Detailed explanation-1: -Storing food or beverages in chemical cabinets/refrigerators facilitate chemical absorption by vapor. Thus, chemical exposure takes place upon consuming food or beverages stored with chemicals. Therefore, eating or drinking in the lab is strictly forbidden.
Detailed explanation-2: -Loose fitting clothes, easily combustible clothes, and long, unrestrained hair are all fire and accident hazards, and are not appropriate in the laboratory. Since hearing is important for learning and to avoid accidents, radios, tape, or CD players may not be used in the lab.
Detailed explanation-3: -Do not eat, drink, chew gum, smoke or apply cosmetics in the lab. Do not put pieces of lab equipment in your mouth. Do not work with chemicals until you are sure of their safe handling. Do not use the phone or computer with gloves on your hands.
