Which factor is NOT considered when determining whether to consult a qualified person?

When determining whether to consult a qualified person, noise levels are not typically considered a critical factor. The key aspects that often necessitate expert consultation involve physical conditions directly impacting safety and operational integrity. Factors such as wind speed can affect how equipment operates, especially in outdoor settings where cranes or lifts are used. Soil conditions are essential for assessing stability and safety for any equipment or structures placed on or near it. Equipment stability itself is crucial, as it determines whether the machinery can operate safely under existing conditions.

In contrast, while noise levels can affect communication and concentration, they do not present the same immediate safety risks or operational limitations that the aforementioned factors do. Thus, noise levels are not a primary consideration when deciding if consultation with a qualified person is necessary.
