UL is advancing Workplace Health & Safety to help companies safeguard and enhance the well-being of their employees. We are pioneering the use of leading indicators, enabling a shift in focus to a more proactive prevention of illness and injury. We integrated health and safety management software to provide companies with greater transparency so they can more effectively detect and mitigate emerging risks. We employ a unique approach to help organizations build a health and safety culture in which employees go beyond compliance to actively engage in their own safety and that of their colleagues. We are innovating safety analytics to better understand and address the underlying causes of and contributing factors to workplace incidents. And we are developing new learning tools to change how managers and workers think and behave, in order to create healthier, safer workplaces.
