What Premises Are Equipped With Separate Systems Of Supply And Exhaust Ventilation
The ventilation of the production premises is a system, the main purpose of which is to organize and maintain a stable air exchange inside the building. The need for ventilation is due to the fact that the equipment works inside and various production processes are implemented. All this in turn leads to the fact that suspended particles and poisonous evaporation often fall into the air. Even "innocent" production waste, which in small doses do not lead to negative consequences, in the case of high concentrations can cause employee poisoning due to air pollution.
An additional incentive for the owner to arrange the ventilation system is the fact that the lack of fresh air can lead to a decrease in labor productivity of workers, and therefore, to a smaller volume of production. To prevent this, at the stage of development of the project of the room in it, ventilation system should be provided.
Functions and appointment of ventilation in industrial premises
Most often, the premises are equipped with separate supply and exhaust ventilation systems. It consists of two parts: the first (intake) provides a tide of fresh air from the outside to the room, the second (exhaust) removes the exhaust air from the room beyond its limits. The capacity of such systems is selected by specialists, depending on the area and volumes of the room, the magnitude of harmful emissions, the number of employees being inside and equipment.
Most often, the ventilation system is one for the entire premises, but sometimes for different premises its own ventilation is equipped. In what cases is it justified?
The difference in sanitary requirements for various production rooms. For example, in research laboratories, air purity should be higher than in production shops, therefore, for it, a separate system should be organized.
The ban on mixing various exhausts and pollution due to joining hazardous reactions is relevant for enterprises of the chemical and pharmaceutical industries, when the interaction of exhausts can lead to a fire or an explosion.
Technological features - for example, for the production of some foods need cool air, and therefore, in these shops, a special system should be installed, making an emphasis on the supply part.
In any case, the premises are equipped with separate systems of supply and exhaust ventilation, guided primarily by the principles of security, compliance with technological requirements and reduce costs for systems. The last criterion is important, with him it is necessary to be considered, but the requirements specified in the sanitary standards are priority.
