Nozzles suitable for service testing are usually categorized as which type of equipment?

Nozzles that are used for service testing are primarily categorized as regular equipment on the fire apparatus. This is because they play a crucial role in the delivery of water during firefighting operations. Service testing is an essential process that ensures the nozzles are functioning properly and can deliver the required flow and pressure when needed.

By being classified as regular equipment, it emphasizes their integration into daily firefighting operations rather than being reserved for specific situations like training or rescue. Regular equipment is routinely maintained and checked, which includes items like nozzles that must perform reliably under the conditions encountered during actual fire responses. While other types of equipment may have specific uses or contexts, the nozzles are fundamental components of the fire apparatus that are expected to be used regularly in the field.
