☣️ Chemical storage compatibility & segregation checker

Tick the hazard-class storage groups you keep on site and get a compatibility matrix for every pair, a printable storage-zone plan and the key rules per zone. Works on hazard classes / storage groups — not individual product names. Exports to Word.

Which hazard-class groups do you store?

Tick each storage group present at the site. Classify each product first with its SDS Section 2 if you are unsure which group it belongs to.

Classify each product first

Segregation works on hazard classes, but you must know each product's class to place it. Decode its label and SDS Section 2 with the GHS code decoder, then build a product risk profile with the chemical risk tool. For individual chemical-to-chemical reactivity (named substances), use a dedicated reactivity database such as CAMEO Chemicals — this checker stays at the storage-group level.

⚠️ Segregation by hazard class is a planning aid, not a substitute for product-specific checks. Always read each product's SDS — Section 7 (handling & storage) and Section 10 (stability & reactivity / incompatible materials) — and follow your local fire code and dangerous-goods rules (e.g. NFPA, IFC, GHS/GSO, EU CLP, national regulations). Some products within a class have extra incompatibilities; quantities, packaging and ventilation also matter. Have a competent person review the storage layout before relying on it.
