ASEAN Guidelines for Occupational Safety and Health C3: Suppliers label every container of hazardous chemical with product identity, pictograms, signal word, hazard and precautionary statements and supplier contact, applying precedence rules, firmly affixed and reviewed at least five-yearly

What does C3 require?

A supplier labels the containers of hazardous chemicals supplied for use at work, applying the Schedule III cut-off values. Each package is marked clearly and indelibly with the product and component names, the Schedule I pictograms, the signal word danger or warning, the hazard statements and the Schedule II precautionary statements, and the principal supplier's name, address and phone number; pictograms, signal word and hazard statements sit together, and claims such as non-toxic or non-harmful are prohibited. Precedence follows the UN transport rules for physical hazards and the GHS health-hazard rules (skull and crossbones or corrosive symbol over the exclamation mark, danger over warning, all hazard statements shown with danger statements first). Labels are fixed so they read horizontally with the package upright, tags are used where the surface cannot carry a label, dimensions may be set by the competent authority, and labels are reviewed every five years or sooner when new and significant information changes the classification.
