Toxic gases – Gases which: are known to be so toxic or corrosive to humans as to pose a hazard to health; or; are presumed to be toxic or corrosive to humans because they have an LC 50 value equal to or less than 5000 ml/m 3 (ppm). e.g. hydrogen cyanide. Division 2.3
A chemical hazard symbol is a pictogram applied to containers and storage areas of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for transportation, containers for end-use, or on a vehicle during transportation.
Also, harmful chemicals and irritants are marked with an exclamation mark, replacing the European saltire. Pictograms will have a black symbol on a white background with a red diamond frame. For transport, pictograms will have the background, symbol and colors currently used in the UN Recommendations on the Transport of Dangerous Goods.
