This is a table of chemical storage code colors, as devised by J. T. Baker. These are the standard color codes in the chemical industry. Except for the stripe code, chemicals assigned a color code generally may be stored safely with other chemicals with the same code. However, there are many exceptions, so it is important to be familiar with the safety requirements for every chemical in your inventory.
