Abstract: The ergonomics of personal protective equipment (PPE) involves complex interactions between the equipment, the human body, and the environment. It plays a critical role in ensuring the safety of firefighters and enhancing their operational efficiency. A key challenge in evaluating PPE ergonomics lies in the precise quantification of the impact of equipment on human function and performance in specific environments. Effective quantitative analysis depends on the accurate measurement of kinematic, dynamic, and physiological parameters while the equipment is worn. Recent advancements in evaluation technologies have led to significant progress in ergonomics research, particularly in areas such as joint mobility, balance ability, and biomechanics. This paper outlines an ergonomic evaluation framework, systematically reviews existing methods, and summarizes their current state. Furthermore, it anticipates future trends in ergonomic evaluation methodologies.
