Violation

On December 18, 2023, Mitsuyama Co., Ltd. conducted work to sort debris such as wood chips contained in concrete residue during the operation of a belt conveyor. Despite the risk of workers' body parts being caught and injured, the company did not equip the conveyor with an emergency stop device that could be immediately activated in an emergency, nor did it take necessary measures to prevent hazards caused by machinery and equipment. The company and its representative director, Kazuo Mitsuyama, each received a summary order for a fine of 200,000 yen from the Yanai Summary Court for violating Article 20, Item 1 of the Industrial Safety and Health Act and Article 157, Paragraph 1 of the Industrial Safety and Health Regulations. The sentence was finalized on August 2, 2024. This is recognized as corresponding to Article 28, Paragraph 1, Item 3 of the Construction Business Act.
