Silica dust will scar your lungs whether you cut granite worktops or pour concrete. The disease does not check your job title before it starts.

The HSA's silica awareness campaigns have done real work on Irish construction sites over the last decade. Awareness is up. Wet cutting is more common. RPE is at least being discussed. But the campaign framing, focused almost entirely on construction, has created a blind spot wide enough to drive a flatbed through. Thousands of workers in other industries are inhaling respirable crystalline silica every shift, with no wet suppression system in sight and no health surveillance in their contract.

Respirable crystalline silica, the particles small enough to reach deep into the lung tissue, sits in a long list of materials that have nothing to do with brick or block. Quartz is in ceramics. It is in vitreous china. It is in moulding sand. It is in glass. It is in the sandstone your stonemason is shaping for a hotel lobby. The physical process of cutting, grinding, drilling, or polishing releases those particles into the air. The lungs then do what lungs do: they trap them, and the silica stays there permanently.

The Industries Flying Under the Radar

Stone fabrication and monumental masonry. Granite, sandstone, and limestone all contain significant quartz. A stonemason cutting kerbing or a monumental mason shaping a headstone is in direct and sustained silica exposure. Many of these are small operations, one to three workers, no occupational health function, and safety management that amounts to a laminated poster near the sink. Engineered stone has now been banned in Ireland and the UK precisely because of catastrophic silicosis rates in fabricators, but natural stone still carries serious risk and receives far less attention.

Foundries and metal casting. Silica sand is the core material in sand casting moulds. Workers mixing, pouring, and breaking out castings are exposed during multiple stages of the process. Breakdown of used moulds generates dust loads that can be extremely high. Irish foundries are small in number but employ workers in close, sustained contact with silica-bearing sand for entire careers.

Ceramic and refractory manufacturing. Clay bodies, glazes, and refractory materials contain quartz and cristobalite. Workers in ceramic tile production, sanitaryware manufacturing, and refractory product lines are exposed during raw material handling, pressing, grinding, and fettling. The exposure is often dusty work in poorly ventilated factory spaces. The workforce tends to be older, long-tenure, and in some cases working in facilities where dust controls have not been updated in 20 years.

Road maintenance and quarrying. Milling machines chew up road surfaces that contain silica-bearing aggregate. Road workers operating or walking near milling equipment face real exposure risk during resurfacing works. Quarry workers crushing and processing stone face some of the highest ambient concentrations of any industry. The HSA runs quarry-specific campaigns, but uptake on dust monitoring and health surveillance in smaller quarry operations remains inconsistent.

Pottery and craft studios. This one catches people. Studio potters who mix their own clay bodies from dry materials, who grind their own glazes, who use silica as a kiln wash, are exposed without any employer structure in place. They are the employer. Many have no idea they are working with a substance that carries a mandatory occupational exposure limit under Irish law.

What the Law Already Says

The Safety, Health and Welfare at Work (Chemical Agents) Regulations apply to silica dust across all industries, not just construction. The occupational exposure limit for respirable crystalline silica in Ireland is 0.1 mg per cubic metre as an eight-hour time-weighted average. That limit applies in a foundry the same as on a building site. Employers are required to assess exposure, implement controls in hierarchy order, and provide health surveillance where exposure is likely.

Health surveillance matters here because silicosis develops over years, not weeks. By the time symptoms appear, meaningful lung capacity is already gone. Surveillance catches early changes before they become irreversible. In industries outside construction, most workers have never had a baseline lung function test.

The regulatory framework is not the problem. Enforcement reach and sector awareness are.

The Pattern That Keeps Repeating

Small businesses in stone, ceramics, and foundry work share a common profile. Owner-operator or family run. No safety officer. Generic risk assessments that were probably written by someone who never visited the site. Dust controls that exist on paper but not in practice. Workers who have been doing the job for 20 years and feel fine, which tells them nothing useful about what is happening inside their lung tissue right now.

The HSA cannot be everywhere at once. That is a fact of resource constraint, not failure. But the silica campaign material, the toolbox talks, the site posters, the enforcement visits, all skew heavily toward construction. A foundry manager in the midlands may never have had a conversation about respirable crystalline silica with anyone.

What Needs to Change

Trade associations in ceramics, stone, and foundry sectors need to take ownership of this. The information exists. The controls are well established: wet methods, local exhaust ventilation, enclosed cabs on plant equipment, RPE for residual exposure, and health surveillance. None of this is exotic. A small stonemason's yard can install a wet cutting bench for a few hundred euro and eliminate the majority of the exposure risk.

The conversation about why silica warnings fail to land applies just as much outside construction. Workers across all these industries do not see the dust as a live threat. It is in the air. It always has been. Nobody fell ill today. This normalisation is the actual killer, and it is just as present in a ceramic factory as on a demolition site.

The HSA should extend its surveillance and campaign focus beyond construction in any future silica push. The disease does not observe sector boundaries. Neither should the prevention effort.

Every industry that cuts, grinds, or shapes silica-bearing material has this problem. Most of them just have not been told yet.
