workplace Exposure Limits
