28 April is celebrated every year as the International Day for Safety and Health at Work. In 2003, the International Labour Organization (ILO), began to observe World Day in order to stress the prevention of accidents and diseases at work. Prevention of occupational accidents and diseases The annual World Day for Safety and Health at Work on 28 April promotes the prevention of occupational accidents and diseases globally. It is an awareness-raising campaign intended to focus international attention on the magnitude of the problem and on how promoting and creating a safety and health culture can help reduce the number of work-related deaths and injuries. Each of us is responsible for stopping deaths and injuries on the job. As governments we are responsible for providing the infrastructure (laws and services) necessary to ensure that workers remain employable and that enterprises flourish; this includes the development of a national policy and programme and a system of inspection to enforce compliance with occupational safety and health legislation and policy. As employers we are responsible for ensuring that the working environment is safe and healthy. As workers we are responsible to work safely and to protect ourselves and not to endanger others, to know our rights and to participate in the implementation of preventive measures. Emerging risks at work New and emerging occupational risks may be caused by technical innovation or by social or organizational change, such as: New technologies and production processes, e.g. nanotechnology, biotechnology New working conditions, e.g. higher workloads, work intensification from downsizing, poor conditions associated with migration for work, jobs in the informal economy Emerging forms of employment, e.g. self-employment, outsourcing, temporary contracts They may be more widely recognized through better scientific understanding, e.g. the effects of ergonomic risks on musculoskeletal disorders. They may be influenced by changes in perceptions about the importance of certain risk factors, e.g. the effects of psychosocial factors on work-related stress. Theme for 2026 "Let's ensure a healthy psychosocial working environment" is the theme for 2026. The psychosocial working environment is defined by how work is designed, organized and managed, and the organizational practices that shape everyday working conditions. Psychosocial factors – such as workload and working time, role clarity, autonomy, support, and fair and transparent processes – strongly influence how work is experienced and affect workers’ safety, health and performance. When psychosocial factors harm workers, they become hazards which, alongside physical, chemical and biological types, must be addressed and managed to ensure safe and healthy working environments.
