Chemical Substance Management

We are improving our chemical substance management system to ensure safety and prevent environmental pollution.

Chemical Substance Management

To protect employees from exposure to chemical substances and prevent health hazards, Chugai has established voluntary rules for chemical substance management and provides suitable work environments based on the results of risk assessments of the substances handled and the type of work. After protective equipment is selected, operations and procedures are determined. We also improved systems throughout the Chugai Group for risk assessment of chemical substances handled, in addition to restricted substances,*1 and are working to reduce the risk of occupational injuries from these substances.
By providing information in the form of safety data sheets (SDSs) and emergency contact cards (“yellow cards”), we also work to ensure safety at our contract manufacturers and other outside parties.
The handled amount of chemical substances in the April 2015-March 2016 period covered by the PRTR law*2 is as shown on the graph. While the amount of dichloromethane handled was fell, the handled amount of N,N-dimethylformamide and acetonitrile increased in association with increased production activity. As a result, the handled amount of substances covered by the PRTR law totaled 26.5 tons, an increase of 3 percent compared with the April 2014 – March 2015 period.

*1 In accordance with the Industrial Safety and Health Act revised in June 25, 2014, implementing risk assessments for chemical substances (640 items) became obligatory upon enactment of the revision on June 1, 2016
