Purpose and description
Enable an agent to recognise a fire engine, assess its readiness for a specified firefighting task, and identify actions permitted by its equipment, condition and operating limits.
A fire engine is a road vehicle equipped to carry firefighters and firefighting equipment to incidents and, in its narrower operational sense, to pump water or other extinguishing agents through hose lines.
It can be Check whether a configured engine can reach an incident location and use the available water source.; Compare documented pump capability with a specified flow and pressure requirement.; Estimate onboard-water endurance under explicit discharge and replenishment assumptions.; Identify compatible hose, inlet and agent connections from verified specifications.; Determine whether recorded faults or missing equipment restrict a proposed firefighting task.; Identify required inspection, replenishment or qualified maintenance before returning the engine to service..
Distinguishing features
Check for an integrated firefighting water-delivery system, including pumping equipment and hose connections, rather than identifying the vehicle from colour or warning lights.
Distinguish an engine from a water tender by its intended suppression and hose-supply role; carrying a large water tank alone does not establish engine identity.
Distinguish an engine from a dedicated aerial appliance by its principal operational role, while recording combination apparatus explicitly.
Distinguish an engine from a rescue or command vehicle by installed suppression capability rather than shared crew space or emergency markings.
Separate the apparatus kind from a manufacturer's model designation and from an individual vehicle identified by a fleet number or chassis identifier.

Characteristics
- Apparatus role and configuration
- Locally recognised apparatus class, primary role and secondary capabilities Determines whether the vehicle belongs to this kind and which operational capabilities require assessment.
- Pump performance envelope
- Flow in L/min at specified discharge pressure in kPa, with suction conditions and test basis A flow figure without pressure and supply conditions cannot establish hose-supply capability.

- Onboard tank, pressurised external supply or drafting, with supported connection specifications Establishes whether an available source can actually feed the apparatus.
- Hose and outlet configuration
- Outlet count; hose length in m; hose bore in mm; coupling designation Constrains compatible connections, deployment reach and delivery losses.
- Extinguishing-agent system
- Water-only or documented additional agent systems, compatible agents and proportioning range Prevents assuming that every engine can produce or deliver every extinguishing medium.

- Number of approved seated and restrained occupants Distinguishes available crew transport capacity from the staffing an incident requires.
- Suppression readiness
- Ready, restricted, unavailable or unknown, for a named task and assessment time Roadworthiness alone does not demonstrate firefighting readiness.

- Issuing body, document identifier, edition, jurisdiction, applicability and linked inspection or conformity record Connects a claimed operating limit or compliance status to evidence appropriate to that apparatus.
