In confined spaces, which cause of death has the lowest percentage?

The choice indicating "Other" as the cause of death with the lowest percentage is correct because it encompasses a wide array of uncommon hazards that do not frequently result in fatalities compared to the more common risks associated with confined spaces.

Confined spaces pose specific dangers related to environmental hazards, such as lack of oxygen, toxic gas exposure, and physical risks like engulfment or being struck by objects. Cases of heat stress or exposure can occasionally occur, but the statistics indicate that they are less significant in confined spaces than the more direct hazards.

Engulfment, particularly in materials like liquids or loose solids, is one of the leading causes of fatalities in these environments and is well-documented. Similarly, being struck by falling objects is a recognized hazard in many work environments, including confined spaces, where movement is limited.

By contrast, the category of "Other" includes incidents that are less typical, such as those outside the primary hazards associated with confined spaces, leading to a lower overall incidence of fatalities. This makes it the correct answer in the context of identifying the cause of death with the lowest percentage.
