Singapore entities following the accident, reviewed our material handling operations and intensified safety assessments. We continued to emphasise the importance of workplace safety across our businesses and our commitment to “Safety Before Profits”. People: We promote the professional and personal development of our employees.

This promotes a culture of continuous learning among our people as workplace needs and challenges, as well as industry expectations continue to evolve.
