Why can cleaning a ship's cargo hold pay $30,000? Yet almost nobody wants to do it. Because this ship was carrying coal on its last trip. But the next transport food. The real problem is the leftover coal dust. These tiny particles are as fine as flour. They can hide inside welds, corners and small gaps that are extremely difficult to clean. Even when the cargo hold looks spotless, can still leave black dust on your hands. For food transportation, any contamination can cause serious problems. Even a small amount of coal residue could lead to a shipment being rejected. First, workers remove large chunks of up dirt and coal. Then they use professional equipment to vacuum away the fine dust hidden in hard to reach areas. Places machines cannot reach must be cleaned by hand, sometimes requiring workers to crawl into tight spaces. But the job isn't over yet. The entire cargo hold must be washed repeatedly with high pressure water to remove dirt, rust and hidden residue. After that, the inside must be completely dried because it absorbs moisture during transportation or develops mold. Finally, inspectors check the entire cargo hold and confirm it meets all safety requirements before the ship can load new cargo. This dirty and exhausting a coal ship for $30,000?
