SnakE 6 Professional – the modular extinguishing system: from EV firefighting to wildfires

SnakE, the modular extinguishing system, is firefighting equipment for alternative-drive vehicle fires and for wildfire fighting.

The SnakE extinguishing system supports fire departments in fighting EV fires. The modular SnakE system is also suited to incident hygiene: it can easily be used as an emergency decon shower or as a vehicle shower.

SnakE can also be deployed as a rotary sprinkler or as a retrofit spray bar for wildfire fighting. One system, multiple proven applications: that makes SnakE a smart addition to any fire department's equipment.

SnakE follows the recommendations of the Tesla Emergency Response Guide: it enables EV firefighting with underbody cooling exactly as recommended there.

The SnakE extinguishing system uses D hoses and combines easily with your existing fire department equipment.

Applications:

EV firefighting, emergency decon shower, gas cylinder cooling

Wildfire fighting, vegetation firefighting, structure protection, dust suppression, preventive fire protection.

The SnakE extinguishing system fits into a 60 × 40 × 12 cm Eurobox, including the optional aluminum frame!

SnakE® underbody cooling

Fighting EV fires

Underbody cooling is the simplest and safest method for efficiently fighting fires in cars with a lithium-ion battery for high-voltage energy storage. Underbody cooling is also recommended in the Tesla rescue data sheets.

Underbody cooling avoids additional damage to the vehicle and carries no risk of unnecessary damage to the battery.

SnakE® keeps the ladder cooled continuously, and temperatures near the ground are generally not as high.

As an alternative, we offer a folding aluminum frame that can also be stowed in the Euro box.

Retrofit spray bar

Our mobile retrofit spray bar is a cost-efficient way to upgrade existing pump-and-roll-capable vehicles. There is no need to wait for the next vehicle procurement.

The wildfire set is an extension of the SnakE® set for EV firefighting and can still be used without restriction for that purpose.

The compact nozzle modules simply clip onto the folding retrofit spray bar and are secured with spring catches. The complete assembly is mounted tool-free on the vehicle's shackles.

In less than 3 minutes, from unpacking to driving off, you can upgrade your fleet with this important tactical capability.

With minimal personnel, firebreaks can be wetted quickly to contain the spread of the wildfire.

  • ⚙️ Modular

    The modularity of SnakE® allows flexible adaptation to different incidents.

    This makes SnakE® versatile for wildfires, EV fires and other scenarios. It also makes retrofitting easier, so existing vehicles can be used more efficiently.

  • 📦 Compact stowage

    SnakE® is the smallest and lightest modular water mist extinguishing system for cooling high-voltage batteries in vehicles. The entire system can be stowed in a single standard Euro box.

  • 💡 Intuitive

    Even as special extinguishing equipment, SnakE® is intuitive to operate and needs hardly any training. This lets crews focus on what matters and always know the right thing
    to do, even under stress.

How does the modular SnakE® system work?

We now explain step by step how to use the SnakE® system.

Coupling D hoses

Connect modules

The individual nozzle modules are connected with specially pre-assembled D (25 mm) hoses. This always ensures an optimal spray pattern, and SnakE® can be extended without difficulty.

Clamping

Mounting nozzle modules

The nozzle modules can be mounted on a specially dimensioned, folding aluminum frame or on a sectional ladder. The overall height is so low that even with burst tires you can still get under most common electric vehicles.

Coupling a C hose

Water supply

Water is supplied via a C (52 mm) connection, which is split into two D outlets after a filter. This always ensures a sufficient water supply and protects the nozzles against clogging. The nozzles can therefore finely atomize the water at all times, increasing the cooling performance with reduced water consumption. Each nozzle uses only around 20 liters per minute.

Simple extension

Spray bar

With a straightforward extension from us, SnakE® can be converted into a spray bar. The same SnakE® set can therefore upgrade any pump-and-roll-capable fire apparatus with a wildfire spray bar. Ideal support for vegetation fires, clearing oil spills from roads or street cleaning.

Fighting fires in EVs with lithium-ion batteries

Which extinguishing agent for EVs?

The extinguishing agent recommended by the professional associations AGBF and vfdb and by the German fire department association is clearly: water.

As when fighting fires in vehicles with combustion engines, it also makes sense to use firefighting foam in some cases.

SnakE® is suitable for plain water as well as for firefighting foam or wetting agent.

What are the challenges of extinguishing EVs with Li-ion batteries?

The high-voltage battery in motor vehicles with alternative drive systems poses an increased risk of electrical accidents. The high-voltage cables are marked in orange and must not be cut under any circumstances.

The battery of an electric vehicle is usually installed in the underbody and is therefore difficult to access, so under normal conditions not much cooling water reaches the battery.

The risk with lithium-ion batteries lies in a so-called thermal runaway, in which many battery cells ignite one another through chain reactions. The damage inside the battery can hardly be located.

In addition, vehicles of modern design generally have a higher fire load and burn with higher energy release and more smoke.

How much water should be used when fighting fires involving high-voltage batteries in vehicles with alternative drive systems?

According to the latest recommendations of the German Social Accident Insurance, the following procedure is recommended for a road traffic accident involving a vehicle with an alternative drive system.

It is advisable to deploy two separate nozzles early on, one for conventional car firefighting and one for cooling the lithium-ion battery (LIB).

In most cases, even a small amount of water is sufficient for efficient cooling.

It is recommended to reach the underbody of the motor vehicle with the high-voltage battery more effectively, in order to increase efficiency and keep extinguishing water consumption as low as possible.

What methods exist so far for fighting fires in motor vehicles with alternative drive systems, e.g. lithium-ion batteries?

  • Wet quarantine/immersion container
  • Extinguishing lance
  • Piercing nozzle
  • Fire blankets
  • SnakE® underbody cooling

What does AGBF Bund recommend for fighting fires in motor vehicles with electric drives?

Following the recommendations of the technical committees for Preventive Fire and Hazard Protection and for Operations, Extinguishing Agents and Environmental Protection of the German fire departments within AGBF Bund, the following procedure was officially recommended in January 2021.

The initial firefighting measures are the same as for a normal car fire: cooling with water and, if necessary, with extinguishing agent additives such as firefighting foam or wetting agent.

It is important to always consult the latest rescue data sheets.

In general, modern vehicles show increased smoke and heat release.

If an electric vehicle is involved, the high-voltage battery should be checked with a thermal imaging camera.

Water remains the efficient extinguishing agent for firefighting.

If a temperature well above the ambient temperature is measured when checking the high-voltage energy storage in the electric vehicle, combined with a steady rise in temperature, current recommendations call for cooling the housing of the high-voltage energy storage with water.

Quarantining is explicitly not a task of the fire department. In its latest technical recommendation, the German Social Accident Insurance (DGUV) advises using this method only in absolutely exceptional cases, as disposing of the extinguishing water places a major logistical burden on fire departments. Preventive wet quarantine in particular must be avoided.

The HV battery in the EV must be cooled and monitored with the thermal imaging camera until the vehicle can be handed over to the operator or a suitable towing service.

Extinguishing success is achieved solely through the cooling effect of the water.
