Fire Extinguishers & Equipment FAQs
Are water mist extinguishers safe for use around electrical equipment?
Yes,
de-ionised water mist fire extinguishers have
passed the di-electrical conductivity test, which marks them as safe for use on live electrical equipment up to 1,000V. Two key factors differentiate water mist fire extinguishers from traditional water or foam units:
- Water mist extinguishers are filled with de-ionised water, which cannot carry electrical current.
- The microscopic droplets that form the signature mist are too small and too far apart for electricity to flow through them.
