On-Tool Dust Extraction Systems
On-tool dust extraction captures dust at source by connecting a vacuum extractor directly to the power tool through a shroud or integrated port. This is one of the most effective controls for silica dust when cutting, drilling, chasing, or grinding concrete and masonry. The HSE requires that dust is controlled at source wherever practicable, and on-tool extraction combined with the correct vacuum class significantly reduces worker exposure. The system only works if it is properly maintained, correctly connected, and the filters are regularly cleaned or replaced.
- Connect the on-tool extraction system to every power tool before starting any cutting or grinding task.
- Use an M-class vacuum extractor for medium-hazard dust and H-class for silica and asbestos dust.
- Check the vacuum hose connections are secure and free from blockages before starting work.
- Clean or replace vacuum filters at the intervals recommended by the manufacturer.
- Empty the vacuum dust collection container regularly and dispose of contents as hazardous waste.
- Never disconnect the extraction system to speed up the task or because it feels inconvenient.
- Inspect the extraction shroud or hood for damage and ensure it covers the dust generation point.
- Monitor the vacuum suction indicator and stop work if the performance has noticeably reduced.
- Combine on-tool extraction with water suppression for maximum dust control on high-exposure tasks.
- On-tool extraction captures dust at source and is one of the most effective controls available.
- M-class vacuums are the minimum for construction dust; H-class is required for silica and asbestos.
- A blocked filter dramatically reduces suction and allows dangerous dust to escape into the air.
- Never remove the extraction to work faster — a few minutes of unprotected exposure can be harmful.
- Dust collected in the vacuum is hazardous waste and must be disposed of through the correct route.
- Combining extraction with water suppression provides the best possible dust control during cutting tasks.
