ST Engineering Sustainability Report 2021

SOCIAL As part of its 2021 workplan, the Workplace Safety & Health (WSH) Committee reviewed and aligned our safety performance indicators. This included adopting ISO 45001 Occupational Health and Safety Management Systems revising our WSH indicators, carrying out a group-wide WSH promotion and campaign, enhancing WSH digital platforms (e.g. injury reporting, hazard reporting) and emphasising mental wellbeing at our workplaces. In Singapore, the Group partnered the Workplace Safety and Health Council (WSHC) to offer health and safety workshops including health screening and coaching, infectious disease control and mental health. To ensure we remain compliant with relevant statutory and regulatory requirements, the Group continues to use control self-assessment and audit processes as part of our enterprise risk management initiatives. SAFETY PERFORMANCE The Accident Frequency Rate (AFR) and Accident Severity Rate (ASR) in 2021 were 1.1 and 22.0 respectively. The AFR of our global operations increased from 0.8 to 1.1, and the corresponding ASR increased from 17.2 to 22.0. One of the key factors that contributed to our slip in performance was due to human error in complying with safety procedures. We regard safety and wellness as paramount to our everyday work. Above and beyond legal requirements, we do our best to prevent occupational injuries and illnesses. We also strive to promote a healthy and balanced lifestyle among our staff. → → Reviewed and aligned our safety performance indicators → Safeguarded staff wellness through the engagement of the Workplace Safety and Health Council for mental health and mental wellness WHAT WE ACHIEVED IN 2021 This is likely attributed to prolonged periods away from the workplace during the pandemic. In 2021, the two most frequent causes of injuries were cuts/stabbed by objects and being struck by objects. They accounted for 28% of all cases. Key mitigating measures are being adopted through continuous WSH education, assessments and surveillance activities within the group. They include cross sharing of best practices with our global operations, reviewing safe work procedures, conducting risk assessment on safe material and mechanical handling and stepping up enforcement on the use of specific personal protective equipment, tools and machinery safety as well as Lockout-Tagout. There was a decrease in falls from height incidents from 21% to 12%, the most frequent cause of injury in 2020. This can be attributed to our effective fall prevention programme which focuses on the following approaches such as intensive analysis of statistics; workforce direct engagement; series of comprehensive inspections; monitoring programme effectiveness; communication and feedback. We continue to advocate the importance of safe work procedures to our employees via awareness briefings, site inspections and other safety initiatives, to constantly remind employees to take care of their safety and that of their co-workers. → OCCUPATIONAL HEALTH PERFORMANCE INDICATORS* * Singapore operations Workplace Safety & Health activities organised 112 At-risk staff attended respiratory protection training 100% New occupational diseases cases (excluding noise induced deafness cases) 0 At-risk staff attended an audiometric examination 100% New advanced noise-induced deafness cases 0 TOTAL WORKPLACE SAFETY & HEALTH 35 ST ENGINEERING SUSTAINABILITY REPORT 2021 OVERVIEW OUR SUSTAINABILITY APPROACH ENVIRONMENTAL SOCIAL GOVERNANCE AWARDS INDEX
