05 — Safety & Certifications
Safety & Certifications, Explained
GREENGUARD, BIFMA, CARB, formaldehyde, PFAS — what each one actually limits, and how to check it at the source.
This is the hub the rest of the site is built on. Certifications are the only material-safety signal a buyer can verify without a lab — but only if you know what each one actually covers and how to confirm a product carries it rather than just claiming it. These explainers define GREENGUARD Gold, BIFMA, CARB Phase 2 and TSCA Title VI in plain English, tell you where formaldehyde and PFAS actually come from in a workstation, and — the part nobody else publishes — show you how to look up any model in the certifying body's own registry. They are also where every product roundup on this site sends you to check our homework.
