Kidde 21030899 MAR110 Mariner 110 ABC Marine Fire Extinguisher

The Kidde 21030899 MAR110 Mariner 110 is a compact multipurpose marine fire extinguisher designed for common fire hazards found aboard boats and watercraft. It contains 2.5 lb of ABC dry chemical agent and carries a 1-A:10-B:C UL rating for Class A, B and C fires.

Kidde 21030899 MAR110 Specifications

Compact ABC Protection for Marine Fire Hazards

The MAR110's 1-A:10-B:C rating provides protection across the three common fire classes encountered on boats and watercraft:

• Class A: Ordinary combustibles such as fiberglass-reinforced plastic, wood, cloth, paper and rubber.
• Class B: Flammable liquids and gases, including common fuel-related hazards.
• Class C: Fires involving energized electrical equipment.

This makes the MAR110 particularly useful when you want a compact extinguisher that adds Class A protection without moving to a larger 4 lb ABC model.

MAR110 vs. BC-Only Marine Extinguishers

Although both types can protect against flammable-liquid and energized-electrical hazards, the MAR110's multipurpose ABC agent adds a Class A rating for ordinary combustible materials.

That distinction can be important aboard vessels containing combustible materials such as wood, paper, cloth, rubber or fiberglass-reinforced plastic. The appropriate extinguisher should always be selected according to the hazards present and applicable marine requirements.

Built for Salt, Water & Outdoor Exposure

Marine fire extinguishers may be exposed to moisture, salt spray and other conditions that can accelerate corrosion. The current Kidde Mariner series uses aluminum and stainless-steel components designed specifically for marine and outdoor environments.

Kidde states that the Mariner design provides 12X more corrosion resistance compared with industry saltwater test standards, helping improve durability in demanding marine conditions.

Where Is the Kidde MAR110 Best Used?

• Recreational boats and watercraft
• Powerboats and motorized watercraft
• Fishing boats
• Cabin boats with ordinary combustible materials
• Marine and dockside environments
• Outdoor applications requiring compact multipurpose ABC protection

Is the MAR110 Right for Your Boat?

The MAR110 is a strong option when you want ABC protection in a compact 2.5 lb agent size. Its 1-A rating expands protection beyond fuel and electrical hazards to include ordinary combustible materials commonly found aboard many boats.

For applications requiring greater Class A firefighting capability, longer discharge range or additional agent capacity, a larger Mariner ABC model such as the MAR210 may be more appropriate.

12-Year Service-Free Design

The MAR110 is a single-use extinguisher with a 12-year service-free design. Under NFPA 10, single-use extinguishers do not require the six-year internal examination applicable to certain rechargeable extinguishers.

Annual external examinations and appropriate corrective actions are still required. Replace the extinguisher after discharge or when its condition indicates that replacement is necessary.
