Fume hood design definitions
Flammable and corrosive material storage cabinets: flammable and corrosice cabinets typically comprise the botton supporting structure of the fume hood. Tjey can be vented or non-vented enclosures used primarily for storage of flammable or corrosive materials. If vented, the flammable storage cabinet is connected to the hood exhuast.
Alarms, sensors, controls, and guages: Many of the newer VAV hoods are installed with alarms, sensors, controls and gauges. These features are incuded to provide lab personnel with a constant reading of fume hood performance. If the face velocity falls below an acceptable range the hood sensors will trigger an alarm to notify lab personnel. Low velocity alarms activate when the sash has been raised to a height at which the hood can no longer exhaust a sufficient amount of air, the building air exhaust system is not working properly, or there has been a power outage. When a low velocity alarm is activated, no hazardous chemical work should be performed until the exhaust volume is increased. Additionally, laboratory workers shold bot attempt to stop or disable hood alARMS. NU's Physical Plant should be notified for adjustment of air handling system exhaust and fume hood maintenance.
A walk-in hood is a hood which sits directly on the floor and is characterized by a very tall and deep chamber that can accommodate large pieces of equipment. Walk-in hoods may be designed as conventional, bypass, auxiliary air, or VAV. If you have a walk-in hood, contact MODULAR for operating protocol and inspection procedures.
Canopy hoods are horizontal enclosures having an open central duct suspended above a work bench or other area. Canopy hoods area most often used to exhuast areas that are too large to be enclosed within a fume hood.The major disadvantage with the canopy hood is that the contaminants are frawn directly past the user's breathing zone.
