1, all instruments should be put in the cabinet, except those that are too big to fit in the cabinet, try to put them in the instrument cabinet. If it doesn't fit in the cabinet, it can be placed on the top of the cabinet or on a shelf with a dust cover (such as a transparent plastic bag) and can't be placed on the ground. Generally, musical instruments are large pieces placed below and small pieces placed above; Short pieces, small pieces in front, tall pieces, and large pieces in the back; The heavy part is at the bottom and the light part is at the top; Low-end instruments are at the bottom and high-end instruments are at the top.
2. Instruments are generally laid flat. Many instruments, such as scales and microscopes, cannot be placed upside down or horizontally. Plastic parts, rubber parts, measuring tools, etc. It should be laid flat, not shelved.
3. In general, instruments should not be stacked together. Keep a certain distance between the instruments in the cabinet, and do not overlap or hook. Instruments that are fragile, rolling and easy to scratch, such as thermometers and test tubes, should be stored on shelves, wrapped with soft cloth pads and cotton paper, or placed in other boxes.
4. Avoid direct sunlight. Instruments, such as electronic instruments, should not be placed in direct sunlight. If sunlight can enter the cupboard, it should be blocked by curtains or covers.
5. Keep the storage room clean, dry and ventilated. Rats, cockroaches and termites should be completely eliminated. The instrument cabinet should be dustproof, and the door should be closed and cleaned regularly.
6. Most instruments need moistureproof, especially in rainy season, and some even need moistureproof measures. Moisture-proof agent, such as quicklime, charcoal, calcium chloride, silica gel, etc. It should be put in the cupboard of expensive instruments. Electronic products and audio-visual education equipment should be placed in ventilated and moisture-proof places, usually on the upper floor of cabinets, and be electrified regularly to improve moisture-proof performance. If it is wet, it should be irradiated by an infrared lamp or dried by a hair dryer. It should be completely dry inside before it can be connected to the circuit for formal use.
7. Pay attention to the general protection of the instrument. For example, color TV can't be disturbed by magnetic field, and magnetic objects can't be placed around and at the top; Don't move magnetic objects such as tape recorders, radios and speakers away from the color TV screen, otherwise the magnetic field will magnetize the components of the picture tube, destroy the color purity and cause color distortion or spots. After use, the adhesive tape, spring and transmission belt should be free from tension to avoid elastic fatigue and loss of elasticity.
8. In order to avoid damaging the instrument, such as rust layer, alloy film and aluminum oxide protective layer on the metal surface of the instrument, it should be protected and not wiped. When not in use, it should be coated with a layer of neutral vaseline or wax and wrapped with oil paper. When storing batteries, prevent short circuit or leakage.
9. In order to avoid waste of equipment, pay attention to the sealing of volatile pharmaceutical materials such as alcohol and ether, and seal large bottles of drugs stored for a long time with wax; A small amount of drugs should be packed in a small-necked bottle with a frosted glass cover (reagent bottle glass cover with alkali should be coated with a thin layer of paraffin). When the alcohol lamp is not used, cover it immediately.
10, display and store the instruments, and keep them complete and complete. Similar instruments should be put together, and the mainframe, accessories, spare parts and spare parts of combined teaching AIDS of the same instrument should be recovered and restored in time after use, and stored in boxes (boxes) to prevent loss.
Generally speaking, the chemistry laboratory has three characteristics:
1, there are many sundries. There are glassware, bottles and jars, and bits and pieces; Glass conduits vary in length and are fragile and easily broken. Instruments and supplies vary in size, from ovens and scales to nails and wires. There are still some things that look unremarkable, but it is necessary to do some experiments, such as: glass, broken porcelain, rags, cotton, cotton thread, wool, mud, sand, stones, wood blocks, wood strips and so on.
2. There are many medicines. Toxic and harmful, flammable and explosive, volatile, liquid, solid, organic, inorganic, and hundreds of pharmaceutical reagents. And the performance is different, some can't be exposed to the air, and they will catch fire when they meet the air, so they should be kept in water. Others can't be touched with water, and they will be kept in kerosene in case of aquatic fire.
3. Use more water. Most chemical reactions are carried out in solution and cannot be separated from water. Most pharmaceutical reagents also need water, and a large number of glass instruments can't be cleaned without water. Based on the above-mentioned "three-multi" characteristics, the chemical laboratory is managed by districts and levels. ?
Instrument room: this room stores all kinds of chemical detection instruments except drugs: various precision instruments such as balances, acidity meters and centrifuges, as well as various glass instruments such as test tubes, beakers, measuring cylinders and droppers. ?
Medicine room: What the chemistry room fears most is that the medicines are piled up in a mess. Disorderly stacking of drugs, expired drugs and damaged labels are all potential safety hazards. According to the different properties of pharmaceutical reagents, they should be classified and stored in appropriate locations. Inorganic and organic are separated, oxidant and reductant are separated, and toxic and harmful flammable and explosive are separated. Each cabinet takes corresponding safety measures according to the nature of different drugs. At the same time, do a good job in drug use registration.
