Safe Operation

1. General requirements for labor protection

1.1. Persons at least 18 years old, trained and certified in the prescribed manner, who have passed a medical examination and briefing at the workplace, and who have a certificate with a photograph for the right to perform this type of work, are allowed to operate and transport cylinders.

3. Safety requirements during work

3.1. Operation, storage and transportation of cylinders with compressed and dissolved gases (oxygen, acetylene, propane) must be carried out in accordance with the requirements of the device regulations and the safe operation of pressure vessels.

3.2. Upon receipt of the cylinders in the warehouse, they must be inspected to ensure that:

there are no dents or damage on the cylinder body:
the expiration date of the cylinder indicated on the stamp has not expired;
the valve has a protective cap;
valve is correct.

3.3. Cylinders with compressed and liquefied gas must be loaded and unloaded with extreme care. Loading and unloading must be carried out by two workers, while it is impossible to unload the cylinders with the valve down, throw them and hit one against the other, because due to the high pressure inside the cylinder and the additional local increase in stress upon impact, it can cause an explosion.

3.4. Cylinders with oxygen and acetylene are placed in cars no more than three rows and no higher than the sides on special racks with gaskets. The body of the car must be thoroughly cleaned of debris, especially of any kind of oil.

3.5. Oxygen cylinders from the place of unloading should be moved only on special stretchers or trolleys. You can not carry them on your shoulders, because if accidentally dropped, an explosion may occur.

safety caps must be screwed on cylinders to failure;
cylinders must be placed in special nests lined with felt;
when loading more than one row, special spacers must be used;
during loading and unloading, it is not allowed to drop cylinders and hit each other;
cylinders are stacked only across vehicles.

3.12. When welding outdoors in winter, carbon dioxide cylinders should be placed in insulated rooms to prevent freezing.

3.13. The combined transportation of oxygen and acetylene cylinders is permitted under the following conditions:

no more than 10 cylinders can be transported at the same time (in total);
acetylene cylinders are thoroughly cleaned of traces of oil;
cylinders must be stacked on wooden stands.

3.13. In summer, the cylinders must be protected from the sun's rays with a tarpaulin.

3.14. The reducer is designed to regulate the gas flow, lower and automatically maintain the gas pressure to the working one.

3.15. Industrial gearboxes are standardized in the following types:

B - balloon, R - ramp, C - network, A - acetylene, K - oxygen, M - methane, P - propane-butane.

Cylinder reducers for various gases differ in the size and design of the connecting unit, the conditional color assigned to the corresponding gas.

3.16 It is forbidden to use the gearbox without a pressure gauge or with a faulty pressure gauge.

Cylinder storage

3.13. In the working position and during storage, the cylinders must be in a vertical position. Store empty cylinders separately from filled cylinders.

3.14. Gas cylinders should be stored with caps screwed onto them.

3.15. Cylinders for gas-flame work must have a distinctive color.

3.16. Cylinders with cracks, dents, risks with a depth of more than 10% of the wall thickness are rejected and withdrawn from service.

3.17. When storing and transporting, make sure that they do not get oil.

3.18. Cylinders must be returned to the warehouse with caps screwed on and valves closed.

Storage of calcium carbide

3.19. Drums with calcium carbide should be stored in a dry, protected from moisture, well-ventilated area, with a light roof type, without attic floors.

The warehouse building must have lighting, sewerage, heating.

3.20. The warehouse must be provided with carbon dioxide fire extinguishers, asbestos cloth and a box with dry sand.

3.21. Smoking is prohibited in the calcium carbide warehouse.

4. Safety requirements in emergency situations

4.1. When receiving a thermal burn, if the victim's clothes caught fire. You need to quickly throw any dense fabric on it or bring down the flame with water.

4.2. In case of small-sized burns of the 1st and 2nd degree, a sterile bandage should be applied to the burnt area of the skin and the victim should be sent to a medical institution. Notify the work manager. In case of severe and extensive burns, the victim must be wrapped in a clean cloth or sheet without undressing him, covered warmer, and calm until the doctors arrive.

5. Safety requirements upon completion of work

5.1. After completion of work, carefully check the condition of the workplace, if gas-electric welding work was carried out, rinse these places with water.

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. ... >>

Asus Transformer Pad Infinity tablet with 2560x1600 screen and Nvidia Tegra 4 processor 12.06.2013

Asus has officially unveiled a new version of the Transformer Pad Infinity tablet computer. The product received a new display and a different platform, and its appearance on sale is expected in the autumn of this year.

If the hardware platform of the previous version of the flagship Asus tablet running Android OS was based on the Nvidia Tegra 3 single-chip platform, then the new model uses the Nvidia Tegra 4 SoC, whose CPU runs at 1,9 GHz. The amount of RAM has increased to 2 GB, and the display resolution with the same diagonal of 10,1 inches has increased to 2560 x 1600 pixels (pixel density - 299 per inch). As before, the screen is made on an IPS type panel.

The tablet configuration also includes two cameras with a resolution of 5 and 1,2 megapixels, a dual-mode Wi-Fi 802.11a / b / g / n wireless adapter with Miracast technology support and a Bluetooth 3.0 + EDR module, 32 GB of eMMC memory, a slot for memory cards microSD micro-HDMI video output. Due to the latter, it provides an output to an external screen of a video image with Ultra HD resolution.

Traditionally, the Transformer Pad Infinity will be available in two versions: as a standalone device or as a tablet + keyboard set. The latter contains a USB 3.0 port, an SD memory card slot and a 16 Wh lithium-polymer battery. At the same time, the capacity of the battery installed in the tablet itself is 31 Wh. The overall dimensions and weight of the mobile device are 263 x 180,8 x 8,9 mm and 600 grams, respectively, the dimensions and weight of the docking station are 263 x 180,8 x 7 mm and 450 grams, respectively.

The approximate cost of the Transformer Pad Infinity itself in the US is $400. For the presence of the keyboard in the kit will have to pay another $100.
