How long does a fume hood last?
Product efficiency improves as technology progresses. Without a doubt, a contemporary fume hood will be able to better reduce exposure to chemicals and will handle your procedures more efficiently. If your fume hood is older than ten years, it’s time to replace it.
Is a fume hood flammable?
From the factory, there is no spark potential on the inside of a standard chemical fume hood. Combine this with a continuous stream of clean room air, and there is very little chance of flammable combustion inside a chemical fume hood.

In general, a standard fume hood can be plugged into a 120-volt outlet while accommodations can be made for 240-volt outlets.
Do fume hoods prevent fires?
Fume hoods exhaust toxic, flammable, noxious, or hazardous fumes and vapors by capturing, diluting, and removing these materials.
Fume hoods also provide physical protection against fire, spills, and explosions. Laboratory fume hoods only protect users when they are used properly and are working correctly.
How much airflow does a fume hood need?
Average air velocity at the hood face must be at least 80 linear feet per minute (fpm), with a minimum of 60 fpm at any measured point.
If regulated carcinogens are to be used, an average air velocity of 100 fpm should be maintained with a minimum of 80 fpm at any measured point.
