Violation

On February 21, 2020, during demolition work in Osaka's Yodogawa Ward, Ikezawa Heavy Machinery did not appoint a steel structure work supervisor who had completed the required skills training as mandated by law, while dismantling steel structures over 5 meters high. During cutting work using a gas torch, sparks ignited building materials, causing a fire that resulted in a worker being burned and dying two months later. The company was found to have violated Article 14 of the Industrial Safety and Health Act, Enforcement Order Article 6, and Safety Regulations Article 517-4. A summary fine of 200,000 yen was imposed by the Osaka Summary Court on June 18, 2021, and this order was finalized. The incident is recognized as a violation under Article 28, Paragraph 1, Item 3 of the Construction Business Act. The prefectural authority, Nara Prefecture, issued a directive on September 15, 2021, requiring the company to take measures such as informing all staff of the violations, ensuring compliance with relevant laws through training, and strengthening safety management systems at construction sites. The source of the report was the Osaka Labor Bureau.
