Which potential source of ignition should be considered when an ambulance is parked off the roadway in a field of dried grass?

The catalytic converter is a crucial component of a vehicle's exhaust system that helps control emissions. When a vehicle runs, the catalytic converter reaches high temperatures due to the chemical reactions that take place inside it to convert harmful gases into less harmful emissions. If an ambulance is parked off the roadway in a field of dried grass, the extreme heat radiating from the catalytic converter can easily ignite the dry grass, posing a significant fire hazard.

While other sources of ignition like engine heat or overheating tires can pose risks in certain contexts, the catalytic converter is particularly relevant when discussing the potential for igniting flammable materials in proximity to a vehicle. Its direct connection to the exhaust system and the conditions under which it operates make it a significant concern in situations involving dry vegetation.
