Is your LEV System still fit for purpose?

Local Exhaust Ventilation (LEV) systems are crucial for maintaining clean and safe working environments in industries where airborne contaminants including dust, fume, mist and smoke are generated. These systems are designed to capture and remove hazardous substances at their source, preventing dispersion into the surrounding air.

Remedial works can be essential for maintaining the efficiency, safety, and regulatory compliance of all LEV systems:


  • Maintaining Performance

Over time, the components of LEV systems, such as extraction hoods, ductwork, fans, and filters, can degrade due to wear and tear. Filters may become clogged, fans may lose efficiency, and ducts might develop leaks. Adding additional extraction equipment into the system could also affect performance as the pressure in the ducting may alter.

  • Occupational Health and Safety

The primary purpose of LEV systems is to protect workers from exposure to hazardous substances. When these systems are not functioning properly, workers can be exposed to harmful airborne contaminants, leading to respiratory issues, skin irritations, or more severe health problems.

  • Regulatory Compliance

COSHH guidance dictates permissible workplace exposure limits (WELs) for various airborne contaminants. LEV systems are required to meet these standards to ensure that workplaces are safe and compliant. Failure to meet these standards can result in fines, penalties, or even legal action.

  • Energy Efficiency

An improperly functioning LEV system can consume more energy than necessary, leading to increased operational costs. Clogged filters, malfunctioning fans, or inadequate ductwork can strain the system and result in higher energy consumption.

  • Longevity and Cost-Effectiveness

Regular maintenance and remedial works can sometimes extend the operational life of LEV systems. Addressing minor issues promptly prevents them from escalating into major failures that require costly repairs or complete system replacements.
