Safety

Peroxide-forming Solvents

All peroxide-forming solvents should have labels (available from the CBC Store) that indicate:

  • the date received
  • the date first opened
  • the dates tested (quarterly)

All peroxide-forming solvents must be checked for the presence of any peroxides prior to distillation or evaporation.

Peroxide test strips are available at the CBC Store. A copy of the colour indicator charts are available in each laboratory.

Solvents that have peroxide concentration values above 100ppm must be discarded.

If peroxide-forming solvents have unusual viscosity or crystal formation, do not move/open the container. Seek help from safety personnel immediately.
