Workplace ventilation, air contaminants, is performed to check for. For this reason, and to create a healthy and safe working environment smoke, dust and contaminants such as vapor to get away from the current environment is used.
Ventilation systems the air by moving a certain speed and a certain amount of unwanted pollutants (or “exhaust”) are designed to eliminate. Ventilation systems are all basically followed the same principles; however, for each workplace, the type of work and the rate of pollutants in the workplace, according to the design of the system should be made separate.
Ventilation systems
Continuous fresh air to provide continuous renewal of the ambient air
Keeping the comfort level temperature and humidity
Reduction of fire and explosion hazards
Eliminating or diluting pollutants
To prevent the formation of undesirable air currents in the environment (e.g., the spread of the stench), and in many cases environments or outside air of the environment against negative pressure (vacuum vent) or positive pressure (ventilation) are targeted to ensure that they are kept under.
