Kidde Mariner 110 Marine Fire Extinguisher, 1-A:10-B:C, USCG 5-B Rated, Part 21030899K

The Kidde Mariner 110 is a dry chemical marine fire extinguisher classified 1-A:10-B:C, covering common combustibles as well as flammable liquids and electrical equipment. It carries a USCG 5-B rating and is approved for use aboard marine vessels, making it suitable to satisfy Coast Guard minimum onboard requirements. The extinguisher is built from stainless steel and aluminum for corrosion resistance in the marine environment, and Kidde backs the Mariner 110 with a 12 year service-free life and warranty, so there is no scheduled maintenance or recharge needed during that period.

The unit carries a 2.4 lb agent charge and discharges over 8 to 11 seconds. It is rated for use across a wide temperature range of -40 F to 120 F (-40 C to 49 C) and is tested to 300 psi. A polymer mounting bracket is included for convenient wall storage, using a plastic strap retainer with fold-down straps (Model 322057) that buckles closed to hold the extinguisher securely in place until needed. The extinguisher can also be installed with an optional steel bracket with metal straps (Model 420118) or a simple wall hanger. For reference, USCG minimum requirements call for one 5-B rated extinguisher on boats under 26 feet, two 5-B (or one 20-B) on boats 26-40 feet, and three 5-B (or two 20-B) on boats 40-65 feet.
