El artículo analiza uno de los temas clave de la protección contra explosiones: las fuentes de ignición, que constituyen uno de los tres elementos principales del riesgo de explosión (junto con la sustancia combustible y el oxidante). Se destaca que sin una energía de ignición suficiente no puede producirse una explosión; por ello, eliminar o reducir las fuentes de ignición es una medida preventiva fundamental.
