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 “Management System” and “Healthy Workplace”.

ASEH is committed to strict compliance with local regulations and international standards such as ISO 45001 Occupational Health and Safety Management System and the RBA Code of Conduct. To further improve the management standards of our health and safety performance, ASEH’s subsidiaries have established site management organizations, management policies and procedures, and regular internal audit processes. ASEH employs the PDCA model as an approach to prevent all incidents and achieve the management goal of “zero accident.”

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 127 incidents of occupational injuries in 2022.


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. Our production line is fully automated and uses less packaging materials allowing us to be more efficient and sustainable. For the safety of employees on the production floor, we have retrofitted our machines with a safety device and modified the dust collector to reduce noise and vibration. Our mask line was granted a medical device license from the Ministry of Health and Welfare. Since the beginning of mass production in 2020, we have been providing a variety of high-quality masks to nearly 60,000 ASEH employees, and will continue to produce enough free masks for the needs of every employee.

In addition to producing medical masks inhouse, we have also made an investment in Ainos Inc., a manufacturer of rapid COVID-19 detection kits. In our continued fight against Covid-19 and the protection of our employees and their families, ASEH has procured Ainos rapid detection kits to be distributed free of charge to employees.

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.
