We have benchtop fixed speed hoods at all the benches (24) as well as two large variable speed fume hoods on the sides.� I like having some ventilation right where the students are working.� We put reagents and waste in the large hoods.� This is our freshman labs and we don't need students working in large fume hoods.� In our organic labs there are 9 8 foot hoods so every student works in a hood (2 students per hood).�

Think about a balance room. We have ours as the separation between two rooms.� There are glass panels in the walls on the end of the labs so that we can see what is going on in that room from the labs.� We have computers, balances, a large cabinet for Vernier units, and refrigerators in these areas.�

Don't forget distilled water.� We only have it at the two main sinks (not at every student sink).� Something that I regret every day is that we do not have any high faucets for washing burets.� Don't forget that.� In our old building, the low faucet would swing over opening a valve for the higher one.� That was great.�

I would also have loved to have an opening at each work area where a swing stool could have been installed - it pulls out when in use and is out of the way otherwise.� We have free standing stools in the labs, and I hate them - they are always getting in the way.� So if you are going to let the students sit, think about this.

Make sure you find out from your local fire code how many people your space can accommodate (including instructor and TA).� This has to to do with square footage and exits (I think).� Design the maximum work areas for that. �

In addition to having enough power for all the equipment, think about the placement of the the outlets.� Ours are right behind the sinks.� While they are ground faulted, it seems to me that they should be up off the counter.

Do you have a hood in the room already?

We are in the planning stages for a remodel of an existing engineering lab into a chemistry undergraduate research laboratory. How should the room be outfitted in terms of chemical safety considerations?

We are thinking

-� � � � � � � � � ABC Fire extinguisher (do we need a D?)

-� � � � � � � � � Eyewash stations at each sink

-� � � � � � � � � Shower just outside the door (already in place)

-� � � � � � � � � First aid box on wall

-� � � � � � � � � Fire blanket

What are we missing?
