Welding works – an integral part of construction and installation. They are conducted in small production, and in everyday life. This type of work is characterized by an increased degree of danger. In order to prevent various injuries, the welder not only must pass the appropriate training, but also acquire all the necessary means of individual protection.
There are typical rules that regulate the issuance of free ammunition by welders. These rules are developed and approved, they are required for execution. If the work in the cold season is made in the open air or indoors without heating, the welders must be issued a warm clothing set with a special lining. To protect workers from frostbite while contacting with frozen earth or snow, special litters are used made of refractory fabrics having an elastic layer.
To protect the hands of GOST offers several options. These are mittens from tarpaulin with or without kraga. The second option – mittens from a split, which can also be elongated. As a special shoe, it is allowed to use semi-boots from YUFTI or other skin type. It is important that special shoes have shortened tops.
It is impossible to work in shoes, in the sole of which there are inserts from the metal, and any lacing is prohibited.
If during the work there is a danger of electric shock, the welder when sitting in the posture or lying should have dielectric gloves and a rug. These requirements concern particularly dangerous premises and places where there is no automatic disconnection of the idle stroke.
The enterprise administration is also required to evaluate jobs in terms of danger of head damage. To avoid injuries, specialists should work in helmets. For greater amenities there are special helmets with a protective shield. When simultaneous work on welding with several employees on one vertical line occurs, it is necessary to establish protection: awnings or deaf flooring. Then on the welder, which is located below, will not be sparks and flats.
Mask and respirator
The need to use the USS for respiratory organs occurs in those moments when the maximum permissible concentration of hazardous substances in the air is broken. In welding, such gases can be accumulated as ozone, nitrogen or carbon oxides. There are situations where the amount of harmful gases is lower than dangerous, while the concentration of dust exceeds the norm. In these cases, anti-bind reusable respirators are used to protect organs of breathing.
When the concentration of gases and dust exceeds the permissible norms, and the work occurs in a closed room or a hard-to-reach place (for example, a huge capacity), welders must be provided with additional air supply through respiratory instruments. As such, it is recommended to use “PSh-2-57” hose gas masks or special machines for breathing “AFM” and “3M”.
Air that is supplied to breathing devices through the compressor must be absolutely clean. It is unacceptable for extraneous particles or hydrocarbons.
Welders’ eyes need to be protected from adverse electrical arc radiation, as well as from hot splashes arising during welding. To protect various shields with a screen and masks with glass inserts. For such categories of personnel, like a gas cutter or auxiliary worker, applies to the use of special glasses.
Points completely close the eye area, provide indirect ventilation. They are designed to protect the retina from ultraviolet. Utility workers should also be in special glasses. Glasses are often supplied with light filters, thanks to which ultraviolet and infrared rays do not affect the retina, they do not blind eyes from visible radiation.
GOST contains norms for protective materials. The welders are shown to be on the work in the costumes consisting of a jacket and trouser belonging to the category “Tr”, meaning protection against molten metal splashes. In the cold season, employees are put on to wear workwear with protective properties “TN”. It is specifically designed to protect from cold and frost. For example, “TN30” means that the costume can be used at a temperature mode up to 30 ° C.
Usually working suit is represented by a jacket and pants. It should be sewn in accordance with Goste, not to be too heavy and striking.
Specially designed for welding clothes are always marked with the sign “TR”.
This means that the cloth’s fabric does not deteriorate and does not light up from hot sparks. Most often for sewing take tarpaulin or skin. Material is treated with special heat-resistant substances.
Smaller cotton fabrics are allowed. However, they must be carefully impregnated with a chemical composition that protects from high temperatures. Polymer materials are applied to the skin on the skin. Acrylic resins are used for their manufacture. The resulting sprocket must withstand the effect of high temperature regime at least for 50 seconds.
According to GOST 12.4.103-83, in the warm season, welders must wear leather boots having a “Tr” marking. Socks such boots are made of metal. They are designed to protect against spray of burning metal and sparks, as well as from contact with hot surfaces. Welding Welding Welding Welding.
All shoes must be made of natural materials. In addition, it is covered with refractory chemical composition, which can not burn hot splashes of metal.
How to choose?
During welding work, such side effects occur as burning sparks and pieces of metal. Therefore, materials should be resistant to long-term exposure to high temperatures. Unacceptable melting that can lead to skin burns.
Safety equipment prohibits welding work without special shoes. This particular attention is also paid to materials. Since the hot splashes fall on the floor, the sole of the boot must resist the effects of high temperatures.
