Blood pathogens biological exposure (B.P.B.O) and specially needle stick injury is the most common accident in the sanitary field. Objectives: The main objective of this research is to check the level of sinestry in this kind of accidents among temporary workers and analyse if there is a certain profile.  Methodology: All accidents with biologic risks happened in a year were analised in the University Hospital "La Princesa" . A logistic regression was performed where the dependent variables to study were: age, sex, grade, place of the accident, seniority, injured body part, producing agent, working shift, way in which it´s caused, month and day of the injury.  Results: There is a relative risk of 1.96 (1.48.- 2.60) higher to happen an B.P.B.O in a temporary worker. Over the other variables studied in the multivariable analysis, no significant differences are detected, but an increase of B.P.B.O among workers in September. Conclusions: Although there is almost twice the risk of a biological accident among temporary workers, there are no significant diferences in the variables studied over the both kind of workers.
