We are aware that among the various potential environmental risks involved in Murata's activities, chemical contamination is of particular concern. The Murata Group works to prevent such risks by taking countermeasures, including facility preparation and employee training. We also promote initiatives to reduce other environmental risks, such as waste and related problems.
We are preparing facilities intended to eliminate any impact on the surrounding environment in order to minimize potential environmental risks of Murata's business activities, particularly in the event of accidents. With special consideration for the scale and period of impact, we have established the following four voluntary standards for storing and transporting chemical substances within plant facilities.
| 1. |
Prohibition against Underground Storage Tanks
In principle, storage tanks for fuels, organic solvents, acids, alkalis and waste liquids; and wastewater tanks for treating wastewater shall be located above ground. If it is unavoidable that a tank be placed underground due to legal requirements, it shall be a double-walled tank. |
| 2. |
Permeation Barrier Coating
Locations where fluids such as fuels, organic solvents, acids, and alkalis as well as waste oil are handled shall be provided with a bed made of a permeation barrier coating or stainless steel. |
| 3. |
Prohibition against Underground Piping
Pipes for transporting fluids such as fuels, organic solvents, acids and alkalis as well as waste liquids shall be located overhead. |
| 4. |
Emergency Containment Structure
Workplaces where liquids are received or where waste liquids are discharged to or from tank trucks or the like shall have a structure for immediately containing any leakage should an accident occur. |
Murata's plants and subsidiaries entrust the disposal of industrial wastes to licensed specialist companies. At fixed intervals we inspect their disposal sites in Japan and overseas, to ensure proper disposal.

To minimize environmental risks in the event of a natural disaster or serious accident, we regularly implement training for employees to deal with such emergencies.
Should a serious environmental accident or complaint arise, employees are mandated to immediately address it and report to the Head Office of Murata Manufacturing, so that we can share the reported information and implement horizontal countermeasures to prevent similar accidents from occurring at subsidiaries. In fiscal 2005, there were no significant accidents or complaints related to environmental issues.
