Final answer:
The development of a fire in the incipient stage depends largely upon the availability of oxygen, fuel type and quantity, and ambient temperature.
Step-by-step explanation:
The development of a fire in the incipient stage depends largely upon:
- Availability of oxygen: Fire requires oxygen to burn.
- Fuel type and quantity: Different types and quantities of fuel will affect the intensity and spread of the fire.
- Ambient temperature: Higher temperatures can facilitate the ignition and propagation of the fire.
The presence of firefighters may affect the mitigation and extinguishing of the fire, but it is not a factor in the initial development of the fire.
