What is considered an example of an ignition source?

An ignition source is defined as any material or condition that can cause fuel to ignite. Exposed electrical wiring, in this context, is a clear example of an ignition source because it can create sparks or arcs when contact is made, leading to a potential fire if it comes into contact with flammable materials. Electrical faults, such as short circuits in exposed wiring, can generate enough heat or electrical discharge to ignite surrounding materials, making it a significant fire hazard.

In contrast, water is not an ignition source but rather a fire suppressant. While wood materials can serve as fuel for a fire, they do not initiate it on their own; similarly, oily surfaces can support combustion but require an ignition source to actually catch fire.
