Safety Measures in Chemistry Laboratory and in Use of Chemicals
The place where scientific experiments are held is called the laboratory. Similarly, the place where experiments of chemistry are held is called the Chemistry laboratory. It is understood, there will be various chemicals in a chemistry laboratory.
Almost all chemicals are prone to explosion, some are flammable, some harm our bodies directly and some are dangerous for nature. Most of the apparatus in a chemistry laboratory is made of glass. Therefore, we need to be cautious from the moment of entry into the laboratory to the moment we come out.
Lack of caution may result in accidents, e.g. if acid falls on your body, you will get injured; if acid falls on your dress, the dress will be spoiled. Besides, there may be accidents including fire or explosion in a laboratory. Therefore, you need to wear an apron. The apron will be knee-long and the sleeves will be up to your wrist. Its color will be white. You will use hand gloves and safety goggles on your eyes. Some of these safety measures are given in the following picture:
We need to learn the nature of a chemical before we start to use it. We need to know whether that is flammable or radioactive. These are made clear using some signs on the containers. To introduce a globally harmonized system about this, the United Nations organized a conference named Environment and Development. This conference gave a set of harmonized signs for different risky substances identifying risk, the extent of risk, and precautions.
