To effectively prevent the occurrence of occupational harm, Delta has established occupational health and safety hazard identification and assessment procedures for risks and opportunities. It identifies and evaluates occupational health and safety hazards and risks arising from operating activities on employees, stakeholders, or the workplace, and identifies items for which risks should be managed and opportunities can be enhanced. In terms of the procurement of new equipment and process upgrades, we manage changes, implement pre-purchase safety evaluations, and increase safety measures for mechanical equipment. We also select low-hazard chemicals to replace high-hazard chemicals and adopt source control measures to ensure personnel and plant safety and health. For unacceptable risk control methods, Delta determines the best feasible control measures based on the order of elimination, replacement, engineering control, operation control, and personal protective equipment. It then uses them as the basis for occupational health and safety management objectives, operation control, emergency response measures, or training control measures to effectively reduce the risks of activities and operations in the plants.
Occupational Health & Safety Internal Inspections
The plants shall conduct automatic inspections and self-inspections under government regulations and Delta's operation standards to ensure the safety of employees and plants. Occupational health and safety management department personnel shall carry out routine occupational safety assessments and inspections. They must also perform sampling inspections on contractors' operational safety. Plants in each region shall promote interindustry health and safety inspection activities. Inspectors include safety and health management department employees of other plants, factory occupational health and safety management personnel, and departmental occupational health and safety promotion employees. Through the observational learning of cross-industry inter-inspector activities, factory personnel occupational health and safety management exchanges and interaction were improved as were manufacturing plant audits. Certain main production plants shall include inspection results in the occupational health and safety evaluation activity. The units with the most improvement shall receive commendations and bonuses as well as rewards for the implementation personnel to encourage improvements in how employees practice occupational health and safety management in their work. To effectively track the improvement status of occupational health and safety inspection deficiencies, electronic forms were issued across the board to address inspection deficiencies in 2023, which significantly improved the efficiency of improvements for deficiencies.
Management of Hazardous Chemical Substances and Workplace Monitoring
Delta's chemical management includes the following key steps: new chemical assessment, chemical control banding, chemical inventory, management of procurement and change, and site management. First of all, newly purchased chemicals or a change of the chemicals used in manufacturing processes must abide by regulations for the New Chemical Assessment of the plant and a review of new chemicals must be conducted to ensure that they comply with relevant laws and regulations and safety standards. The potential hazards and risks must be evaluated and such chemicals can only be used with approval from relevant units.
The chemicals used by Delta in Taiwan are managed with chemical control banding and require appropriate labeling, storage, and handling based on their hazards and risk levels. Each plant regularly appoints monitoring institutions approved by the competent authority to implement workplace monitoring pursuant to the characteristics of chemical hazards and local regulatory requirements to implement workplace monitoring to control the dispersion of hazardous factors in the workplace. They also take hazard control and prevention measures based on the monitoring results to prevent the occurrence of work-related ill health.
All plants implement environment monitoring in accordance with local regulations for both chemical and physical factors. According to the statistics, the main chemical factors were isopropanol, carbon dioxide, tin, and lead. The main physical factors were noise, illuminance, and wind speed. Additionally, few workers in certain plants engage in radiation operations. We work to prevent employee workplace exposure to hazardous elements and harm to their health according to local statutory regulations. As such, operators that handle hazardous materials undergo special health checks and the results of the checks are used for tiered management.
We have also established a complete list of chemicals to ensure that all chemical information is effectively recorded and tracked. In terms of management of procurement and change, we strictly control the adoption and use of chemicals, review and control any changes, and ensure that the procurement/change procedures of all chemicals comply with local legal requirements and company standards.
Finally, to ensure that chemicals comply with safety regulations during use, units using chemicals shall regularly or periodically conduct inspections on container labeling, protective equipment effectiveness, and other operations to ensure the implementation of the Company's chemical management measures, provide a safe environment for employees for the use of chemicals, and ensure the safety and health of employees.
