  1. The reduction in risk by the plant designers taking all hazard risks into account.
  2. The installation of the electrical apparatus in a non-Explosive Atmosphere, or if this is not possible in the least Explosive Atmosphere.
  3. The electrical apparatus and its wiring and connections shall be designed, installed, operated and maintained in such a way to prevent it from becoming a source of ignition.
Furthermore in respect of the electrical equipment that is installed, the following should also be observed :-
