Classification of zones with the risk of explosion

Type of substance   Zone   Description
       

Gas, vapours or mists

  0  

Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are present continuously or for long periods of time.

       
  1  

Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are likely to occur occasionally during normal operation.

       
  2  

Areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists are not likely to occur or only occur infrequently or for short periods of time.

       

Dust

  20  

Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is present continuosly or for long periods of time or frequently.

       
  21  

Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is likely to occur occasionally during normal operation.

       
  22  

Areas in which an explosive atmosphere in the form of a cloud of combustible dust in the air is not likely to occur occasionally during normal operation but, if it does occur, will persist for a short periodonly.
