Store solvent based chemicals or polymers in the proper cabinets.

The cabinets marked with a "S" are intended for the storage of solvents and the cabinets marked with a "P" are for polymer based materials such as photoresists. When storing chemicals in these cabinets, ensure that the bottle is clean on the outside and that the lid is tight and secure to prevent leakage of vapors or liquids. Users that store chemicals in these cabinets or elsewhere in the cleanroom, make a note of it in a convenient location, such as a notebook, so that it can be found again later. If you do not need the chemical, dispose of it as necessary. If you are unsure about how to dispose of the chemical, find a member of the technical staff for assistance.
