Construction workers working in the M4 East tunnels in Sydney’s inner west were exposed to extremely high concentrations of airborne fungi. It posed a potentially “high risk to all persons”.
Recently 500 construction workers walked off the site after the findings were revealed. They had failed to receive adequate assurances from the contractor building the tunnels.
A confidential report by a Mycolab laboratory found the average of 4 samples taken from inside the tunnels had an “extremely high” rating of airborne fungal concentrations.The concentration found was significantly higher than outdoor airbourne fungal concentrations, which may pose a health risk to everyone present and particularly to sensitised individuals.
Construction staff and electricians refused to enter the tunnels until steps were taken to safeguard their health, walking off the site.
