The Spanish model of work injury insurance is administered through employers' associations authorized by the Ministry of Labour and Social Security. These associations, known as Mutual Funds, collect fee contributions from employers to cover occupational risks. The Mutual Funds provide general services funded by these fees, such as informing companies of their obligations, investigating accidents, and providing training. They also offer additional prevention services for a separate fee, such as risk evaluations, medical measurements, and specialized training. The Mutual Funds employ over 5,000 health and safety technicians and have an annual budget of over 6 billion euros to administer work injury coverage, prevention services, and rehabilitation care through specialized medical units.
