Electrical fires are much more common than one might think and represent a serious risk in professional environments. Because when electrical equipment is abundant, a minor short circuit can quickly turn into a disaster. In this article, we will explore together the best practices and solutions available to prevent electrical fires, whether they occur in a home or in professional premises.
📋 The essentials at a glance: Personally, I consider electrical safety to be the most critical renovation aspect in a dwelling. Did you know that 25% of domestic fires in France are electrical in origin? Adopting the right protections and eliminating bad plugging habits can reduce the risk of accidental fire starts by four times.
Having an idea of the risks involved
Even before considering buying a fire extinguisher for electrical fires, it is important to ensure that your electrical installation complies with standards. If you are a company, it should be known that conducting regular audits is highly recommended. This is even more true in case of modifications, such as adding a new device. Of course, these audits must be carried out by qualified specialists who will assess the risk and propose corrective measures.
🌍 Did you know?
The heating of a 2.5 mm2 electrical cable can reach more than 200°C within minutes during a direct short circuit if the protection does not trip. That is more than enough to ignite dust or nearby insulation materials.
Furthermore, regular maintenance is clearly not a luxury. This notably includes the periodic replacement of worn components and checking cable insulation. Again, this is especially true in a company where electrical equipment is numerous and varied.
💬 Personal anecdote: In 2024, I almost experienced a disaster because of a low-quality phone charger left plugged in on a sofa. The casing melted and started scorching the fabric in less than 15 minutes. The lesson is simple: never leave a device charging on a flammable surface and avoid counterfeit accessories without CE marking.
Comparison of protection devices against electrical fires
Before renovating or securing an installation, it is useful to compare the different solutions available on the market. Some directly prevent electrical overloads, others limit the consequences of a fire outbreak.
| Safety Device | Main Role | Advantages | Possible Limitations |
|---|---|---|---|
| Residual Current Circuit Breaker | Cuts the circuit in case of current leakage | Protects people and the home | Requires professional installation |
| Surge Protector | Protects against lightning-induced surges | Ideal in stormy areas | Does not prevent short circuits |
| Power Strips with Built-in Safety | Limits overloads and local surges | Easy to install, affordable | Limited capacity |
| Smoke Detector | Detects smoke early | Legal requirement, effective | Does not warn of electrical fire |
| Domestic Fire Extinguisher (Class C) | Extinguishes fires related to electrical installations | Allows quick intervention | Must be handled with care |
⚠️ Common Misconception
Leaving an electric cable reel partially wound while using a powerful device. The coil effect generates intense heat at the core of the reel which can melt the insulation and cause an induction fire.
Choosing Fire Extinguishers for Electrical Fires
On the market, you will find several types of fire extinguishers that will only be effective if the fire has just started. Once the flames reach a certain height, only the evacuation of all personnel becomes feasible. Here are the main types of extinguishers:
- Powder Extinguishers: they are perfect for smothering flames without conducting electricity. That said, they are less suitable in environments where dust could damage sensitive equipment. We think of computer rooms among others.
- CO2 Extinguishers: these are often considered the best for electrical fires because they do not damage equipment and leave no residue. However, there are risks of asphyxiation, which is why their use is avoided in confined spaces.
- Water Extinguishers with Additives: these extinguishers can be used for electrical fires if applied in spray jets at a safe distance. This is made possible thanks to additives that improve their effectiveness and reduce electrical conductivity.
💡 Practical Tip
For an electrically originated fire, never use water under penalty of electrocution. Only an ABC powder extinguisher or, better yet, a CO2 extinguisher is suitable to smother flames on a device under tension.
Other Innovative Devices to Consider
🌟 Strengths
- Automatic protection 24/7
- Very strict French standards
- Reduction of insurance premiums
🔻 Limitations
- High cost of compliance
- Requires a professional for the panel
The main drawback of traditional fire extinguishers is that they require a human presence to be used. However, it is well known that in many cases, fires break out when no one is on site. On one hand, this is fortunate since there are no victims, but on the other hand, the material damage can be very significant.
In fact, some innovations in fire safety include devices that activate automatically in the presence of flames. This is not a DIY home project, but rather a system with sensors that can detect an abnormal rise in temperature. It should be noted in passing that there are extinguishers that can activate automatically but can also be used manually to take over. A dual protection, in short, which can prove to be very effective!

Frequently Asked Questions
Fuses that regularly blow, burning smells near outlets, or heating cables are alerts that require the immediate intervention of a professional.
Yes, because standards evolve. An installation that is too old may not support modern devices and can pose a risk of short circuit or overheating.
No, it provides a quick alert but does not prevent the problem at its source. Ideally, detectors, standard-compliant circuit breakers, and good practices in the use of electrical devices should be combined.
