Overview
The First Alert Marine1 is a UL rated 1-A:10-B:C multipurpose fire extinguisher with all-metal construction built for boats and other marine environments. It uses a monoammonium phosphate agent and ships with a mounting bracket and strap.
Its 1-A:10-B:C rating covers ordinary combustibles such as wood and paper alongside flammable liquid and electrical fires, broader coverage than the smaller B:C-only units sold for jet skis. It is US Coast Guard approved when mounted with the included bracket, and the all-metal valve and trigger are built for the vibration and moisture of a boat rather than a household closet.
- UL rated 1-A:10-B:C multipurpose coverage
- All-metal valve, trigger, and construction
- Mounting bracket and strap included
- US Coast Guard approved when bracket-mounted
Who it's for
Boat owners who need a Coast Guard approved extinguisher covering wood, paper, liquid, and electrical fires aboard. Not the right pick for a jet ski or PWC, where a smaller B:C rated unit is the usual requirement.
Pros and cons
- 1-A:10-B:C rating covers wood and paper, not just liquids
- All-metal valve and trigger for marine durability
- Mounting bracket and strap included
- Coast Guard approved when bracket-mounted
- Heavier and larger than a PWC-sized unit
- Requires professional recharge after use, not a simple refill
- No stated discharge time or range figure
Performance notes
The extinguisher discharges a monoammonium phosphate dry chemical that smothers a fire and interrupts the reaction feeding it, effective across the wood and paper, liquid, and electrical classes on its rating. The metal gauge shows charge state at a glance, and once discharged the unit is meant to be recharged by a certified professional rather than replaced outright.
