Chromate in cement

The calcium compounds in cement and mortar products irritate the skin and mucous membranes. Water-soluble chromate in cement may cause eczema on contact with the skin.

The use of cement and unset products containing cement with a content of water-soluble chromate of more than 2 mg per kg of dry cement is prohibited.

If means (iron sulphate) are used to reduce the chromate content in cement and products containing cement, the packaging must be labelled with clearly legible information on:

  • Content of water-soluble chromate.
  • Packaging date.
  • Conditions for storage.
  • Storage period.

Work site usage instructions must normally be prepared when cement is used.
