Safety warning words for hazardous goods
Thread Content
I don’t know if such a substance exists – a substance that is a flammable liquid with a medium flash point but is also highly toxic. If it does exist, should it be labeled as dangerous or as a warning, in accordance with the safety warnings for hazardous goods? I seek advice from experts and would like to see some supporting evidence.
Table 1: Correspondence between hazard words and hazard categories
Hazard Word | Chemical Hazard Category
--- | ---
Danger | Explosives, flammable gases, toxic gases, liquids with low flash point, substances that are highly flammable on their own, substances that become flammable when exposed to moisture, strong oxidizing agents, organic peroxides, highly toxic substances, strong acidic corrosive substances
Warning | Non-flammable gases, liquids with medium flash point, flammable solids of category 1, substances that are flammable on their own but to a lesser extent, substances that become flammable when exposed to moisture, oxidizing agents of category 2, toxic substances, acidic corrosive substances of category 2, alkaline corrosive substances of category 1
Caution | Liquids with high flash point, flammable solids of category 2, harmful substances, alkaline corrosive substances of category 2, other corrosive substances

I know that highly toxic substances require a hazard label, while those with a flash point at or above 60°C need a warning label. What I want to ask is: when both of these characteristics are present, should the label be upgraded from a warning to a hazard label?
Of course, it has to be handled in accordance with the highest standards. For substances like the one you mentioned, do you treat them more as highly toxic poisons, or as liquids with a moderate flash point?
Thank you, I’ve found the basis for it. In accordance with the provisions on warning words in 4.2.2 of GB15258－1999, when a chemical possesses two or more hazards, the warning word corresponding to the most severe hazard shall be used.
