Consider the characteristics of chemical substances

Corrosive substances: If the plastic bucket is filled with corrosive chemicals such as strong acids and alkalis, special attention should be paid to preventing leakage when stacking. Firstly, it is necessary to confirm that the quality of the square bucket is intact, without cracks or holes. Before stacking, carefully inspect the barrel body, especially the bottom and seams of the barrel. For square buckets with minor damage, they should be stored separately and promptly disposed of. For example, for plastic buckets containing sulfuric acid, once leaked, the sulfuric acid will corrode the surrounding buckets and the ground, triggering a chain reaction.

Flammable and explosive substances: For square drums containing flammable and explosive chemicals, the stacking environment must comply with fire prevention (based on actual reports) and explosion prevention (based on actual reports) requirements. Adequate safety distance should be maintained between the square buckets to prevent the spread of fire or the mutual influence of fragments generated by explosions in case of accidents. Meanwhile, the stacking area should be kept away from sources of fire, heat, and static electricity. For example, in the plastic bucket stacking area where gasoline is stored, any open flames and equipment that may generate electric sparks must be prohibited from entering, and all equipment must be well grounded to avoid static electricity accumulation.

Toxic substances: When the square bucket contains toxic chemicals, stacking should consider preventing the leakage of toxic substances and personnel contact. The stacking method should be stable to avoid toxic substance leakage caused by the dumping of square buckets. In addition, the stacking area should have good ventilation conditions so that toxic gases can be promptly discharged in case of minor leaks, reducing the harm to personnel. For example, in a plastic bucket stacking warehouse containing cyanide, the ventilation system should be protected to ensure that the air can be updated at a suitable speed and reduce the concentration of cyanide gas indoors.

Stacking method and stability

Reasonable arrangement method: Plastic square barrels in the chemical industry can be stacked neatly or staggered. Neat arrangement facilitates management and quantity calculation, suitable for situations where the specifications of square buckets are uniform and the stacking height is low. Interlocking stacking can increase the stability of stacking and make the weight distribution more uniform. For example, when stacking large plastic buckets, a staggered stacking method is used, where the upper buckets are placed at the seams of the lower buckets, which can effectively prevent the buckets from tipping over when subjected to external forces (such as minor collisions).

Use auxiliary tools: To enhance the stability of stacking, auxiliary tools such as pallets, shelves, or stacking racks can be used. The pallet can facilitate forklift handling and elevate the square bucket to prevent moisture or corrosion at the bottom. Shelves and stacking racks can fix the position of square barrels to prevent them from sliding or tipping over. For square drums containing hazardous chemicals, using these auxiliary tools can also facilitate the setting of isolation and protective measures. For example, in warehouses storing hazardous chemicals, placing plastic buckets on shelves with protective barriers can reduce the spread of chemicals in the event of bucket leaks or other accidents.
