Risk Management

TAIYO YUDEN Group implements risk assessment based on expected safety, health, and environmental impacts annually, and makes countermeasures to prevent occurrence of risks.
Fire/explosion, and spillage/contamination of chemical substances affect on not only corporate activities but stakeholders, thus we consider these risks are significant.

Appropriate Management of Chemical Substances

To ward off environment contamination with chemicals and adverse effects on human health, we have banned the use of forbidden substances, implemented a chemical management framework, and are working on reducing emission volumes.

Chemical Management Framework

The Taiyo Yuden Group has its own standards in place for chemical substance management, which define chemical substances that must not be used, must only be used in limited situations, and must be managed.

Target Chemicals

Prohibited substances Cadmium, compounds containing cadmium, mercury, compounds containing mercury, hexavalent chromium compounds, etc.
Substances to be restricted Lead in ceramic/glass frit and piezoelectric bodies, tetrabromobisphenol A (TBBPA), polycyclic aromatic hydrocarbons (PAHs), and so on.
Substances to be managed Toluene, REACH SVHC (substance of very high concern), xylene, etc.

PRTR Law Compliance

In order to reduce the risks that chemicals impose on the environment, the Taiyo Yuden Group reports to the government the amounts of chemicals released to the environment (air, water, and soil), and waste chemicals transported and recycled under the Japanese Law for Pollutant Release and Transfer Register (PRTR). The government publishes the records and a database of these quantities making them widely available to members of the general public.

PRTR Restricted Substances

Note: Target chemical substances and their incoming amount shown refer to substances for which their incoming amount exceeds 1 ton in compliance with the PRTR Law.
Emission: This refers to the total emission into the atmosphere, water, and soil.
Amount Transferred: This refers to the amount whose disposal is outsourced to an industrial waste contractor outside the business facility concerned.

Ozone-depleting Substances

We do not use ozone-depleting substances in our production processes. Although we use HCFC as a coolant in air conditioners and other equipment, we carry out appropriate collection and disposal.

Preparation for Emergency

Various types of regularly scheduled training are implemented to respond to sudden accidents, disasters, and other risks, with the objectives of early discovery, rapid response, prevention and mitigation. The Taiyo Yuden Group reconfirms appropriate procedures and strives for continuous improvement.

Firefighting Training

We conducted initial firefighting training assuming a nighttime fire. (October 2022)
We conducted fire extinguisher handling training using a powder fire extinguisher. (May 2022)
We conducted water hose handling training under the guidance of the fire department. (June 2022)

Emergency Training for Spillage of Chemical Substances

Tamamura Plant
We conducted shielding and collection training for drainage ditch assuming that a chemical substance leaked into the drainage ditch. (August 2022)
TAIYO YUDEN Mobile Technology
We conducted off-site leakage prevention training assuming that untreated wastewater leaked. (January 2023)
We conducted collection training assuming that a chemical substance leaked during transportation. (December 2022)

Evacuation and Medical Emergency Training

Takasaki Global Center
We conducted transportation training assuming that injuries occurred during a fire. (October 2022)
Yawatabara Plant /
We conducted evacuation training assuming that a fire. (November 2022)
Staff learned the measures to take if a person's airway becomes obstructed and cardiopulmonary resuscitation. (December 2022)

Removing Soil Contamination

We conducted a survey based on the Soil Contamination Countermeasures Act at the R&D Center and confirmed that the results were within the standard values. The Takasaki Global Center and Tamamura Plant conduct surveys based on the Soil Contamination Countermeasures Act and systematically implement countermeasures.

Environmental Accidents

No accidents that could affect the surrounding environment have occurred.

Measures for Prevention of Fire and Explosion

We have established our own voluntary standard on the three elements of combustion (combustibles, oxygen, and heat sources) as prevention measures for fire and explosion, and we implement measures and conduct management accordingly.
In addition, we conduct training on firefighting/evacuation every year in preparation for the breakout of a fire.
No fire or explosion has occurred.
