Which Halon has been widely used in portable extinguishers?

Explanation:
In handheld extinguishers, the goal is quick, clean fire knockdown with minimal residue. Halon 1211 fits this role best because it vaporizes readily and delivers a fast-acting gas that blankets the flame, interrupting the chemical reactions that keep the fire going. This makes it highly effective for small, localized fires and electrical equipment, where you want a rapid effect without leaving corrosive or damaging residue. The other halons are typically used in fixed or specialized suppression systems rather than portable units, so they aren’t the standard choice for handheld extinguishers. Also, halons deplete the ozone layer, so their use is now restricted and alternatives are often pursued.
