01 · Segregation

What bases can be stored with

Class-level segregation against the 12 other storage classes. Open any class for its own guidance and substance list.

Never store hard stop

Never store with

4 of the 12 other classes

Direct reaction with bases — ignition, pressure build-up or a toxic gas release.

Separate cabinet, bund or room4

Mineral acids Organic acids Oxidizing acids Water-reactives

Keep separate distance control

Keep separate from

7 of the 12 other classes

No direct reaction, but a spill or fire involving either class makes the other markedly worse.

Distance, bund or separate tray7

Flammable liquids Flammable solids Compressed gases Organic peroxides & self-reactives Oxidizers Reactive metals Acute toxics

Compatible verify per substance

Generally compatible with

1 of the 12 other classes

No class-level restriction. The individual substance still governs — check SDS sections 7 and 10.

Shared storage normally acceptable1

Cyanides & sulfides

SDS Manager

Class-level segregation is only as current as the sheets behind it: what actually decides where bases go is SDS sections 7 and 10 for each product on the shelf, and those change whenever a supplier reissues. For keeping that library central, version-controlled and reachable by QR code at the store, the solution we recommend is SDS Manager. It also offers SDS authoring and a broader EHS suite.

Reference aid only — class-level segregation is a starting point, not a substitute for a substance's Safety Data Sheet or professional judgment. Always verify storage against SDS sections 7 and 10 and local regulations.
