What size fire extinguishers are categorized as hand-portable?

Hand-portable fire extinguishers are specifically defined by their weight, which allows them to be easily carried and operated by an individual. Typically, these extinguishers weigh 5 pounds or less, with the smallest commonly taking up to 2.5 gallons or equivalent. When referring to options, sizes classified under 1 and 2 are most consistent with this definition.

Larger fire extinguishers, such as those categorized as 3 and 4 or sizes 5 and 6, generally exceed the weight and size thresholds for portability, making them less practical for individual use in emergencies. Thus, when determining which sizes are regarded as hand-portable, the assessment focuses on the manageable weights associated with extinguishers categorized as 1 and 2. This ensures that an individual can effectively carry and operate the unit when needed, adhering to safety standards and promoting prompt response to fire incidents.
