1 Ventilation System in Tunnel during Construction Works

Preface Construction works always involve danger and their environment is not always clean. In case of tunnelling works, especially in tunnels to be constructed with the drill and blast method, the problems on the safety and health such as the ones by dust and poison gas are serious subjects. This paper discusses the principle of ventilation system in tunnel during construction to provide good ...

Mold Contamination Due to Construction Dust in Ventilation System Detected During Routine Pre-commissioning Air Sampling

Air flow disturbance by moving objects at local exhaust ventilation

The present thesis aims to study the effect of human movements on local exhaust ventilation. In its simplest terms, local exhaust ventilation is a system which has the function of extracting contaminated air situated close to the contaminant source, protecting a working person from exposure to hazardous substances by containing or capturing them locally, at the emission point. As an important s...

Preliminary Ventilation and Cooling during the Construction of the Brenner Base Tunnel

With a length of more than 55 km, the Brenner Base Tunnel (BBT) connecting Austria and Italy will be one of the world’s very long tunnels in the future. During the construction phase, climatic conditions need to be maintained fulfilling the occupational health requirements, assuring the functionality of the machinery and allowing the intended construction processes. In view of the extended cons...
