👉 Fumes are invisible, odorless gases or vapors that can be released from various sources, including chemicals, fuels, and certain materials when they heat up, burn, or decompose. These substances can pose significant health risks if inhaled, as they may irritate the respiratory system, cause long-term damage, or even lead to poisoning. Common sources of fumes include industrial processes, vehicle exhaust, cleaning products, and household chemicals like paints, solvents, and air fresheners. Proper ventilation and safety precautions are essential to minimize exposure and protect health.
