This year Mideco has collaborated with the world-leading research centre, SIMTARS, to test and study the Bat Booth dust removal and collection efficiency data. SIMTARS – The Safety in Mines testing and Research Station – is a leading research facility for mining safety, accredited by NATA and IECEx, with over 30 years of industry experience.
Through testing of dust collected from our operating Bat Booth® units Mideco wanted to gather real-world data on how this technology is protecting the health of people who use it.
The test involved collecting and analysing the dust samples from Bat Booth® units currently installed at hard rock quarries in NSW and Queensland. The dust capturing equipment was placed in each operating Bat Booth® for a four-month period. Two different types of samples were removed – dust from the HEPA filters and dust collected from the inside of the units. The samples were taken in April 2019 and then in August 2019, and then forwarded to SIMTARS for independent analysis.
The table attached below demonstrates that between 24 and 38 grams of dust are removed in total each time Bat Booth® is used. This is a significant amount and multiplied by the number of shifts, days and months can lead to a massive reduction in overall dust exposure. In addition, such amount of dust permanently removed from staff’s uniforms in only 10 – 12 seconds cannot be achieved by other dust control equipment.
The test clearly shows that a serious amount of respirable dust and respirable quartz dust is being captured after each use (columns 6 and 8). This type of dust is the most dangerous to human lungs, having the ability to permanently damage the lung tissue which may lead to a range of respiratory conditions such as silicosis, pneumoconiosis and even lung cancer.
The testing further confirms a major role Bat Booth® plays in reducing the overall dust exposure in the workplace, especially for businesses where dust is an occupational health and safety issue.
