The European Chemicals Agency (ECHA) is planning to tighten regulations on inorganic silicon compounds, particularly Silicon Dioxide (SiO₂) and crystalline silica, due to their health risks. These proposed regulations could impact industries like construction and cosmetics.

In a report released in September 2024, ECHA highlights the health risks associated with various forms of silicon compounds and the need for stricter regulatory measures across Europe. Common silicon compounds such as Silicon Dioxide (SiO₂), Silicon Carbide (SiC), and Trichlorosilane (SiHCl₃) are essential in many industries but pose significant risks to human health and the environment.

Risks Identified in the Report

ECHA’s report identifies both crystalline and amorphous silicon compounds as hazardous. Crystalline silica can cause silicosis and lung cancer when inhaled, particularly in industries like construction and stone cutting. Meanwhile, amorphous silicon compounds, such as synthetic amorphous silica (SAS), pose long-term risks through inhalation exposure, though they are not classified as carcinogens.

Regulatory Actions Proposed by ECHA

ECHA is recommending new occupational exposure limits (OELs) for respirable crystalline silica (RCS) and tighter restrictions on industries that generate significant amounts of crystalline silica dust, such as quarrying and ceramics. The agency is also considering additional regulations for industries using synthetic amorphous silica (SAS) in adhesives, paints, and cosmetics.

These proposed regulations could have far-reaching implications for industries like construction, manufacturing, and technology. Businesses may need to adopt new dust suppression technologies and protective measures to comply with the updated regulations.
