Polo Citrus turned on during crushing - Footage from a 3 min video
“Over the past 12 months, 344 people were reported to have been diagnosed with an asbestos related disease and more than 100 with silicosis. Where workplace exposure is the cause, I want these numbers to head towards zero.” said Minister for Better Regulation and Innovation Kevin Anderson
Consequently, new laws have been passed by the NSW government regarding dust exposure.
Regulatory bodies including local councils, EPA and WorkSafe Australia are targeting construction and mining to ensure that the new legislation for dust control is being implemented. The EPA continued their ‘Bust the Dust’ campaign in Spring this year. ‘Operation Bust the Dust involves frequent inspections of mines on hot, dry and windy days, to check that extra controls are in place at the mines to minimise dust.’
The EPA have fined some businesses $15000-$30000 for dust pollution related offences in 2019 and 2020. Local Governments in some areas have task forces to ensure minimal impact to the community from construction. They have the power to issue Direction notices and on the spot fines. Protecting the local communities and ensuring the work can continue and is not stopped by complaints is an essential part of working successfully in built up areas.
Can you afford not to control dust on your site?
THE IMPORTANCE OF USING THE RIGHT DUST SUPPRESSION
Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing.’
That is quite a dramatic quote, but the reality is exposure to dusts in the construction and mining industries can cause serious problems, hence the current legislation and regulation changes. It is well known that it can be short term, causing vision hazards onsite and respirable problems or long-term causing irreversible lung damage.

MOBILE CRUSHING in a SYDNEY INDUSTRIAL AREA
Our case study was conducted on an Industrial site in Wetherill Park, the day was a warm 25C with the wind picking up in the afternoon. The contractor Sydney Crushing and Screening had at least 3000 tonnes of concrete, comprising of industrial building slab and footings which needed to be recycled. The concrete required significant preparation work through pulverising to break it down into smaller pieces. These were then fed by excavator into The Keestrack R3 recirc Impact Crusher with magnets and belt scales. The R3 handled the product really well and crushed it down to a -60mm product, however, a significant by-product of this process was large amounts of airborne dust.
The Mobile Polo Citrus Dust Suppression unit was commissioned in under half an hour, which included driving the trailer into position, fitting the water to the trailer and attaching the spray bar to the hopper of the crusher. The air compressor was started and the remote was used to start the mixing chambers to produce the foam. The water pressure and the Polo Citrus solution was adjusted to produce the most effective shaving cream like consistency.
A dust monitor was used to conduct real time monitoring to measure the dust levels in the crushing area. It must be noted that we have no environmental science qualifications, and this case study was conducted following TSI Dustrak guidelines. Any deductions and inferences made as a result of this dust monitoring should be retested and followed up by qualified scientists in this field, for further explanations on Dust please take a look at our eBook. Further definitions of PM (Particulate matter) can be found on the EPA website.
