Types of laboratory safety include chemical, biological, radiation, electromechanical and other categories.
Chemical category: experimental places (rooms) involving chemical reactions and chemicals, the main sources of danger are toxic, flammable and explosive, corrosive and other dangerous substances. Management focuses on the safety management of dangerous chemicals, explosives, experimental gases, chemical wastes, etc., which are under key national control, such as highly toxic, easy to manufacture, easy to manufacture explosives, narcotics and psychotropic substances.
Biological: experimental sites (rooms) involving microorganisms and experimental animals, the main source of risk for microorganisms (infectious disease pathogens, etc.), animals and other biological factors that jeopardize the safety of individuals or groups. Management focus is to carry out pathogenic microbial research and experiments must be carried out in the appropriate security level of the experimental premises, to carry out work related to experimental animals must have the appropriate license to use experimental animals must be purchased from the unit with a "laboratory animal production license" and so on.
Radiation: involving radioactive sources, radiation devices and other experimental field (room), the main source of danger for radioactive substances. Management focuses on the use of radioactive sources of qualification, storage places, safety management of personnel involved in radiation.
Electromechanical: mechanical, electrical, high-temperature and high-pressure equipment and instrumentation and other experimental sites (rooms). The main sources of danger for mechanical processing of high-speed equipment, high pressure and high current equipment, laser equipment, heating equipment and cranes, boilers, pressure vessels (including gas cylinders) and other special equipment. Management focuses on high temperature, high pressure, high speed, electromagnetic radiation devices and other special equipment and mechanical, electrical, laser, dust and other safety management.
Other categories: does not involve the above sources of danger in the experimental space (room) for other types of laboratories.
Laboratory common safety knowledge
1, into the laboratory before starting work should be aware of the gas main valve, water valves and electric switch where. When you leave the laboratory, be sure to check the room once, should be water, electricity, gas switch off, doors and windows locked.
2, the use of gas lamps, should be the first match lit, one hand holding a match close to the mouth of the lamp, one hand slowly open the gas door. You can't open the gas door first and then light the match. The size of the flame and the strength of the fire should be adjusted according to the needs of the experiment. When you use fire, you should make sure that the fire is alive, and the fire is out when you leave.
3, the use of electrical equipment (such as ovens, thermostatic baths, centrifuges, electric furnaces, etc.), to prevent electric shock; can never be used with wet hands or in the eyes of the side of the switch switch switch and electrical switches. Should use a test pen to check whether the electrical equipment leakage, where the leakage of the instrument, can not be used.
4, the use of concentrated acid, concentrated alkali, must be extremely careful to prevent spills. With a pipette to measure these reagents, must use a rubber ball, absolutely not sucked by mouth. If accidentally splashed on the laboratory table or the ground, must be promptly scrubbed clean with a wet rag. If it touches the skin, it should be treated immediately.
