Water Fire Extinguishers

Water fire extinguishers are designed to suppress fires in Class A combustibles like wood, cloth, trash and other materials that leave an ash. These types of hazards are often found in office environments and some industrial locations, as well as warehouse and oxidizing chemical storage areas (includes pool chemicals as specified in NFPA 10 Section 5.5.7).
