During the postponement of the resumption of work, the equipment will be powered off for a long time and will be easily affected by seasonal climate changes, environmental temperature and humidity changes. The maintenance and maintenance of the equipment are related to the integrity, utilization and experimentation of the equipment. Therefore, if the instrument is not fully inspected in advance, it may cause the instrument to fail to turn on normally or produce abnormal noise, and even cause loss of the instrument.
How to disinfect in the testing laboratory?
Commonly used are soaking, wiping, spraying, and fumigation. Different objects and places require different disinfection methods.
Small objects (such as gloves, fabrics) can be immersed and disinfected with chlorine-containing disinfectants (pay attention to the time and concentration); doorknobs, light switches, telephones, office desks, chair backs and other contact people are recommended to use wiping method to disinfect (500 Wipe with a chlorine-containing disinfectant at milligrams per liter); spraying is recommended for large-area surfaces such as walls and floors.
How to disinfect the air in the testing laboratory?
The preferred method of air disinfection is natural ventilation. Natural ventilation can reduce the possible content of indoor viruses, diluting its concentration to reduce the risk of disease.
What are the precautions for disinfection in the testing laboratory?
Personal protection is very important when disinfecting the testing laboratory. Pathogenic microorganisms pose a potential risk of harm to the human body, and the disinfectant itself is also harmful to the human body. Therefore, when doing disinfection work, personal protection must be done (such as: wearing a mask, eye mask, hat, wearing a disposable poncho, etc.). At the same time, it should be noted that the action time of the chlorine-containing agent is 15 to 30 minutes, and the follow-up should be wiped with clean water.
After completing the disinfection treatment and resuming work, we should also do a good job in the maintenance and maintenance of the equipment to ensure the integrity of the equipment, the utilization rate and the success rate of experimental teaching.
1. For the instruments that are not turned off in the laboratory, they can be turned on after confirming that the environmental conditions and other requirements meet the power-on conditions. If necessary, perform maintenance first. Start-up should be carried out by authorized personnel. It is advisable to check the status of the instrument after starting up and record the status of the device. Equipment that requires periodic inspection can be arranged for periodic inspection after a long period of shutdown.
2. Small and medium-sized equipment can be turned on to preheat, drive moisture, and check equipment status.
3. For equipment that does not require verification/calibration, the equipment status can be confirmed at this time and the equipment identification can be replaced.
4. Dust removal and cleaning are also the highlight of instrument maintenance. Once the instrument absorbs dust and dirt, it will not only affect the performance of the instrument, shorten the service life, and directly affect the experimental results.
Instrument dust removal TIPS:
Dust enters almost everywhere. There is dust on electrical appliances. In severe cases, it will cause short circuit and leakage. There will be dust on precious precision instruments. In severe cases, the instrument will be scrapped.
There are many ways to remove dust, which mainly depend on the condition of the dust attached to the surface and the degree of dust attachment. In dry air, if there is little dust or the dust has not been damp and formed into spots, you can wipe it with a dry cloth, wipe with a towel, brush with a soft brush, etc. to remove the dust on the general instrument; for the dust inside the instrument, use leather Chi, ear-washing ball type inflator blows air to remove dust, you can also use a vacuum cleaner to collect dust; the dust in the diagonal and the seam can be combined with the above methods to remove dust.
However, for precious precision instruments, such as optical instruments, meter heads, etc., dust removal by the above method will also damage the instrument. At this time, special dust removal tools should be used to remove dust, such as wiping with lens paper or cotton ball moistened with alcohol.
Instrument cleaning TIPS:
In use, it will be stained with greasy, glue, sweat and other dirt, and rust and mildew will occur when stored carelessly. These dirt will have an extremely negative impact on the life and performance of the instrument. The purpose of cleaning is to remove dirt on the instrument.
There are usually two types of cleaning methods for the instrument. One is mechanical cleaning, that is, cleaning with shovel, scraping, brushing, etc.; the other is chemical cleaning, that is, cleaning with various chemical decontamination solvents. The specific cleaning method depends on the condition of the dirt attached to the surface and the nature of the dirt.
