Guide Tunnelling (Australia): Sources and Control Measures - Atmospheric Contaminants Mobile App
Atmospheric contamination in tunnelling work can occur because:
How does it work?
excavations can be a receptacle for gases and fumes heavier than air, gases and fumes like methane, sulphur dioxide, carbon monoxide and carbon dioxide leak from gas bottles, fuel tanks, sewers, drains, gas pipes and LPG tanks into the tunnel particularly when other work is taking place nearby , oxygen in a non-ventilated area can be depleted due to internal combustion plants, oxidation or other natural processes, and through blasting activities. The ventilation requirements should be determined through a risk assessment. Due to the nature of tunnelling work, contaminants generated in one area of the tunnel will move readily to other areas. Protection against airborne hazards should be provided to workers. Control measures should be implemented to eliminate or minimise, so far as is reasonably practicable, the risks associated with atmospheric contaminants. The Guide Tunnelling (Australia): Sources and Control Measures for Atmospheric Contaminants mobile app includes sources and control measures - atmospheric contaminants.
