Do diesel, kerosene, and space kerosene each fall under category A or category B? Could you give some advice?

Kerosene belongs to Category B A, while diesel belongs to Category B B.

Light diesel oil (GB252-2000) has a flash point of ≤55°C and belongs to Class B； Aircraft kerosene (Jet Fuel No. 3, GB6537-2006) has a flash point of ≤38°C and belongs to Class A2.

-Light diesel No. 35: Category B; Heavy diesel: Category A; Kerosene: Category A; Painting fuel: Category A. The above data are taken from Appendix 3 of GB50160-92 (1999 edition); please verify it yourself!

The fire hazard classification of oils is based on their flash point Ft (°C): 1. Ft < 28°C, Class A； 2. 28≤Ft≤45, Class B A ； 　　45 < Ft < 60, Class B ； 3. 60≤Ft≤120, Class A, Group C ； 　　120 < Ft, Class B. Furthermore, depending on the type of crude oil used by refining companies to produce finished oils, the flash points of their products such as diesel, kerosene, and aviation kerosene also vary. -35# light diesel belongs to Category A, while -30#, -20#, -10#, 0#, and 10# diesel belong to Category B. Aviation kerosene belongs to Class B.

They’re all very professional; I really have to admire that!

Light diesel fuel No. 35: Category B; Heavy diesel fuel: Category A; Kerosene: Category A; Painting fuel: Category A. The above data are taken from Appendix 3 of GB50160-92 (1999 edition); there is a contradiction with the classifications specified in the standard! 1. Ft < 28°C, Class A ； 2. 28≤Ft≤45, Class B A ； 　　45 < Ft < 60, Class B ； 3. 60≤Ft≤120, Class A, Group C ； 　　120 < Ft, Class B. How exactly should it be handled during classification?

According to the latest national standards, the flash point of diesel has been reduced, classifying it as Category B. However, safety authorities still regulate it as Category A

To be precise, aside from heavy diesel, all diesel today belongs to Category B

Appendix III of GB50160-92 (1999 edition) specifies this, but this regulation is about to be repealed; the revised version, effective from July 2009, sets out the following provisions regarding diesel: Table B.0.1 Examples of fire hazard classification for liquefied hydrocarbons and flammable liquids. Category Name Class A Liquefied chloromethane, liquefied cis-2-butene, liquefied ethylene, liquefied ethane, liquefied trans-2-butene, liquefied cyclopropane, liquefied propylene, liquefied propane, liquefied cyclobutane, liquefied neopentane, liquefied butylene, liquefied butane, liquefied vinyl chloride, liquefied ethylene oxide, liquefied butadiene, liquefied isobutane, liquefied isobutylene, liquefied petroleum gas, dimethylamine, trimethylamine, dimethyl sulfide, liquefied dimethyl ether B Isoprene, isopentane, gasoline, pentane, carbon disulfide, isohexane, hexane, petroleum ether, isooctane, cyclohexane, octane, isooctane, benzene, heptane, naphtha, crude oil, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, isobutanol, diethyl ether, acetaldehyde, epichlorohydrin, methyl formate, ethylamine, diethylamine, propanal, butyraldehyde, triethylamine, vinyl acetate, methylethyl ketone, acrylonitrile, ethyl acetate, isopropyl acetate, dichloroethylene, methanol, isopropanol, ethanol, propyl acetate, propanol, isobutyric acid, butyric acid, pyridine, dichloroethane, butyl acetate, isopentyl acetate, amyl formate, methyl methacrylate, methyl tert-butyl ether, liquid organic peroxides Class A Cumene, epichlorohydrin, styrene, jet fuel, kerosene, butanol, chlorobenzene, ethylenediamine, pentanol, glacial acetic acid, isopentanol, cumene, liquid ammonia B Light diesel, cyclopentane, ethyl silicate, chloroethanol, chloropropanol, dimethylformamide, diethylbenzene, liquid sulfur Class C Heavy diesel, aniline, spindle oil, phenol, cresol, furfural, No. 20 heavy oil, benzaldehyde, cyclohexanol, methacrylic acid, formic acid, butyl glycol ether, formaldehyde, sugar alcohols, octanol, mon ethanolamine, propylene glycol, ethylene glycol, dimethylacetamide Class B Paraffin oil, No. 100 heavy oil, residue oil, transformer oil, lubricating oil, diethylene glycol ether, triethylene glycol ether, dibutyl phthalate, glycerin, biphenyl-biphenyl ether mixture, dichloromethane, diethanolamine, triethanolamine, diethylene glycol, triethylene glycol, liquid asphalt Note: For light diesel with a flash point of less than 60°C and greater than or equal to 55°C, if the operating temperature of the storage tank is less than or equal to 40°C, its fire hazard can be considered as Class C A.
