Local Exhaust Ventilation Testing

Effective control of airborne contaminants is essential to safeguarding worker health and ensuring regulatory compliance. IOM’s Local Exhaust Ventilation (LEV) services are designed to help organisations proactively manage exposure risks and maintain a healthy, productive workforce. 

LEV systems serve as an important engineering control against harmful airborne substances such as dust, fumes, vapours, and mist. By capturing contaminants at their source, LEV systems significantly reduce the risk of respiratory illnesses including asthma and chronic obstructive pulmonary disease (COPD).  

Under the Control of Substances Hazardous to Health (COSHH) regulations, most LEV systems must be thoroughly examined and tested at least every 14 months. Ensuring that they are fit for purpose and properly maintained. Failure to comply can result in legal penalties and have the potential to escalate into lawsuits. 

IOM removes the stress, making sure that your systems are not only compliant but are positioned to be as effective as possible. Reducing contaminants and keeping the workforce safe and healthy. 

Common uses for LEVs 

LEV’s are needed in a wide range of industries as the hazards are many and varied. Below is a small sample of where IOM has been able to conduct validations and verifications to reduce airborne hazards. 

• Manufacturing – welding, grinding, and plastic processing.
• Laboratories – chemical handling and pharmaceutical compounding. 
• Woodworking – sanding, cutting, and routing. 
• Food production – flour dust and spice blending. 
• Construction – silica dust from cutting and drilling. 
• Automotive & aerospace – brake servicing and composite fabrication. 
• Electronics – soldering and cleanroom operations. 
• Printing & packaging – solvent-based inks and laser cutting.
