Fire class is the first thing to establish and the listings state it directly. ABC dry powder covers a broad range of fire types. CO2 is used on electrical equipment because it leaves no residue. Foam is rated class AB. An extinguisher outside the class of the fire is the wrong equipment. The class is printed on the body rather than having to be inferred from the colour band.
Charge weight sets how long it discharges rather than how effectively. The range runs 0.6kg and 0.95kg on the disposable units through 1kg, 2kg and 6kg on the ABC rated bodies, and a small extinguisher empties in seconds rather than minutes. Reading the charge weight alongside the class is what tells you whether the unit suits the risk it is placed against.
Disposable and refillable is a decision about what happens after use. A disposable unit is replaced once discharged. A rated refillable unit is serviced and recharged, which is what a workplace requirement usually assumes. A rated body also carries its rating on the label, which a disposable unit does not.
Fire blankets work by smothering rather than discharging, at 1.1 x 1.1m to BS EN 1869, and a vehicle fire safety blanket at 6 x 8m covers an EV rather than a pan. Cabinets and stands mount the equipment where it will be found.
