Description: Some gases produced during silage making, i.e. carbon dioxide (C02), nitric oxide (NO) and nitrogen oxide (N02) are lethal when inhaled in sufficient quantities and concentrations. Freshly-made silage produces dangerous levels of these gases in confined spaces such as the silo, feed room and connecting barn. These gas hazards are not a new threat, as indicated by the number of safety bulletins issued previously on this subject. At present, no good method has been found to reduce the production of silo gases. Although a satisfactory remote gas concentration measurement system has been developed for silo gases (St. Denis and Sabourin 1984), the system has not yet been assembled and sold as a user-ready kit. Pressure-demand, remote breathing apparatuses are commercially available and are generally recommended for safe entry into confined spaces containing hazardous gases. However, the equipment is too expensive and technical for widespread use by untrained farmers. At this time, forced ventilation of the headspace remains the only practical method for farmers to deal with silo gas, although for absolute safety the effectiveness of the ventilation procedure needs confirmation. The objective of this study was to investigate improved methods of ventilating silos, considering such factors as silo diameter, headspace depth, ventilation rate and effectiveness.
