Water fire extinguishers are labeled red and have a class A rating. They are effective in fighting fires involving solid combustibles like wood, paper, and textiles. If di-electrically tested, a few models are safe to use on electrical equipment. Water fire extinguishers penetrate burning materials, creating a cooling effect and preventing reignition on class A solid combustible fires (wood, paper, fabrics, coal). Our fire extinguishers are approved, fully charged, and come with a wall bracket. Our water with additive models have superior weight-to-fire rating ratios and are safe to use on live electrical equipment.
