CAPABILITIES / VERSION HISTORY

Every revision on file, automatically numbered

An SDS is a controlled document: when it changes, the old version doesn't vanish — it gets superseded, on the record. SDS HQ keeps every prior revision of each sheet you author, numbers revisions automatically, and shows what changed between them.

Why it matters for compliance

The rule

OSHA HazCom, 29 CFR 1910.1200(g)(5) — when significant new hazard information comes to light, the SDS must be updated within three months. An audit asks two things: is the current sheet right, and can you show what it said before. Version history answers the second.

How SDS HQ does it

  • Automatic revision numbering — publishing a change increments the revision; no hand-managed "final_v3 (2).pdf".
  • Prior versions stay on file — review any superseded revision of a sheet you authored, with its date.
  • Frozen at publish — a published sheet renders from the snapshot taken when it was issued, stamped with the engine version that produced it.
  • Drift flagged — the library re-checks published sheets against the current engine and flags any whose classification would now differ; one click reopens it to refresh and re-publish.
