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.
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.
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.
