👉 Entry fumes are noxious gases and vapors released into the air when a vehicle, particularly an engine, is first started or when parts of it are exposed to high heat. These fumes can contain a variety of harmful substances, including carbon monoxide (CO), hydrocarbons, and particulate matter, which pose significant health risks such as respiratory irritation, headaches, dizziness, and in severe cases, even death. The composition and intensity of entry fumes depend on factors like the fuel type, engine condition, and environmental conditions, making them a critical concern for both drivers and those in close proximity to idling vehicles.
