Question from Dmitry:

Hello! Please tell me if there are any regulatory requirements for checking and maintaining supply and exhaust ventilation and air conditioners in a private medical center, what kind of supervision monitors (checks) this? What is the frequency of such inspections and maintenance?

Reply to Dmitry:

Hello Dmitry.

According to clause 3.1.1. GOST 12.4.021-75 SSBT. Ventilation systems. General requirements for operation allow ventilation systems that have fully completed commissioning and have operating instructions in accordance with GOST 2.601-2006, passports, repair and operation logs. The operating instructions for ventilation systems must reflect issues of explosion and fire safety. Scheduled inspections and checks of compliance of ventilation systems with the requirements of this standard must be carried out in accordance with the schedule approved by the administration of the facility (clause 3.1.2. GOST 12.4.021-75). Preventive inspections of premises for ventilation equipment, cleaning devices and other elements of ventilation systems serving premises of categories A, B and C must be carried out at least once per shift, with the inspection results recorded in the operation log. Malfunctions detected in this case must be immediately eliminated (clause 3.1.3 of GOST 12.4.021-75). Cleaning of ventilation systems must be carried out within the time limits established in the operating instructions. A note about cleaning is recorded in the system repair and operation log (clause 3.2.7. GOST 12.4.021-75). You will find the form for the repair and operation log of ventilation systems in Appendix 10 RD 34.21.527-95 “Standard operating instructions for heating and ventilation systems of thermal power plants.”

The efficiency of the ventilation system in healthcare facilities should be checked once a year.

Rationale:

Heating, ventilation and air conditioning systems must provide standardized parameters of the microclimate and air environment of the premises in which medical activities are carried out. One of the most important elements of any building is a supply and exhaust ventilation system with mechanical and (or) natural impulse. The mechanical supply and exhaust ventilation system must be certified (clause 6.5 of SanPiN 2.1.3.2630-10 “Sanitary and epidemiological requirements for organizations engaged in medical activities”) (hereinafter referred to as SanPiN 2.1.3.2630-10). Quite often there is a violation associated with the operation of the supply and exhaust ventilation system - failure to check the effectiveness of its operation, which does not meet the requirements of clause 6.5 of SanPiN 2.1.3.2630-10. By virtue of this norm, once a year, operating efficiency checks, routine repairs (if necessary), as well as cleaning and disinfection of mechanical supply and exhaust ventilation and air conditioning systems must be carried out.

In accordance with clause 11.2. STO NOSTROY 2.24.2-2011 “Internal engineering networks of buildings and structures. Ventilation and air conditioning. Testing and adjustment of ventilation and air conditioning systems" (hereinafter - STO NOSTROY 2.24.2-2011) when operating heating and ventilation systems, you must have:
- passports of the established form for thermal units, heat consumption systems and ventilation units with protocols and reports of inspections and repairs;
-working drawings of equipment;
- executive diagrams of the heating unit and pipelines with numbering of fittings and equipment, arrangement of instrumentation and automation;
- logs of operation of heating and ventilation systems;
-factory instructions for servicing heat consumption and ventilation systems;
- job descriptions of service personnel.

According to clause 11.3. STO NOSTROY 2.24.2-2011 factory instructions must contain:
- brief description of the system or equipment;
- the procedure for starting, stopping and maintenance during normal operation and measures taken in emergency modes;
- the procedure for admission to inspection, repair and testing of the system or equipment;
- safety and fire safety requirements specific to a given system or installation.

The factory operating instructions for heating and ventilation systems must reflect the specific actions of personnel to eliminate system malfunctions, taking into account their nature and location of occurrence, the purpose of the serviced premises, the degree of influence of malfunctions on the performance of process equipment and the safety of operating personnel (clause 11.4 STO NOSTROY 2.24 .2-2011).

When carrying out scheduled preventive maintenance, the following documentation must be drawn up (clause 11.5 STO NOSTROY 2.24.2-2011):
- annual and monthly repair plans for heating and ventilation systems;
- statements of defects and volumes of work, estimates (if necessary);
-schedule and project for organizing repairs;
-required repair documentation;
- when carrying out reconstruction or modernization work
— approved technical documentation.

Goal: learn to calculate the frequency of scheduled maintenance and repair work. Draw up an annual plan - equipment maintenance schedule.

Progress:

1. Select equipment number by option (see Appendix 1)
2. We enter our equipment into the empty PPR schedule form.
3. At this stage, we determine the resource standards between repairs and downtime:
4. We look at Appendix No. 1 “Standards for the frequency, duration and labor intensity of repairs”, select the values ​​​​of the frequency of repairs and downtime during major and current repairs, and write them down in your schedule.
5. For the selected equipment, we need to decide on the number and type of repairs in the coming year. To do this, we need to determine the number of hours of equipment worked (the calculation is conditionally carried out from January) (see Appendix 2)
6. 4. Determine the annual downtime for repairs
7. In the annual working time column, we indicate the number of hours that this equipment will be in operation minus downtime for repairs.
8. Draw a conclusion

Table 1 – Assignment

Theoretical part

Scheduled preventive maintenance (PPR) is a set of organizational and technical measures for supervision, maintenance and all types of repairs, which are carried out periodically according to a pre-drawn up plan.

Thanks to this, premature wear of equipment is prevented, accidents are eliminated and prevented, and fire protection systems are maintained in constant operational readiness.

The preventive maintenance system includes the following types of technical repair and maintenance:

weekly maintenance,

monthly maintenance,

annual scheduled maintenance,

Annual scheduled maintenance is carried out in accordance with the annual equipment maintenance schedule.

Drawing up a PPR schedule

An annual schedule of preventative maintenance, on the basis of which the need for repair personnel, materials, spare parts, and components is determined. It includes every unit subject to major and current repairs.

To draw up an annual schedule of preventive maintenance (PPR schedule), we will need standards for the frequency of equipment repairs. This data can be found in the manufacturer’s passport data, if the plant specifically regulates this, or use the “Maintenance and Repair System” reference book.

There is some equipment available. All this equipment must be included in the maintenance schedule.

Column 1 indicates the name of the equipment, as a rule, brief and understandable information about the equipment.

Column 2 – number of equipment

Column 3-4 indicates service life standards between major repairs and current ones. (See Appendix 2)

Columns 5-6 – labor intensity of one repair (see Table 2 Appendix 3) based on the list of defects.

In columns 7-8 - the dates of the last major and current repairs are indicated (we conventionally accept the month of January of the current year)

In columns 9-20, each of which corresponds to one month, the symbol indicates the type of planned repair: K - capital, T - current.

In columns 21 and 22, respectively, the annual equipment downtime for repairs and the annual working time fund are recorded.

The annual schedule of preventive maintenance of equipment can be downloaded here.

Annex 1

STANDARDS FOR THE FREQUENCY, DURATION AND LABOR-INTENSITY OF MAINTENANCE AND REPAIR

Appendix 2

How to draw up an annual maintenance schedule for electrical equipment? I will try to answer this question in detail in today’s post.

It's no secret that the main document by which electrical equipment is repaired is the annual schedule of preventive maintenance of electrical equipment, on the basis of which the need for repair personnel, materials, spare parts, and components is determined. It includes each unit subject to major and routine repairs of electrical equipment.

To draw up an annual preventive maintenance schedule (preventive maintenance schedule) for electrical equipment, we will need standards for the frequency of equipment repairs. This data can be found in the manufacturer’s passport data for electrical equipment, if the plant specifically regulates this, or use the reference book “System for Maintenance and Repair of Power Equipment.” I use the A.I. reference book. FMD 2008, therefore, further I will refer to this source.

Download the reference book A.I. Foot and mouth disease

So. Your household has a certain amount of energy equipment. All this equipment must be included in the maintenance schedule. But first, some general information about what the annual PPR schedule is.

Column 1 indicates the name of the equipment, as a rule, brief and clear information about the equipment, for example, name and type, power, manufacturer, etc. Column 2 – number according to the scheme (inventory number). I often use numbers from electrical single-line diagrams or process diagrams. Columns 3-5 indicate service life standards between major repairs and current ones. Columns 6-10 indicate the dates of the last major and current repairs. In columns 11-22, each of which corresponds to one month, the symbol indicates: K - capital, T - current. In columns 23 and 24, respectively, the annual equipment downtime for repairs and the annual working time fund are recorded. Now that we have examined the general provisions about the PPR schedule, let’s look at a specific example. Let's assume that in our electrical facilities, in building 541, we have: 1) a three-phase two-winding oil transformer (T-1 according to the diagram) 6/0.4 kV, 1000 kVA; 2) pump electric motor, asynchronous (designation according to scheme N-1), Рн=125 kW;

Step 1. We enter our equipment into the empty PPR schedule form.

Step 2. At this stage, we determine the resource standards between repairs and downtime:

a) For our transformer: open the reference book p. 205 and in the table “Standards for the frequency, duration and labor intensity of repairs of transformers and complete substations” we find a description of the equipment that is suitable for our transformer. For our power of 1000 kVA, we select the values ​​of the frequency of repairs and downtime during major and current repairs, and write them down in our schedule.

b) For an electric motor according to the same scheme - page 151 Table 7.1 (see figure).

We transfer the found standards in the tables to our PPR schedule

Step 3. For the selected electrical equipment, we need to decide on the number and type of repairs in the coming year. To do this, we need to determine the dates of the last repairs - major and current. Let's say we are making a schedule for 2011. The equipment is operational, we know the dates of repairs. For T-1, a major overhaul was carried out in January 2005, the current one in January 2008. For the N-1 pump motor, the major one is September 2009, the current one is March 2010. We enter this data into the chart.

We determine when and what types of repairs the T-1 transformer will undergo in 2011. As we know there are 8640 hours in a year. We take the found service life standard between major repairs for the T-1 transformer, 103680 hours, and divide it by the number of hours in a year, 8640 hours. We calculate 103680/8640 = 12 years. Thus, the next major overhaul should be carried out 12 years after the last major overhaul, and since the last one was in January 2005, which means the next one is planned for January 2017. For current repairs, the operating principle is the same: 25920/8640 = 3 years. The last current repair was carried out in January 2008, so 2008+3=2011. The next routine repair is in January 2011, it is for this year that we draw up a schedule, therefore, in column 8 (January) for the T-1 transformer we enter “T”.

For the electric motor we get; major repairs are carried out every 6 years and are planned for September 2015. The current one is carried out 2 times a year (every 6 months) and, according to the latest current repairs, we plan for March and September 2011. Important note: if the electrical equipment is newly installed, then all types of repairs, as a rule, “dance” from the date of commissioning of the equipment.

Our graph looks like this:

Step 4. We determine the annual downtime for repairs. For a transformer it will be equal to 8 hours, because In 2011, we planned one routine repair, and in the resource standards for routine repairs the denominator is 8 hours. For the N-1 electric motor, there will be two routine repairs in 2011; the standard downtime for routine repairs is 10 hours. We multiply 10 hours by 2 and get annual downtime equal to 20 hours. In the annual working time column, we indicate the number of hours that this equipment will be in operation minus downtime for repairs. We get the final look of our graph.

Important note: at some enterprises, power engineers in their annual production schedules, instead of the last two columns of annual downtime and annual capital, indicate only one column - “Labor intensity, man*hour”. This labor intensity is calculated by the number of pieces of equipment and the labor intensity standards for one repair. This scheme is convenient when working with contractors performing repair work.

Do not forget that repair dates must be coordinated with the mechanical service and, if necessary, the instrumentation service, as well as with other structural units directly related to the repair and maintenance of related equipment.

If you have any questions about drawing up the annual PPR schedule, ask questions, I will try, if possible, to answer them in detail.

PPR for the installation of ventilation systems is needed for repairs, reconstruction, installation of internal, external air supply and short circuit. What information does this document contain:

• Instructions on how the preparatory stage should be carried out, including filling out applications for equipment, materials, structural elements (air ducts, air supply parts);
• Locations of equipment, construction materials, special equipment;
• Methods, technological sequence of work;
• Information that promotes quality installation, reducing the amount of machine and human labor;
• Requirements for labor protection, safety, environmental, fire safety;
• PPR for installation of ventilation systems is developed in accordance with OST 36-134-86. This industry standard has remained relevant for over 30 years.

Development of PPR for ventilation and air conditioning

A project for the installation of ventilation systems is needed for enterprises under construction, operating and reconstructed. The developer must use advanced methods and technologies, guided by:

• Current state standards;
• Construction standards and rules relating to labor organization, sanitary systems, safety precautions in construction;
• Technical specifications for specific tools, mechanisms, equipment, machines;
• When developing occupational safety measures, it is necessary to take into account the specific conditions at the work site. If new installation methods and technologies not provided for by the industry standard will be used, developer materials are needed. That is, industrial air conditioners, fans, split systems may require additional documentation.

Source materials for development of PPR

PPR for installation of air conditioning and ventilation is compiled using the following materials:

• Development task;
• Drawings of structures, metal structures;
• Working and estimate documentation for part of the air conditioning and air regulation project;
• List and characteristics of the tools, equipment, machinery, transport, equipment available to the contractor;
• Work schedule. Must be discussed with the general contractor;
• Data on the supply of components of the installed system;
• Results of an inspection of a functioning or reconstructed facility with the conditions for installation at an existing enterprise;
• If the PPR is compiled by a technological and engineering organization, it must be provided with all the initial materials at least four months before the start of work. Development must be accompanied by a study of the POS and an inspection of the facility.

Composition of PPR

What is included in the complete set of documents:

• General information. The rationale for the methods used, the procedure and features of the work, and safety measures are listed.
• Stroygenplan. Sketches of the location of storage areas, diagrams of movement and installation of devices used, parts of installed systems.
• Plans of objects with applied ventilation equipment.
• Calendar plan. Labor costs, sequence of technological processes.
• Technological map for installation of the ventilation system. Installation process, including preliminary and final stages.
• Characteristics of air ducts.
• Delivery schedules for system components.
• Specifications of installation materials.
• List of tools, equipment, and special equipment used by installers.
• Calculation of labor costs and wages.
• Technical and economic characteristics of installed systems.
• Purpose of TC

The technological map for the installation of the ventilation system is drawn up on the basis of MDS 12-29.2006 (according to clause 4.2). Unlike the standard TC, it takes into account:

• Features of the facility where the installation of power supply and short circuit is carried out.
• Technical capabilities of the performer.
• The specifics of the climate control equipment used.

This allows you to choose the optimal methods for carrying out technological processes, minimize time and financial costs, improve the quality of work performed, and guarantee the safety of highly complex installations in any conditions. The technological map for air conditioning and ventilation includes a set of measures for organizing labor, allowing for the rational use of mechanization, equipment, and tools available to the contractor in compliance with safety regulations.

Maintenance of technical instructions for ventilation and air conditioning.

What sections does the technical map for ventilation consist of:

• Application area. Name of the technological process. Type (specificity) of the object for which development is being carried out.
• Organization of work. Specific instructions for equipping the technological process sites with a list of equipment and special equipment used. Schemes of auxiliary operations, requirements for waste removal. The procedure for carrying out work with a detailed description.
• Quality requirements. Incoming, operational control, acceptance of work.
• The need for material and technical resources: machines, equipment, building materials.
• OHS and safety requirements. List of measures to ensure health, fire, and environmental safety.
• Technical and economic indicators. Calculations of time and financial costs necessary for the correct implementation of the technological process.

Who can develop PPR and TC

The PPR for ventilation becomes part of the overall work project or is developed separately by the contractor who will carry out the installation. Who makes it up:

• General contractor, subcontractor. If work is carried out on the territory of an existing enterprise, coordination with the customer and the operating organization is required. The PPR is approved by the contractor, which may be a subcontractor.
• A design and technological organization that has specialists with appropriate qualifications. The document is approved by the chief engineer or other responsible person of the organization that will carry out the work.

Since the technological map is part of the set of documents included in the PPR, it is subject to similar requirements. TC can be registered with TsNIIOMTP for 5 years when the technological process is repeatedly performed at the same type of facilities.

Order the development of PPR and technical specifications for the installation of ventilation and air conditioning systems

Drawing up key governing documents requires high qualifications, knowledge of a large list of current regulatory documents and standards (there are more than 20 of them for PPR alone). Reusing a work project is permitted in rare cases, since the features and locations of each object are almost never repeated. Therefore, for a one-time installation of ventilation systems, it is better to entrust the development of documentation to a design and technological organization.

Our company offers professional preparation of PPR and TC. Why choose us:

• Compliance with all industry standards, including rules for preparing a full or reduced package of documents.
• Taking into account every feature of the facility, installed equipment, and technical equipment of the contractor.
• Strict adherence to agreed deadlines.
• Affordable prices.
• The cost and development time depend on the complexity of the project, so they are always calculated individually.
