Check electrode expiration to avoid...

While expired electrodes might contribute to skin irritation due to degraded materials, this is not the primary concern associated with electrode expiration. Skin irritation can occur for various reasons unrelated to the expiration date, including allergic reactions or improper application, making this choice less relevant.

A poor lead connection may result from various factors, including improper attachment or damage to the lead wires, rather than the expiration of the electrodes themselves. While expired electrodes can affect performance, the lead connection's integrity is primarily linked to the physical condition of the leads and their attachment, not the age of the electrodes.

Electrocution is a serious risk associated with electrical devices, but it is not directly caused by electrode expiration. Expired electrodes may pose risks associated with inadequate signal quality, but the risk of electrocution is more closely related to equipment malfunction or user error rather than the expiration of the electrodes themselves.
