We have been using Nitrogen in our shop as a dusting/cleaning agent for
some time now. TSSA has inspected our site and found NO infractions and our
Nitrogen cylinders are stored within our shop. We consulted experts when
designing our work space as safety is our #1 priority.
Praxair our supplier of Nitrogen gas provides this MSDS information
and yes Nitrogen is an asphyxiant but it must be present in large
quantities to cause harm. Normal fresh air exchanging in a work environment
is sufficient to eliminate any risk of asphyxiation due to exposure, in our
shop we also have a HRV that recovers heat/cooling from exhaust air while
introducing 100% fresh air into our environment, exhaust and intake air are
never mixed.
Your local supplier of compressed gasses will have on hand MSDS information
and we recommend WHMIS training to anyone considering the handling of any
dangerous materials, training IS MANDATORY in our shop.
