What it regulates

It approves the APQ chemical-storage regulation and its technical instructions. This entry covers duties linked to worker safety: safe operation, emergencies, training and protection from hazardous chemicals. Examples from ITC APQ-10 concern storage in portable containers.

Who it applies to

OSH selection: Articles 7 and 11 of the regulation and Articles 11–13 of ITC APQ-10. Application depends on the product, quantities, container, exclusions and relevant technical instruction. The entire industrial APQ framework is not treated as labour law, and APQ-10 rules are not extended to every storage installation.

Key provisions

Article 7 makes the holder responsible for compliance and correct operation. Inspections do not release the holder from maintaining installations in the required condition.

Article 7

Article 11 requires a self-protection plan in the specified cases and preserves Article 20 of the OSH Act. Assigned personnel must know the plan, participate in keeping it effective and have emergency response and first-aid resources.

Article 11

ITC APQ-10, Article 11, requires accessible written procedures, instruction on products, safety equipment and responses to leaks or spills, visible emergency information and training records.

Article 11

ITC APQ-10, Article 12, refers PPE selection and use to the OSH Act, Royal Decree 773/1997 and safety data sheets. The need for and suitability of equipment must be assessed against the specific risk.

Article 12

ITC APQ-10, Article 13, requires avoiding skin contact, ingestion or inhalation of hazardous products. Emergency showers and eyewashes must be within 10 metres of the specified handling stations, unobstructed and marked; portable alternatives require proper justification in the technical documentation.

Article 13

Transitional provisions and application notes

  • Earlier installations are reviewed against the technical requirements under which they were built, while inspection frequency and criteria follow the 2017 instructions. Each installation’s dates and documentation must be checked.

    Transitional provision third
  • Transitional provision two allowed up to two years for specified installations already under construction when the regulation commenced. This historical transition does not create a new period for present projects.

    Transitional provision second
  • Article 11 retains references to Royal Decree 393/2007. The new directive published by Order INT/1068/2026 took effect on 11 October 2026 and allows up to four years to adapt existing plans. Thresholds, transitions and regional rules must be checked against that current framework; the OSH Act continues to apply.
