Management of Chemical Substances in Business Activities

Toshiba Group classifies the handling of chemical substances into the three categories of prohibition, reduction, and control, and manages each of them according to internal regulations. The relationship between the ranking of substances and management classifications, which underlies this initiative, is indicated in the chart below. Approximately 2,000 types of chemical substances are classified into three ranks (hazard level A, B, and C) based on the regulatory levels set by environmental legislation, data on carcinogenic properties, and other factors. Chemicals are classified into prohibition, reduction, or control by determining their respective risk upon combining the rank of the substance that shows the hazard level and their emission which mean the impact of exposure to the substance.
