Concrete & Silica Dust Collection
Engineered dust control for cutting, grinding, crushing, and surface prep — designed to meet OSHA’s crystalline silica standard without relying on respirators.
Respirable crystalline silica is one of the most regulated airborne hazards in manufacturing and construction. Particles generated from cutting, grinding, drilling, or crushing concrete, stone, masonry, and engineered quartz are small enough to penetrate deep into lung tissue — and the damage is irreversible. That’s why OSHA’s silica standard (29 CFR 1926.1153 for construction, 1910.1053 for general industry) sets the Permissible Exposure Limit at just 50 μg/m³ over an eight-hour shift.
The good news: OSHA’s Table 1 provides a straightforward path to compliance. If you use the specified engineering controls for each task — the right dust collector, vacuum, wet method, or ventilated enclosure — you’re compliant without air monitoring or respirators. We design and install systems that meet Table 1 requirements and provide the documentation to prove it during inspections.
In the Southwest, silica dust is everywhere — not just in concrete operations. Desert ambient dust contains high concentrations of crystalline silica, which means facilities already start with elevated background levels before any process-generated dust enters the equation. We factor this into every system design.
Every system we install is backed by our pass-or-free compliance guarantee. If it doesn’t pass OSHA inspection due to our design or installation, we fix it at no cost.
Understanding OSHA’s Silica Rule
OSHA’s crystalline silica standard applies to any operation that generates respirable silica dust. There are two versions — 1926.1153 for construction and 1910.1053 for general industry — but both set the same 50 μg/m³ PEL. Here’s how compliance works:
Table 1 (Simplest Path)
Match the specified engineering control to the task. If you follow Table 1 exactly — using the correct dust collector, vacuum, or wet method for each tool — no air monitoring or respirators are required. This is how most facilities achieve compliance.
Alternative Exposure Control
If you can’t follow Table 1 exactly, you can still comply by demonstrating exposures are below 50 μg/m³ through air monitoring. This requires initial monitoring, periodic reassessment, and a written exposure control plan.
Documentation Requirements
Both paths require a written exposure control plan, designated competent person, housekeeping protocols, employee training records, and medical surveillance for workers exposed above the action level (25 μg/m³). We provide all documentation templates.
Table 1 Compliant Equipment
HEPA Vacuums & Shrouds
99.97% filtration at 0.3 μm paired with OSHA-approved tool shrouds for handheld grinders, drills, saws, and jackhammers. The most common Table 1 solution for individual tools.
Downdraft Tables
Ventilated work surfaces that pull silica dust downward and away from the breathing zone during grinding, polishing, and surface prep on smaller workpieces.
Central Baghouse & Cartridge Systems
High-capacity dust collection for batch plants, crushing operations, screening, conveyor transfer points, and multi-station grinding facilities.
Wet Collectors
Water-based dust suppression for cutting, demolition, and crushing where dry collection isn’t practical. Eliminates secondary dust exposure during filter changes.
Source Capture Hoods & Arms
Positioned extraction at fixed workstations for bench grinding, tuckpointing, and mortar removal. Captures dust before it reaches the worker’s breathing zone.
Exposure Control Plans
Written documentation packages including task-specific controls, competent person designation, housekeeping protocols, training records, and medical surveillance guidance.
Common Silica Dust Applications
Concrete Cutting & Coring
Wall saws, flat saws, core drills, wire saws. Table 1 requires either wet methods or vacuum/shroud systems.
Surface Prep & Grinding
Floor grinders, polishers, scarifiers, coating removal. Requires shroud with vacuum or ventilated enclosure.
Demolition & Crushing
Jackhammers, crushers, recyclers. Wet suppression is most practical for large-scale demolition operations.
Masonry & Tuckpointing
Mortar raking, brick cutting, stone fabrication. Among the highest silica exposure tasks — engineering controls are essential.
Batch Plants & Ready-Mix
Sand handling, cement loading, aggregate transfer. Central collection systems with bin vents and conveyor hoods.
Countertop Fabrication
Engineered quartz (93%+ silica), granite, and stone. Cutting, shaping, and polishing with wet or vacuum systems.
Foundry & Casting
Sand mold handling, shakeout, grinding of castings. Silica content in foundry sand is typically 95%+.
Landscaping & Hardscaping
Cutting pavers, retaining wall blocks, and decorative stone. Often overlooked but fully covered by the silica standard.
Silica in the Southwest
The Southwest presents unique silica challenges that don’t exist in most of the country. Desert soils throughout Arizona, Nevada, New Mexico, and parts of California and Utah contain naturally high concentrations of crystalline silica. Wind events like Phoenix haboobs and southern New Mexico dust storms drive fine silica particulate into facilities year-round.
This means your baseline ambient silica levels may already be elevated before any process-generated dust enters the picture. A system sized for the process alone might not keep you below the 50 μg/m³ PEL once ambient loading is factored in. We account for this in every Southwest design.
California facilities face additional requirements under SCAQMD Rule 1466, which regulates silica emissions from handling and processing operations — a layer on top of federal OSHA. We navigate both.
