Drilling into non-friable asbestos using a thickened substance to control airborne fibres and dust

This safe work procedure describes the safe work procedure for drilling holes into non-friable (bonded) asbestos-containing material (ACM) such as fibro, hardiplank, compressed sheeting and tilux using a thickened substance (such as shaving foam) to control airborne fibres and dust.


A range of equipment should be used to control the risk of exposure to airborne asbestos fibres, including:

  • 200 μm plastic drop sheets
  • rolls of duct or gaffer tape
  • plastic bags 1200 x 900 mm (200 μm) with a warning label (e.g. CAUTION: Asbestos, Do no damage or open bag. Do not inhale dust.)
  • warning signage
  • barricading or hazard tape
  • bucket three-quarters full of water
  • atomiser bottle with water
  • access to a continuous supply of water
  • cordless drill or hand drill
  • drill bits suitable for the task
  • tape measure
  • clear disposable cups
  • thickened substance eg. shaving cream or hair gel
  • rags or disposable wipes
  • PVA glue (or other sealant) and a small paint brush
  • marker pen
  • access to a first aid kit
  • spare PPE
