What is the weight of a portable CO2 fire extinguisher?

The typical weight of a portable CO2 fire extinguisher commonly used in aviation and other industries is indeed around 15 pounds. This weight is appropriate because it allows for manageable handling while ensuring that the extinguisher contains enough CO2 to effectively suppress small to medium-sized fires.

CO2 extinguishers are advantageous for use in environments where electronic equipment is present, as they do not leave any residue that can damage sensitive devices. The 15-pound model is a standard size that balances capacity and ease of use, making it a popular choice for various settings.

The other weights listed, like 10 pounds or 20 pounds, represent different types of extinguishers or sizes that may not be as commonly utilized in portable scenarios or might not meet the specific requirements for aviation environments.
