Guidelines for care & Use of Dry Solvent Stills [Example]

In addition to the guidance listed above, the following storage rules should be followed in all labs:
� Water reactive chemicals (i.e. sodium metal, lithium aluminum hydride, etc.) should not be stored
near a source of water, such as faucets, sinks, fire sprinklers, safety showers, etc.
� Corrosive chemicals (i.e., mineral acids) should not be stored above shoulder level on lab benches. It
is not a good idea to store any chemical on high shelves, out of comfortable reach.
� Make certain that all bottles of chemicals are labeled
� Attempt to segregate chemicals into definite areas of storage as outlined above and return them there
when finished with them.
� When tempted to store chemicals in hoods, remember that the cabinets beneath are vented and will
serve just as well, leaving you with a safer work area in the hood.
� Do not store highly volatile, flammable chemicals in a refrigerator unless it contains a spark proof
thermostat (i.e., unless it is an explosion proof refrigerator!)
� Periodically check the chemicals in your laboratory to make certain they are tightly capped! Prolonged
storage often results in caps gradually working loose. Parafilm can be used in some cases to further airlock
the container.
� Store lecture bottles of compressed gases in the bottom vented cabinets of research lab hoods.
