Silage

Safety tips/ Silo Gas

Safety tips/ Silo Gas

Production of silo gases is a natural phenomenon in all silages – the main gas produced during ensiling is carbon dioxide (CO2), but silages that have been produced from forages that are high in residual nitrate also produce nitric oxide (NO), which, in contact with air, is turned into the highly toxic nitrogen dioxide (NO2). Inhalation of even small quantities of nitrogen oxide/dioxide can lead to permanent scarring of the lungs, even brief exposure can be fatal.

Silo Gas is produced in the first hours and days of ensiling as the pH of the forage starts to fall. Yellow/brown in color, it has a distinct “bleach-like odor” and, when exposed to rising levels of air and moisture it can form nitric acid which is extremely corrosive.
