The essential idea is that extinguishers are labeled with the kinds of fires they can handle. For electrical fires, the label must indicate Class C or say it’s suitable for electrical fires. That marking shows the extinguisher is rated for use on energized electrical equipment, helping you choose a device that won’t create a new hazard when used around live circuits. In practice, you want a label that confirms Class C compatibility so you know the extinguisher is designed for electrical fire scenarios. The other details mentioned—like a gauge in the green zone or brand logos or discount codes—do not communicate anything about fire-type suitability, so they don’t help you determine if the extinguisher is appropriate for electrical fires.
