PP 04/19Odorization of Atmospheric Gases

Odorization has been used for many years in fuel gases and its success as a warning indicator is linked to the fact that its presence in air is always an indication of a hazardous situation. Fuel gases can only be admitted safely to the atmosphere if it is a component in a combustion process, and this process destroys the odorant.

Following serious incidents in nitrogen atmosphere in confined spaces or burn injuries in an oxygen enriched atmosphere, odorization of atmospheric gases is considered by some users. In response to this, EIGA has developed this Position Paper.

The Position Paper makes a number of recommendations for those users who could be considering the odorization of atmospheric gases.
