Chemical Substances Management

In regard to chemical substances we use and those contained in parts, we are committed to minimizing impact on the environment and people by not only observing laws and regulations in Japan and in export destinations but also managing non-regulated chemical substances based on voluntary standards.

Chemical Substances Management Based on Voluntary Standards

We apply internal company regulations which specify substances with the potential to pollute the environment. When these substances are used, the responsible person for environmental management must be notified. The amount of each substance used, the storage location, and the maximum storage amount are identified. SDS* and emergency tools are made available and regular contingency drills are conducted. Also, we are examining the replacement of harmful chemical substances (organic solvent, etc.) with harmless or less harmful substances.

SDS*SDS stands for Safety Data Sheet. Information on the name of the chemical substance, the manufacturer, handling methods, the nature of the hazard and type of toxicity, physical properties, impact on the environment, safety measures, emergency measures, and actions in the event of an emergency are recorded on this sheet for each chemical substance. According to the PRTR Law, manufacturers are supposed to compile the amount of emissions of chemical substances and the amount of transferred wastes and submit a report to the national government via local government. It is mandatory to attach SDS to the report.

Specified Chemical Substances Management

We have submitted notification for two substances whose amount of use exceeds the standard for the substances specified by the PRTR Law. With regard to the chemical substances requiring appropriate management stipulated in the Environmental Ordinance for Ensuring Health and Safety of Residents in Tokyo Metropolis, five of them are used in Hachioji Plant and we have submitted notification for them.

Control of Chemical Substances Contained in Products

We hold briefing sessions to request suppliers to strictly control and report chemical substances contained in procured materials. So far, more than 400 suppliers have attended the session.
Since fiscal 2016, we have been conducting an investigation on the RoHS Directive, the REACH Regulations, etc. using a cloud system.
Products of Metrology Company comply with the RoHS Directive from July 2017, and all the products exported to the EU are compliant.
Although products of Semiconductor Company are outside the scope of RoHS application, because they are large-scale installation-type industrial equipment, we are gradually taking measures to make them compliant.
In fiscal 2018, RoHS analysis laboratory, which is equipped with instruments for analysis of chemical substances contained in products, was installed to create an environment conducive for analysis.
