Industrial foam pumpers are built according to which standards?

Industrial foam pumpers are designed to meet specific standards that ensure their effectiveness and safety in handling firefighting foams. NFPA 11 provides the standard for the selection, installation, and maintenance of foam systems, which is critical for foam pumpers that require the appropriate equipment to deliver foam effectively in various industrial settings. This standard outlines the necessary properties of foam and the delivery systems to be used in combination with water-based firefighting operations.

On the other hand, NFPA 1901 establishes the minimum standards for fire apparatus, including the design and performance of pumpers. This standard covers various aspects of fire apparatus safety, including construction requirements, pump performance, and water tank capacity, which are vital for ensuring that industrial foam pumpers operate reliably and effectively under extreme conditions.

Therefore, because industrial foam pumpers need to adhere to both the criteria for foam handling established in NFPA 11 and the operational standards found in NFPA 1901, the correct response encompasses compliance with both standards concurrently.
