Container Cleaning Procedures
Containers are exposed to various climatic conditions and environments and face extreme weather at sea and in ports. They come into contact with harmful pathogens such as mold, bacteria, and viruses, along with pollen, liquids, and other hazardous materials. Dirty and contaminated containers promote the growth of fungi, bacteria, and mold, which can be harmful to the crew during loading and unloading of cargo.
Container Cleaning Procedures
The cleaning and disinfection of containers are of critical importance for the safety of the crew handling the cargo, as well as for the broader protection of local ecosystems. This helps prevent the introduction of invasive pests, which can be very difficult to eradicate once they establish themselves in an area.
Container Cleaning Procedures
Containers travel all over the world, which means they carry a variety of microbes and pollutants that could be harmful to those handling them and to the environments they pass through. Due to this high exposure to microbes and contaminants, thorough cleaning of containers before delivery to the shipper is an important and mandatory step to protect human health and maintain global ecological balance.
Steps to Follow When Cleaning
Containers Sweeping
Wearing a mask, cleaning personnel should remove all visible dust and debris using a heavy-duty broom, starting from the back of the container and moving toward the front. After sweeping, a powerful vacuum cleaner should be used to remove the more stubborn dust particles.
Blowers (Leaf Blowers)
For ventilating the container, blowers and air compressors are very useful. A powerful blower removes invisible insects, pollen, and seeds.
Pressure Washing
According to standard practice, the interior of the container is washed with a high-pressure water jet, starting from the front toward the back, paying special attention to the corners, walls, and ceiling. Unlike a regular hose, high-pressure water effectively removes stubborn dirt and contaminants. During this process, personnel must wear protective goggles to shield their eyes from debris. Pressure washing also helps identify dents, small cracks, and other damages that require immediate repair. After cleaning the interior, the same procedure should be performed on the exterior of the container.
Visual Inspection
After washing, a detailed visual inspection must be performed to detect cracks, dents, and corrosion. If such seemingly minor issues are ignored, they can lead to serious problems requiring major repairs or even reduce the container’s lifespan. The visual inspection should also identify contaminants such as plants, seeds, insects, eggs, and snails. Any holes can be sealed with welded metal patches or with specialized industrial sealants.
Using Sandpaper and Wire Brush
Medium-grit sandpaper (100–150 grit) or a belt sander is used to remove peeling paint, rust, and stubborn stains. Sanding should only be performed once the container surface is completely dry. Care must be taken to ensure that vents are not blocked during the process.
Painting
Generously applying primer helps restore the container’s original appearance. This additional coating also provides protection against corrosion.
Conclusions
Shipping containers move from port to port, crossing oceans and numerous international maritime borders. They come into contact with hazardous liquids, insects, pollen, and various unwanted materials that can cause problems in new ecosystems where they arrive. Invasive pests can be transported to remote areas through the trade of agricultural and forestry products. Strict adherence to cleaning procedures significantly contributes to the safety of personnel handling the containers and to environmental protection. Keeping containers clean and in good condition also greatly extends their lifespan, preventing corrosion and structural weakening.
