Why is it considered unsafe to pull on a cord to remove a plug?

Pulling on a cord to remove a plug is considered unsafe primarily because it can damage the cord itself. This type of action puts undue stress on the wiring within the cord, which can lead to fraying, exposed wires, or other forms of physical damage. Consequently, this can compromise the cord's insulation or even break the internal wires, leading to an increased risk of electrical hazards such as shocks or short circuits.

In addition to the potential damage to the cord, improper unplugging techniques can also create risks for the electrical outlet and the connected device over time, by introducing wear and tear on those components as well. Prioritizing the proper method of ejecting a plug, which involves grasping the plug body rather than tugging on the cord, not only preserves the integrity of the cord but also enhances overall safety in a healthcare setting.
