Silica (RCS) Exposure Control Plan
Respirable crystalline silica exposure control plan for grinding and preparing concrete substrates before membrane application, meeting the crystalline-silica-substance duties in force from 1 September 2024. On-tool extraction and water suppression controls, air-monitoring triggers against the 0.05 mg/m³ WES, and review schedule.

About this document
Grinding and preparing a concrete substrate before a membrane goes down generates respirable crystalline silica — dust fine enough to reach deep into the lungs and invisible in the air. Processing crystalline silica substances carries specific duties that came into force on 1 September 2024, including a written exposure control plan for high-risk processing.
This plan identifies the tasks that generate silica and sets controls in hierarchy order — on-tool H-class dust extraction or water suppression, never uncontrolled dry cutting, restricted access and no dry sweeping. It specifies the respiratory protection program including fit-testing, sets air-monitoring triggers against the workplace exposure standard of 0.05 mg/m³, records results and the actions to take if that standard is exceeded, and defines the review schedule.
