Sodium hydroxide (caustic soda) is a highly corrosive material transported as solid (UN1823) or solution (UN1824) under Class 8 hazardous goods regulations. It must be shipped in airtight, moisture-proof containers—such as steel drums, lined jumbo bags, or dedicated rubber-lined tank cars—to avoid hydration and corrosion, keeping away from aluminum, zinc, and acids.
Transport Guidelines & Safety
- Packaging: Solid flakes require double-layer polyethylene-lined paper bags or 1000 kg jumbo bags with liners. Solutions are typically transported in 10,000–18,000 gallon DOT-103/111A100W1 insulated tank cars.
- Storage & Moisture: Because it is highly hygroscopic, it must be stored in cool, dry, well-ventilated areas with moisture protection.
- Safety Requirements: Personnel must wear protective clothing (gloves, safety goggles, face shields) to avoid severe tissue damage.
- Material Compatibility: Use plastic (HDPE, XLPE), stainless steel, or FRP containers. Avoid aluminum
Emergency & Handling
- Spills: Contain spills with inert material (sand/earth).
- Labeling: Must be labeled UN1823 (solid) or UN1824 (solution) as corrosive.
