What is a workplace accident?
Article 156 of the General Social Security Law defines a work-related accident by three elements: a bodily injury, a work activity, and a relationship between the two. The injury may be physical or psychological and result from a fall, blow, entrapment, acute exposure, assault, or other event. Unless proven otherwise, an injury sustained during working hours and at the workplace is presumed to be work-related.
The existence of sick leave does not, in itself, determine whether an accident has occurred. An injury can be classified as a workplace accident even if it does not result in a prolonged absence; sick leave affects its administrative and statistical processing, but it does not eliminate the preventive need to determine the causes.
Included assumptions and exclusions
Spanish regulations include, among others, commuting accidents; accidents occurring while performing union duties; accidents occurring while carrying out other tasks as ordered by the company or in the interest of proper functioning; and work-related rescue operations. They also cover certain illnesses caused exclusively by work that are not included in the list of occupational diseases , as well as the aggravation of pre-existing conditions due to an accident.
Force majeure completely unrelated to work is excluded, as is, in general, intent or reckless imprudence on the part of the injured party. Professional negligence associated with the confidence acquired in a routine task does not automatically preclude classification as a work-related injury. Each case requires verification of the facts and causal link.
Differences with related concepts
- Occupational risk: the possibility of harm occurring. It exists before the event; the accident is its materialization with a harmful result.
- Workplace incident: an event related to work that does not cause injury, although it could have. Investigating it allows for action to be taken before harm occurs.
- Occupational disease: an illness contracted in the course of activities and by agents included in the corresponding regulatory framework. An illness outside this framework may be classified as a work-related accident if it is proven that the work was its sole cause.
- Accidents with or without sick leave: an administrative distinction. Preventive damage investigations should not be limited to cases involving sick leave.
How to act in case of an accident
- Protect and care: activate first aid and urgent assistance, control the hazard and prevent further exposure.
- Communicate internally: inform the command and the preventive system, preserving facts, testimonies and evidence without hindering assistance.
- Notify through the applicable channel: process the sick leave report or the accident report without sick leave through the official system. The Order of December 16, 1987 (Article 3.a) establishes a maximum period of five working days for the sick leave report, counted from the date of the accident or from the date of the medical leave.
- Communicate urgently when appropriate: the maximum time limit is 24 hours for certain fatal, serious, very serious accidents or those affecting more than four people.
- Investigate and correct: reconstruct the event, determine causes, assign measures, responsibilities and deadlines, and verify their effectiveness.
The specific rating and deadlines must be reviewed in the regulations and through the appropriate channel for the case.
How to investigate and prevent recurrence
The investigation must begin promptly and gather information from the injured person, witnesses, the location, equipment, materials, procedures, training, supervision, and work organization. Its purpose is to determine what happened and why, not to assign blame. The INSST emphasizes that accidents are usually caused by multiple factors: reducing the analysis to “human error” prevents the detection of design, maintenance, coordination, or control failures.
The findings should inform the risk assessment and planning. Measures are prioritized at the source: eliminating the hazard, replacing it, implementing collective protection measures, and organizing work before relying on individual instructions or equipment. Equivalent situations in other positions and locations are also reviewed, and traceability of decisions and verifications is maintained.
Practical example
In a warehouse, a forklift strikes a person preparing orders in a shared aisle, causing a fracture. There is an injury and a direct link to work activity, therefore the incident falls under the definition of a workplace accident.
The investigation is not limited to driver behavior. It analyzes the coexistence of pedestrians and vehicles, road width and visibility, speed, signage, procedures, time constraints, and supervision. The decision is made to physically separate routes, redesign intersections, control speed, and reinforce training. The evaluation is then updated, the implementation is checked, and it is verified whether incidents and deviations in similar situations decrease.
Regulatory framework and European statistical difference
In Spain, Article 156 of the General Social Security Law governs the legal concept. Law 31/1995 mandates investigating damages to determine their causes, organizing emergency response, maintaining documentation, and issuing the corresponding notifications. Order TAS/2926/2002 establishes official forms and electronic transmission via Delt@.
In the European Union, Directive 89/391/EEC establishes the preventive framework, and Regulations (EC) 1338/2008 and (EU) 349/2011 underpin the ESAW statistics. ESAW defines an accident as a specific event during work that causes physical or mental harm and, for its main data, records fatalities or cases resulting in more than three days of absence. It excludes commuting accidents, while Spain recognizes commuting accidents; therefore, the figures should not be compared without reviewing coverage and methodology. The 2002 Protocol to ILO Convention 155 provides the international reference for recording and reporting.
