"Spain itself did not register any case of occupational disease. The number of accidents was 114, of which 41 entailed medical leave and 73 did not, indicating a very low rate of work-related accidents, with levels below the sector average. Thus, the Bank's severity index is 0,04 (0.03 men and 0.05 women) in 2021, while the frequency index is 0.89 (0.64 men and 1.12 women). In the case of accidents with medical leave, the main types of injuries have been sprains and strains, superficial injuries and foreign bodies in the eyes and closed fractures."
