Influence of ergonomic conditions and occupational risk factors on the physical performance of operational personnel at the Loja North Fire Station.

Abstract

This article analyzes how ergonomic, environmental, and psychosocial conditions influence the overall health and physical performance of operational personnel in the Loja Fire Department. The study revealed that firefighting demands extreme physical exertion, characterized by the constant handling of heavy equipment, awkward postures, and shifts requiring a rapid and effective response in high-risk environments. These factors generate progressive wear and tear, manifesting muscle discomfort, fatigue, and decreased functional capacity. Furthermore, it was identified that environmental conditions such as intense heat, smoke exposure, internal moisture in the protective gear, and limited visibility affect both the physical endurance and mental clarity of operational personnel. These repeated exposures not only impact immediate performance but can also lead to respiratory, cardiovascular, and thermal complications over time. On an emotional level, the study reveals that work-related stress, psychological exhaustion, and continuous exposure to traumatic events are part of the daily reality for firefighters. These experiences influence their personal well-being, motivation, and ability to concentrate during emergencies. Therefore, the overall health of firefighters requires a preventative approach that combines ergonomics, emotional support, safe environmental conditions, and institutional policies that promote physical and mental protection. This analysis aims to contribute elements that will strengthen the safety and well-being of operational personnel in their daily work.
