From awareness campaigns and hazard identification to emergency drills and skills competitions, each company translated safety concepts into concrete actions, cascading them to every employee and fostering a strong culture of full participation in safeguarding workplace safety. Work Safety Month serves not only as a comprehensive review of annual safety performance, but also as an important vehicle for strengthening the Company’s safety culture. Through these initiatives, employees’ safety awareness and emergency response capabilities were significantly enhanced, with hazard identification evolving from a “passive response” to “proactive detection”, and safety management transitioning from “activity-driven” to a more “systematic and sustained” approach. Leveraging this opportunity, The United Laboratories will continue to reinforce the foundations of work safety, ensuring that safety remains a cornerstone of its high-quality development.
