                                  Activities in the laboratory usually often use chemicals that smell

                               pungent and emit toxic gases. Although the effect is not direct, but if
                               we inhale it often it will be a problem in the future. That's why we

                               must wear masks when we are in the laboratory.


                                  The function of the laboratory mask is to cover the nose

                               and  mouth  which  can  be  the  entry  point  for  dust  and
                               harmful chemical gases. There are 2 types of masks that we

                               often  encounter  in  laboratories,  namely  medical  masks
                               and laboratory gas masks.

                                  Gloves protect your hands from splashing chemical solutions that
                               can make your skin itchy or blister. The kinds of gloves used in the

                               lab are usually made of natural rubber, nitrile, and neoprene.


                                  The function of gloves in the laboratory is to protect hands from

                               harmful objects and chemicals. These dangerous objects can come
                               from broken glassware, while chemicals can come from concentrated

                               solutions.


                                  Rubber is a material used in the manufacture of laboratory

                               gloves because it is not easy to absorb chemical substances, be it
                               liquid or solid.
