Practice question · Sort into groups
Sort each practice by whether it is ACCEPTABLE or NOT in a studio containing silica dust.
Groups: Acceptable · Not acceptable
- Using a household vacuum without a suitable filter
- Relying on a loose paper mask instead of controls
- Local exhaust ventilation at the point of generation
- Wet-sanding a leather-hard surface
- Dry-sweeping the floor at the end of the day
- Mopping settled dust
Hints
- The rule is to stop dust becoming airborne, or capture it where it is made.
- Anything that re-suspends settled dust is unacceptable.
Show the answer
Acceptable: Wet-sanding a leather-hard surface, Mopping settled dust, Local exhaust ventilation at the point of generation
Not acceptable: Dry-sweeping the floor at the end of the day, Using a household vacuum without a suitable filter, Relying on a loose paper mask instead of controls
Why
Dry-sweeping is the standard error because it looks like cleaning. It re-suspends exactly the fraction that had settled, the fine particles that stay airborne longest and reach deepest, so it converts a tidy floor into an hour of exposure.
