What type of fire extinguisher should be used for electrical fires? A comprehensive guide to fire‑extinguishing methods and agents for energized equipment and electrical circuits.
2026-08-25
Electrical fires are a type of fire caused by short circuits, overloads, or electrical arcs in electrical equipment, wiring, or energized systems. When the power has not been disconnected, extinguishing electrical fires requires the use of non-conductive, highly insulating fire‑extinguishing agents; otherwise, there is a risk of electric shock and the fire may spread further. In general, carbon dioxide extinguishers or clean‑agent extinguishers (such as heptafluoropropane or perfluorohexanone) are preferred for initial suppression of electrical fires. In settings such as distribution rooms, computer rooms, and areas housing precision equipment, clean‑gas fire‑suppression systems (e.g., IG100, IG541) should be employed to prevent damage to the equipment.
On June 17, 2026, the National Fire and Rescue Administration held its regular press conference. Spokesperson Wang Tianrui noted that among 20 major fire incidents, electrical fires accounted for a significant share. Specifically, 13 of these major fires were caused by electrical factors, representing 65% of the total. For fires involving energized equipment, the primary firefighting requirement is to use extinguishing agents that are electrically insulating and non-conductive. Under no circumstances should water or foam extinguishers be used on live circuits; while dry chemical extinguishers can suppress flames, they may cause irreversible damage to sensitive electronic devices.
Q1: What type of fire extinguisher should be used for electrical fires? Which fire extinguisher is suitable for extinguishing fires in electrical circuits?
A: Electrical and circuit fires are classified as Class E fires, which involve energized equipment. If the power has not been disconnected, an insulating, non-conductive extinguishing agent must be used.
For initial fires in household small outlets and distribution boxes, carbon dioxide fire extinguishers are suitable. Distribution rooms, server rooms, and precision instrument rooms should be equipped with clean‑gas fire suppression systems; common types include heptafluoropropane, perfluorohexanone, IG100, and IG541, which provide residue‑free extinguishing and do not damage electronic circuits.
Q2: What type of fire extinguisher should be used to put out fires involving energized equipment?
A: Extinguishing fires involving energized equipment falls into two scenarios:
On-site emergency firefighting: Carbon dioxide fire extinguishers offer strong insulation and leave no residue; dry powder fire extinguishers are suitable only for temporary emergencies and should not be used on precision equipment.
Long-term protection for computer rooms, electrical control cabinets, and energy storage compartments: Clean agent systems are preferred; perfluorohexanone, heptafluoropropane, IG‑100, and IG‑541 can all be used to directly extinguish energized fires.
Q3: What type of fire extinguisher should be used to put out fires involving precision instruments?
A: Dry powder is strictly prohibited for precision instruments, servers, and laboratory equipment, as the powder can corrode chip circuit boards. Four clean gases are recommended: perfluorohexanone, heptafluoropropane, IG100, and IG541. Among these, perfluorohexanone offers the best protection for precision equipment and is particularly suitable for lithium‑battery compartments and high‑end computing data centers.
Only by shifting from “post‑incident tripping” to “proactive prevention” can electrical fire risks be fundamentally reduced.
Xinlin Fire Department Is Full coverage of the four major clean-gas agents for a small number of applications. The original manufacturer; all products in the entire product line use pharmaceutical-grade ingredients. High-insulation clean dielectric It can be discharged directly while energized, addressing the critical challenge of extinguishing electrical fires without first de-energizing the equipment, and comprehensively covers all scenarios involving electrical fires: heptafluoropropane, perfluorohexanone, IG100 pure nitrogen, and IG541 mixed gas. It is also available with complementary automatic fire‑detection tube systems, portable clean‑agent extinguishers, and dedicated fire‑extinguishing modules for switchgear cabinets. From small distribution boxes and lithium‑battery energy storage cabinets to high‑ and low‑voltage switchrooms, large data centers, and precision laboratory instruments, there is a corresponding complete set of equipment for each application—eliminating the need to source components from multiple suppliers and enabling one‑stop procurement of a fully integrated electrical fire‑protection system.
Unlike mere equipment resellers, Xinlin offers end-to-end electrical fire‑protection services: on‑site assessments of distribution rooms, server rooms, and energy‑storage compartments; free development of tailored electrical‑fire suppression plans; an in‑house construction team well-versed in high‑ and low‑voltage distribution and data‑center cabling standards, ensuring no damage to existing electrical systems; local warehousing for rapid delivery; and one‑stop after‑sales support—including equipment recharging, annual inspections, and system maintenance—to ensure the long-term reliability and availability of your electrical fire‑protection system.
Prioritize disconnecting the power supply before extinguishing fires; if power cannot be disconnected, only use non-conductive extinguishing agents. Dry powder extinguishers are prohibited in areas housing precision equipment. For critical protection zones, it is recommended to install an automatic gaseous fire suppression system to promptly address incipient fires and minimize equipment damage.
