The Code requires PCBUs to identify every chemical at the workplace that meets GHS classification criteria. This includes chemicals generated as by-products or waste. Identification relies on Safety Data Sheets (SDS), labels, and the GHS. The register of hazardous chemicals must be maintained and kept up to date. Failure to identify hazards is a prerequisite failure affecting all downstream control obligations.
