Unclassified & SDS-Confirmed Storage

Some Chemical DB records have an empty, “N/A,” or incomplete hazard class. Treat the Safety Data Sheet as the authority and use storage guidance from flammability, compatibility, and fire-suppression fields.

Class, Division, and GHS meaning

DOT class/division and GHS category strings are transport and labeling tools. When they are missing here, do not assume the material is non-hazardous—confirm classification before selecting a building.

Storage implications for rental buildings

Start with the flammable vs non-flammable flag on the chemical page, review compatibility notes, then request a rental configuration that can be adjusted once the SDS class is confirmed.
