Key Hazards
- Respirable silica dust exposure from concrete, brick, block, stone, or mortar
- Dust escaping from damaged hoses, seals, filters, or collection containers
- Workers using vacuums not rated for silica dust control
- Improper filter cleaning or dust disposal
- Trip hazards from hoses and cords
- False confidence when vacuum systems are poorly maintained or overloaded
2–3 Minute Talk Script
Silica vacuums are used to help control dust from concrete, masonry, stone, brick, block, mortar, and similar materials. They only work when the vacuum, filter, hose, and collection system are maintained.
Workers should verify that the vacuum is appropriate for silica dust control and the task being performed.
The vacuum should be inspected before use. Hoses, seals, filters, collection bags, dust containers, cords, plugs, switches, and tool connections should be checked.
Damaged hoses, loose seals, missing filters, full containers, or poor tool connections can allow dust to escape into the breathing zone.
Filters should be cleaned or replaced according to manufacturer instructions. Improper filter handling can release dust and expose workers.
Dust containers and bags should be emptied or changed carefully using the required procedure and PPE.
Hoses and cords should be routed to prevent trips and to avoid damage from sharp edges, traffic, equipment, or pinch points.
Safe silica vacuum use depends on the right equipment, inspection, good connections, proper filter maintenance, careful dust disposal, and respiratory protection when required.
Safety Reminders
- Use a vacuum suitable for silica dust control.
- Inspect hoses, filters, seals, and collection containers.
- Do not use vacuums with missing or damaged filters.
- Keep tool connections tight.
- Empty dust containers using the required procedure.
- Route hoses and cords safely.
- Use respiratory protection when required.
Ask the Crew
- Is this vacuum approved for silica dust control?
- Are hoses, filters, and seals in good condition?
- Is the dust container full or leaking?
- How will dust be emptied without exposure?
- Is respiratory protection required for this task?
