EXCELLENCE IN COMPRESSED - AIR AND CONFINED SPACE VENTILATION 
 

TEMPORARY TUNNEL VENTILATION AND MONITORING 

Civil engineering work within tunnels frequently generates fumes and respirable dusts above current legislation (EH40) levels. Without some form of ventilation and monitoring, workers within tunnels can be exposed to dangerous levels of contaminants.  
 
These atmospheric hazards can be generated from a number of sources including engine exhaust gases, welding or cutting processes and the dust from handling of ballast stone. 
 
Factair has been providing a solution to this problem since 1992 with its complete tunnel ventilation service for temporary works. Wherever possible fans are deployed outside the tunnel adjacent to the portal thus causing no obstruction to traffic, or adding pollution from the generators or engines.  
 
As standard on all managed projects and also available as a managed service, Factair's engineers provide regular on site air quality testing. Not only does this ensure workers within the confined space are not exposed to contaminants exceeding statutory levels but the data is also compiled into a comprehensive report at the end of the project. Factair is RISQS approved (supplier ID 54155) with a 5 star rating. 

In addition Factair's engineers can also record noise levels within the workspace checking that suitable signage is in place and PPE is provided. These results are included in the final environmental condition report.
