The international standards for "five distances" of warehouse racking generally refer to the top distance, lamp distance, wall distance, column distance, and stack distance.
The following is a detailed introduction to the "five distances":
1. Top Distance
- Definition: The distance between the top surface of the stacked goods and the warehouse roof.
- Standard: Generally 30 centimeters or more (for gable roofs, the top surface of the stacked goods should not exceed the beams).
2. Lamp Distance
- Definition: The distance between the fixed lighting in the warehouse and the goods.
- Standard: No less than 50 centimeters, to prevent the heat generated by the lamps from igniting the goods when they are too close.
3. Wall Distance
- Definition: The distance between the wall and the stacked goods.
- Standard: No less than 50 centimeters (exterior wall), for ventilation, heat dissipation, and fire prevention. In case of a fire, it allows access for firefighters.
4. Column Distance
- Definition: The distance between the goods stack and the columns.
- Standard: No less than 30 centimeters. The purpose of the column distance is to prevent moisture from the columns from affecting the goods and to protect the column base to avoid damaging the building.
5. Stack Distance
- Definition: The distance between stacks of goods.
- Standard: No less than 100 centimeters. The purpose of the stack distance is to keep the stacks of goods clearly separated to prevent confusion, facilitate ventilation checks, and aid in rescue and evacuation of goods in case of fire.
The international standards for the "five distances" of warehouse racking are important regulations to ensure the safe operation of the warehouse, including top distance, lamp distance, wall distance, column distance, and stack distance.
Following these standards helps prevent fires, improve operational efficiency, and protect goods quality.
