Pictogram of hazardous chemicals

 

What is a hazardous chemical? According to the "Regulations on the Safety Management of Hazardous Chemicals" in China, "highly toxic chemicals and other chemicals with toxic, corrosive, explosive, combustion, and combustion supporting properties that are harmful to human health, facilities, and the environment" are not applicable to the safety management of civilian explosives, fireworks and firecrackers, radioactive materials, nuclear energy materials, and hazardous chemicals used in national defense research and production.

 

 

 

The "Catalogue of Hazardous Chemicals" (2015 edition) lists 2828 entries, with serial number 2828 being a category entry.

 

 

 

A pictogram is a graphic representation of the hazardous properties of a hazardous product. Specific requirements: a) Border: The red color should be wide enough and eye-catching; b) Symbol: black; c) Background: White. There are a total of 9 pictograms in the Globally Harmonized System of Classification and Labelling of Chemicals.

Differences between the two

 

（1） The applicable international regulations vary. Dangerous goods are subject to the United Nations' Recommendations on the Transport of Dangerous Goods (TDG), while dangerous chemicals are subject to the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

 

（2） The biggest difference is that there are Arabic numerals at the bottom corner of the transportation label for dangerous goods, but there is no pictogram for dangerous chemicals. Take flammable gases as an example for specific analysis.
