Question 1331 Deck General

The correct answer is C) 40. Liquefied flammable gas is defined as any flammable gas having a Reid vapor pressure exceeding 40 pounds per square inch (psi). This definition is based on the regulations in Title 46 of the Code of Federal Regulations (CFR), which govern the U.S. Coast Guard licensing and certification requirements. The other answer choices are incorrect because 14 psi is the threshold for defining a flammable liquid, 30 psi is not a recognized threshold, and 50 psi is too high for the definition of liquefied flammable gas.
