The minimalist guide to safe chemical storage

Correct chemical storage is simple and straightforward, isn’t it? Some chemicals can safely share the same store; others can never do so – right? Wrong.

As with so many things in life, the answers about chemical storage aren’t completely black and white. Grey areas arise in the case of anything labelled ‘harmful’ or ‘irritant’. These two groups can share the same store only if special arrangements are made. Erring on the side of caution is probably best, so keeping them apart is probably the way forward.

To take away any uncertainty about how to store chemicals safely, we have an at-a-glance chemical compatibility storage chart you’ll find really useful. It’s an instant reference using traffic light colours to tell you at a glance which category of chemicals are suitable storage bedfellows, and which aren’t.

And in the going, we’d draw your attention to the text panel at the bottom of the chart. In summary, the message is this: If you store organic acids (like Acetic or Formic) with common mineral acids (Sulphuric and Nitric), you’re setting up the potential for fire and explosion, so don’t do it – but organic acids are generally safe to store with flammables or solvents…
