Risk Assessment and Management
To effectively prevent the occurrence of occupational harm, overall production plants have established OHS hazard identification and assessment mechanisms for risks and opportunities based on each site’s characteristics. These mechanisms form the basis for identifying and evaluating OHS hazards and risks arising from operating activities on employees, stakeholders, or the workplace, as well as identifying items for which risks should be managed and opportunities can be enhanced.
For example, each plant in Delta’s Taiwan region conducts hazard identification and risk assessment of all operating procedures on a regular or as-needed basis. Risk assessment updates are carried out for all plants at least once a year, and risks are quantified for all operations to ensure that all operational risks are effectively monitored. For risks that are classified based on the risk assessment level as unacceptable risks, the top three high-risk items in each department, OHS fines or requirements to make improvements by a deadline from the competent authority, and OHS incidents that occurred within the previous year, the best feasible control measure should be chosen based on the order of “Elimination, Substitution, Engineering Controls, Administrative Controls, and Personal Protective Equipment”. Furthermore, management plans or risk control measures shall be formulated, and they shall be regularly tracked and reviewed in order to effectively reduce risks from activities and operations in plants. All plants undergo annual risk assessments. Moreover, when employees discover potential OHS risks in their daily operations, they can also report the risks through internal channels in order to eliminate hazardous factors that may cause work-related injuries or ill health, thereby preventing incidents.
When employee discover that a dangerous situation is occurring during their work, they can immediately stop the operation and report the situation, and evacuate to a safe place. No punishment will be given for such actions. In addition, in terms of mechanical equipment procurement and process changes, procurement and the management of change are used to assess the safety of mechanical equipment and add safety and protective measures before procurement, in order to ensure the health and safety of personnel and plants. In 2024, the Taiwan and Mainland China regions worked with Cyntec to jointly develop and introduce an electronic system for applications and reviews for the management of change. The electronic operations allow for more convenient and timely operations as employees can apply for change reviews, which means the management of machinery and equipment could be more effectively accomplished at the source.
Occupational Health & Safety Internal Inspections
To ensure the safety of employees, OHS personnel conduct plant safety inspections on a regular and as-needed basis to oversee personnel operations and environmental safety. These safety inspections include electrical safety, fire safety, machinery/equipment/tool management, chemicals management, workplace, and safe operating procedures and protection. Deficiencies found in 2024 were mainly electrical safety (27%), workplace (22%), and machinery, equipment, and tools (21%). All deficiencies were corrected with guidance from the OHS personnel in the plants and the supervisory unit.
In the Mainland China region, in addition to inspections by OHS personnel, supervisors at all levels also conduct on-site audits on a monthly basis, in which they conduct walking inspections to obtain an understanding of the safety status at each plant’s operating environment, as well as plan and promote practical safety management measures. These audits demonstrate supervisors’ emphasis on health and safety management.
Management of Hazardous Chemical Substances and Workplace Monitoring
Chemical management at Delta is conducted via a source control method. Before a new chemical is introduced, the user must first submit a New Chemical Assessment, and OHS personnel must assist in assessing the chemical’s hazards and risks and provide suggestions. The user must choose chemicals with lower hazard levels in the design phase to replace more hazardous chemicals, ensure that optimal control measures are taken, and comply with laws and safety standards. All regions and plants comply with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which forms the basis for managing chemicals’ container labeling and safety datasheets at plants, thereby effectively communicating chemical hazard information.
In 2024, the Taiwan and Mainland China regions worked with Cyntec to jointly develop and introduce an electronic system for new chemical applications and reviews. The electronic operations allow for more convenient and timely operations by employees applying for change reviews, which meant the management of chemicals could be more effectively accomplished at the source.
In addition, to ensure oversight toward actual workplace and assess employees’ exposure to chemicals, as well as prevent work-related ill health, overall production plants conduct workplace environmental monitoring in accordance with local laws and regulations. Monitored items include chemical and physical factors, and the monitored items for chemical factors are mainly isopropyl alcohol, tin, methanol, and lead. The physical factors monitored mainly include noise, illuminance, and wind velocity. All monitoring results comply with local regulations and are publicly announced.
A small number of personnel are involved in ionizing operations at some Delta plants. We regularly provide special health examinations for these personnel and ensure that operators are qualified in accordance with local laws and regulations and comply with control requirements for operating sites.
