Installers are required to comply with labor safety requirements to ensure protection from the effects of hazardous and harmful production factors associated with the nature of the work: Location of workplaces in a large area height; Moving structures; Fall of overlying materials and tools; Moving machines and their working parts; Overturning of machines, falling of their parts To protect against mechanical influences, installers are required to use the following free of charge provided by employers: cotton suits with water-repellent impregnation, leather boots, combined mittens, as well as suits with insulating padding and felt boots for winter period Installers must wear safety helmets while on the construction site. In addition, when working at height, installers must use safety belts and safety devices, and when working in wells, safety belts and hose gas masks for respiratory protection. While on the territory of the construction (production) site, in production and service premises, work areas and workplaces installers are required to comply with the internal rules adopted in this organization. The admission of unauthorized persons, as well as workers in a state of intoxication, to the specified places is prohibited. In the course of daily activities, installers must: 1
2 Use small mechanization tools during work for their intended purpose, in accordance with the instructions of the manufacturers; Maintain order in workplaces, clear them of debris, snow, ice, and prevent violations of the rules for storing materials and structures; Be careful while working and avoid violating labor safety requirements. Installers are required to immediately notify their immediate or superior work supervisor of any situation that threatens the life and health of people, of every accident that occurs at work, or of a deterioration in their health, including about the occurrence of an acute occupational disease (poisoning). 2. SAFETY REQUIREMENTS BEFORE STARTING WORK Before starting work, the installer must: 2.2. Present your knowledge test certificate to the work manager safe methods and work methods and undergo on-the-job training taking into account the specifics of the work performed; Wear a helmet, overalls, and safety shoes of the established type; Receive a task to complete the work from the foreman or manager. After receiving the task, installers are required to: Prepare the necessary tools personal protection, check their serviceability; Check workplace and approaches to it for compliance with safety requirements, check with the work manager the degree of gas contamination of wells and chambers; Select the technological equipment and tools necessary to perform the work, check their compliance with labor safety requirements; Inspect the structural elements of pipelines intended for installation and make sure that they have no defects. Installers should not begin work in case of the following violations of safety requirements: Malfunctions of technological equipment, protective equipment for workers, tools specified in the manufacturers' instructions; Untimely carrying out of regular tests of technological equipment, tools and devices; Failure to carry out regular tests in a timely manner or the expiration of the service life of protective equipment for workers established by the manufacturer; 2
3 Insufficient lighting of workplaces and approaches to them; Defects in pipeline structural elements intended for installation; Violation of the stability of slopes of excavations where work should be carried out; Detection of loss of stability of previously installed pipelines; Lack of a gas mask or other protective equipment when working in gas-filled wells and chambers. Detected violations of safety requirements must be eliminated on our own, and if it is impossible to do this, installers are required to inform the foreman or work manager about them. 3. SAFETY REQUIREMENTS DURING WORK Work in places where harmful gas may appear should be carried out only as directed by the work manager after an analysis of the air environment. In the presence of gases, work should be carried out only after the workplace has been provided with ventilation or installers have used respiratory protection. Work in wells, pits or closed containers should be carried out using hose gas masks, while two workers, being outside the well, pit or container, must insure the installers using ropes attached to their safety belts When performing work on laying external pipelines, installers are required to: Use a specially designed hook to open or close manhole covers; When working with power tools of the first or second class of protection, use personal protective equipment (dielectric gloves, galoshes, mats); When working in areas where vehicles can pass, use barriers with a road sign “Transmission prohibited, work in progress!”, a glowing red light. If a malfunction of a portable electric lamp or transformer, as well as other power tools or electrical wiring is detected, installers are required to stop work and notify the foreman or supervisor. When working at a height of over 1.3 m on scaffolding, stepladders or scaffolding without guardrails, installers are required to use safety belts, which should be secured in places specified by the supervisor. 3

Pieces of cold metal should be added to the molten mass of lead using metal tongs. In this case, pieces of cold lead must be clean and dried. Buckets with hot mastic should be lowered into a well or trench along a vertical box using strong ropes or cables. During the installation of a pipeline, installers are required to: Use specially prepared access systems and scaffolding means for passage and work; When tightening nuts, use wrench, corresponding to their sizes; Do not smoke in cells and wells, and do not use open fire near hatches; Do not allow people to be under the load being lowered or lifted, and when working with the winch, do not guide the cable on the drum with your hands or feet; Check the compliance of the holes for flange connections only using tapered mandrels and assembly plugs; If you have cuts or scratches on your hands, do not work in a well with fecal water. When using a crane to supply pipeline structural elements into a trench, installers must comply with the requirements for installing and moving loads with a crane, set out in the work design (WPR) or technological map. Place construction materials at the edge of the excavations. with unreinforced walls should be outside the soil collapse prism at a distance of at least 1.5 m from the edge of the excavation. Before delivering pipeline structural elements to the installation site in the design position, they should be cleared of snow, soil, ice and freed from foreign objects. When installers and electric welder, when welding pipes, to protect the eyes, installers must use specially designed safety glasses or shields with tinted glasses. Installers with a slinger (rigger) certificate are allowed to sling loads. When supplying pipes for laying in a trench, people are not allowed under the load being moved. Slinging of pipeline fittings ( valves, plugs) should be carried out by their body; slinging by individual parts (rods, flywheels) is not allowed. Approaching the load is permitted only after lowering the load to a level no higher than 0.5 m from the design position. 4
5 3.18. The unslinging of pipeline elements installed in the design position should be carried out after securing them in accordance with the design. The bottom of the trench should be cleared of collapsed soil after temporarily supporting the pipeline on supports laid across the trench. It is permitted to begin testing the equipment only after timely warning of surrounding persons and obtaining permission from the test supervisor During equipment testing, it is not allowed to: Remove protective guards; Open hatches, fences, clean and lubricate equipment, touch its moving parts; Check and correct electrical circuits, electrical equipment and automation devices During pneumatic tests of pipelines located in trenches, a danger zone must be established, the size of which is indicated in the table. The boundaries of the danger zone must be marked with signal barriers or safety signs. Persons are not allowed to be in the hazardous area during the period of air injection into the pipeline and when the pipeline is kept under pressure during strength testing. Inspect, tap or service the pipeline, connect or disconnect the lines supplying air from the compressor to the pipeline only after stopping the air supply and reducing pressure to atmospheric Installation of pipelines near electrical wires within a distance equal to the longest length of the mounted unit, it should be carried out with the voltage removed. 4. SAFETY REQUIREMENTS IN EMERGENCY SITUATIONS In case of detection of a malfunction of lifting or rigging equipment, technological equipment and scaffolding equipment, installers must immediately suspend the operation of the lifting equipment and notify the crane operator and the person responsible for the safe performance of work on moving cargo by crane. If an unstable position is detected elements of pipelines, violations of the fastening of trench walls or scaffolding means, installers are obliged to notify the work manager and foreman about this. If a rupture or damage to a pipe is detected during its testing, installers must immediately stop testing, 5
6 relieve pressure in the system and resume testing only after troubleshooting. 5. SAFETY REQUIREMENTS AT THE COMPLETION OF WORK At the end of the work, installers are required to: Place the lifting devices and technological equipment used during the work in the designated storage area; Remove dirt, rinse and put away the instrument and small details carefully place materials and elements of building structures in places intended for their storage; Close the hatches of wells and chambers or place fences around them and appropriate road sign“The passage is closed, work is underway!”, and also turn on a red lantern to illuminate this place; Inform the work manager or foreman about any problems that arose during the installation of pipeline structures. 6

8. INSTALLATION OF PIPELINES
8.1. The deviation from the straightness of the welded (glued) pipeline, measured along the generatrix, should not exceed 2.0 mm at a distance of 200 mm from the weld. Deviations from straightness of welded plastic pipelines can be eliminated by heating them with hot air.
8.2. Installation work process pipelines from plastic pipes should be carried out in accordance with the technological instructions given in the work design (WPR).
8.3. Before installation of pipelines from plastic pipes begins installation organization must complete the following preparatory work:
complete set of materials and products according to the nomenclature specified in the project and in accordance with the PPR. All materials and products must have documents certifying their quality;
preparation of covered areas for storing pipes, connecting parts, pipeline assemblies and other materials and products to meet at least two-shift requirements;
completing welding and installation equipment, devices and tools and performing their adjustment;
study by line engineers and foremen (team leaders) of PPR, working and regulatory documentation.
8.4. Before installation of pipelines made of plastic pipes begins, all construction, electrical and gas welding work, installation of process equipment and pipelines (steel, cast iron, non-ferrous metals and alloys, coated pipelines), as well as work on thermal insulation of these pipelines must be completed.
In the places specified in the project (in the walls of buildings and channels, ceilings, coverings and on columns), embedded parts must be installed under the supporting structures of pipelines, and in places where pipelines pass through foundations, walls, partitions and ceilings of buildings - cases. Embedded parts and cases must comply with the working drawings of the project and be installed in the hole with a tight fit supporting surfaces To building structures and followed by embedding with concrete.
Cases must be made from non-combustible materials; the gap between the plastic pipe and the case is carefully sealed with asbestos or other fireproof material.
Support structures must be installed for fittings and pipeline components.
8.5. Pipelines should be laid in accordance with the design on separate supports, hangers or on a solid foundation.
8.6. Installation of supports, hangers and support structures under pipelines must ensure the route and slope of the pipeline specified by the project. The deviation of the position of supports and supporting structures from the design should not exceed ±5 mm in plan (for pipelines laid indoors) and ±10 mm (for external pipelines); the slope in both cases should not exceed +0.001. To ensure the design slope of the pipeline, it is allowed to install gaskets under the soles of supports or on supporting structures. The slope of the pipeline must be checked using instruments or special devices.
8.7. The designs of supports, suspensions or solid foundations must be given in the project. It is allowed to use fasteners used for metal pipelines as separate supports and hangers. At the same time, in places where polymer pipes come into contact with metal parts there should be no sharp edges or burrs on them, and between the pipe and the clamp or pipe, bracket and support there should be a gasket made of plastic material (rubber, polyethylene, felt, etc.).
8.8. The design of the solid base should not interfere with the self-compensation of the pipeline, especially in places where it turns. The solid base must be made of fireproof materials.
When laying pipelines with detachable connections on free flanges, gaps (“windows”) must be provided at their locations in a solid base for their installation. The size of the gaps should ensure free movement of the flanges moving together with the pipeline in the process of compensating for temperature deformations.
8.9. Steel and steel-lined reinforcement should be secured to individual supports or building structures using clamps or brackets. Reinforcement made of plastic materials must be attached to building structures or a solid base with clamps or brackets.
8.10. Compensators must be installed according to the instructions given in the project.
8.11. Movable fastenings that allow axial movement of pipelines are made using clamps or brackets made of plastic or metal.
When fastening pipelines using metal clamps and brackets, a gasket made of elastic material must be installed between the pipe and the clamp; The width of the gasket must be 10 mm greater than the width of the clamp or bracket, or the clamp and bracket must have flanges, chamfers or rounded edges to prevent damage to the pipes during longitudinal movement of the pipeline.
8.12. Fixed fastenings of pipelines should be made using thrust ring pads welded (glued) to the body, made of pipe material. The pads must be installed on both sides of a fixed clamp (half-clamp) or bracket and cover at least 3/4 of the diameter of the pipe, with the exception of the points of contact with the support. In cases where pipeline movement must be ensured in only one direction, the linings are installed on one side.
8.13. Vertical sections of pipelines should, as a rule, be secured under a socket or flange connection, and on smooth sections of pipes - under ring linings made of the material of the pipes being secured, welded or glued to the pipe.
8.14. Pipelines laid on a solid base must be secured to it using clamps or brackets installed for horizontal sections every 1 m (for pipes D n up to 63 mm), 1.5 m (for pipes D n from 63 to 160 mm) and 2.0 m (for pipes D n over 160 mm), and for vertical and inclined sections - every 1.5 m (for pipes D n up to 63 mm) and 2.0 m (for pipes D n over 63 mm).
The length of sections of pipelines that do not rest on a solid base in places of turns and their connection to devices, equipment, fittings and flanges should not exceed 0.5 m (for pipes D n up to 63 mm) and 1.0 m (for pipes D n over 63 mm).
8.15. During the installation process, straight sections of pipelines must be laid on at least two supports, and units and blocks must be secured so that they cannot shift or deform under the influence of their own weight.
8.16. When laying pipelines underground, it is allowed to lay pipes along bends along a gentle curve in accordance with the requirements of SNiP for the production and acceptance of work during the construction of external networks and water supply, sewerage and heat supply structures. At an ambient temperature of 20 °C for pipes with an outer diameter of up to 315 mm, the radius of curvature is recommended to be: 30 D n (for LDPE pipes), 120 D n (for HDPE pipes), 200 D n (for PP pipes) and 300 D n (for PVC pipes). The radius of curvature at turns of HDPE pipelines with an outer diameter of over 315 mm, laid along a gentle curve, should be taken as follows: for type L pipes - at least 50 D n, SL type - at least 40 D n, type C - not less than 20 D n . At an air temperature of 10 °C, the radius should be increased by 1.5 times, and at a temperature of 0 °C - by 3 times. At negative ambient temperatures, laying pipelines along a flat curve is prohibited.
8.17. When laying pipelines without channels, excavation work must be carried out in accordance with the requirements of SNiP III-8-76 for the performance of work during the construction of earthen structures.
8.18. It is necessary to deliver plastic pipes from storage to installation and lay them out along the trench or channel immediately before installation work.
8.19. When laying without channels or laying in channels, pipelines with a length of 100 m or more should be installed, as a rule, in ready-made welded (glued) sections, which are then transported and laid out along the route.
8.20. Pipelines welded and glued at the edge are allowed to be laid in a trench no earlier than 24 hours after welding and gluing the last joint.
8.21. If pipelines are laid in a trench at a temperature environment above 10 °C (except for PVC pipes connected socket-to-socket on rubber rings), measures are necessary to reduce temperature stress: laying pipelines in a “snake” pattern, filling the pipeline cold water before backfilling, backfilling of the pipeline in the coldest time of day.
8.22. PVC pipes connected by sockets on rubber rings should only be installed in trenches. In this case, the air temperature should not be lower than minus 10 °C.
When connecting socket pipes on rubber rings, the following order of operations must be observed: cleaning the inner surface of the socket, the smooth end of the pipe and the surface of the ring, installing the rubber ring in the groove of the socket, applying an installation mark to the smooth end of the pipe, lubricating the smooth end of the pipe to facilitate pipe installation, pushing the smooth end of the pipe into the socket up to the mounting mark.
8.23. When installing a rubber ring into the groove of the bell, you must ensure that it fits snugly against the surface of the groove along the entire circumference.
To ensure the required gap between the end of the smooth end of one pipe and the inner surface of the socket of another pipe, a chamfer must be chamfered on the smooth surface of the pipe at an angle of 15° to the axis of the pipe and an installation mark must be applied with indelible paint or another method, which determines the depth of insertion of the smooth end of the pipe into the socket. The length of the chamfer at the smooth end of the pipe and the depth of its insertion into the socket must correspond to table. 24.

8.24. To facilitate the installation of pipes on rubber rings, it is allowed to use lubricants ( liquid soap, soap solution, glycerin, etc.), which do not destroy the material of the pipes and rings. Lubricating pipes with oils, grease and other similar lubricants is prohibited. To install pipes on rubber rings, it is usually necessary to use clamping devices. Pipes with an outer diameter of up to 160 mm can be assembled manually using various levers; In this case, measures must be taken to prevent damage to the surface of the pipes.

8.25. When laying PVC pipes with socket joints on rubber rings, supports should be provided in places of turns, branches and dead-end sections. The area of the supports must accommodate the magnitude of the forces arising when testing pipelines, given in table. 25.
8.26. As a rule, detachable flange connections of pipelines from plastic pipes should be assembled when positive temperature. The flange connection must be tightened by uniformly transversely (crosswise) tightening the nuts. The tightening force of the flange connection, assembled using a rubber sealing gasket, must ensure that the gasket deformation does not exceed 0.2-0.4 of its thickness; for gaskets made of other materials, the tightening force is selected experimentally to ensure the strength and tightness of the connection.
The protective covers provided for by the project on detachable flange connections of pipelines transporting acids and alkalis must be installed after testing the pipelines.
8.27. Thermal insulation should be installed after testing the pipeline in compliance with measures to prevent its damage (including installing gaskets made of tarpaulin, asbestos fabric or several layers of fiberglass under bandages and wire ties).
