OBJECTIVE: to analyze occupational accidents with exposure of nursing technicians to biological material in a school hospital.
METHOD: nursing technicians were invited to answer a questionnaire related to occupational accidents with biological material.
RESULTS: 275 professionals from 9 hospital units participated. 76% reported having suffered an accident and the variables "age group" and "employment regime" showed a significant association for accidents (p<0.05). Those hired by the Consolidation of Labor Laws (CLT - Consolidação das Leis do Trabalho) employment regime were 3.5 times more likely to suffer accidents (p=0.04) and institutional capacity building did not show statistical significance (p>0.05).
CONCLUSION: the increase in the number of training did not ensure the reduction of occupational accidents with biological material; and nursing technicians under the age of 30 were more vulnerable. Professionals with a CLT labor contract were more affected than the statutory employees.
