Why do electricians keep one hand in their pocket, electricians keep one hand in pocket as safety technique when working on live electrical circuits to prevent current from passing through heart and causing fatal shock, by keeping one hand in pocket they avoid creating path for current to go from one hand through chest to other hand and through heart. Electrical safety rule is to work with one hand when possible near live circuits, as current entering one hand and exiting other hand passes through chest and heart, which can cause cardiac arrest, while keeping one hand in pocket ensures current if it flows will go through one hand to feet rather than across heart, reducing risk of fatal heart disruption, though still dangerous. This is old school safety trick taught to electricians to minimize risk when troubleshooting live panels, with idea to keep one hand away from circuit to avoid completing circuit across chest, with other safety practices including wearing insulated gloves, using insulated tools, and de-energizing circuit when possible. So why do electricians keep one hand in pocket, to prevent current passing through heart by avoiding two handed contact with live circuit, reducing risk of fatal shock, with technique being safety habit to work one handed near live electricity.
