BS 8520-1:2009 Equipment used in the controlled removal of asbestos containing materials. Controlled wetting equipment. Specification
BS 8520-1 provides the asbestos removal industry with a specification for equipment used in the controlled wetting of asbestos‑containing materials. It promotes the manufacture of equipment and materials that will effectively wet asbestos-containing materials and suppress asbestos fibres both during and after the asbestos removal process.
BS 8520-1 specifies requirements for equipment for the controlled wetting of asbestos-containing material (ACM) by injection or spraying of liquid to suppress the release of airborne asbestos fibres.
BS 8520-1 applies to the wetting of ACM by:
- Multipoint injection of sprayed coatings, insulating board, thermal insulation and coatings on pipes, tanks and vessels
- Spraying with low-pressure spray heads of insulating board and other materials less than 10 mm thick.
BS 8520-1 is based on PAS 60-1:2004, which is now withdrawn.
