(vi) potential ignition sources (including electrical equipment).

Examples Gasoline (petrol) is a fuel for use in a spark ignition engine.

Safety actions are necessarily linked to the type of hazard which exists, e.g., flammable liquids should be stored away from ignition sources.

To design a safer machine with its structure around the engine, the pair wrote to German ignition specialist Robert Bosch for advice on a different electromagnetic system.

The National Ignition Facility, or NIF, is a large laser based inertial confinement fusion (ICF) research device, located at the Lawrence Livermore National Laboratory in Livermore, California.

A small number of large scale nuclear fusion systems also exist including the National Ignition Facility in the USA, JET in the UK, and soon the recently started ITER experiment in France.
