Explanation:

When someone goes to work in a laboratory or has access to this environment should pay attention to some safety standards to ensure their physical integrity and do not promote any contamination on the site.

In a lab it is important to pay attention to long hair and keep it straight. Loose long hair can come into contact with a chemical, or even catch fire near an open flame.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
