We have to handle laboratory procedures very carefully because the chemicals are not good for health and can cause serious diseases in humans and can damaged the skin very badly so we can conclude that the open end of the test tube should be placed away from the people.

The meter, gram, and liter are the three most common base units in the metric system.
This name is derived from the Greek word metron, which means "measure."
The physical standard for the meter was to be built to equal one ten-millionth of the distance between the North Pole and the Equator along the meridian running between Dunkirk, France, and Barcelona, Spain.
The kilogram, kilometer, and kilocalorie all share the property of being 1000 times larger than a base unit in the metric system.
