Please find the answer in the explanation
Explanation:
In Engineering, safety is very essential and very important for all engineers to stick to.
A.) Wearing metal ring or bracelets.
When their is discharg of electrical charges, wearing of metal rings or braceletsb can allow charges to pass through them into the body which can eventually lead to electrical shock.
B.) Being barefoot
Being bare footed is very dangerous because someone can mistakenly step on naked wire which can lead to electrical shock.
C. Working on a damp concrete floor.
It is very hazardous to be working on a damp concrete floor because of the water moisture. It is very unsafe for any electrical job to be done on any wet area because water can conduct electricity which can lead to electrical shock.
d. Touching grounded conductors while working on electrical equipment
Grounded conductor can allow charges to flow through them. So, it is very unsafe to have them have contact with the body because of electrical charges.
e. Working on electrical equipment with sweaty hands
A sweaty hands contain some content of water which can conduct electricity and lead to electrical shock.

What is topographical survey?
A topographical survey, often known as a land survey or topographical land survey, is a type of survey that includes contours. Topographical land surveying determines the exact location and specifications of natural and man-made features on a piece of land. The survey is then turned into a suitable and thorough plan, which incorporates man-made characteristics such as boundaries, neighbouring buildings, sidewalks, and so on. Natural elements such as trees, ponds, and ground contours are also detected by the topographical survey. Having a clear and accurate map of your property might help you avoid costly downstream mistakes caused by unforeseen challenges. It can supply you with the information you need about the land before making any alterations to it.
