Generate a risk assessment for construction dust and silica exposure in the UK. Covers COSHH, RPE selection, dust suppression, and health surveillance for silicosis.
Frequently asked questions
- What is the workplace exposure limit for silica?
- The WEL for respirable crystalline silica is 0.1 mg/m³ as an 8-hour time-weighted average. This is a legal limit that must not be exceeded.
- Do workers need health surveillance for dust?
- Workers regularly exposed to silica dust above the action level should be under health surveillance including lung function testing (spirometry) at regular intervals.
- What RPE is needed for silica dust?
- For cutting and grinding concrete or stone, an assigned protection factor of at least 20 is typically needed — an FFP3 disposable mask or a half-face respirator with P3 filters. Workers must be face-fit tested.
