👉 Expanding fumes refer to the visible, often pungent plumes of gas or vapor that emanate from a leak or source of contamination, typically indicating a chemical release or combustion process. These fumes can be a sign of various hazards, such as toxic gases like carbon monoxide, hydrogen sulfide, or volatile organic compounds (VOCs), which can pose serious health risks if inhaled. The expanding nature occurs as the gas rapidly disperses into the surrounding air, pushing outward and spreading in all directions until it mixes with the atmosphere. This phenomenon is often accompanied by a distinctive odor, which can vary depending on the type of fumes present, serving as an early warning sign of potential danger.
