    Local exhaust ventilation (LEV) is the application of an exhaust system at or near the source of contamination. If properly designed, it will be much more efficient at removing contaminants than dilution ventilation, requiring lower exhaust volumes, less make-up air, and, in many cases, lower costs.

    Industrial Extraction is the process by which harmful air contaminants are removed from the work place for the protection of employees and the environment. [1]In the UK, the Health and Safety Executive has implemented COSHH regulations to ensure all industrial workplaces protect the health of their employees via effective Local Exhaust Ventilation (LEV). [2]

  6. Fume hood - Wikipedia

    en.wikipedia.org/wiki/Fume_hood

    Fume hoods and other local exhaust devices may be smoke tested to determine if the contaminants they are designed to remove are being adequately captured and exhausted. [ 97 ] [ 13 ] : 81 Periodic fume hood inspections may also include checks on proper behavior of workers using the device to ensure that they are not exposed to hazardous ...

  7. Ventilation (architecture) - Wikipedia

    en.wikipedia.org/wiki/Ventilation_(architecture)

    Local exhaust ventilation addresses the issue of avoiding the contamination of indoor air by specific high-emission sources by capturing airborne contaminants before they are spread into the environment. This can include water vapor control, lavatory effluent control, solvent vapors from industrial processes, and dust from wood- and metal ...
