In AEDs, the seal color is a quick readiness check. A green seal means the device has passed its checks—battery level is sufficient, pads are usable, and the unit is ready for use in an emergency. If the seal is green, you can proceed with confidence.

Red typically indicates not ready, often due to expired pads or a depleted battery. Yellow usually signals that service or maintenance is needed. Blue isn’t a standard readiness indicator for AEDs. If the seal isn’t green, don’t rely on the device and arrange for replacement or service.
