Lithium-ion (Li-ion) batteries are used in many devices now found in our homes and workplaces. Laptops, mobile phones, cameras, e-scooters, power tools and electric cars are all powered by rechargeable lithium-ion batteries. Whilst the chances of a lithium-ion battery fire are relatively low, the prevalence of these batteries and the ferocity with which they burn presents a new fire risk that is difficult to tackle with traditional methods. So, can you extinguish lithium-ion battery fires if they occur? We look at what fire safety technology is available to tackle them.
Lithium-ion Fire Extinguisher
There are 2 types of fire extinguisher to tackle lithium-ion battery fires that occur in items such as mobile phones, laptops and power tools.
The Lithco LB6 Fire Extinguisher is a water-based extinguisher with an additive called ‘P Foam’. The agent in these extinguishers is specially designed to penetrate through the outer casing of electrical devices to the source of the fire (the battery). The Lithco LB6 has been rigorously tested and is proven to be very effective when fighting li-ion battery fires. The Lithco LB6 is suitable for use on live electrical equipment (up to 1000v). It also effectively extinguishes class A fires making it a versatile unit.
The other type of lithium-ion fire extinguisher uses an Aqueous Vermiculite Dispersion (AVD) agent to surround and cut off the burning battery cells.
Designed specifically for use on rechargeable lithium-ion battery fires, the LB6 fire extinguisher satisfies modern fire risks in a cost-effective, multi-purpose solution.
- Designed for UPS systems, laptops, power tools, and bulk device chargers
- Heat dispersing, low-viscosity agent to penetrate battery casings
- Rigid applicator lance for enhanced control and user safety
- Third-party tested up to 360Wh battery capacity
Electric Car Fire Blanket
Due to the intense nature of electric car fires and the toxic fumes emitted, they are notoriously difficult to tackle. The Electric Car Fire Blanket from Bridgehill is designed to contain the fire to prevent flames and flying materials from spreading to nearby vehicles and buildings. As well as containing the fire, the fire blanket stops oxygen from getting to the fire, therefore controlling it further. Designed for use by the fire service or in parking lots, at charging stations or on car ferries, we recommend this car fire blanket is used by trained personnel only.
Lithium-ion Battery Safe
The Phoenix Battery Commander range provides safe storage and a protected charging point for li-ion batteries and devices. Heat activated seals contain any fire within the safe and also protect the safe contents from an external fire. For further protection, an optional fire extinguisher, smoke detector or alarm can be fitted.
Extinguishing Lithium-ion Battery Fires
The lithium-ion extinguishers and containment featured in this blog provide some solutions to this modern fire risk. Great care must always be taken when tackling lithium-ion battery fires as lithium-ion burns quickly and intensely and emits toxic fumes. If in any doubt, always contact the fire service as soon as possible to deal with the blaze and evacuate the area.
FAQs
What can lithium-ion extinguishers be used for?
Lithium-ion extinguishers can be used to tackle fires in any item that is powered by a lithium-ion battery. This includes rechargeable devices such as mobile phones and laptops, power tools or electric bikes or e-scooters amongst others. Lithium-ion fire extinguishers are not suitable for use on electric cars. This is because of the large quantity of extinguishing agent that would be required to tackle such large fires. Instead, an electric car fire blanket could be used to control and contain the fire.
What fire extinguisher should be used for lithium-ion batteries?
There are two types of fire extinguisher that have been specifically developed for putting out lithium-ion battery fires. The Lithco LB6 Fire Extinguisher will effectively extinguish a lithium-ion battery fire in handheld devices, laptops and power tools plus other lithium-ion battery powered items. A car fire blanket will contain and control a lithium-ion battery fire in an electric or hybrid vehicle.
