Which condition would classify a fire as a Primary Fire?

• A. Grassland fires
• B. Any fire attended by five or more pumping appliances
• C. Fires in derelict buildings
• D. Indoor office fires

Answer: (B)

Primary Fire is defined by the scale of firefighting response, indicating a major incident that requires substantial resources. The key measure used is how many pumping appliances (fire engines) are in attendance. When five or more pumping appliances are at the scene, the fire is classified as a Primary Fire because it signals a large, resource-intensive incident with higher complexity and risk. The other scenarios describe where a fire occurs, but they don’t inherently reflect the level of firefighting resource needed. Grassland fires, fires in derelict buildings, or indoor office fires can vary greatly in size and resource demand, so they don’t alone define a Primary Fire.
