Static electricity is often experienced, especially in the Japanese winter season. Many people are familiar with a crackling sound when taking off a sweater, for example, or have felt a shock when touching a metal doorknob.
Static electricity is the buildup of an electric charge in the human body or on the surface of an object. When an opportunity presents itself, it then gets discharged with a crackling or snapping sound. The TAIYO YUDEN Group takes measures to prevent static electricity in places where solvents are handled and other locations, observing the following points in order of priority.
Special Feature: Measures to Prevent Static Electricity Ignition
No Static Electricity Ignition!
In FY2010, a special audit was conducted at all business sites in the Group to verify if static electricity countermeasures were being carried out properly. When checked on the plant floor, a number of problems were found such as: earthing connections being interrupted and actually ineffective, dirt on the soles of shoes preventing the shoes from grounding the body, and resistance value measurement criteria not being set. Corrective action has been completed for all of these, and proper conditions are being maintained. At sites in tropical regions in particular, because of high humidity year round, a large number of employees had never experienced static electricity and did not know about it. It was thus necessary to teach basic knowledge about static electricity, and difficulties were experienced in training and getting employees to routinely carry out safety measures. We will continue to take measures to ensure that no static electricity ignition occurs.
