How CarCareTruth reports product safety

Last reviewed: 2026-05-15

CarCareTruth translates published safety data. We do not issue safety recommendations.

For every product with a manufacturer Safety Data Sheet (SDS) on file, the Safety panel on our product pages cites three sources:

  • The United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS), Rev. 9 (2021) — hazard codes (H-codes) and pictograms.
  • OSHA 29 CFR Part 1910, Subpart I — the U.S. federal Personal Protective Equipment standard, and substance- specific rules in Subpart Z.
  • The manufacturer’s SDS, Section 8, with revision date — the manufacturer’s own published statement of recommended PPE and engineering controls under 29 CFR 1910.1200.

PPE tier wording

PPE tier words (“Required,” “Recommended,” “Situational”) reflect the literal hazard codes and the ingredient chemistry disclosed in Section 3 of the SDS. They are not opinions. Where the SDS contains conditional language (e.g. “when ventilation is inadequate,” “during prolonged contact”), the tier is “Situational” and the trigger is named.

Where the manufacturer’s SDS Section 8 is empty or contains generic boilerplate (e.g. “use only with adequate ventilation” with no specific trigger), CarCareTruth does not echo the boilerplate as a recommendation. The tier shown is derived from the hazard codes the SDS itself assigns in Section 2.

We never affirmatively state that a PPE category is “not needed.”When no recommendation appears in published sources, the chip shows an em-dash (“—”) with the note that absence does not imply “not needed” — users should consult the full SDS.

OSHA citations on a consumer site

OSHA standards apply to employers, not to consumers directly. We cite OSHA 29 CFR sections as the U.S. reference threshold for the underlying hazard class — the floor an employer must meet when their workers are exposed to the same GHS hazard. They are not advice that a consumer must meet the same standard.

Manufacturer right to respond

Manufacturers may submit corrections, an updated SDS, or a written response via our contact form. Verified corrections are published; the prior record is preserved in our internal log.
