Tens of thousands of workers develop occupational diseases from breathing in dusts, fumes and many other airborne contaminants at their place of work. Dust extraction monitoring, fume extraction or local exhaust ventilation clean the air, before harmful substances are inhaled. You have to fully understand the process at work to understand the dust sources. Dust extraction units must be used according to their design and installed correctly. What about an improperly installed dust extractor that has the ‘trust’ of the employees? They can be more dangerous than no extraction! Testing with dust extraction & monitoring in mind Test the workplace environment to ascertain likely effects it can have on staff. A dust monitor can play a part. Dust monitoring and dust measurement sampling methods are used to get an accurate measurement of what could be causing a health risk to workers directly and/or indirectly exposed. Refer to the Control of Substances Hazardous to Health (COSHH) Regulations and Workplace Exposure Limits (WELs) for dusts and fibres. These make it possible for you to ascertain whether your processes are harmful and action is needed or that they are within the safe limits defined. Dust monitors must always be properly maintained and regularly calibrated.
