It's not a universal rule or anything, but some electricians only need 1 hand for reconnecting wiring or what-not. So keeping the other hand behind your back keeps you from placing it on static sensitive equipment or electrical circuits.
===========================
The reason is much more substantive. It is this:
You don't get shocked by touching an electrically-live point, no matter how high
its voltage may be. Birds sit on bare multi-kilovolt lines every day without harm.
You're harmed only if current passes through part of your body. In order for that to happen,
you must be touching two places that have a voltage difference between them.
So the best way to avoid most dangerous situations is: Wear shoes with thick
rubber soles, and keep one hand away from anything that conducts electricity.
This makes it pretty difficult to get into a situation where current can flow into
you at one place and out of you at another place.
The experienced electrician is constantly aware that he has two big efficient
electrodes hanging from his shoulders. To avoid setting up a conducting path
through his body, he keeps one electrode behind his back, or in his pocket.

What is electrical layout diagram is?
An electrical layout diagram is a detailed plan that shows the arrangement and connection of electrical components in a building or facility. It includes information on the location of outlets, switches, lights, and other electrical devices, as well as the routing of wiring and cables. This diagram is essential for guiding electricians during installation and maintenance work.
Is temperature a measure of work?
No, temperature is not a measure of work, because work is the form of you doing something to an object to move it through an empty space. You are not doing anything to temperature, so therefor no, it is not work.
Do geologist work inside or outside?
Geologists can work either inside or outside, depending on their specific job tasks. Field geologists often work outdoors, conducting fieldwork such as collecting rock samples, mapping geological formations, and studying landscapes. On the other hand, geologists who focus on data analysis, research, or teaching may work primarily indoors in offices, laboratories, or classrooms.
How is weathering and erosion are related?
Weathering is the process that breaks down rocks into smaller pieces, while erosion is the transportation of those smaller pieces to a different location. Weathering weakens the rocks, making them more susceptible to erosion by water, wind, or ice. Together, weathering and erosion work hand in hand to reshape the Earth's surface over time.
What is the driving force behind erosiontransportation deposition and lithification?
The driving force behind erosion, transportation, deposition, and lithification is mainly gravity and water. Gravity causes rocks and sediment to move downhill, while water acts as a powerful force in eroding, transporting, and depositing material. Over time, these processes work together to shape the Earth's surface and create sedimentary rocks through lithification.

What is the level of education for electricians?
they must be smart because they need to know how work with lights and mechanics
What kind of electricians are there?
There are several types of electricians, usually defined by the location that the electrical work is being done. For example a residential electrician works on houses/apartments. A commercial electrician works in commercial buildings, usually any building that is open to the public. An industrial electrician works in factory's or large production facilities. They are the three most common types of electricians but there are specialized areas also that do a specific task. Lineman electricians work on the transmission lines that connect power from the generating location to the consumer. Im sure i have left out some of the other specialized electricians but those are the major electrical fields.
