Under Cheng'an's guidance, the company's safety management system has gradually improved. Through daily safety education and training for employees, the safety system has become deeply rooted, and employees have gained knowledge on safe electrical usage, the role of safety corridors, and the handling of general fire emergencies, among others. Since the outsourcing, the company has reduced safety errors in production and prevented any safety accidents.
