Stack one end at the same time according to the tree species, wood species, grade and specification, and leave a slope along the stack; The square crib is closely arranged, and the slope is reserved for capping, and the gap is reserved for the wood with large water content; Those with moisture content requirements shall be placed in the material warehouse or shed

3. When selecting the stacking point, keep away from the places where there are open flames (boilers, chimneys, kitchens, etc.) in the dangerous goods warehouse, and have signs prohibiting fireworks and fire-fighting equipment to prevent fires

4. The removed wood formwork and supporting materials shall be sorted and stacked at any time, and the formwork and supporting materials shall be stacked separately

1. Stack them in a dry and ventilated warehouse according to the variety, specification, grade and quantitative order. If they are temporarily stored in the open air, they must be covered under the mat. It is forbidden to put them together with damp and volatile substances (acid, alkali, salt, lime, grease, alcohol, etc.)

2. When stacking, the box cover shall be upward, and shall not be tilted or placed horizontally, and shall not bear heavy pressure or collision; Stack height: no more than 3 layers for 2~3mm thick and no more than 2 layers for 4~6mm thick; The bottom skid shall not be less than 10cm; Bulk glass shall be stored separately

3. Check the storage of glass frequently, and deal with wet, moldy and broken glass in time

4. During loading and transportation, the packing box should be upright, the box head should be forward, and the boxes should be close to each other. Shaking and collision should be avoided; Stand upright and handle with care during loading and unloading

VII. Hardware products

1. Quantitatively stack them in a dry and ventilated warehouse according to variety, specification, model, place of origin, material and tidy order

2. Keep the package intact during storage, and do not mix with chemical materials such as acid and alkali to prevent corrosion

3. The distribution shall be based on the principle of first in, first out. In case of rust, it shall be handled in time, and the screws and nuts shall be painted with antirust paint in time

VIII. Plumbing equipment

1. Neatly stack them according to the variety, specification and model, stagger and bite each other, invert the heavy code, and the height is not more than 1.5m. The radiator has a bottom skid, and the height is not more than 1m

2. For small caliber and threaded accessories, keep the package intact to prevent bumping against damp dust

IX. rubber and plastic products

1. They are neatly and quantitatively stacked in the warehouse according to variety, specification, model and ex factory date to prevent rain and sun. Jean Claude Steinmetz, chairman of China Europe Automotive Materials Committee (apimc), and Cao Du, executive chairman of ialta/Vice President of Chang'an Automotive Engineering Research Institute, presided over the launching ceremony of the selection of the ialta (China) automotive lightweight green technology innovation award, which is high temperature proof

122 silicone structural seal for building 2. It is strictly forbidden to contact with acids, alkalis, Oils and chemicals to prevent corrosion and aging

3. The storage is to keep the package intact, grasp the principle of first in, first out, and prevent deformation and aging

Xi. Waterproof materials

1. The bottom of asphalt material should be solid and flat, and isolated from the natural ground. It is strictly prohibited to mix with other large piles of materials

2. Ordinary linoleum shall be stored in the warehouse or material shed, and shall be placed vertically. The stacking height shall not exceed 2 layers. It is forbidden to stack horizontally or obliquely. When the glass cloth felt is placed horizontally, the stacking height shall not exceed 3 layers

3. Other waterproof materials shall be subject to the storage requirements of paint chemical materials

XII. Other light decoration materials should be stored

2. Waterproof and windproof measures shall be taken to enclose and cover; Gypsum products shall be stored in warehouses or sheds and stacked vertically

XIII. Materials transfer tools in the paper packaging industry

1. Dismantle, adjust and maintain them at the same time, and stack them neatly

2. Buckle the combined steel formwork (or buckle the top layer); The large formwork shall be erected on the opposite side, and the self stabilizing angle shall be controlled between 17 and 18; Steel scaffold tubes shall be equipped with bottom pads, which shall be classified according to the length and stacked at one end; Steel supports and steel springboards shall be stacked upside down in layers, and the height shall not exceed 1.8m; All kinds of fasteners and accessories shall be stacked in a centralized manner, and fences shall be set

3. Steel and iron materials shall be padded and covered to prevent corrosion and damage caused by rain and moisture

according to the management requirements of on-site materials and tools, combined with the actual situation of the site, implement the division of labor responsibility system, daily inspection and regular inspection system, and rectify problems in time to ensure that the management of on-site materials and tools meets the standard. Reduce human and natural consumption and reduce production costs. We should really increase production and save money, increase efficiency and save expenses
