Location Unregulated inside climate L2

The work performed is carried out indoors in a regulated environment, indoors in an unregulated environment, outdoors or in a vehicle. In many occupations, the Main Duties may be performed in more than one location. Therefore, a group may have more than one Location code, for example:

  • firefighting and fire prevention duties
  • maintenance of interior/exterior of buildings
