Asbestos identification: residential renovations guide

That article covers the complete process including:

  • When identification is required (pre-1990 trigger, disturbance rule)
  • The two compliant paths under WHS Regulation 422: competent person survey or presumption rule
  • Common ACM locations by building element (fibro cladding, eaves, vinyl floors, pipe lagging)
  • Bulk sampling procedure and NATA-accredited laboratory requirements
  • Documentation minimum for residential sites
  • Removal licensing thresholds (Class A vs Class B) and clearance certificate requirements
  • Common compliance holds that attract stop-work notices

Quick summary

Any residential building built or renovated before 1990 is likely to contain asbestos-containing materials (ACMs). Before disturbing any suspect material you must either have a competent person identify ACMs, or assume all suspect materials contain asbestos and manage them accordingly. Sampling must go to a NATA-accredited laboratory. Removal over 10 m2 of non-friable ACM requires a Class B licence; any friable asbestos requires Class A.

The full process, worked through step by step, is at Asbestos identification: residential renovations guide.
