👉 Narrow fumes refer to a type of airborne contaminant that is highly concentrated and limited in volume, often originating from specific sources such as industrial processes, chemical reactions, or the burning of certain materials. These fumes are typically small in size and can penetrate deeply into the respiratory system, posing significant health risks if inhaled over prolonged periods. They are characterized by their low density and can spread quickly in enclosed spaces, making them particularly dangerous in environments like factories, laboratories, or areas with poor ventilation. The narrow nature of these fumes means they can be difficult to detect without specialized equipment, but their concentrated form makes them highly irritating and potentially harmful to human health.
