Explanation:

Different ways of venting fire gases

  • Fire ventilation can be performed in three different ways:
    1. horizontally
    2. vertically
    3. mechanically (with the help of fans).
  • Whichever way is most suitable depends, among other things, on how inlets (openings where fresh air flows in), outlets or exhaust openings (openings where fire gases flow out) and the fire are located in relation to each other in terms of distance and height.
  • The most appropriate way also depends on what other aids are used and other measures that are initiated.
  • Be aware that the different ways of venting have consequences of different kinds.
