What type of extinguisher should be initially used on electronic device fires?

The most suitable type of extinguisher for initial use on electronic device fires is a Halon extinguisher. Halon extinguishers are particularly effective on Class C fires, which involve energized electrical equipment. They work by disrupting the chemical reaction that sustains the fire, effectively smothering it without leaving residue that could damage sensitive electronic components.

Halon is specifically designed to extinguish fires without harming electronics, making it the ideal choice for situations where electronic devices are involved. This property is vital when considering how to protect the equipment and the surroundings while ensuring safe fire suppression.

Other types of extinguishers, like foam or water, may not be suitable for electronic fires as they can conduct electricity or leave residues that could damage the equipment or create safety hazards. DCP (Dry Chemical Powder) extinguishers, while effective on many types of fires, can also leave residue that may not be ideal for sensitive electronic environments. Thus, Halon extinguishers are the recommended choice for immediate use in such fire situations.
