Which statement regarding industrial foam pumpers is accurate?

Industrial foam pumpers are specialized firefighting apparatus designed to handle different types of fires, particularly those involving flammable liquids, which are categorized as Class B fires. The accurate statement points out that these pumpers are built according to both NFPA 11C and NFPA 1901 standards.

NFPA 11C provides specific guidelines for the design and performance of foam concentrate delivery systems, ensuring that foam can be effectively used in various situations. NFPA 1901 outlines the standards for motorized fire apparatus, ensuring that vehicles are equipped to deliver water and foam efficiently. Together, these standards ensure that foam pumpers are capable of proper operation in the field and meet safety and performance requirements.

This highlights the importance of compliance with multiple standards to ensure the equipment can effectively combat both flammable liquid fires and other specific fire scenarios. The other options do not accurately reflect the comprehensive nature of the standards that govern the design and operation of industrial foam pumpers.
