What it regulates

Organises the inspection system and its powers. For occupational health and safety it covers prevention enforcement, investigation of occupational accidents and diseases and measures addressing non-compliance.

Who it applies to

A law of general scope across labour and social-security matters; this record selects its occupational health and safety functions. State and regional responsibilities and special rules for certain workplaces must be respected.

Key provisions

Enforce prevention and legal-technical rules affecting working conditions and investigate occupational accidents and diseases.

Article 12

Inspectors may visit workplaces, request information and conduct tests; entry into an individual’s home requires express consent or judicial authorisation.

Article 13

The Occupational Safety and Health sub-inspector scale checks material conditions, technical rules and prevention programmes and provides advice within its powers and supervision arrangements.

Article 14

Document inspections in written records and involve worker representatives where required; the law prohibits requiring inspected parties to obtain or have books officially endorsed for that purpose.

Article 21

Depending on the findings, measures include requiring correction, initiating penalties, proposing benefit surcharges and ordering an immediate stoppage where prevention breaches create serious and imminent danger.

Article 22

Transitional provisions and application notes

  • The initial regime retained services, staff and appropriations pending establishment and resourcing of the new body. Royal Decree 192/2018 approved its statutes; it must not be described as still awaiting creation.

    Transitional provision first
  • The penalty-jurisdiction rule retains the prior regime pending implementing rules for LISOS Article 48(1). Identifying today’s competent authority requires current procedural rules and territorial responsibilities, not the transitional provision alone.

    Transitional provision second
  • The entry-qualification transition ended on 1 January 2019 for the Employment and Social Security scale. It did not apply to the new Occupational Safety and Health scale.

    Transitional provision third
  • It repealed Law 42/1997; earlier regulations survive only insofar as they do not conflict with this law, until amended or repealed.

    Repealing provision sole
  • The 2018–2020 plan in the history is historical. Publication of the 2025–2027 Strategic Plan by the Resolution of 8 September 2025 has been verified; a plan does not replace statutory powers and safeguards.
