👉 Treat fumes are a noxious mixture of volatile organic compounds released when certain materials, often found in cleaning products, air fresheners, and personal care items, decompose or evaporate. These fumes can include ammonia, formaldehyde, and other irritants that cause respiratory issues, headaches, and eye irritation. The strong, pungent odor is a clear warning sign of their presence, making it essential to ventilate spaces promptly and use caution when handling or disposing of products containing these chemicals.
