An engineering company based in Leicester, who operate a manufacturing process involving metal working machinery, contacted Impact over a solution to control oil mist. Workers operate two Hurco CNC machines, seven HASS CNC machines, an open lathe, a XYZ Machine 6 and a XYZ Proturn SCX 555, all of which produce oil mist. Health implications as a result of oil mist include bronchitis, lipoid pneumonia, lung fibrosis and lung cancer.
Impact began with installing the extraction fan which would supply the movement of air needed for extraction, the fan used was a RV-50-C2 mounted on the ground. The fan was fitted with a silenced discharge duct and weather bend to extract and discharge the contaminated air to the atmosphere. Within the workshop each individual CNC machine was fitted with a be-spoke connection spigot to allow it to be safely and easily connected to the ducted system. The ducting was installed within the HSG258 – controlling airborne contaminants guidelines. For the open Lathe machine, an RFF extraction arm was installed due to its versatile abilities.
Once installed, the system was commissioned which involved; fan vibration testing, fan noise testing and duct flow measurements. Once LEV testing had been completed, Impact provided the company with a comprehensive LEV commissioning report which should be used as a benchmark for future LEV thorough examinations.
