Chemical compatibility must be managed in any laboratory activity in which chemicals are handled, used or stored.  The mixing of incompatible chemicals can result in sudden, violent and unforeseen hazards and may cause significant personal injury and property damage.

The Safety Data Sheet (SDS) should always be referred to first before using or storing any chemicals.  In addition, charts like the following can be used as reference guides to determine which classes of chemicals may or may not be used or stored together.

If you have any questions about the OSHA Lab Standard or lab safety in general, please consult with one of our Lab Safety Coordinators.
