What it regulates

Regulated public-health measures against Legionella from 2003 until its replacement in 2023. It expressly referred to workplace protection from biological and chemical agents and safety requirements for treatment operators. This entry supports reading programmes, records and actions from that period.

Who it applies to

Historical selection for maintenance, cleaning, disinfection and other staff exposed to aerosols or chemicals. Installation scope is retained as context; the entire health framework and its old technical references are not presented as current. The successor is Royal Decree 487/2022.

Key provisions

Section 9 referred to Royal Decrees 664/1997 and 374/2001 for prevention of biological and chemical risks. The installation’s health-control programme did not remove these occupational duties.

Article 9

Outsourcing maintenance did not release the holder from responsibility. Programmes had to organise resources and responsibilities so tasks could be performed effectively with minimum risk.

Article 4

Maintenance included checking, treatment, cleaning and disinfection, with products, doses, precautions and records. Duties had to be allocated to in-house or contracted personnel and the necessary resources provided.

Article 8

The 2010 amendment required physical and physicochemical systems not to endanger operators or others and their operation to be checked. It also referred to biocide competence, labelling and safety data sheets for substances and mixtures.

Article 13

Transitional provisions and application notes

  • From 2 January 2023, the requirements and transitions of Royal Decree 487/2022 must be consulted. The former installation classification and 2003 adaptation deadlines do not automatically carry over into the current regime.

    Official reference
  • Courses and qualifications under the historical system do not by themselves demonstrate current competence for every task. Role, validity and successor transitions must be checked; the 2010 reference to Royal Decree 830/2010 also needs to be read in its time context.

    Article 13
  • Certain installation adaptations were due within one year of the 2003 commencement. These are historical deadlines, not fresh extensions for installations existing today.
