How did the fire on the Hue City reportedly start?

The fire on the Hue City reportedly started due to rags in the uptakes. This indicates that the accumulation of flammable materials, such as rags, in areas where exhaust gases pass through can create a significant fire risk. When these rags become heated by the exhaust or other factors, they can ignite and lead to a larger fire. This situation highlights the importance of proper maintenance and cleanliness in areas of equipment where hot exhaust flows, ensuring that any combustible materials are removed regularly. The buildup of debris can present serious hazards, emphasizing the need to adhere to safety protocols and conduct thorough inspections to prevent such incidents from occurring.
