👉 Replica fumes refer to the odorless, invisible vapors that can be released when certain materials, especially plastics and synthetic fabrics, are burned or exposed to high temperatures. These fumes mimic the smell of real plastics, often described as acrid, chemical, or petroleum-like, and can linger in the air for extended periods. They pose a health risk because they can irritate the eyes, nose, and throat, and in some cases, may cause respiratory issues or allergic reactions. Common sources include incinerators, pyrolysis plants, and even some household items like plastic toys or furniture treated with flame retardants. Proper ventilation and protective measures are essential when dealing with environments where replica fumes might be present.
