Lead compounds in paints (mostly pigments and driers) meet strict technical requirements but are nevertheless extremely hazardous to the environment and to human health. Small and Medium-sized Enterprise (SMEs) should not use any raw materials containing lead and should seek to ensure low levels of lead in raw material ingredients. The Technical Guidelines indicate the hazards of lead compounds and their alternatives by referring to the conventions of the Globally Harmonized System of Classification and Labelling of Chemicals* (GHS). The GHS facilitates the definition and classification of the hazards of chemical products and communicates health and safety information on labels and safety data sheets. The Technical Guidelines on Lead Paint Reformulation were developed to help address both capacity constraints and technical barriers to the substitution of lead compounds in paints with focus on the needs of SMEs for the effective and efficient reformulation of paint.
