What is the typical body resistance of a qualified worker in ohms?

The typical body resistance of a qualified worker is generally considered to be around 1,000 ohms. This value is established based on a number of factors, including the average skin resistance of a healthy adult and the conditions under which electrical work is performed. Skin resistance can vary due to factors such as moisture, pressure, and the condition of the skin, but for safety and standard calculations in electrical work, 1,000 ohms is often used as a conventional reference.

This value is important in electrical safety and risk assessments because it helps in determining the potential current flow through a person if they come into contact with an electrical source. Lower body resistance can lead to higher current flow, increasing the risk of electrical shock. Thus, understanding the typical resistance is crucial for qualified workers to follow safety protocols effectively when working near energized circuits or equipment.
