the condition of the pressure gauge (checking in the laboratory of the State Standard, the presence of a red line on the scale of the pressure gauge, the arrow landing on zero);
operation of the safety valve;
integrity of the gauge glass.

3. Labor protection requirements during work

3.1. Sterilizer personnel are prohibited from:

supply steam to the sterilizer when the lids are not fully fixed;
turn on the sterilizer when the water level in the steam generator tank is insufficient;
open the lid of the sterilizer or loosen its fastening in case of excessive pressure in the sterilizer;
work on a sterilizer that has defects that reduce its strength and stability;
add water to the steam generator tank when it is under pressure;
work on the sterilizer after the expiration of the G.I. and pressure gauge checks;
leave the sterilizer unattended during its operation.

3.2. Load the sterilization boxes with the material to be sterilized. The effectiveness of sterilization depends on the packing density.

3.2. Close the cover and tighten it with clamps.

3.3. Turn on the power switch.

3.4. Set the pressure in the sterilization chamber to 0,1 - 0,2 kg/cm10. Air is expelled from the sterilization chamber for XNUMX minutes.

3.5. Sterilization in the sterilizer is carried out with saturated water steam with a temperature of 132 degrees, for 20 minutes. At a temperature of 120 degrees for 45 minutes.

3.6. At the beginning of sterilization, it is recommended to slightly open a special valve for 1 seconds 2-30 times to expel condensate from the sterilization chamber, which contributes to better steam penetration for better sterilization.

3.7. Opening the door of the sterilizer when sterilizing any solutions in it is allowed no earlier than 30 minutes after the end of sterilization

3.8. Prepared materials for sterilization must be affixed with a tag indicating the contents and the date of sterilization.

3.9. After each completed sterilization cycle, personnel must ensure that the required sterilization temperature has been reached during the sterilization of the objects loaded into the chamber.

3.10. When carrying out the following sterilization cycles, it is necessary to check the presence of water on the glass of the water indicator column and, if its level is above the lower mark and on the water indicator glass above the lower mark and on the water indicator column (at least 3 cm), you can not add water, but proceed to the next cycle sterilization. Otherwise, water must be added.

3.11. To fill the sterilizer with water, it is necessary to disconnect the sterilizer from the mains, release steam from the chambers,

3.12. If, during sterilization, the water level sensor turns off the electric heaters and the “no water” lamp lights up on the electrical panel, turn off the sterilizer, release steam from the sterilizer, fill with water.

3.13. When operating the sterilizer, personnel must observe:

cleanliness and good condition of all parts of the sterilizer;
prevent water from entering the electrical panel and electrical contact thermometer;
daily after finishing work, drain the water from the steam chamber.

4. Labor protection requirements in emergency situations

4.1. The sterilizer must be stopped in the following cases:

if the pressure in the sterilizer has risen above the permitted level, despite compliance with all requirements for the regime and safe maintenance of vessels;
in case of malfunction of safety valves;
upon detection of cracks, bulges, gaps in welds in the elements of the sterilizer;
in the event of a fire;
when the liquid level drops below the permissible level;
in case of malfunction of the cover parts;
in the event of a malfunction of the locking devices.

5. Labor protection requirements at the end of work

5.1. After completing the work, it is necessary to turn off the power supply and make sure that there is no pressure in it.

5.2. All shortcomings and malfunctions found during operation, the personnel must make an appropriate entry in the maintenance log and report to the person responsible for the safe operation of the sterilizer.

5.3. Wash your hands with soap and take a shower.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

High speed 16Gbps interface 31.01.2016

THine Electronics, a company specializing in the development of high-speed serial interfaces and LSIs for mixed signal processing, announced the creation of "high-speed interface technology with a bandwidth of 16 Gb / s." As usual in such cases, we are talking about throughput per line.

According to THine, this is the first solution of its kind in the world, suitable for internal connections in 8K TVs and other high-definition equipment. The manufacturer notes that the new technology can be used not only with THine's own V-by-One interface, but also with Fiber Channel 16GFC, PCI Express 4.0 (Gen4) and USB3.1.

The company is confident that the development will find application in PCs, computer centers, industrial electronics, on-board vehicle systems. Samples of integrated circuits that use the new technology should be ready in the first half of 2017. In the meantime, THine began to develop an interface with a bandwidth of 32 Gb / s or more.
