Storage and transportation
Transportation precautions: Close operation and strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type dust masks to avoid generating dust. When handling, it is important to load and unload with care to prevent damage to the packaging and containers.
Storage precautions: Sodium hydroxide should be stored in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. The storage temperature shall not exceed 35 ℃ and the relative humidity shall not exceed 80%. The packaging must be sealed and not damp. It should be stored separately from flammable materials, acids, etc., and should not be stored together. The storage area should be equipped with appropriate materials to contain leaked materials. Solid sodium hydroxide is tightly sealed in 0.5mm thick steel drums, with a net weight of no more than 100 kilograms per drum; Plastic bags or two-layer kraft paper bags with full or medium opening steel drums on the outside; Screw mouth glass bottles, iron cap pressure mouth glass bottles, plastic bottles or ordinary wooden boxes outside metal barrels (cans); Screw mouth glass bottles, plastic bottles, or tin plated thin steel drums (cans) filled with bottom plate lattice boxes, fiberboard boxes, or plywood boxes; Tin plated thin steel drums (cans), metal drums (cans), plastic bottles or corrugated cardboard boxes with metal hoses. The packaging container should be complete, sealed, and clearly marked with "corrosive substances".
