Asbestos Identification and Analytical Methods
topic
Asbestos identification in bulk materials uses polarised light microscopy for mineral identification by optical properties including refractive index, pleochroism, and extinction angle according to ISO 22262 and EPA 600 methods, while transmission electron microscopy with SAED provides definitive fibre identification in air samples; phase contrast microscopy counts WHO respirable fibres in air monitoring samples to occupational exposure limit compliance.
Role
Provides the analytical methods underpinning occupational exposure monitoring, building material asbestos survey, and asbestos-containing material management planning required by asbestos regulations in countries where legacy asbestos in buildings represents an ongoing public health and occupational health management obligation for building owners and maintenance workers.
