What is the maximum volume of Class I, Class II, and Class III A liquids allowed to be stored in an individual storage cabinet?

According to NFPA 30, Flammable and Combustible Liquids Code, the total combined quantity of Class I, Class II, and Class IIIA liquids permitted to be stored in a single storage cabinet shall not exceed 120 gallons (460 L). The code further stipulates that within this total, the quantity of Class I and Class II liquids combined cannot exceed 60 gallons (230 L). The question asks for the maximum total volume, which is 120 gallons.

A. 80 gal (303 L) is an incorrect value that is below the maximum allowable quantity specified by NFPA 30 for a storage cabinet.

B. 100 gal (379 L) is an incorrect value that is below the maximum allowable quantity specified by NFPA 30 for a storage cabinet.

D. 140 gal (530 L) is an incorrect value that exceeds the maximum allowable quantity specified by NFPA 30 for a storage cabinet.
