The Difference Between Friable and Non-Friable Asbestos
Asbestos is a hazardous material, but not all asbestos-containing materials (ACMs) pose the same level of risk. Understanding the difference between friable and non-friable asbestos is essential for safe handling and compliance.
Friable Asbestos
- Definition: Can be easily crumbled or reduced to powder by hand.
- Examples: Sprayed asbestos insulation, loose-fill asbestos, some ceiling or wall coatings.
- Risk: Fibres are easily released into the air, making inhalation highly dangerous.
- Regulatory requirement: Removal usually requires licensed asbestos removalists.
Non-Friable Asbestos
- Definition: Bonded asbestos that cannot be easily crumbled.
- Examples: Asbestos cement sheeting, vinyl floor tiles, roofing sheets.
- Risk: Fibres are less likely to become airborne unless the material is cut, drilled, or sanded.
- Handling: May sometimes be managed in situ with proper controls, but disturbance still requires risk assessment.
Key Takeaway
Friable asbestos is high-risk and strictly regulated, while non-friable asbestos is generally lower risk but still dangerous if disturbed. Engaging an occupational hygienist ensures proper identification, risk assessment, and management to protect workers and comply with NSW WHS laws.
