Flammable liquid refers to a liquid with a flash point not higher than 93°C.
Flammable liquids are classified into 4 categories based on flash point:
|

Standard
|
|
1
|
Flash point ＜23℃，initial boiling point ≤35℃
|
|
2
|
Flash point ＜23℃，initial boiling point ＞35℃
|
|
3
|
23℃≤ Flash point ≤60℃
|
|
