Kidde 21030898 MAR10 Specifications

Designed for Marine & Outdoor Environments

Fire extinguishers installed aboard boats can be exposed to moisture, salt spray and other conditions that accelerate corrosion. The MAR10 is engineered specifically for these environments with a seamless aluminum cylinder and aluminum and stainless-steel operating components.

Kidde states that its current Mariner extinguishers provide 12X more corrosion resistance compared with industry saltwater test standards. This construction makes the MAR10 suitable for marine applications where long-term exposure to water and salt is an important consideration.

What Types of Fires Does the MAR10 Fight?

The Kidde MAR10 uses BC dry chemical agent and carries a 10-B:C UL rating:

• Class B: Flammable liquids and gases such as gasoline, oil and similar fuel hazards.
• Class C: Fires involving energized electrical equipment.

Where Is the Kidde MAR10 Best Used?

• Recreational boats and watercraft
• Fishing boats
• Powerboats and motorized watercraft
• Marine and dockside applications
• Outdoor locations requiring a compact BC-rated extinguisher

10-B:C Rating with U.S. Coast Guard Approval

Although the MAR10 carries a 10-B:C UL rating, Kidde identifies it as meeting the U.S. Coast Guard 5-B requirement for boats and watercraft when installed with the approved strap bracket supplied with the extinguisher.

This gives the MAR10 more Class B extinguishing capacity than a 5-B:C-rated marine extinguisher while retaining a compact 2.5 lb agent size.

12-Year Service-Free Design

The MAR10 is a single-use fire extinguisher with a 12-year service-free design. Kidde notes that under NFPA 10, single-use extinguishers do not require the six-year internal examination required for certain rechargeable extinguishers.

Service-free does not mean inspection-free. Required external inspections and corrective actions still apply. Replace the extinguisher after use or when inspection indicates damage, corrosion, pressure loss or another condition requiring replacement.
