👉 Red fumes often indicate the presence of carbon monoxide (CO), a colorless, odorless, and highly toxic gas. These fumes can originate from various sources, including faulty or poorly maintained combustion processes in engines, stoves, or industrial equipment. When CO is released into the air, it can quickly accumulate, especially in enclosed spaces with poor ventilation, leading to serious health risks such as headaches, dizziness, nausea, and in severe cases, death. The distinctive red color of the fumes is due to their high concentration and the way they scatter light, making them more visible and alarming. Immediate action, such as opening windows or evacuating the area, is crucial if you detect these fumes.
