Safety Information
Nitrogen is an inert gas that does not support life.
Can cause rapid suffocation.

Nitrogen is mainly found in the atmosphere, where it accounts for 78 % by volume of the air we breathe. Mainly used for protect facilities and to ensure products high quality, as well as on inertization processes with the purpose of protecting the storage of raw-material or finished products in liquid form, avoiding peroxide formation and other undesirable compounds.
