What is an example of engulfment in a confined space?

Engulfment in a confined space refers to being surrounded or overwhelmed by a substance such that escape becomes impossible. In this context, drowning in a pit is a prime example of engulfment because the individual is submerged in a liquid, which completely surrounds them and inhibits their ability to breathe or escape. This scenario exemplifies how the individual can be overtaken by a substance—in this case, water—which leads to life-threatening situations.

Being surrounded by toxic gas does pose significant risks, but it is more closely associated with inhalation hazards rather than engulfment. Similarly, being trapped under machinery is about being physically restrained rather than being surrounded by a substance. Exposure to high heat is a serious hazard but does not fit the definition of engulfment, as it does not involve being enclosed or overtaken by a material that can completely envelop someone. Thus, drowning in a pit accurately captures the essence of engulfment and represents a critical safety concern in confined spaces.
