Vacuums for silica and construction dust.

Respirable crystalline silica is one of the most serious dust hazards on site. Here is how the right M- or H-class vacuum helps you control it — and meet COSHH.

The Risk

Respirable crystalline silica

Cutting, grinding, drilling or polishing concrete, stone, brick and many composites releases respirable crystalline silica (RCS) — fine enough to reach deep into the lungs and a recognised cause of silicosis and lung cancer. HSE sets a workplace exposure limit for RCS of 0.1 mg/m³ over an eight-hour day, and controlling exposure is a COSHH duty.

The most effective control is to capture the dust at the point it is created — on-tool extraction (LEV) paired with a vacuum rated for the dust — rather than letting it become airborne and sweeping up afterwards.

Specification

Why an M-class dust extractor is the minimum for silica

Industrial vacuum filtration is graded by class under BS EN 60335-2-69. For respirable crystalline silica, an M-class dust extractor (Class M filtration) is the practical minimum; for the highest-hazard work, Class H (HEPA H13/H14) gives the greatest protection. Just as important is how the dust leaves the machine: contained, low-exposure disposal — such as a Longopac continuous liner — keeps operators away from the collected dust.

A Starting Point

Matching the vacuum to the task.

A rough guide — the right specification still depends on your task, volume and how the dust is generated.
