A gas cabinet is a metallic enclosure which is used to provide local exhaust ventilation system for virtually all of the gases used or generated in the semiconductor, solar, MEMS, NANO, solar PV, manufacturing and other advanced technologies. [1]
[2]: 11–12 For general exhaust ventilation in laboratories, a nonrecirculating system is used with 4–12 air changes per hour when used in tandem with local exhaust ventilation, and sources of contamination are placed close to the air exhaust and downwind of workers, and away from windows or doors that may cause air drafts.

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 ...

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 ...

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).
