OSHA's Silica Rule isn't optional. Here's what Table 1 means for concrete polishing contractors — in plain English.
⚠️ Silica Exposure Risk: Concrete grinding and polishing generates respirable crystalline silica. Without proper dust controls, exposure can cause silicosis — an incurable, potentially fatal lung disease. OSHA's Table 1 outlines the required engineering controls.
Table 1 ComplianceWhat You're Required to Do
| Task | Required Control | Required Vacuum Level |
|---|---|---|
| Handheld grinder — dry grinding | HEPA vacuum with shroud | ≥ 25 cfm at grinder inlet |
| Walk-behind grinder — dry | HEPA vacuum with shroud | ≥ 25 cfm at grinder inlet |
| Walk-behind grinder — wet | Water delivery + HEPA vac | N/A with water suppression |
| Large planetary grinder | Integrated dust collection | Per manufacturer spec |
| Polishing (all passes) | HEPA vacuum with shroud | ≥ 25 cfm at tool inlet |
