Hydrocarbons, C1-4, sweetened hazard class and category

GHS hazard classes Hydrocarbons, C1-4… falls into
Hazard class Category From code Pictogram
Flammable gases GHS chapter 2.2 Category 1A H220 GHS02
Germ cell mutagenicity GHS chapter 3.5 Category 1A or 1B H340 GHS08
Carcinogenicity GHS chapter 3.6 Category 1A or 1B H350 GHS08

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Hydrocarbons, C1-4…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Hydrocarbons, C1-4… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements
