The Two Categories of Asbestos
Asbestos, a hazardous material found in various environments, is classified into two primary groups, each with distinct characteristics and risks.
Serpentines and Amphiboles: The Two Groups
All six asbestos types are categorised into either Serpentines or Amphiboles, with Chrysotile being the only Serpentine and the most prevalent in the UK.
Serpentines: Characteristics and Risks
- Serpentines, such as Chrysotile, have curly fibres arranged in layers.
- These layers create gaps, allowing water absorption.
- Their structure makes them less resistant to water infiltration.
Amphiboles: Properties and Hazards
- Amphiboles, including the blue and brown asbestos types, have strong, straight fibres.
- These fibres form a compact structure, impeding liquid absorption.
- Their rigid composition makes them more challenging to dampen and control.
The different absorption capabilities of these groups have significant implications for asbestos management and risk mitigation. Serpentines are generally easier to handle due to their water-absorbent nature, while Amphiboles pose greater challenges due to their resistance to moisture.
