5 Occupational safety

5.1. General requirements

Prior to work start, instruct on OT of workers and crane operators with log entry. Familiarize with this PPRK for painting.

Protect the work area with signal fencing as per GOST 12.405989. Display warning signs.

Before starting each shift, the master must carefully inspect the place of work, evaluate the situation. Then familiarize the workers with the nature of the upcoming work, with the state of the workplace, passages to it. Indicate safe working methods, safety devices use methods, places of safety belt carbine attachment, as well as ways of personnel evacuation in case of danger.

Personnel during operation shall be in helmets and with safety belts.

In the area of dismantling works, all current-carrying elements must be disconnected or reliably protected.

When operating at the height of the safety belt carbine of the installer, it must be fixed to the safety rope.

Welding and gas cutting of metal shall be performed in accordance with the requirements of GOST 12.3.00386, SNiP 12032001, GOST 12.1.00476.

Persons not younger than 18 years of age, trained under a special program, certified by the qualification commission with the participation of the inspector of Rostekhnadzor and having a certificate for the right to carry out these works, as well as drivers of lifting cranes who have the corresponding certificate, after undergoing industrial training, certification of the qualification commission with the participation of the inspector of Rostekhnadzor and issuing the certificate of the slingshot, are allowed to work independently as a slingster.

Admission of the slingshot to independent work is carried out by order of the enterprise.

Prior to the rafter's admission to independent work, it is necessary to conduct a briefing in the scope of the labor protection instruction and familiarize under the signature with slinging, storage and process instructions for carrying out work using lifting mechanisms. This should be done when transferring the slingshot from one site to another inside the workshop and periodically, at least in 3 months;

During work, the slingshot must carry a certificate equipped with a photo card and present it at the request of the inspector of Rostekhnadzor, GPM supervision workers, an HSE engineer, persons responsible for the non-dangerous operation of lifting cranes and a crane driver.

In his work, the slinger is subordinate to the person responsible for the safe operation of cranes.

The number of slings serving one crane is determined by the enterprise administration. When two or more rafters work, one of them is appointed senior, who manages their work and gives commands to the crane driver.

Slingshot shall:

Observe the established internal labor regulations and fire safety requirements.

Perform only the work that is instructed and approved by the master.

Work in normal work clothes, protective helmet with armband red or orange.

Do not follow the instructions if they are contrary to the safety requirements and this instruction.

Be able to provide first aid.

Immediately inform the master of the accident.

Hazardous production factors in the performance of works by lifting cranes are:

- lifting cranes. When the distance between the protruding parts of the crane and the laid load is less than 700 mm, people can be clamped.

- rotary platform of boom crane. If the distance between the platform and the wall (column, load) is less than 1 m, people can be clamped.

- lowering (lifting) cargo near the wall, column, equipment or loading (unloading) of vehicles. When a slingshot is located between the load and the wall, column, equipment or side of the vehicle, it may be clamped.

- a load with articles (tools) attached to it or a load consisting of several parts poorly connected to each other. When lowering and moving such loads, injury with falling elements is possible.

- protruding strands of rope sling in places of their braiding. It is possible to injure open parts of the body and visual organs.

- electrical voltage passing through steel structures of boom crane, in case of contact with boom (rope) of wire by active power transmission line. In this case, when contacting parts of the crane (slings, cargo), electric shock can occur.

5.2. Safety requirements before operation

Familiarize yourself with the nature of the works and goods to be delivered.

Before use check serviceability of removable load-gripping devices and presence of tag (stamp) on them with designation of number, lifting capacity, test date and angle between branches for special-purpose slings.

Check serviceability of container and presence of inscriptions on its purpose, number, own weight and weight of cargo, for transportation of which it is intended.

Load-gripping devices and packagings with wear above permissible standards and without tags or inscriptions are not allowed for operation.

Check availability and serviceability of accessories (braces, crimps, hooks, ladders, liners, special slings, etc.)

During installation and operation of the boom crane, the following safety requirements shall be observed:

- it is not allowed to install the crane on fresh ash soil, on the floors of trays and routes, and on sites with a slope exceeding the one specified in the certificate.

- if, when tying the lifting machine, the approximation dimension (the distance between the turning part of the crane, hoist (tower), crane-manipulator at any their positions and structures, stacks of goods and other objects) is less than 1 m, it is necessary to shield the rotation area of the rotating part taking into account the approximation dimension with a signal fence. In this case, the person responsible for the safe operation of the lifting machine checks the installation of the lifting machine in the parking lot and only after that gives permission to carry out the work.

When performing work at height, the employee must be fastened to the safety rope with a safety belt.
