The Framework will guide the Dialogue’s priorities and actions through four working groups on: Regulatory Cooperation and Convergence; the Globally Harmonised System of Classification and Labelling of Chemicals (GHS); Marine Debris, a cross-cutting initiative to promote development of and investment in innovative solutions to land-based waste management; and Data Exchange, which enables the sharing of data and information on chemicals management. (SDG)

The first step to ensure safety is obviously to identify the level of toxicity of chemicals. This is done by applying the GHS classification and its hazard communication system that provides users, workers and emergency responders with all the relevant information concerning the product itself, its hazards, the packaging and containers to be used for safe transport and storage, precautions to be taken and first aid.
