Procedure for servicing pressure vessels. Personnel servicing pressure vessels, etc. General safety requirements

Vessels operating under pressure require special operating rules and registration with Rostekhnadzor. In the article you will find detailed explanations and sample documents.

Read in the article:

Pressure vessels: definition

Pressure vessels are hermetically sealed containers designed to technological processes(chemical, thermal, others). Such equipment is used for storing and transporting gaseous, liquid and other substances and can be permanently installed at the enterprise or be mobile.

Operation of pressure vessels

The operating procedure is regulated by the order Federal service on environmental, technological, nuclear supervision dated March 25, 2014 No. 116.

The main responsibilities of the operating organization include:

• commissioning of equipment, putting it into operation, registration with Rostechnadzor;
• supervision of good condition and production control;
• execution maintenance, inspection, repair;
• decommissioning.

Regulatory regulation of production processes using equipment operating under excess pressure.

Persons who are trained, certified and have a certificate for the right to service vessels may be allowed to service vessels.

Training and testing of knowledge of personnel servicing vessels should be carried out in educational institutions, as well as in courses specially created by organizations.

Persons who have passed the exams are issued certificates indicating the name and parameters of the working environment of the vessels to which these persons are authorized to service.

The certificates are signed by the chairman of the commission.

Certification of personnel servicing vessels with quick-release lids, as well as vessels operating under the pressure of harmful substances of hazard classes 1, 2, 3 and 4 according to GOST 12.1.007-76, is carried out by a commission with the participation of an inspector from Rostechnadzor of Russia, in other cases the participation of an inspector not necessary in the work of the commission.

The Rostechnadzor body of Russia must be notified of the day of the examinations no later than 5 days in advance.

Periodic testing of the knowledge of personnel servicing vessels should be carried out at least once every 12 months. An extraordinary knowledge test is carried out:

when moving to another organization;

in case of changes to the instructions for the operating mode and safe maintenance of the vessel;

at the request of the inspector of Rostekhnadzor of Russia.

If there is a break in work in their specialty for more than 12 months, personnel servicing vessels, after testing their knowledge, must, before admission to work, independent work undergo an internship to restore practical skills.

The results of testing the knowledge of service personnel are documented in a protocol signed by the chairman and members of the commission with a mark on the certificate.

Permission of personnel to independently maintain vessels is formalized by an order for the organization or an order for the workshop.

The organization must develop and approve in accordance with the established procedure instructions on the operating mode and safe maintenance of vessels. For vessels (autoclaves) with quick-release lids, the specified instructions must reflect the procedure for storing and using the key-mark. The instructions must be located at workplaces and issued against signature to service personnel.

Diagrams for connecting vessels must be posted at work places.

18.4 Lighting of workplaces of industrial enterprises: natural, artificial, combined, emergency, security and duty (SNiP 23-05-95).

Natural light - illumination of premises with sky light (direct or reflected), penetrating through light openings in external enclosing structures. Natural lighting is divided into

- lateral

- upper

- combined (top and side)

Side natural lighting- natural lighting of the room through light openings in the external walls.

Overhead natural lighting- natural lighting of the room through lanterns, light openings in the walls in places where the heights of the building differ.

Combined natural lighting- a combination of top and side natural lighting.

Combined lighting - lighting in which natural lighting, which is insufficient by standards, is supplemented with artificial lighting.

Artificial lighting divided into:

Working

Emergency

Security

Duty

Work lighting - lighting that provides standardized lighting conditions (illumination, lighting quality) in premises and in places where work is carried out outside buildings. Working lighting should be provided for all areas of buildings, as well as areas of open spaces intended for work, the passage of people and traffic. For rooms with zones with different natural lighting conditions and different operating modes, separate control of the lighting of such zones is necessary. Lighting in the workplace is standardized depending on the level of visual work. Visual work category- depends on the smallest or equivalent size of the object of discrimination in mm.

Emergency lighting - lighting for continued work in case of emergency shutdown of working lighting. Emergency lighting is divided into lighting:

- security

- evacuation

Security Lighting- lighting for continued work in case of emergency shutdown of working lighting. Safety lighting should be provided in cases where the shutdown of working lighting and the associated disruption of maintenance of equipment and mechanisms may cause:

Explosion, fire, poisoning of people

Long-term disruption of the technological process

Disruption of the operation of power stations, radio and television transmission and communication centers, control centers, pumping installations for water supply, sewerage and district heating, etc.

Violation of the regime of children's institutions, regardless of the number of children in them. The safety lighting standard is at least 2 lux.

Evacuation lighting- lighting for evacuation of people from the premises in case of emergency shutdown of normal lighting. Evacuation lighting in premises or in places where work is carried out outside buildings should be provided for:

In places dangerous for the passage of people;

In passages and staircases used for evacuation of people, when the number of evacuees is more than 50 people. etc. The evacuation lighting standard is at least 0.5 lux.

Security lighting should be provided along the boundaries of areas protected at night. The standard for security lighting is at least 0.5 lux.

Emergency lighting - lighting during non-working hours.

Artificial lighting is achieved through:

General lighting

Combined lighting

Local

General lighting- lighting in which lamps are placed in the upper zone of the room evenly (general uniform lighting) or in relation to the location of equipment (general localized lighting).

Combined lighting- lighting in which local lighting is added to general lighting.

Local lighting- lighting, additional to the general one, created by lamps that concentrate the luminous flux directly at the workplace.

. Providing facilities with primary fire extinguishing means

463. When determining the types and quantities of primary fire extinguishing agents, the physical, chemical and fire hazardous properties of flammable substances, their interaction with fire extinguishing agents, as well as the area of ​​production premises, open areas and installations should be taken into account.

464. Equipment for technological equipment with fire extinguishers is carried out in accordance with the requirements of technical specifications (passports) for this equipment.

465. The choice of type and calculation of the required number of fire extinguishers at the facility (indoors) is carried out in accordance with Appendices 1 and 2, depending on the fire extinguishing ability of the fire extinguisher, the maximum area of ​​the premises, as well as the fire class.
