ASEAN Guidelines for Occupational Safety and Health C2: Suppliers classify every chemical supplied for use at work against the Schedule I hazard classes, by a trained classifier, using available data, bridging principles and cut-off limits, and review the classification

What does C2 require?

Anyone supplying chemicals for workplace use has a duty to classify them into the hazard classes set out in Schedule I. Classification identifies the relevant hazard data, reviews it and decides whether and to what degree the substance or mixture is hazardous against the agreed criteria. Mixtures are classified on test data for the whole mixture where it exists, otherwise by the GHS bridging principles, and for health and environmental classes by the estimation methods in the GHS where neither is available. Data generated under earlier systems is accepted; the generic cut-off values and concentration limits apply unless the supplier knows an ingredient is hazardous below them. A person trained in GHS classification does the work, and classifications are reviewed periodically and whenever significant new information appears.
