CSB Updates Recommendation Status – 11-09-23

Yesterday, the Chemical Safety Board updated the status from ‘Open’ to ‘Closed’ for of one of the recommendations from the Optima Belle investigation. The change in status of recommendation 2021-02-I-WV-R14 reflects the fact that the National Center for Biotechnology Information has updated the PubChem database entry for sodium dichloroisocyanurate (NaDCC) to reflect the hazards reported by the CSB.

This updated safety information is important because NaDCC is used as a water purification chemical as a substitute for sodium hypochlorite. Organizations that use or sell NaDCC (especially pool/spa vendors and support companies) need to review the revised safety information.
