See the related link for more information. Also refer to NFPA-10 for more specific details.
How many fire extinguishers are required aboard an 18-foot powerboat with installed fuel tank?
At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat, unless it is under the following exception:
- "motorboats less than 26 feet in length,
- propelled by outboard motors and
- not carrying passengers for hire, need not carry such portable fire extinguishers if
- the construction of such motorboats will not permit the entrapment of explosive or flammable gases or vapors" [bullets added]
A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).

What does a Co2 fire extinguisher remove?
In a carbon dioxide extinguisher, the carbon dioxide is kept in pressurized liquid form in the cylinder. When the container is opened, the carbon dioxide expands to form a gas in the atmosphere. Carbon dioxide gas is heavier than oxygen, so it creates a blanket around the burning fuel and displaces the oxygen surrounding the fuel.
Or to simplify, it removes oxygen from the fire triangle, to smother it and extinguish it.
You also can take out one of the elements by using a wet sack or just a plain blanket

Which fire extinguisher is used for grease fire?
The National Fire Prevention Association (NFPA), British Standards Institute (BSI) and European Normal (EN3) have developed and defined oil or grease fires as classification "K" (in the USA) and "F" (Europe) independent of the general class B category. This was born out of the recognition that cooking oils and grease (cooking media) produce extremely difficult fires to extinguish due to their high auto-ignition temperature and fast temperature acceleration. additionally, these hydrocarbon fuels have an inherent explosive reaction when water is applied as an extinguishing agent. Therefore, only a K-Rated extinguisher should be used to extinguish a cooking oil or grease fire in a residential kitchen or a restaurant.
Until now, K-Rated units were exclusively available in 6-Liter and 2½-gallon extinguishers with an average cost of between $150 to $350, and are cumbersome for individuals to use both on residential and commercial "K" fire applications. In the advent of the new FireStopper® Technology and Products the residential and commercial user can now acquire small (from approximately 7½- inches tall to 11½-inches tall K-rated and Listed, all fire class (A-B-C-D-K) effective and affordable extinguishers. This new class of extinguishers are "Green" Non-Toxic and Non-Irritant, liquid extinguisher are the quintessential industry changing products for the new millennium.
A soda water extinguisher can be used on a fire of paper. Or use a carbon dioxide extinguisher if you don't want water damage, or if there is anything electrical that can cause a shock. Use foam on oils and flammable liquids.
