Kipinänlähteet refers to ignition sources, which are conditions or objects capable of initiating a fire or explosion. Understanding different types of ignition sources is crucial for fire prevention and safety protocols.

One common category is electrical ignition sources. This includes faulty wiring, short circuits, overloaded circuits, and static electricity discharge. The heat generated by electrical faults can be sufficient to ignite flammable materials. Sparks from electrical equipment, such as grinders or welding operations, also pose a significant risk.

Open flames represent another direct ignition source. This encompasses matches, lighters, candles, and pilot lights. Careless use or proximity of open flames to combustible substances is a leading cause of fires.

Mechanical ignition sources can arise from friction or impact. For instance, friction between moving parts in machinery can generate sufficient heat to cause ignition. Similarly, sparks produced by the impact of hard materials, like rocks or metal, can ignite flammable atmospheres.

Chemical ignition sources involve spontaneous combustion or exothermic reactions. Certain materials, when exposed to air or water, can undergo chemical reactions that release heat, leading to self-ignition. This is particularly relevant for substances like oily rags or certain chemicals.

Thermal ignition sources include hot surfaces. Equipment operating at high temperatures, such as engines, stoves, or heating elements, can ignite nearby flammable materials if proper clearances are not maintained.

Finally, spontaneous combustion is a specific type of ignition where a material ignites without an external spark or flame, due to internal heat generation from oxidation or microbial activity.
