It often surprises people when they use a fire extinguisher for just a few seconds, only to realise it’s no longer reliable afterwards. The truth is, most fire extinguishers are not designed for repeated use once activated. Even if there’s still some agent left inside, the pressure that pushes it out drops quickly after discharge. Without that pressure, the extinguisher may not work properly the next time you need it. That’s why experts always recommend refilling or replacing it immediately after use to maintain proper fire protection and avoid taking unnecessary risks.
