1. Sodium hydroxide is slightly corrosive to glass products, and both will generate sodium silicate, which makes the piston in the glass instrument stick to the instrument. Therefore, glass stoppers should not be used when containing sodium hydroxide solution, as this may cause the cap to fail to open.
2. If the glass container is filled with hot sodium hydroxide solution for a long time, it will also cause damage to the glass container.
3. Sodium hydroxide should be stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The storage temperature does not exceed 35 °C, and the relative humidity does not exceed 80%. The package must be tightly sealed and never get wet. It should be stored separately from flammable (combustible) materials and acids, and should not be mixed. The storage area should be equipped with suitable materials to contain the spill. Solid sodium hydroxide is packed into 0.5 mm thick steel drums and tightly sealed, and the net weight of each drum does not exceed 100 kg; plastic bags or two-layer kraft paper bags with full or medium opening steel drums; Ordinary wooden boxes outside screw-mouth glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans); Screwed glass bottles, plastic bottles or tinned thin steel plate barrels (cans) with full bottom plates, lattice boxes, fiberboard boxes or plywood boxes; Tinned thin steel sheet drums (cans), metal drums (cans), plastic bottles or corrugated boxes with metal hoses. The packaging container should be intact, airtight, and clearly marked with "corrosives".
