It is important to understand that the best way to design ventilation 'with reserve' at the beginning of construction, and clearly understood to which will target this object. Otherwise moozhno encounter difficulties in redevelopment of the mass, and sometimes inability to commit such an operation. Ventilation affects many areas of knowledge - including electrical installation as well as the use of powerful fans must be careful design of wiring. The company engineers usually estimate the ability to create natural ventilation, which requires little or no cost to its content. According to sanitary regulations and standards, safety rules should ensure the absence of ventilation MPC excess of various hazardous substances in the manufacturing room. In this direction, and engineering work conducted in the drafting of the building.
