Working with government agencies, employers and trade unions, the ARLs are required to undertake activities to prevent industrial accidents and occupational diseases in affiliated companies with ten or more employees. Their main focus is on physical hazards, but they also address chemical risks. Consideration should be given to how the provision of information could be extended to smaller companies, which often lack the resources and capacities to manage chemicals, even those whose hazards are well known. Another important information gap concerns the safe disposal and treatment of chemical waste from industrial and agricultural processes.
