The all-island silica campaign landed hard on concrete-cutting crews and groundworkers. Good. They needed it. But the campaign drew a tight circle around one industry, and outside that circle, workers in equally dusty trades are still treating silica like someone else's problem.
It is not someone else's problem. Respirable crystalline silica does not care what sector you work in. Inhale enough of it over enough years and your lungs scar. Silicosis has no treatment. It does not reverse. And the industries quietly generating the same exposures as a busy construction site are largely flying under the radar of both regulators and the workers themselves.
What Makes Silica Dangerous Regardless of Industry
Silica is a mineral found in stone, sand, brick, mortar, and concrete. When any of these materials get cut, ground, drilled, or broken, the dust released can contain particles small enough to pass deep into lung tissue. That is respirable crystalline silica. The particles you cannot see are the ones doing the damage.
The occupational exposure limit in Ireland is 0.1 milligrams per cubic metre of air, averaged over an eight-hour shift. That sounds like a technical abstraction until you realise that a single angle grinder cutting sandstone in an enclosed space can push concentrations ten times that high within minutes. Workers who underestimate this risk often do so because the consequences arrive twenty years late, long after the exposure that caused them.
Stonemasons: High Exposure, Low Awareness
Traditional stonemasons working with granite, limestone, and sandstone are among the highest-exposure trades in Ireland. They are also among the least scrutinised.
A mason dressing a granite kerb by hand is generating a fine quartz dust. Granite contains roughly 25 to 30 percent crystalline silica by composition. Sandstone can run higher. Limestone is lower risk but not zero. Work outdoors with a breeze and the exposure may stay manageable. Work in a yard, a workshop, or a covered area and the dust accumulates fast.
The problem is that stonemasons, particularly those running small operations or working as sole traders, are unlikely to have had a site safety officer walk through their workspace with a dust monitor. The all-island campaign messaging reached main contractors and their subcontractors. It did not reach the one-man yard in rural Roscommon doing repair work on a local estate wall.
Demolition: Legacy Dust With No Warning Label
Demolition work was always going to generate silica dust. Breaking concrete, raking out mortar joints, crushing masonry: all of it releases respirable particles. What makes demolition particularly hazardous is that the materials being broken are often old, untested, and from an era with no safety data sheets.
A concrete structure from the 1960s contains silica. So does the brick infill around it. The mortar holding both together is loaded with it. Demolition workers swinging a hammer or running a breaker through a wall are generating clouds of mixed dust, some of which they have never formally assessed.
There is also the compounding problem. Asbestos in older Irish buildings means demolition teams are sometimes trained to look for one hazard and miss the other entirely. A building can contain both asbestos and silica-bearing masonry. Controlling one exposure pathway while ignoring the other is not a control measure, it is a gap dressed up as one.
Heritage Restoration: The Sector That Gets Left Out
Heritage and conservation work sits in an awkward position. It is skilled, specialist, and often publicly funded. It also involves prolonged, close-contact work with exactly the kinds of high-silica materials that drive the worst exposure profiles.
Repointing a Georgian terrace means working with lime mortar and stone, raking out old joints with an angle grinder or an oscillating tool, hours at a time, often indoors or in sheltered courtyards with minimal airflow. Restoring carved limestone or sandstone features on a church or a courthouse means grinding and shaping material that can contain 70 percent or more crystalline silica.
Workers on these projects are often highly skilled in their craft. They are not always equally well-informed about silica dust exposure. Heritage contractors tend to be smaller operators, working under planning and conservation constraints that already create pressure on method and pace. Adding respiratory controls to that environment requires active management, not a laminated poster on the site gate.
The irony is that heritage restoration is often presented as careful, considered work. And it is. But careful does not automatically mean safe from an inhalation standpoint.
What Good Control Actually Looks Like Across These Sectors
The hierarchy of control is the same regardless of whether you are cutting sandstone in a mason's yard or grinding mortar joints on a listed building.
Eliminate or substitute where you can. Hand tools instead of power tools generate less airborne dust. Wet cutting instead of dry cutting suppresses dust at the point of generation. These are not complex interventions. They are decisions made before the work starts.
Local exhaust ventilation matters in enclosed spaces. An angle grinder fitted with an extraction shroud and connected to an H-class vacuum removes dust at source. It costs money. It costs less than the legal, medical, and human consequences of getting it wrong.
Respiratory protective equipment is not a primary control, but it is necessary when engineering controls cannot reduce exposure below the limit. An FFP3 disposable or a half-mask with P3 filters. Not an FFP1 or FFP2. Not a paper dust mask from a hardware shop. The right equipment, worn correctly, for the full duration of the task.
Health surveillance for workers in these trades should mean periodic lung function testing, not a one-off medical when someone joins the company and nothing after that.
Why the Campaign Messaging Needs to Travel Further
The all-island silica campaign is welcome and overdue. But campaigns that reach the large main contractors first and the small specialist operators last are structurally limited. The worker cutting stone in a three-person outfit has no health and safety manager. Nobody is doing a toolbox talk before the Monday morning start.
Sector-specific outreach matters here. Stonemason guilds, conservation contractor networks, demolition associations, these are the channels that reach the people currently outside the campaign's line of sight.
Silica dust exposure is the same hazard whether it comes from a new housing development or a 200-year-old courthouse. The disease is identical. The prevention is identical. The only thing that varies is how long certain workers have been allowed to assume the risk belongs to someone else.
That assumption has already cost lives. Time to retire it.
