Occupational Health and Safety


ASEH is committed to providing workers with a safe, healthy, and conducive work environment. To ensure the health and safety of employees, and prevent accidents at the workplace, we have formulated comprehensive procedures for managing occupational health and safety ("OHS"). The main focuses of ASEH's OHS Management include the OHS Management System and health promotion.

All ASEH facilities worldwide have established OHS management organizations, and formulated methods and procedures that follow ISO 45001/OHSAS 18001 standards, the RBA Code of Conduct and local regulations. In addition to setting up a system for regular reviews, the OHS management system contributes effectively to preventing accidents and achieving the goal of ‘zero accidents’. The OHS Committees at ASEH’s worldwide facilities are tasked to keep abreast of local regulatory updates and evaluate internal policies, emergency response and environmental safety procedures, so as to ensure compliance with applicable laws and regulations.


Occupational Injury Management

Occupational injury and incident reporting and investigation procedures are firmly established at all ASEH facilities. When an occupational injury incident occurs, standard operating procedures shall be followed and reported to local authorities in accordance with the management policy and local regulations, while injury incidents are reviewed regularly to improve preventive measures. Each subsidiary manages the statistical analysis of occupational injuries using the major indicators published by the Ministry of Labor and the Global Standards for Sustainability Reporting (GRI Standards) - Disabling Injury Frequency Rate (FR) and Disabling Injury Severity Rate (SR) are key measurements but the statistics do not include traffic accidents. There were 123 incidents of occupational injuries in 2021, amounting to 3,216 lost working days.


Establishing a Medical Mask Factory for Employee Health and Safety Protection

Since the onset of the Covid-19 outbreak in 2020, ASEH has proactively responded with robust measures to protect the health of its employees. All employees are required to wear medical masks before entering ASEH facilities. To ensure adequate access to masks, we have constructed a Class 100K cleanroom to produce medical grade masks that meet regulatory health standards. The cleanroom is equipped with particle measuring systems (PMS) to maintain a clean production environment. We also promoted sustainability by minimizing the use of packaging materials and automating the production line to increase our operational efficiency. For the safety of employees on the production floor, we have retrofitted our machines with a safety device developed and modified the dust collector to reduce noise and vibration. Our mask line began volume production in August 2020 after a medical device license was granted from the Ministry of Health and Welfare. Since then, we have been providing a variety of high quality masks, free of charge, to nearly 60,000 ASEH employees. As COVID-19 cases continue to spiked, we are ramping up our monthly production and distributing more masks so that employees could replace them more frequently.

Health Promotion

The healthy workplace development principles proposed by the World Health Organization (WHO) stipulate that a healthy workplace must account for the following aspects; "Workplace Physiological Health", "Workplace Psychosocial Health", "Personal Health Resources" and "Community Involvement". Moreover, it must strive for continuous improvement by implementing processes of integration, needs assessment, prioritization, planning, execution, evaluation, and improvement. ASEH provides our employees with various medical, health and psychological counseling services, formulates employee health management measures based on the concept of preventive healthcare, emergency infectious disease response procedures, emergency rescue procedures and maternal health. The company identified employees with high health risks and offered them health improvement plans as well as inviting them to participate in health improvement activities.

Contractor Operation Safety Management

ASEH facilities have established contractor management policies to ensure that safety protocols are observed when contractors work at our facilities and to achieve the target of zero contractor occupational injuries. Eight high-risk types of operations at ASEH’s facilities were identified which include work on pipelines, flammable sources, work inside confined spaces, live-line, crane operations, elevated operations, chemical filling and roof works, for which stricter SOPs were instituted. Additionally, ASEH will continue to request contractors conducting high-risk operations to meet the requirements specified in the ISO 45001 management systems.
