The "Human Factors Theory of Accident Causation" emphasizes that many accidents occur primarily due to human error, which can stem from overload, inappropriate responses, and unsuitable activities. This theory suggests that individuals may not perform optimally under certain conditions, such as when they experience excessive cognitive load or are faced with tasks beyond their abilities. This can lead to mistakes that contribute significantly to accidents.

By focusing on human factors, this approach seeks to understand how psychological and physical aspects can influence behavior and decision-making processes. For instance, if a worker is overwhelmed with tasks or receives inadequate training, they may misinterpret signals or instructions, leading to unsafe behaviors and, ultimately, accidents. This holistic view highlights the need for better training, improved workplace design, and systems that account for human limitations, aiming to reduce error and enhance safety.

The other options, while they can certainly contribute to accidents, do not align with the core premise of the Human Factors Theory, which centers on human actions and decisions as the primary cause of mishaps in construction and other industries.
