17.Classification of storage tanks for oil and oil products
Oil storages are made of materials that are not amenable to ignition. Bunkers come in 3 types:
• ground;
• semi-underground;
• underground.
There are specific instructions, requirements and standards for installing each of the types presented. Now the most common are surface vertical structures based on steel. They, as a rule, have a cylinder shape, and such products belong to the RVS type.
Oil savings are formed at small bases and gas stations, where equipment for storing oil is represented by ground and underground RHS. And in order to store high-quality fuel oil, use special reinforced concrete products. Products from oil under strong vapor pressure are stored in certain engineering structures with a floating pontoon.


18. Technique and technology of construction of pipelines
Modern pipeline construction technology is successfully operating in different climatic regions of the regions, including at large distances from large industrial complexes. Installation is carried out throughout the year with the help of brigades and columns equipped with various mechanized equipment. For each of them is fixed a small section of the road.
In this case, safe methods are selected on the basis of the main functions provided by safety. To prevent emergencies and accidents during installation, a set of precautions is in place. To this end, is carried out:
• instruction that works according to safety regulations;
• manning of mechanized columns and workers with the necessary vehicles;
• constant inspection of equipment, devices, tools;
• installation of warning signs, protective mechanisms;
• allocation of individual protective equipment (clothing, shoes, etc.) to the team.


19. Basic safety regulations for pipeline construction
The main production processes, which correspond to the technology project and the organization of the construction of main pipelines, are being established at the tap. Conduct the necessary production processes, prepare parking for vehicles and the supply of gas and lubricants materials near the outlet is not allowed. Moreover, the organization of places for breaks and meals is prohibited.
Improving the roadway. Clearing the road from trees and bushes is the main direction of ensuring production safety. The area of ​​forest removal is blocked with fences with prohibited signs or inscriptions informing people about the danger. They are placed at a distance of 50 m from the border of the territory. Objects are not allowed to be accessed by strangers. Workers who are involved in the removal area are required to wear safety helmets.
Before carrying out excavation work, sites for digging underground engineering trenches are prepared. If there are any pipelines, the organization that is engaged in construction must have a permit, fixed in writing to carry out excavation work from the institutions that are responsible for this process in these areas.
At the points of trenching and communications, production takes place in strict compliance with safety regulations for the construction of steel pipelines in the presence of an engineer or other responsible person. At a distance of less than 2 m from underground pipes, the earth is removed through manual labor. At the same time works by means of digging machines are allowed.
