Machine-translated summary — verify against original

Between July 4 and July 8, 2022, an safety audit was conducted on Yokohama Rapid Railway Co., Ltd. resulting in findings that required corrective actions. The audit revealed that some personnel certifications issued after January 11, 2022, incorrectly used the certification validity period based on the date of mental function tests, despite the knowledge and skills verification being older. Additionally, some staff were allowed to perform tasks related to train or vehicle operation without prior confirmation of necessary aptitude, knowledge, and skills, contrary to internal standards. The company was instructed to establish a proper system for verifying personnel qualifications in accordance with the operational standards for train handling. The company was also asked to investigate the root causes of these issues and prevent recurrence, with a report due by October 17, 2022.
