GHS hazard pictograms poster

The Globally Harmonized System (GHS) puts the same hazard pictograms on chemical labels in most countries: a black symbol in a red-bordered diamond. This poster shows all nine with what each warns of, as set out in OSHA's Hazard Communication Standard, plus the other parts of the label to read: the signal word (Danger for the more severe hazards, Warning for the less severe), the hazard statements and the precautions. The pictograms are the official artwork as OSHA publishes it; the label on the container is what counts.

How to use it

Putting the GHS hazard pictograms poster to work

1
Post it in chemical stores, at dispensing points, in labs and maintenance shops.
2
Use it in hazard communication training with a real label from your site.
3
Ask: which pictograms are on the chemicals in this area, and where is the safety data sheet?
4
Pair it with the free chemical inventory and SDS register.

Which size to print

24 x 36 in or A2: a main wall or team board, read from a few metres away.
18 x 24 in or A3: a station or notice board. The A3 file also fits 11 x 17 in paper.
Letter or A4: a clipboard, binder or handout, on any office printer.

Every PDF is vector, so it stays sharp at full size. Nothing runs to the edge of the page, so no bleed is needed.

Sources and notes

The pictograms on this poster are the official GHS artwork, taken unchanged from the files OSHA publishes for the Hazard Communication Standard; they are not redrawn. The full official chart is on OSHA's pictogram page and in the UN GHS, Annex 1. In the US, the environment pictogram is not required by OSHA's Hazard Communication Standard; elsewhere it is used for chemicals that are toxic to aquatic life.
