Ventilation Systems on Campus
The use of ventilation systems can be an effective engineering control in an effort to control exposures along the path to the worker. This method can be used to control worker exposure to various types of dust, aerosols, vapours, gases, and fumes.
All buildings at Carleton University are mechanically ventilated and controlled from a centralized location. Mechanical ventilation used for worker exposure control can either be in the form of a general ventilation system (i.e., room) or a local exhaust system.
Local Exhaust Ventilation (LEV)
The various types of local exhaust systems used on campus range from standard fume hoods and biological safety cabinets to a wide variety of elephant arms/snorkels and specialized hoods.
Properly functioning local exhaust systems help to control worker exposure to hazardous materials and as such it is critical to ensure that not only are they operating as intended but that all users know and understand how to safely use their equipment.
