Safe Operation

Introduction

This Instruction establishes the basic safety requirements for the head of the diving descent when performing diving descents and works.

Each head of diving descents must know and comply with the requirements set forth in this Instruction, and the administration of the enterprise is obliged to create conditions for the production of safe diving descents and work, as well as to monitor the implementation of this Instruction by the head of diving descents.

1. General requirements for labor protection

1.1. The head of the diving descent is the direct supervisor of the diving and maintenance personnel of the diving station during the diving descent.

1.2. Every year, by order of the administration of the enterprise (territorial division), on the basis of the protocol of the diving qualification commission (VKK), a list of persons who have passed the knowledge test of the VKK and are admitted to lead diving descents must be determined.

1.3. Before the start of diving operations performed at individual sites (under conditions of an expedition or business trip), by order (instruction) of the administration of the enterprise (territorial division), on the proposal of the head of the diving service, heads of diving descents to diving stations are appointed.

In other cases, the appointment of the leaders of diving descents at the station before the start of work is carried out by a work order.

Appointment of diving descent leaders from among persons not specified in the annual order for the enterprise (territorial division) is prohibited.

1.4. The appointment of a leader of diving descents should be made taking into account the nature of the upcoming descents and in compliance with the requirements for his qualifications specified in clause 1.9 of these Instructions.

1.5. At each diving station there must be at least two divers with a permit from the VKK and appointed by order of the enterprise (territorial division) to lead the diving descents, one of which is appointed by the foreman (foreman) of the diving station.

The foreman (foreman) of the diving station, if he does not descend under water, performs the duties of the leader of the diving descent.

When the foreman (foreman) of the diving station descends under water, a diver admitted to lead the descents is appointed as the leader of the descent.

1.6. When two or more diving stations work simultaneously from a diving post, a diving descent leader is assigned to each station.

1.7. In case of incorrect actions of the leader of the diver, which can lead to an accident or an accident, the leader of the diving operations may remove the leader of the descents from his duties and lead the descent himself, and if he does not have permission to lead the descents, he must appoint another leader of the descent who has tolerance.

1.8. The return of the descent guidance is not made before the end of the descent (work under water is stopped, the working diver rises to the surface, and after that the return of the descent guidance is made). The acceptance of the descent guidance and the return of the descent guidance must be recorded in the diving log.

1.9. Persons with the following qualifications are allowed to lead diving descents:

• diver of the 2nd class - at depths up to 20 m;
• diving specialist, diving master or 1st class diver - at depths up to 60 m.

1.10. The head of the diving descent controls the work of the diving team and persons serving the descent, and is also responsible for the safety of the descending divers during the entire period of the diving descent (during decompression or therapeutic recompression on the surface, the transfer of leadership to the medical worker is carried out after the diver is placed in the pressure chamber and the pressure rises in it to a pressure corresponding to the stop depth from which the diver was brought to the surface).

1.11. The head of the diving descent is obliged:

• during the preparation and conduct of a diving descent, give instructions to divers and persons serving the descent on his own;
• upon completion of the work, take part in the preparation of documentation for the performed diving work, as well as in the preparation of diagrams, sketches and other materials based on the results of the work performed.

1.12. The head of the diving descent has the right to:

• proceed with the diving descent only after the detected malfunctions have been eliminated and the corresponding entry and signature by the person who eliminated the malfunction in the diving log and the diving station form (or in the form for a specific product);
• give permission for any changes in the situation (lowering or lifting of loads, tools, changing the length of the mooring lines or anchor chain, switching on individual systems, changing the air supply mode and other actions) that affect the safety of the diver, upon receipt of the consent of the working diver and after it report on readiness to change working conditions;
• suspend divers and service personnel from performing work in case of violation of technological discipline, requirements of the governing regulatory documents on labor protection or failure to comply with established regulatory tasks;
• stop the diving descent if changes in the situation or incorrect actions of the company's officials or the ship's administration can create an emergency.

1.13. The head of the diving descent may be entrusted with the responsibility for the medical support of divers, if he has undergone medical training under a special program and has the appropriate certificate.

In this case, the head of the diving descent must submit to the VKK a test for admission to the medical support of divers in the scope of the requirements of the medical part of RD 31.84.01-90. Re-testing of knowledge is carried out every 12 months.

The appointment of these persons for medical support is carried out by order of the administration of the enterprise after passing the test of the VKK.
