Chemical Substances Control

With regard to chemical substances that we use and that are contained in component materials, we comply with the laws and regulations of Japan and of the regions to which we export. For chemical substances that are not regulated, we perform management based on voluntary standards to minimize impacts on people and the environment.

Chemical Substances Control Based on Voluntary Standards

In our internal regulations, we stipulate substances with the potential to pollute the environment, and mandate notification to the person responsible for environmental management when handling such substances. We assess the amount handled, the storage location, maximum storage capacity, and other matters for each substance, prepare SDSs*5 and emergency response equipment, and conduct periodic training to respond to unforeseen circumstances.
We are also examining alternatives to organic solvents and other hazardous chemical substances, along with ways to eliminate or reduce the hazards. 

*5SDS: Safety Data Sheet, which collects chemical substance name, manufacturer name, handling method, types of risks and hazards, physical characteristics, environmental impacts, safety measures, emergency response, emergency measures, and other information for chemical substances. Under the PRTR Law, manufacturers and other companies are required to aggregate amounts of chemical substance emissions and amounts of waste transfer, and to report these to the national government via local government bodies, with mandatory attachment of SDSs.

Specified Chemical Substances Control

Of chemical substances that we handle, we have submitted notifications for two substances that exceed standard amounts for substances specified by the PRTR*6 Law. In addition, at the Hachioji Plant we use and submit notifications for five chemical substances to be appropriately controlled according to the Tokyo Metropolitan Environmental Security Ordinance.

*6PRTR: Pollutant Release and Transfer Register. A system for the notification of releases and transfers of chemical substances.

Control of Chemical Substances Contained in Products

We conduct briefing sessions for suppliers to request strict control and reporting related to chemical substances contained in the parts we procure. So far, over 400 suppliers have participated. With the cooperation of suppliers, since fiscal year 2016 we have conducted cloud-based surveys on the RoHS Directive, REACH regulations, and other topics.

Since July 2017, we have managed six substances related to Metrology Company products in accordance with the RoHS Directive. Our export products for the EU region are 100% compliant with the directive. We are also examining the four types of phthalic acid that will be added to the RoHS Directive from July 2021. We have confirmed conformity for these substances and have begun shipments.

While Semiconductor Company products are exempt from the RoHS Directive as large-scale stationary industrial equipment, we are gradually adapting these to the directive as well. In fiscal year 2018, we established a RoHS Analysis Room to analyze chemical substances contained in procured parts.

Our products across the Company comply with the PFOA*7 regulations that were added to the POPs regulations in July 2020. We export 100% compliant products to areas where the regulations are enforced.

*7PFOA: Perfluorooctanoic acid.
