Airborne respirable dust particles too fine to be filtered by the nasal cavity can be inhaled or breathed deep into the lungs. Long-term exposure to respirable dusts can lead to diseases ranging from bronchitis to cancer. Even if the dust is not at harmful levels it can cause irritation to the eyes and throat and increase the risk of physical injury due to poor visibility. Dust can be generated about the workplace or underground by dry roadways, bare soil or rock, vegetation removal, traffic and wind. The Guide Tunnelling (Australia): Sources and Control Measures - Dusts and Silica mobile app includes sources and control measures for dusts and silica. This app is part of a collection of Guide Tunnelling (Australia) apps. Download them all for free!

“I’m not a tech guy and I was able to pick this thing up in probably an hour, and actually start to build apps. I’ve done them over lunch when I’ve gotten frustrated with a process that didn’t exist in our company. So for non tech people who’ve got a problem, the support here is awesome and I’d recommend it to anybody, not just in our industry.”
