Safety & Health

Safety Classification

The classification of soluble silicates in accordance with European standards for dangerous substances depends on their molar ratio n and solids concentration.

According to Regulation EC Nº 1272/2008 can be established:

Lumps and solutions with n > 3.2 y %MS > 40%: are not classified as dangerous.

Lumps and solutions with n > 2.6:

  • GHS07 Warning.
  • H315 Causes skin irritation.
  • H319 Causes serious eye irritation.

Lumps and solutions with 1.6 < n ≤ 2.6

  • GHS05 Danger.
  • H315 Causes skin irritation.
  • H318 Causes serious eye damage.

Solutions with n ≤ 1.6

  • GHS05 Danger.
  • H290 May be corrosive to metals.
  • H314 Causes severe skin burns and eye damage.
