6 Things to Learn Refrigerant Packing Requirement
Refrigerant packaging is an essential part of refrigerant transportation. This article introduces the refrigerant packing requirements from three aspects.
Refrigerant transportation is generally preferred by sea, so the refrigerant packing must comply with the inspection requirements of the container.
External inspection for refrigerant container
1) The main frame of the container is complete, and IMO CSC specifies no severe structural defects;
2) The box walls, bottom, and top are in good condition and should not have any obvious deformation;
3) There should be no breaks near or on the inside where there are bends, dents, creases, scratches, etc., on the outer surface. There should be no traces of water leakage caused by loose or broken rivets at the joints of the outer panels;
4) The air holes on the top of the box should be free from damage and water accumulation;
5) The parts that have been repaired should be in good condition and have no leakage;
6) The safety certificate plate fixed on the container surface should be displayed, and the content should be valid;
7) Except for permanently fixed marks and symbols, any signs, marks, emblems, etc., previously used on the container should be removed;
8) There should be no signs of secondary contamination along the bottom ribs of the container, inside the forklift slot, inside and outside of the twist lock fittings, bottom, and cross-connections;
9) The inspection date shall be the next one printed on the container safety license plate;
10) If the inspection date exceeds the date of the next inspection, the mark of the continuous inspection plan “ACEP” should be marked on or near the safety license plate.
1) Before entering a closed container, the door should be opened for some time to make the atmospheric environment inside the container consistent with the outside air. Care should be taken to take necessary measures to prevent animals and insects from entering the container while the door is open;
2) The container should be clean and dry, free of residues and persistent odors from previously loaded goods;
3) There should be no leaks in the parts that have been repaired. You can find potential leaks by closing the door and observing whether there is light leakage;
4) There should be no significant damage in the box, and the floor should not be damaged or protruding objects that may cause personal injury or damage to the goods, such as nails, screws, unique accessories, etc;
5) There should be no traces of moisture on the inner lining of the box wall. If traces of water are found, the cause of the trails should be identified;
6) Angle hooks, fastening rings, and other fasteners used to secure cargo should be in excellent and usable condition. If heavy objects are connected in the container, the container operator should be contacted in advance to obtain relevant information, such as the strength of the fasteners and securing methods;
Refrigerants are hazardous chemicals, so refrigerant packaging must comply with dangerous goods packaging operations.
Refrigerant Packing requirements
1) Refrigerant packing according to the 5.2 stowage plan;
2) During the packing process, it should be handled with care and should not be shouldered, carried, bumped, dropped, or rolled to prevent damage to the packaging;
3) The lids and bottle caps of packages should be facing upwards and should not be turned upside down. The ventilation hole of the box should be upward and not blocked;
4) Damaged, leaking, or leaking packages should not be shipped. Suppose the refrigerant packing of dangerous goods is damaged, leaks, or leaks during packing. In that case, it should be immediately and effectively disposed of according to the characteristics of the goods under the supervision of the on-site container packing inspector;
5) If leaking dangerous goods may cause an explosion, spontaneous combustion, poisoning, or similar significant dangers, personnel should be evacuated to a safe area immediately, and the relevant emergency departments should be notified;
6) When dangerous goods requiring refrigeration are loaded, the cargo packages should be pre-cooled to ensure the loading temperature meets the minimum control temperature requirements;
7) If the loaded goods have other special requirements, those requirements shall apply.
Pad Requirements for Refrigerant Packing
1) When different goods are loaded in the box or packaged in different forms, effective padding materials should be partitioned between the goods;
2) Effective padding materials should be used between the upper and lower layers of barrel-packed dangerous goods to disperse the cargo load on the upper layer. The top of the more insufficient barrel packaging and the bottom of the upper barrel packaging is designed to be an embedded structure that closely matches each other, and the barrel packaging of the bottom cargo has sufficient strength and does not require a liner;
3) The space between the goods in the box and the box wall should be tightly packed with effective lining material to prevent the goods from moving;
4) The liner should have sufficient protective strength to effectively prevent damage caused by vertical or horizontal displacement of the goods in the container during transportation;
5) When using pallets, plywood, wooden slats, wooden boards, and other types of liners, they should be supported on the corner posts, corner pieces, end posts, and side posts of the container to avoid keeping the side wall panels and door panels, causing side wall panels to collapse. , The door panel of the box is damaged.
Securing dangerous goods in containers
1) The goods in the container should be secured to prevent movement. The cargo should be secured in a manner that should not cause damage to the cargo or container;
2) Securing materials (such as steel wire ropes, fiber ropes, steel belts, nylon belts, airbags, telescopic rods, protective nets, adhesive tapes, etc.) should have sufficient strength to withstand various stresses caused by changes in transportation acceleration. Stress and should not cause safety hazards to dangerous goods in the box;
3) The fasteners used inside the container should have locking devices. After fastening, all pins should be locked to prevent the buckles from loosening and lowering due to vibration and swing during transportation—fastening effect;
4) The use of airbags should meet the following requirements:
a) When using airbags, the requirements for filling pressure and maximum gap width in the product instructions should be followed. Taking into account the temperature inside the container
There is a possibility of an increase or decrease, and a margin should be left as appropriate when filling the airbag.
b) When using airbags to fill the gap at the door of the box, precautions should be taken to prevent the airbag from causing the door to suddenly open during unpacking operations.
c) If the surface of the gap is uneven and there is a risk of scratching or puncturing the airbag, appropriate measures should be taken to keep the surface of the gap reasonably smooth;
5) When using nails to fix, the pins or nail caps should not be exposed.
Finally, the refrigerant must meet gas refrigerant packing requirements
1) Containers with oil stains inside should not be used;
2) Do not wear oil-stained work clothes and use oil-stained gloves for work;
3) Cylinders should meet the following requirements:
a) The safety helmet should be tightened, and there should be no peculiar smell. If the bottle cap is loose, effective tightening measures should be taken.
b) The bottle wall is free of corrosion, dents, and damage.
c) Other accessories (such as valves, bottles, and paint colors) should comply with product standards.
d) The protective apron of the cylinder should be complete;
4) Do not hold the safety helmet of the cylinder during operation, and do not throw, collide, or slide;
5) Cylinders should be packed in pallets or groups to prevent cylinders from rolling in the box. Wooden boards should isolate the walls and ends of the box;
6) When stacking, the safety caps of the cylinders in the box should be in the same direction.
