Title Protection from silo gas
Bibliographic information Jan. 1982, Vol.25, No.1, p.89-105. Illus. 10 ref.
Abstract The composition and concentration of gases present during the filling or opening of > 70 silos were determined and simulation experiments were conducted to evaluate the influence of hatch cover position, silo contents and the outside wind conditions on the outflow of gas. Average carbon dioxide concentrations found were 35% with maize, 30% with grass and 38% with forage cereals. Nitrogen oxides were present at 20 and 25ppm with maize and grass respectively. Silos should not be entered without ventilation and blowers, and flaps are recommended to reduce gas concentrations and prevent accidents.
