During construction works it is necessary to carry out environmental protection measures in accordance with the requirements of SNiP 12012004 - "Organization of Construction Production" Section 11 - "Environmental Protection."

The following wastes are generated during construction:

- hazard class 5 - soil not contaminated with hazardous substances 1.2 m3/period is used in planning works;

- Metal residues - 60 kg/period, retained and exported for further use.

No production and consumption waste is generated during the operation of the warehouse.

7. General Health and Safety Measures for Erection

During the briefing, pay special attention to the following sections of Safety Precautions:

1. Operation of lifting machines and mechanisms;

2. Operation of tools;

3. Loading and unloading works;

4. Electrical safety

5. Work at altitude;

6. Installation works;

7. Electro - gas welding works.

Persons who have undergone a medical examination are allowed for installation work. All installation personnel shall be provided with helmets, and persons working at height with safety belts and shoes with a sole that prevents sliding.

When performing installation work, ensure that the organization of workplaces ensures the safety of the work.

Work places shall be equipped with floors, fences, protective safety devices.

It is forbidden to install the equipment simultaneously at different elevations along the same vertical line.

Locations for lifting and moving units shall be well illuminated. In case of insufficient lighting of the place of work - the work is prohibited.

The alarm shall be arranged in such a way that all signals to the crane driver and the winch motorist, as well as the workers on the drawers, are supplied only by one person responsible for lifting or a specially appointed signalman.

All works related to lifting, transportation and installation of units shall be carried out under the direct supervision of the works manufacturer responsible for safe maintenance of these works.

The manufacturer of works is obliged to:

- In case of horizontal movement of blocks lift not less than 0.5 m higher than obstacles encountered in the way.

- Rigging devices and slings shall be tested before use. In addition, slings must comply with the requirements of:

Regardless of the above requirements, general mandatory safety measures shall be observed in accordance with the current TB rules for construction and installation work and the Ministry approved safety instructions for certain types of work.

a) to study the project of works execution, to establish the procedure of works execution and measures ensuring their safety,

b) ensure order and cleanliness at workplaces;

c) check the condition of tools, devices mechanisms, power tools (correct switching on, insulation state, grounding reliability, etc.), fire extinguishing means

d) make sure that the upcoming work does not pose a danger to the life and health of workers.

The manufacturer shall specify the hazardous area boundary before commencing work. The danger area shall be marked with visible warning signs or inscriptions.

The presence of unauthorized persons in the installation work area is strictly prohibited.

The weight of the lifted cargo, taking into account the lifting devices, shall not exceed the maximum lifting capacity of the crane. Lifting of loads close to crane lifting capacity shall be performed in two receptacles:

first, the load is lifted to a height of 100 mm (check the suspension, stability and reliability of the crane brakes), then to the required height. Do not pull (draw) the units with lifting mechanisms. It is not allowed to sling the cargo in unstable position, correct the position of the elements of slinging devices on the raised load, pull the cargo in case of oblique arrangement of load ropes.

Lifting of elements must be smooth without jerks and tremors. During lifting, swinging of elements is not allowed, it is forbidden to transfer structures with cranes above the work station of installers and above the adjacent grip.

In order to prevent emergency situations, it is forbidden to:

- after disabling the load, send a signal to the crane driver to lift the slings, not making sure that the slings are retracted from the load by a distance ensuring their free lifting;

- install structures by means of their dragging at oblique tension of rope of lifting mechanism;

- be on elements and structures during their lifting, movement and installation;

- move the installed structures after their disassembly;

- use additional ladders for disassembly and installation of temporary anchorages;

- lift structures and elements that do not have mounting loops, ensuring their safe slinging and installation;

- go over the installed elements and structures that do not have fences and stand on them;

- use sledgehammers to force the structure into place;

- put the mounting devices and tools on the mounted structures and at the edges of the floors.

The following requirements must be strictly observed outside working hours:

- hook holder must be in upper position;

- do not leave slings and other GPS on hook race.

Install protective barriers according to GOST 12.4.05989 along the contour of the finished slab and open openings, if it is impossible to install protective barriers, use safety belts.

Ladders and ladders for the work of installers shall meet the requirements of 7.4.237.4.30 SNiP 12032001.

A two-way radio communication must be established between the crane operator and the sling operator.

Familiarize under the signature with the PPR data:

- person responsible for safe operation of cranes and for safe operation of removable load-gripping devices and containers;

- crane operators;

- installers.

Storage of lubricants and gas cylinders at the construction site is not provided. Deliver as required according to process requirements.

Places of fire works and installation of welding units and transformers shall be cleaned from burned materials within a radius of at least 5 meters.
