GHS is an international hazard classification system for chemicals created by the United Nations. The system aims to protect human health and the environment during chemicals’ handling, transport, and use by ensuring that information on the substances’ physical hazards and toxicity is available. As a UN initiative, the GHS aims to harmonize rules and regulations on chemicals on the national, regional, and worldwide levels.
