Chemical Storage Compatibility
Construction and general industry · Ver en español
Talking points
- Incompatible chemicals stored together can react violently — releasing toxic gas, generating heat, causing fire, or creating explosions even without an ignition source.
- The basic rule: acids away from bases, oxidizers away from organics and flammables, and water-reactive materials away from everything wet.
- Check Section 10 of the SDS (Stability and Reactivity) for incompatible materials. Many common products are incompatible — bleach and ammonia, acetone and hydrogen peroxide.
- Use separate secondary containment for incompatible chemicals. Spills from two incompatible chemicals sharing the same containment can create the very reaction you are trying to prevent.
- Label every storage area clearly. Color-coded systems (red for flammables, yellow for oxidizers, blue for health hazards, white for corrosives) help workers store chemicals correctly.
Ask the crew
Look at our chemical storage area — are there any incompatible chemicals stored too close together?
Standards this talk is built on
A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
