Accident Investigation Form Spain (Formulario de Investigación de Accidente)

An Accident Investigation Form Spain (Formulario de Investigación de Accidente de Trabajo) is a structured document used by Spanish employers to systematically analyse the causes of a workplace accident (accidente de trabajo), identify contributing factors, and define corrective and preventive measures, as required by Ley 31/1995 de Prevención de Riesgos Laborales (LPRL) Article 16, which obliges employers to investigate accidents and incidents in the workplace and to adopt measures to prevent their recurrence.

Ley 31/1995 (LPRL) is the foundational statute of Spanish occupational health and safety law, transposing European Directive 89/391/CEE (Marco Directive on Safety and Health at Work) into Spanish law. Article 16 LPRL requires employers to maintain an active sistema de gestión de la prevención de riesgos laborales, including procedures for investigating accidents to determine their causes and to update the empresa's evaluación de riesgos laborales accordingly. Real Decreto 39/1997 (Reglamento de los Servicios de Prevención — RSP) and Real Decreto 1627/1997 (construcción sector) set out the detailed requirements for the prevention management system.

A workplace accident (accidente de trabajo) in Spain is defined by Article 115 of the Ley General de la Seguridad Social (Real Decreto Legislativo 8/2015) as any bodily injury suffered by a worker as a consequence of work performed as an employee. This includes accidents occurring at the workplace, accidents in itinere (on the commute between home and work), and occupational diseases (enfermedades profesionales) listed in Real Decreto 1299/2006. Employers must notify accidents to the Mutua Colaboradora con la Seguridad Social (Mutua) and to the Seguridad Social through the Delt@ system (Declaración Electrónica de Accidentes de Trabajo) managed by the Ministerio de Trabajo y Economía Social.

Under Article 23 LPRL, employers must document their accident prevention activities, including investigation results. The Inspección de Trabajo y Seguridad Social (ITSS) — the primary enforcement body for occupational safety under Ley Ordenadora de la Inspección de Trabajo y Seguridad Social (Ley 23/2015) — routinely requests accident investigation reports during workplace inspections and following serious or fatal accidents. Failure to investigate accidents or to take corrective action constitutes an infraction under Real Decreto Legislativo 5/2000 (LISOS), with fines ranging from €2,046 to €41,025 for serious infractions, and up to €819,780 for very serious infractions.

The Servicio de Prevención de Riesgos Laborales (SPRL) — whether internal (servicio de prevención propio), shared (mancomunado), or external (servicio de prevención ajeno) accredited under Real Decreto 39/1997 — is responsible for leading accident investigations and for updating the company's plan de prevención de riesgos laborales. Workers' safety representatives (Delegados de Prevención), elected under Article 35 LPRL, have the right to participate in accident investigations under Article 36.2(f) LPRL.

The legal framework governing the Accident Investigation Form Spain (Formulario de Investigación de Accidente) in Spain draws on several key statutes and regulatory bodies. Under the Estatuto de los Trabajadores (ET) RDL 2/2015, Spanish employment law governs contracts, dismissals, and working conditions. The Tesorería General de la Seguridad Social (TGSS) administers social security contributions. The Servicio Público de Empleo Estatal (SEPE) manages unemployment benefits. The Inspección de Trabajo y Seguridad Social enforces labour compliance. The Juzgados de lo Social hear employment disputes under the Ley Reguladora de la Jurisdicción Social (Ley 36/2011). Parties executing a Accident Investigation Form Spain (Formulario de Investigación de Accidente) in Spain should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Ley 31/1995 de Prevención de Riesgos Laborales, Article 16 sets the foundational requirements.

An Accident Investigation Form Spain is required after every workplace accident (accidente de trabajo) that results in injury, near-miss, or dangerous occurrence — regardless of severity — as part of the employer's mandatory prevention management system under Ley 31/1995 (LPRL) Article 16 and Real Decreto 39/1997 (RSP).

The form is mandatory after any accident resulting in a worker being unable to work for at least one day beyond the day of the accident (accidente con baja). Under Real Decreto 1273/2003 and the LPRL, such accidents must be notified to the Mutua Colaboradora and to the Seguridad Social through the Delt@ electronic system within 5 working days of the accident.

An Accident Investigation Form is required after accidents in itinere (commuting accidents) that involve injury — although the employer is not responsible for the accident itself, LPRL obligations require the employer to consider whether company policies on working hours or transportation may have contributed.

The form is also needed after any near-miss (accidente sin baja or incidente peligroso) — an event that did not result in injury but had the potential to do so. Real Decreto 39/1997 Article 9 requires employers to investigate incidents to prevent escalation.

In the construction sector, Real Decreto 1627/1997 imposes additional investigation and reporting obligations on the Coordinador de Seguridad y Salud. In companies where a Comité de Seguridad y Salud (joint employer-employee safety committee) operates — required when the workforce exceeds 50 employees under Article 38 LPRL — the committee has the right to know and be consulted on all accident investigations under Article 39.1(a) LPRL.

Parties in Spain should prepare a Accident Investigation Form Spain (Formulario de Investigación de Accidente) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under the Estatuto de los Trabajadores (ET) RDL 2/2015, Spanish employment law governs contracts, dismissals, and working conditions. The Tesorería General de la Seguridad Social (TGSS) administers social security contributions. The Servicio Público de Empleo Estatal (SEPE) manages unemployment benefits. The Inspección de Trabajo y Seguridad Social enforces labour compliance. The Juzgados de lo Social hear employment disputes under the Ley Reguladora de la Jurisdicción Social (Ley 36/2011). Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.
