As an important base for scientific research and personnel training, the laboratory is in crisis and has frequent accidents. This is especially true in chemical laboratories, which use a variety of hazardous chemicals and various types of electrical equipment, and often involve high temperature, high pressure, vacuum, radiation, magnetic fields, strong (excited) light and other risk factors, coupled with the narrow use of laboratory per capita, The long-term work of the experimenter is prone to fatigue, and many safety hazards make the chemical laboratory safety problem not to be ignored, especially before the holiday.
Laboratory safety, we need to focus on these major categories
Laboratory fire safety, laboratory chemical safety, laboratory biosafety, laboratory radiation safety, large instrument and equipment safety, experimental technology safety, laboratory network security, please take a closer look. . .
Laboratory fire safety
1. A certain amount of fire-fighting equipment must be stored in the laboratory. The fire-fighting equipment must be placed in an obvious location for easy access. The designated personnel should be managed. All personnel should take care of the fire-fighting equipment and regularly check and replace them as required.
2. All flammable and explosive materials (such as hydrogen, nitrogen, oxygen, etc.) stored in the laboratory must be kept at a certain distance from the fire source and power source, and should not be stacked at will. Fireworks are strictly prohibited in laboratories that use and store flammable or explosive materials.
3. Do not arbitrarily pull the wires, do not overload the power, there must be no exposed wire ends in the laboratory, it is forbidden to replace the fuse with wire; no items should be stacked in the power switch box.
4. Electrical equipment and wiring, plugs and sockets should be inspected frequently, and kept in good condition. If it is found that sparks, short circuit, heat and insulation damage, aging, etc., the electrician must be notified to repair. Electric heaters, electric ovens and other equipment should be disconnected.
5. Use a soldering iron, place it on a non-combustible and heat-insulated bracket, and do not stack combustible materials around it. Immediately after use, remove the power plug.
6. The flammable gas cylinders and the combustion-supporting gas cylinders shall not be mixed. All kinds of cylinders shall not be close to heat sources and open flames. Sun protection measures shall be taken, collision and knocking shall be prohibited, and the paint marks shall be kept intact. The flammable gas cylinders used should generally be placed in a cool outdoor place where air is circulated. Use pipes to enter the room. Hydrogen, oxygen and acetylene should not be mixed in one place. Keep a distance of more than 10m from the source of fire. All cylinders must be secured with a fixture to prevent dumping
7. In the laboratory without approval and filing, high-power electrical equipment should not be used to avoid exceeding the power load.
8. It is strictly forbidden to stack items on the corridor inside the building to ensure the smooth flow of fire.
Laboratory chemical safety
1. Chemicals used in various types of laboratories must be purchased by the school in a unified manner, and no laboratory or individual may purchase them privately. The purchase of highly toxic and precursor-producing drugs requires the permission of the public security department and can be purchased with a license.
2. Chemicals should be stored separately, and the interacting drugs should not be mixed and must be stored separately. All medicines must be clearly labeled and the storage rooms and cabinets must be kept clean and tidy. Medicines with special properties must be stored according to their characteristics. Unnamed and expired drugs should be cleaned and destroyed in time. Do not store highly toxic drugs in the laboratory.
3. Hazardous chemical containers should have a clear identification or label. Hazardous chemicals that are exposed to fire, moisture, fire, explosion, or toxic gases shall not be stored in open air, wet, leaky or low-lying areas where water is easily accumulated; hazardous chemicals that are easily burned, easily explosive, or produce toxic gases when exposed to sunlight. Drugs should be stored in a cool, well-ventilated location. A prominent safety sign should be placed in the storage area of hazardous chemicals.
4. Poisonous items must be stored in the special drug library of the school. The warehouse must meet the relevant safety requirements, and must be kept in a “double double lock”. The use of highly toxic items must be approved by the School Security Office. The minimum amount should be collected according to the usage. The “double” should be used for “double” use. At the same time, the registration and consumption records should be used and must be strictly in accordance with the regulations. , to achieve “double lock” safekeeping.
5. Personnel engaged in hazardous chemical testing should receive appropriate safety technical training, be familiar with the nature of the drugs used, and be proficient in the operation methods of the corresponding drugs. In particular, the use of dangerous chemicals that are flammable, explosive, highly toxic, pathogenic, and stress-responsive, etc., are strictly prohibited. Blind operations are strictly prohibited. Relevant operational procedures must be followed, and the corresponding regulations of the state and industry are Standard, strictly enforced.
6. The waste liquid from the laboratory shall not be discarded at will, and it shall be discharged into the ground, underground pipeline and any water source to prevent pollution. The experimental waste liquid waste shall take appropriate measures to be treated as “harmless”. The laboratories that cannot be disposed of shall not be discharged and treated privately. The laboratory shall use special containers to classify and store them to prevent secondary pollution caused by leakage and loss.
7. Each laboratory will transport all kinds of waste liquids and wastes collected to the waste recycling warehouse under the laboratory equipment management office, and the equipment management office of the real room will contact the department with processing qualification designated by the Environmental Protection Bureau for unified disposal.
