GHS hazard symbols: a buyer’s quick guide
What the diamond pictograms on chemical labels and SDS Section 2 mean - and how to use them when you order and store materials.
The Globally Harmonised System (GHS) uses standard pictograms so hazards are recognisable worldwide. You will see them on labels and in Section 2 of the SDS.
Common pictograms
- Flame - flammable liquids, solids, or gases (e.g. acetone, IPA).
- Flame over circle - oxidisers that can intensify fire.
- Corrosion - skin/eye damage or metal corrosion (acids, caustic soda).
- Skull and crossbones - acute toxicity (severe).
- Health hazard - carcinogen, mutagen, respiratory sensitiser, aspiration hazard, etc.
- Exclamation mark - irritant, skin sensitiser, or acute toxicity (lower category).
- Gas cylinder - compressed gases.
- Environment - aquatic toxicity (where required).
- Exploding bomb - explosives / self-reactives (rare in routine lab supply).
What buyers should do
- Read the SDS before ordering if you are new to the substance.
- Match storage to the hazard class (flammables cabinet, acid cabinet, etc.).

Frequently asked questions
Where do I find GHS pictograms for a product?
On the product label and in Section 2 of the GHS Safety Data Sheet (SDS). Lubechem emails the SDS with each order and lists downloads on product pages when uploaded.
Does a pictogram mean I cannot buy the chemical online?
No - many labelled chemicals ship legally with proper packaging and paperwork. Restricted materials may have pin-code or transport limits; ask us if unsure.
