LEV Testing

Local exhaust ventilation (LEV) is any system which removes dust, fumes, vapours or any airborne contaminants which may cause occupational health issues to your staff.


Under legislation employers are required to ensure that their employee’s exposure to any hazardous substances are removed where possible or controlled at source to reduce exposure. Adverse health effects can occur due to exposure to harmful or carcinogenic materials, but also to more benign contaminants where simple frequency and duration of contact can lead to serious health impacts.


The employer has a legal and ethical responsibility to ensure there LEV system is operating correctly and providing adequate protection to their employees.
