Natural Ventilation Decreases Risk of Barn Fire

Attached are articles about something that we see all too often – another barn fire. I probably read somewhere between 10 and 20 articles every year about these tragedies. In virtually every one, there is no specific origin given for the fire or “it’s under investigation.” However, any person who has been around barns is aware of the probable answer. Usually, some electrical condition (light fixtures, heater, faulty fan, etc) ignites a flammable material such as hay, bedding, cobwebs, etc.

In the article about a tragic barn fire in Georgia that took the lives of 35 horses, it does not mention the origin of the fire but states, “The stable was filled with hay and wood chips for the horses’ bedding…. And those running the stable kept fans blowing on the horses to keep them cool through the summer night.”

Once again the issue comes down to ventilation, the use of fans, and the probable culprit of faulty wiring.

Please excuse me if I preach once again about the importance of “natural” ventilation, which in my opinion is the most critical aspect of barn design in relation to the health and safety of the animals.  “Natural” lighting is also important, but when designed effectively, both work together to ventilate the barn. I am not familiar with the barn that burned or the conditions that may have caused the fire, but the article states that the fans blowing in the barn increased the intensity of the fire.

For thirty years, we have designed barns that incorporate the chimney effect and the Bernoulli principle to ventilate barns naturally.  (Click here for explanation and to learn more).  Neither of these will eliminate the use of fans entirely in a barn, but they will greatly reduce the need for electric fans (and electric lights as well). Reducing the need, will reduce the use and consequently extend the life (they won’t wear out as quickly) of the fans or lights. Ultimately, this will also reduce energy cost for the barn. Many farms use the cheap residential box fan for ventilation over extended periods of time.  Not only are they cheaply made (I have seen them selling for as little as $10), but they are not designed to withstand the environmental abuse they can receive in the barn. Dust, dirt, hay, and/or bedding particles can clog the fans, easily creating potential for fire. In addition, the humidity can cause the fans to rust and deteriorate more rapidly. The less fans, lights, and other mechanical systems are needed, the safer the farm will be.

Although, these methods do not eliminate the possibility of one of these horrific events, they decrease the likelihood. Something that will make most, if not all, horse owners’ sleep a little more soundly at night. A well-designed barn needs to consider the heath and safety of the horse at every turn. Remember your barn does not have to cost you an arm and a leg, but neither should your barn cost you your horse.

Check out my new book, Healthy Stables by Design, at www.healthystablesbydesign.com. Not only does it discuss ventilation practices, but it will also feature other ways to make a stable safe and healthy for horses.
