HSE Local Exhaust Ventilation (LEV) eBulletin

  • What is LEV? LEV is an engineering control used to reduce the risk of inhalation of substances hazardous to health in a workplace, such as dust, gas, mist, fume or vapour.

    Typically, these substances may cause respiratory diseases such as occupational asthma, cancer and chronic obstructive pulmonary disease (COPD).

    LEV systems perform an essential function to protect health. They must be properly designed, installed, commissioned, tested and maintained to be effective. It is essential that employers use competent LEV engineers.
