20. Loading and welding
The loading and unloading processes are carried out by qualified and well-trained rigging teams under the guidance of a selected manager who has been certified by the commission in full compliance with safety engineering during the construction of pipelines.
Pipes from transport unload lifting means, equipped with certain devices that are designed for this. Before unloading, special platforms and vehicles are secured with shoes or other means with special slits. After that, the crane is fixed at a distance of more than 1 m from the wall of the car. When unloading pipes it is prohibited to be in a gondola, near materials or on a working platform.
Safety regulations at work comply with all pipe layers without exception. When loading a section on an auto train, it is strictly forbidden to be near a vehicle or a dissolution. It is also forbidden to be close to the submerged section. During welding, the pipe joints are protected from moisture using:
• shelters;
• portable shields;
• awnings.
In times of seasonal cooling, they are provided with means of individual heating. When working at the pipe joints use light inventory ladders and protective mats that protect the welder from colds.
During manual boiling, the welder who is involved in the work processes inside the pipeline must be in a protective helmet where the air enters. Near the work carried out near the pipe must be a couple of people who are needed for insurance and maintain a signal contact with the worker. All this provides the technology of construction of trunk pipelines.


21. Chimney and insulation works
For mixing bitumen and gasoline use special containers. It is forbidden to use open fire closer than 50 meters from tanks. Bitumen mastic is prepared in a certain place. Primer and mastic manufacturing sites must be equipped with fire-fighting equipment:
• fire extinguishers;
• shovels;
• boxes with dry sand and technical felt.
The cleaning and insulation of the pipeline is carried out under the direction of the head of the mechanized column section. When carrying out cleaning of the pipeline, it is only possible for the machinist to be present near the pipe cleaning and pipe insulation mechanisms.
Before commissioning, check the level of knowledge of safety regulations, compliance of an object with safety regulations during the construction of main pipelines. Workers are required to provide the necessary tools, equipment, special clothing and personal protection tools. During the testing of the pipeline at the purge pipe, a special protected area is organized, on which it is forbidden to be a stranger.
