Mobile Extraction System
A dangerous situation in a manhole may occur when hazardous gases get into the manhole from the outside or are generated in the manhole.
Excerpt from the special edition issued by the professional association:
Gas-related hazards in manholes
In order to eliminate gas-related hazards in manholes, preventive measures have to be taken before the manhole is entered. A recommended safety measure is the application of high-capacity fans. In the field, this kind of extraction is applied at the deepest point of the manhole. "Extraction of air = 4 x volume of the manhole".
