3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
fine chemical enterprise
factory that produces high-value-added and technology-intensive fine chemical products with specific functions, for specific uses, in small batches and multiple varieties, from primary or secondary chemicals and biomass materials produced in the basic chemical industry as initial feedstock through deep processing
[Source: GB 51283-2020, 2.0.1]
3.2
acute toxicity
acute harmful effects arising from a single dose of the substance administered orally or transdermally or multiple doses administered within 24h, or a 4h inhalation exposure
[Source: GB 30000.18-2013, 3.1]
Note: Based on the acute toxicity estimate (ATE), acute toxicity is classified into 5 classes (Class 1 to Class 5), with Class 1 representing the highest toxicity level.
3.3
flammable gas
flammable gas or vapor formed after gasification of Class A gas or Classes A and BA flammable liquids, which is also known as combustible gas
[Source: GB/T 50493-2019, 2.0.1]
3.4
toxic gas
toxic gas or vapor that, through skin contact or inhalation during occupational activities, can cause death or permanent health damage to workers
[Source: GB/T 50493-2019, 2.0.2]
3.5
safety risk assessment of chemical reactions
assessment on the risks arising from reaction runaway and material decomposition
