What do Class A pumpers have according to NFPA 1901 standards?

Class A pumpers are defined by NFPA 1901 standards as vehicles that are designed primarily for fire suppression. According to these standards, a Class A pumper must be equipped with specific components that enable it to effectively respond to and manage firefighting operations. The inclusion of a hose bed, water tank, and pump is essential because this configuration allows the pumper to carry sufficient fire hose and a supply of water to fight fires directly.

The hose bed stores the various sizes of hoses needed for different types of firefighting situations, the water tank provides a readily available source of water for extinguishing fires, and the pump is crucial for delivering pressurized water to the hoses. This combination is vital for rapid deployment and effective firefighting tactics, ensuring that firefighters have the necessary tools to combat fires efficiently.

The other choices, while they may represent features that could be found on various firefighting equipment, do not capture the essential requirements set forth by the NFPA for Class A pumpers. Therefore, the correct answer highlights the fundamental equipment that defines a Class A pumper according to established fire service standards.
