Overview
Crystalline silica is the hazard that defines stone carving as an occupational risk. Respirable particles are far too small to see and stay airborne for hours. The damage is cumulative and irreversible, and it does not announce itself until it is advanced. A half-mask with P100 filters is the working minimum for any dry stone operation.
Using it
- A P100 half-mask is the sensible default for stone. Disposable P95 masks are a fallback, not a plan.
- Do a fit check every time: cover the filters and breathe in. The mask should collapse slightly and hold.
- Filters are consumable. Replace on schedule rather than waiting for a smell or a taste.
- Store the mask sealed. A mask left on a dusty bench is a dusty mask.
Safety notes
- Fit is everything. A mask that leaks at the nose delivers almost no protection, however good the filter.
- Beards and stubble break the faceseal. This is a fit problem, not a comfort problem.
- A mask is the last line of defence, not the first. Extract at the source and wet the work where you can.
