Purpose. To verify the relationship between stress indicators and the age and years of service of military firefighters from the fire rescue corps of the metropolitan area of the state of Sao Paulo. Methods. Forty military firefighters with the mean age of 37.9 ± 5.4 years, from the 1st, 2nd and 8th fire brigades of the metropolitan area of Sao Paulo participated in this study. All underwent clinical, physical and psychological evaluations to verify the relationship between the age and years of service with the variables of levels of stress (tension, depression, anger, vigor, fatigue, confusion and total stress) on workdays and on days off. Results. On workdays, the mean scores for tension, depression, fatigue and stress were overall higher compared to those on days off. The older the firefighter, the higher the levels of stress, depression, anger and total stress. The more years of service, the greater the depression and anger. Conclusions. The levels of stress were high on workdays. Chronological age and years of service influenced the increase in the scores of stress.

Analizie poddano 841 wypadków zaistniałych w dwóch kopalniach węgla kamiennego, w których na trzech zmianach, w czasie sześciu lat zatrudnionych było 32801 osób. Wykazano statystycznie, że w czwartej lub piątej godzinie pracy dochodzi do największej liczby wypadków oraz że istnieje trend wzrostu liczby wypadków do pewnej wartości maksymalnej wraz z upływem kolejnych godzin pracy, który następnie maleje.

The analysis included 841 accidents in two black coal mines employing for six years 32801 people. It has been statistically proved that in the fourth and fifth hour of work occur most accidents and that there is a rising tendency of accidents up to a certain maximum value as working hours wear on. This tendency subse-guently diminishes.
