SENTRY Water Extinguishers

SENTRY Water Extinguishers are designed to extinguish Class A hazards only.   Class A hazards such as wood, cloth, trash, and other materials that leave an ash are often found in office environments and industrial locations, as well as warehouse and oxidizing chemical storage areas.

In section 5.5.7, NFPA-10 mandates the use of water-type extinguishers only in areas containing oxidizers, such as pool chemicals.

With an ample 2.5 gal (9.5 L) capacity, these extinguishers are made to the same standards as the rest of the SENTRY line. Butt-welded stainless steel shell construction assures long service life, while stainless steel, brass, and aluminum alloy components help eliminate corrosion.
