Hey Ralph - While the actual H code might not appear, aren't they the "Hazard Statement" text that is required on the labels under 1910.1200 App C (Mandatory)?å Sigma Aldrich SDSs include them.

From SA for benzene.

Classification of the substance or mixture
GHS Classification in accordance with 29 CFR 1910 (OSHA HCS)
Flammable liquids (Category 2), H225
Skin irritation (Category 2), H315
Eye irritation (Category 2A), H319
Germ cell mutagenicity (Category 1B), H340
Carcinogenicity (Category 1A), H350
Specific target organ toxicity - repeated exposure (Category 1), H372
Aspiration hazard (Category 1), H304
Acute aquatic toxicity (Category 3), H402
Chronic aquatic toxicity (Category 3), H412

Someone asked me the other day if the Hazard Statement codes (H220, etc.) are part of OSHA's HazComm standard. As far as I can tell, they aren't and US SDS's don't include them. Am I correct in this? Anyway know why they might not be included in the US?

Thanks for any help with this question.

- Ralph
