All factories have an ongoing commitment to environmental improvement activities in accordance with the Management System Standards of ISO14001. With respect to all environmental aspects, the company has established and strictly abides by its own voluntary standards that are more stringent than the national or regional regulation values. In accidents or emergencies liable to cause environmental pollution, individual factories and their each department have clearly defined procedures and priorities to prevent or mitigate pollution. Daily activities include regular emergency drills and training events to acquire and improve competence in accident and emergency defense procedures.
