Halon fire extinguishers were primarily deployed for combating fires involving sensitive electronic equipment, flammable liquids, and gases. These extinguishers employed halon, a liquefied, compressed gas that interrupts the chemical reactions occurring during combustion. They were particularly effective in situations where water-based extinguishers could cause significant damage, such as in computer rooms, aircraft, and museums.
The benefit of using halon stemmed from its ability to extinguish fires without leaving a residue. This characteristic was crucial in preserving delicate equipment and preventing further damage beyond the fire itself. Historically, halon was widely adopted due to its efficiency and cleanliness; however, environmental concerns regarding its ozone-depleting potential led to its eventual phase-out under international agreements.
