Labelling Project

Plants identification and labelling based on Legislative decree 81/08, annex XXVI (UNI 5634/97)

Very often, the identification of plants (pipes, valves, pumps, fuse and control boxes, equipment, etc.) is difficult to achieve according to law, because the identification is incomplete, sometimes totally lacking or homemade like, for example, using markers, spray paints, laminated sheets or multicolored adhesive strips.

The ever greater downsizing, unlike the increasing number of works, doesn’t allow to devote internal resources in order to comply with the plants labelling regulation.

Labelling is not only a legal requirement, but it is also a basic requirement requested by certification bodies and an insurance obligation.

Pu.Ma. Trading was asked to address and solve these issues by its major customers, by developing the “ZERO COST LABELLING PROJECT”.

This consist of:

  • Classification of the fluids to be identified;
  • Drawing up the list of required materials in order to make the identifying marks;
  • Issuing order by the customer for required materials to make the identifying marks;
  • Zero cost production on site of identifying marks by Pu.Ma. Trading technicians;
  • Delivery to operator in charge of plants of the identifying marks for the displaying.

Pipes identifying layout is made according to Legislative decree 81/08, annex XXVI and therefore states:

  • Background color according to UNI5634/797;
  • Arrows that indicates the fluid direction;
  • Fluid name;
  • GHS/CLP Pictogram;
  • Temperature and pressure;
  • Diameter of the line;
  • Fluid departure and arrival.

Legislative decree 81/08, annex XXVI, requires that […] visible pipes that contain or carry hazardous substances or preparations, have to be equipped with labelling provided for by the rules (pictogram or symbol on the background colour – Ref. UNI5634/97). […] Labelling may be supplemented by additional informations, such as the name or formula of the hazardous substance or preparation and the details of the hazard. […] Labelling used on pipes must be visible and close to the most dangerous spots, such as valves and junction points and it must appear several times.
