1 Use the right kit
  • Cover work area with plastic sheets secured with tape to help catch waste
  • Wear a disposable, correctly fitted FFP3 face mask and Type 5 disposable overalls
  • Wear the overalls one size too big and put the legs over the top of footwear
  • Do not re-use disposable overalls and masks
2 Keep dust down
  • Put masking tape on both sides (if possible) of the asbestos cement where you are drilling to stop it crumbling
  • Put a blob of wallpaper paste or shaving foam on both sides (if possible) where you are going to drill
  • Drill through the paste/foam
  • If you are running cables through the hole, make it large enough so that the cables pass through easily
  • Remove the masking tape and use a damp cloth to wipe off the paste/foam
  • Wipe the drill bit
  • Put the used cloth and masking tape in a plastic sack
  • Put sealant around the hole
  • If you are running cables through the hole, use a plastic sleeve
  • Use a manual drill if possible, otherwise set your power drill to the slowest speed.

3 Clean up properly
  • Use a damp cloth or Class H vacuum cleaner with a special filter to clean up
  • Do not use a domestic vacuum cleaner or a brush as these will spread asbestos fibres into the air
  • Double bag all waste including masks, overalls, cloths and plastic sheets in plastic sacks, seal with tape and label as asbestos waste
  • Contact the local tips in your area to find one that accepts asbestos waste
