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).

With an ample 2.5 gal (9.5 L) capacity, these extinguishers are made to the same high standards as the rest of the SENTRY fire extinguisher line. Clean, durable, butt-welded stainless steel shell construction leads to long service life, while stainless steel, brass and aluminum alloy components help eliminate corrosion. Additional features include simple squeeze-grip operation and easy recharge and maintenance in the field using standard air valve for pressurization. The extinguisher operating temperature range is 40 °F to 120 °F (42 °C to 49 °C).

The SENTRY Stainless Steel Water Fire Extinguisher can be utilized in many Class A hazards such as office environments and industrial locations, as well as warehouse and oxidizing chemical storage areas. The unit features a stainless steel shell and stainless steel valve. The trilingual nameplate features easy to read step-by-step instructions for operating the extinguisher in English, French, and Spanish. The Schrader valve allows for easy recharge in the field. Use of fresh, clean water is recommended.
