Compatible Chemical Families
Storing chemicals in alphabetical order can result in incompatible neighbors.
For example, barium peroxide and benzaldehyde
react violently
together and should not be stored near each other. Chemicals
should be
stored in compatible chemical families. See pages 730–732 for details on the
Flinn Suggested Chemical Storage Pattern.
