Water fire extinguishers are the most common extinguishers in the UK. Ideal for use in offices, schools, shops, etc. they can tackle class A (solid combustible) fires without leaving any toxic or chemical residue. Unlike most other plain water extinguishers, the UltraFire 6ltr water unit has passed the 35kV dielectrical conductivity test, minimising the risk to the user when the extinguisher is discharged on live electrical equipment.
