Airborne respirable silica has been a major issue for construction colleges for decades.
Coleg Cambria, one of the UK’s leading construction colleges with over 26,000 students; needed a solution and turned to mist-air for help.
How can mist-air help?
mist-air has developed and installed a cost-effective way to remove suspended dust from the teaching environment. This has significantly improved occupational health for students and tutors.
Fine dust on its own is detrimental to people’s health, the dust generated from construction materials often contains this harmful crystalline silica.
Crystalline silica dust has been an issue in colleges throughout Europe for many years. The dust is created during the dismantling of educational projects and the subsequent clean-up of the rubble and dust.
The fine dust that is generated stays suspended in the atmosphere for many hours; often dust will still be in the air when the next class enters the room.
Inhaling crystalline silica can result in the formation of scar tissue in the lungs, causing a disabling and incurable lung disease called silicosis.
Water but no wetting?
The mist-air systems creates a controllable micro fine fog that floats in the air.
When the ultra-fine fog encounters the dust, it adds weight to the dust particles preventing them from staying airborne.
The way the system generates the fog means that any excess fog evaporates quickly.
The mist-air system doesn’t create any wetting on floors, personnel or equipment.
Cambria's Head of Estates Rick Bedson is responsible for health and safety at the college. He said: "The mist-air dust suppression system was installed in the brickwork training facility on Coleg Cambria's Deeside site as a trial.
"It proved to be very effective, significantly reducing the level of airborne dust particles. Both staff and students were impressed with the difference the system has made.
The trial was a huge success and reports so positive that the mist-air system has now been installed in the plastering and brickwork teaching facilities at the college's Bersham site as well."
mist-air have over 45 years of experience designing bespoke dry fog systems for industrial applications; such as power stations, recycling centres, brick factories, cement works, quarries, foundries, and paper mills.
