Lithium fire extinguishers - advice, installation & maintenance

The CWS lithium fire extinguisher is able to quickly and reliably extinguish fires of fire classes A and D.

  • Fire class A: Fires of fire class A contain solid, mainly organic substances (e.g. wood, paper, textiles)
  • Fire class B: Dire class D with metals

The fire extinguisher is especially suitable for fires involving lithium, one of the most widely used materials for batteries and accumulators. Lithium is an invisible component in every company and household with a fire hazard that should not be underestimated, especially in the event of damage, thermal loads (e.g. overheating) or deep discharge. As a result, the special extinguisher is mostly used in craft and industrial companies as well as in battery rooms or public buildings that have many battery-based devices in use.

The fire extinguisher contains an aqueous solution with fine natural silicon crystals (minerals). These evaporate, swell and merge into a tight barrier during the extinguishing process. This isolates the fire and reduces the fire temperature to below 100 ° C. It is suitable for an outside temperature of +5 ° C to +60 ° C and can also be used on electrical systems up to 1,000 volts (minimum distance 1 m). In order to guarantee maximum safety, all our foam fire extinguishers are officially tested and approved (DIN EN 3, GS, and CE). The fire extinguisher is available as a portable rechargeable fire extinguisher, which is supplied with a wall bracket or a floor stand.

Please note: According to DIN 14 406, fire extinguishers in commercial and public facilities must be serviced at least every two years by an expert such as CWS Fire Safety. Use the digital fire protection file from CWS Fire Safety to see which fire extinguishers you have and when the next maintenance is due. CWS supplies, installs, and maintains foam extinguishers for your safety.
