Certified Fire Inspector II Complete Practice Test 2025

The category of flammable liquids that includes types IA, IB, and IC is Type I. This classification pertains to liquids that have a flash point below 73°F (23°C) and a boiling point below 100°F (38°C). These liquids are considered more hazardous due to their low flash points, which means they can produce flammable vapors at relatively low temperatures, making them more susceptible to ignition.

Type IA denotes liquids with a flash point below 73°F and a boiling point below 100°F, Type IB consists of liquids with a flash point below 73°F but a boiling point at or above 100°F, and Type IC includes liquids that have a flash point at or above 73°F but below 100°F. Therefore, knowing that types IA, IB, and IC are all classified under Type I emphasizes their potential fire risks and the precautions required when handling them.

The other classifications, Types II, III, and IV, refer to liquids with higher flash points, thereby presenting different risks and handling guidelines, which are not applicable to this question about types IA, IB, and IC.
