Spent abrasive media generates fine dust mixed with substrate and coating residues. Control is essential for health, cleanliness, and waste compliance, especially where respirable crystalline silica (RCS) or combustible dust may be present.

Identify the hazard

Record the media type and any contaminants picked up during blasting—paint residues, rust, silica, or organic matter. Use this to inform COSHH assessments, RPE, and waste classification. Treat unknown legacy coatings cautiously.

Collect without re-suspension

Adopt vacuum-first methods at transfer points, under conveyors, and around separators. Avoid sweeping and compressed air. Where a combustible or explosive dust risk exists, use ATEX-rated collection with static control; Supra ATEX vacuums can be specified where the site risk assessment requires ATEX equipment.

Contain and label

Bag or drum waste at source using sealed liners. Label containers clearly and close them before moving out of the dirty zone. Keep lids on intermediate hoppers and segregate incompatible wastes.

Store and remove safely

Store sealed containers in a ventilated, signed area with spill control. Arrange timely uplift with a competent waste contractor. Keep transfer routes clean and avoid sharp turns that can damage bags.

Verify and document

Use a particulate monitor during clean-down to confirm controls are effective. Log filter maintenance, waste weights, and inspection findings. For silica-bearing waste, note the HSE WEL of 0.1 mg/m³ for RCS and ensure controls and RPE reflect this.

Practical takeaways

• Know your media and contaminants—assess and plan accordingly.
• Vacuum-first collection; no sweeping or compressed air.
• Use ATEX-rated equipment where combustible risks are identified.
• Seal, label, and segregate waste at source.
• Monitor PM and keep records to demonstrate control.

With the right collection, containment, and documentation, spent media becomes a controlled waste stream rather than a persistent dust hazard.
