There is no federal chemical-segregation matrix, which is why so much guidance on this topic is subtly wrong. This guide covers the one explicit rule in 1910.106(d)(7)(iv), the cabinet quantities at (d)(3)(i), the pairs that cause most facility incidents, and an eight-step segregation walk that produces findings rather than reassurance.

A facility safety checklist answers a different question from a crew checklist: not what the shift does, but what the building must provide. This walkthrough covers walking surfaces, egress, eyewash and emergency equipment, electrical, storage and signage, tags each item with its OSHA paragraph, and ends with a worked pass over one floor.

OSHA 29 CFR 1910.106 limits flammable storage cabinets to 60 gallons of Class I or II liquids and requires double-walled steel construction with self-closing doors. NFPA 30 governs local fire code compliance.
