ABC has a set of "Contractor Safety and Health Management Policy" in place to ensure the safety of contractors' work activities while at the same time prevent occupational hazard and pollution. Contractors are informed of safety and health awareness issues, notified of potential hazards, and instructed to comply with Occupational Safety and Health Act, environmental protection laws, and internal policies on environmental protection, safety, and health before performing work activities on plant premises. Contractors are required to conduct thorough inspections of the work site and work equipment on a daily basis over the course of contracted work. Any high-risk work activities have to be applied three days in advance. Coordination meetings are held from time to time to communicate with contractors on government laws, updates of plant premises, audit outcomes, improvement suggestions, and work-related requirements, and thereby prevent accidents and personnel injury. The total number of hours worked by the contractor in 2022 was 347.5, and there were no incidents of permanent injuries, partial permanent injuries, or temporary injuries during their operations.
