Abstract Occupational safety and health regulations classify as enclosed areas the feed silos used in agricultural environments. Serious and often fatal accidents occur in these silage reservoirs. To take into account the risks posed by conventional tower silos, this study considered using scale models for their study. The report of this preliminary research describes how a laboratory specimen of a scale model was developed for estimating the feasibility of using such miniature versions and of modifying them as needed. By measuring gases and other parameters, the silage fermentation process was followed in this experimental structure. Based on data from prior ventilation tests on corn silage fermentation gases, the design of the scale model silo was improved.
