The maintenance and repair log of the ventilation system is one of the necessary documents along with the Passport of the ventilation unit and the Operation log. All measures for the repair and maintenance of ventilation systems are recorded in the journal. It is he who is the main regulatory document.
The design of the magazine is carried out by specialists who carry out the work. A preliminary contract for the maintenance of the ventilation system is concluded between him and the company. They draw up an Act of technical condition, which indicates the main parameters of the system and its condition at the time of the survey.
Based on the Act, recommendations are drawn up for the maintenance of supply and exhaust ventilation.

Security measures
compulsory compliance with security measures Maintenance of ventilation is carried out strictly according to the approved schedule, coordinated with the operating mode of the enterprise and the recommendations of the equipment manufacturer.
- The equipment is started and stopped in a certain sequence, which ensures the complete removal of harmful substances from the premises and air ducts.
- The guide assemblies on the fans are checked once every 4 weeks.
- Air heaters are checked for leaks every 10 days.
- If, during maintenance of cell oil filters, it is found that their resistance increases by ½ or the dust content in the oil reaches 0.16 kilograms per liter, the oil should be changed, and the filter surfaces should be rinsed with 10% caustic solution.
- It is necessary to check the clogging of the ventilation grids and grids at least once every 3 months.
- During servicing of the ventilation system sound attenuators, the integrity of all components, the tightness and the tightness of the structure should be checked. If the sound-absorbing material has collapsed, the missing pieces must be restored.

Is it possible to obtain a license for the maintenance of existing ventilation systems by a specialist within the enterprise and under what conditions?
If I understand correctly, you do not need a license. It is needed if you will work and maintain a fire (smoke) ventilation system. In this case, it is impractical to do this, it is easier and cheaper to find a contractor.
Good day!
Please tell me if there are any regulatory documents obliging the organization to have a separate contract for ventilation maintenance for reporting to the supervisory authorities (fire supervision, Rospotrebnadzor)?
Those. are you required to have a service contract? Of course not.
When checking, the ventilation system must be in the required technical condition, that's what you need.
Please tell me. Management Company. Two employees have Minarhstroy certificates (a specialist responsible for the safe operation of gas facilities (housing stock) and the second who passed the exam on knowledge of the rules for the production of pipe and furnace work and is admitted to work on the maintenance of chimneys and ventilation ducts). The house is not equipped with gas stoves. Is the ventilation system a fire extinguishing and smoke removal system and is an EMERCOM license needed to check ventilation ducts in this case? If possible with links to articles.Thanks
Hello.Unfortunately, your question is highly specialized and we cannot answer it reliably, so as not to expose you and your employees to risks and fines.
Yes, a license from the Ministry of Emergencies is needed. It is spelled out in the 410 government decree. If memory serves.
Good day.
What documentation for the ventilation system should be at the meat processing plant.
Thank you.
