Definition & Explanation
From the moment a shipper begins preparing corrosive substances – acids, alkalis, and chemically related materials – for dispatch, the Class 8 classification under the UN dangerous goods framework applies. The correct UN number depends on precise chemical composition and physical state; different acids or bases may require entirely different codes. Packaging must use UN-certified containers, and both hazard labels and orange placards are mandatory on the vehicle. Drivers and warehouse personnel must be trained in emergency response and equipped with appropriate PPE, including gloves, eye protection, and respiratory equipment where required. Class 8 is distinct from Class 6.1 (toxic substances): corrosivity describes the destructive effect on tissue and materials, not necessarily systemic poisoning.
