Everything Fume Hoods

Supporting Fume Hood Safety

The more you know about fume hoods, laboratory ventilation systems and how they work; the safer you will be.  Laboratories are dangerous places and our goal is to help make them safer.

Is your Fume Hood Working?

Just because we hear the blower running, feel air movement, or even see a correct face velocity on the hood alarm, that doesn’t mean it is working.

The purpose of the fume hood is to capture, contain, dulite, and exhaust. When a hood fails to work properly, there is loss of containment.

This loss of containment allows fugitive contaminants escape into the lab. Creating possible harmful air. Exposure to these contaminants can be unhealthy.

Are these hoods working? From the glass and the corrosion, you can there are problems.  But what is the problem?

Based on the damage to the hood itself, what impact do you think this loss of containment is having on the users?


Home Section 3

What you can’t see might be harming you. When you smell chemicals and see rust and corrosion you must assume that there is a loss of containment and high concentrations of chemicals are in the air.

Depending on the chemical, this exposure could be taking away years of your lifespan.  Exposing your body to bad air can’t be good.

Every lab is different, every Laboratory Ventilation System is different,  so the exact same hood will perform differently in different labs.

The fume hood only functions properly when connected to a well designed and maintained laboratory ventilation system.  The only way to know if your hood is safe is to do containment testing.

Fume Hoods should be tested regularly.  Your life may depend on it.
