The creation of a carbon dioxide deficient environment is a health hazard related to silos. a true b false

True

Reason:
Silo gas is formed due to the natural fermentation of chopped silage immediately after it is placed in the Silo. Variety of gases are released during this process. The quality of silo is determined by the gases present in it.  Generally, both nitrogen and carbon dioxide gases are created in silo, but the amount of CO2 produced are in greater amounts. This is important because higher  CO2 concentration assist in maintaining superior quality silage. Thus, creation of a carbon dioxide deficient environment is a health hazard for silos.

The air is going to come out because of the low pressure.
