What personal protective equipment should be worn in the laboratory?
(1) in the laboratory, in order to prevent hand injuries, you can choose to wear all kinds of gloves as needed. Gloves should be worn when exposed to corrosive substances, edges, sharp objects (e.g., broken glass, wood, metal fragments), overheating or supercooling.(2) gloves must be used with care to ensure no breakage.
(1) full protective spectacles (eyes and face) are the most vulnerable parts of the laboratory, and therefore their protection is particularly important. In laboratory, neon test personnel must wear safety goggles(2) when chemicals are splashed into the eyes, rinse thoroughly with water immediately. When washing, the eyelid should be opened, carefully rinse with tap water for a few minutes, then distilled water, and then go to the clinic for treatment.(3) facial guards are used to protect the face and throat. To protect against possible explosions and harmful gases from experiments, wear plexiglass protective masks or respiratory protective appliances.
(a) polyethylene disposable gloves: used for treating corrosive solid medicines and dilute acids (e.g., dilute nitric acid). But the gloves can not be used for treatment of organic solvent, because many solvent can penetrate polyethylene, and holes in the seam.(b) medical latex gloves: this kind of gloves is made of latex and can be reused after treatment. Since this glove is short, protect your arm. The gloves are not suitable for processing hydrocarbon solvents (such as hexane, toluene) and chlorinated solvents (such as chloroform), because these solvents will cause swelling and damage the gloves.
