Health workers say engineered stone workshops need to do better to prevent a deadly disease, that can cause lung scarring. 

A Ministry of Health check recommends more be done to prevent silicosis, which can happen when engineered stone dust is inhaled. 

The ministry supports more ventilation systems, and masks, to stop this. 

College of Physicians silicosis expert Alexandra Muthu told Mike Hosking there should be a better occupational health service. 

She says at the moment, everything falls between Worksafe, ACC, Te Whatu Ora, and industry.
