As of 2026, there is no new regulation specifically targeting dust control on construction sites. However, several important laws remain fully in force — especially those related to respirable crystalline silica, which has been officially classified as a carcinogenic agent in Spain since 2020. At Almuco, we see the consequences every week in the workshop: saturated filters, under‑powered vacuums and tools that simply aren’t designed for the type of dust they generate.
In addition, organizations such as INSST, the Construction Labor Foundation and manufacturers such as Hilti are updating their guides and recommendations to reduce exposure to crystalline silica dust, classified as carcinogenic since 2020.
This article summarises the current legal framework and the most relevant technical recommendations for working safely with porcelain, concrete, brick and other high‑dust materials.
1. Crystalline silica is officially classified as a carcinogenic agent
Since December 2020, respirable crystalline silica has been included in Spain’s list of carcinogenic substances.
📌 Oficial Regulations: Royal Decree 1154/2020, which amends RD 665/1997 on the protection of workers from carcinogenic agents
This classification creates real obligations for companies and self‑employed professionals, including:
Risk assessment
Reduction of exposure at the source
Use of appropriate dust extraction
Training and preventive measures
2. What regulations actually apply to dust on construction sites?
✔ RD 665/1997 – Protection against carcinogens agent
✔ Occupational Risk Prevention Law (LPRL)
It requires reducing exposure to dust at source.
✔ INSST technical guidelines
The Spanish National Institute for Safety and Health at Work publishes guidance on chemical risks and dust control. (portal oficial)
✔ Sector‑specific guides
Manufacturers and organisations such as Hilti or the Construction Labour Foundation publish practical guides on dust control and safe work practices. Dust on Site Guide(FLC)
3. What do technical bodies recommend in 2026?
Even without new legislation, several recommendations have become standard practice:
✔ Class M vacuums as the professional baseline
For porcelain, concrete, brick and general construction work.
✔ HEPA filters for very fine or hazardous dust
Especially in indoor environments.
✔ Dust reduction at the source
Using tools compatible with dust extraction.
✔ Increased attention to indoor works
More inspections in renovations and small‑scale construction.
4. What does this mean for professionals?
In short:
There is no “new 2026 regulation”, but existing laws already impose strict obligations..
Crystalline silica is carcinogenic → proper dust extraction is mandatory
Class M is the minimum recommended for most construction tasks
Inspections increasingly focus on dust control, filter condition and vacuum saturation.
Conclusion
Dust on construction sites remains one of the most significant health and safety risks in the industry. Even without new laws this year, current regulations already require adequate extraction, correct filtration and dust reduction at the source.
At Almuco, we see the same issues every week: vacuums that can’t cope, filters that aren’t suitable and tools working under conditions they were never designed for. If you’re unsure which vacuum you need, we can help you choose the right one.
