Ignition source
A source of ignition is the energy that triggers oxidation , usually combustion . A flammable mixture of gases , vapors or dusts must already be available for this.
An ignition source is effective if it can trigger an ignition in the potentially explosive atmosphere under consideration .
species
The following energies can be considered as ignition sources: hot surfaces , flames , mechanically generated sparks , electrical systems without appropriate protection, static electricity , lightning strikes , electromagnetic fields , electromagnetic radiation , ionizing radiation , ultrasound , adiabatic compression and chemical reactions . In the event of an explosion , the ignition energy is supplied depending on the explosive used (e.g. electric detonators for dynamite ).
