Gas Free Certification

At Control Union Spain we offer expert supervision and determination of the content of hydrogen phosphide (PH3) and oxygen in the atmosphere of ship holds, warehouses and silos.
The gas that is produced in the fumigation of agricultural products is phosphine (PH3), a colorless gas, denser than air and flammable that can produce harmful health effects when inhaled at high concentrations.

It is for this reason that our work is carried out with the most rigorous equipment and methodology. Our job is to determine that the phosphine concentration is within tolerable levels.
